Climate Scientists sound the alarm in “Code Red” IPCC Report and WMO Atlas of mortality and economic damage

Alongside the continuing disaster of North America’s heat, drought, and wildfires has come Hurricane Ida on the Gulf Coast, U.S. Northeast, even as far as Quebec.  Only 4% of broadcast media in the U.S. linked Hurricane Ida to climate change – preferring to report on the flooding, storm surge, resulting power losses, evacuations, oil spills in the Gulf of Mexico, death and destruction.  Yet with less media attention, scientists worldwide have published recent studies unequivocally linking such weather extremes with climate change and human activity. Notable examples over the summer : 1.  Climate Change 2021: the Physical Science Basis, the first installment of the Sixth Assessment Report (AR6) by the U.N. Intergovernmental Panel on Climate Change (IPCC) Working Group I, 2. The WMO Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970–2019) released by the World Meteorological Organization on  August 31, and 3. The WMO Air Quality and Climate Bulletin , launched on September 1.

The world’s scientists issue a Code Red warning in the IPCC 6th Assessment

At almost 4,000 pages, the full IPCC report, Climate Change 2021: the Physical Science Basis, is a comprehensive compilation and assessment of the latest research  by the world’s scientists. More readable and less technical: the  Summary for Policymakers , or the official Fact Sheet .  The U.N. press release announcement was accompanied by warnings of the “Code Red”   situation:  irreversible climate-related damage is already underway across the world, and immediate, strong and sustained reductions in emissions of carbon dioxide and other greenhouse gases are urgently needed. The report was summarized widely: for example, in “Global Climate Panel’s Report: No Part of the Planet Will be Spared”  (Inside Climate News, Aug. 9); by Carbon Brief here ;  or by The Guardian here .  

An  analysis of coverage by 17  international newspapers found that Canadian news outlets, with the exception of the Toronto Star, were particularly poor at explaining the IPCC report – as summarized in “When Dire Climate News Came, Canada’s Front Pages Crumpled “ in (The Tyee, Aug. 19).  However, outside of the mainstream media, here are some noteworthy examples of Canadian news coverage:

Climate scientist John Fyfe explains why new IPCC report shows ‘there’s no going back’” (The Narwhal, Aug. 12)

It’s Code Red  for the Climate. Will BC Do Anything about It?” (The Tyee, Aug. 10)

Two blogs by David Suzuki in Rabble.caClimate report shows world pushed to the brink by fossil fuels”  and “IPCC report could be a legal game-changer for climate“(Sept. 1)

“IPCC warns of climate breakdown, politicians warn of each other” (National Observer, Aug. 9)

“U.N. Climate Report scapegoats “human activity” rather than fossil-fuel capitalism”  (Breach Media), which states: “We should welcome the latest IPCC Report for its scientific insight. But we should also understand it as an ideological document that obscures the crucial systemic causes of climate change. For advice on what social forces could push forward climate solutions, readers will have to look beyond the thousands of pages generated by the IPCC.”

Extreme weather disasters caused US$ 3.64 trillion, 2 million deaths between 1970 and 2019

A second new international scientific report is The WMO Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970–2019), released on  August 31 by the World Meteorological Organization. It aggregates and analyses statistics on world disasters, with continent-level breakdowns. It reports that there were more than 11,000 disasters attributed to weather, climate and water-related hazards between 1970 and 2019, accounting for just over 2 million deaths and US$ 3.64 trillion in economic losses. This represents  50% of all recorded disasters, 45% of related deaths and 74% of related economic losses over the last 50 years. Food for thought for those who say that fighting climate change is too expensive!  

The WMO Atlas includes an extensive discussion of current and new statistical disaster databases, and how they can be used to reduce loss and damage.  It also includes a brief explanation of “attribution research”, which seeks to determine whether disasters are human-caused. ( A recent article in Inside Climate News is more informative on the issue of attribution science, highlighting the research of the World Weather Attribution network, which has already published its findings about the German flooding in July 2021).

Finally, on September 3, the WMO also published the first issue of its  Air Quality and Climate Bulletin ,  highlighting the main factors that influence air quality patterns in 2020 – including a section titled “The impact of Covid-19 on air quality.”   The Bulletin concludes that there is “an intimate connection between air quality and climate change. While human-caused emissions of air pollutants fell during the COVID-19 economic turndown, meteorological extremes fuelled by climate and environmental change triggered unprecedented sand and dust storms and wildfires that affected air quality…. This trend is continuing in 2021. Devastating wildfires in North America, Europe and Siberia have affected air quality for millions, and sand and dust storms have blanketed many regions and travelled across continents.” 

In another section, “Global mortality estimates for ambient and household air pollution”  the new Bulletin states that global mortality increased from 2.3 million in 1990 to 4.5 million in 2019 (92% due to particulate matter, 8% due to ozone). Regionally, present-day total mortality is greatest in the super-region of Southeast Asia, East Asia and Oceania, with 1.8 million total deaths.

The high health costs of climate change in Canada, focused on heat stress and air pollution

The Health Costs of Climate Change was released in June by the Institute for Climate Choices, the second in their series on the costs of climate change. This report attempts to quantify how air quality, increased cases of Lyme disease, and heat will impact people’s health, using two different GHG scenarios until the year 2100. The report also discusses broader issues such as the socio-economic factors which determine unequal health results, mental health impacts, impacts on Indigenous culture and food security, and the impacts on health infrastructure.  Results show that Lyme disease will be the least costly of the projected impacts, but air pollution and heat threats will increase dramatically – even under the low-emissions scenario, heat-related hospitalization rates will increase by 21 per cent by mid-century and will double by the end of the century. The labour productivity impact of higher temperatures is projected as “a loss of 128 million work hours annually by the end of century—the equivalent of 62,000 full-time equivalent workers, at a cost of almost $15 billion.”  Unlike most reports which focus on the impacts of heat on outdoor workers only, the report acknowledges the impact on indoor space too, and offers some analysis and cost analysis of the installation of green roofs and shading on manufacturing facilities. It concludes with recommendations for government policy, and includes a 10-page bibliography of Canadian health research.  “Climate change is set to cost Canada’s health system billions”  (The National Observer, June 3) summarizes the report.   

Tidal wave of climate litigation: cases and trends examined in new report

On January 26  the United Nations Environment Programme and the Sabin Center at Columbia University published Global Climate Litigation Report: 2020 Status Review , revealing a “growing tidal wave of climate cases” which show “how climate litigation is compelling governments and corporate actors to purse more ambitious climate change mitigation and adaptation goals.”

The report states that as of July 1, 2020, at least 1,550 climate change cases have been filed in 38 countries around the world – nearly double the number of cases in the previous report published in 2017, which had documented 884 cases brought in 24 countries. The report summarizes key trends in cases – “ ongoing and increasing numbers of cases relying on fundamental and human rights enshrined in international law and national constitutions to compel climate action; challenging domestic enforcement (and non-enforcement) of climate-related laws and policies; seeking to keep fossil fuels in the ground; claiming corporate liability and responsibility for climate harms; addressing failures to adapt and the impacts of adaptation; and advocating for greater climate disclosures and an end to corporate greenwashing on the subject of climate change and the energy transition.” The report also notes emerging issues in the next five years, including increased attention to attribution studies,  and highlights significant and precedent-setting  cases throughout.

Global Climate Litigation Report: 2020 Status Review is current to July 1, 2020. Since then, at least three more important cases have been decided: 1.  in December 2020, a U.K. coroner ruled that “Air pollution a cause in girl’s death, coroner rules in landmark case” (The Guardian, January 2021); 2. an Appeals court in France overturned an expulsion order against an asthmatic man because he would face “a worsening of his respiratory pathology due to air pollution” in Bangladesh, his home country (the significance described in The Guardian in “Air pollution will lead to mass migration, say experts after landmark ruling” , with more details here). And 3. on January 29, 2021, a Dutch Appeals court brought an end to a case begun in 2008, when it upheld a decision against Royal Dutch Shell petroleum, finding it responsible for multiple oil spills and leaks which poisoned farmland in the Niger Delta. A Reuters report  quotes Friends of the Earth, saying “the ruling exceeded all expectations and marked the first time a multinational had been instructed by a Dutch court to uphold a duty of care for foreign operations.” The case is also summarized in “After 13 years, Justice: Dutch court orders Shell to pay for harm done to Nigerian farmers and in Deutsche Welle in “Dutch Court rules Shell liable for Niger Delta oil spills.

And in the United States, a potentially landmark case of climate liability is underway as of January 2021. According to a summary at NPR the city of Baltimore is presenting its claim for the cost of climate-related damages against more than a dozen major oil and gas companies including BP, ExxonMobil and Shell. According to NPR: “The Supreme Court will announce its decision later this year on the narrow question of whether the Baltimore case should be considered in state or federal court. If the justices decide in favor of the companies and the case proceeds in federal court, it’s possible that the lawsuit will be eventually dismissed without a trial. However, if the justices decide in favor of Baltimore, it is likely that the case will proceed in Maryland state court, which could require the companies in the case to turn over vast troves of documents about their businesses and marketing practices over the decades.” A multitude of legal documents have been compiled since the case began in 2018, and are available at the Sabin Center for Climate Change Law here.

2020 Lancet Countdown report on Health and Climate Change finds Canadians most at risk from extreme heat and air pollution

The Lancet Countdown Report on Health and Climate Change has been a landmark report since its first edition in 2015 (earlier reports are here ) .Compiled by an international team from more than 35 institutions including the World Health Organization and the World Bank, it documents the health impacts of climate change, and discusses the health and economic implications of climate policies. The global  2020 Countdown Report was released on December 2. Along with troubling statistics comes one core message:

“The COVID-19 pandemic and climate change represent converging crises. Wildfires and tropical storms in 2020 have tragically shown us that we don’t have the luxury of tackling one crisis alone. At the same time, climate change and infectious disease share common drivers. Responding to climate change today will bring about cleaner skies, healthier diets, and safer places to live–as well as reduce the risk factors of future infectious diseases.”

The Countdown project produces country-specific reports , with the Canada Briefing written by Drs. Claudel Pétrin-Desrosiers and Finola Hackett, and endorsed by the Canadian Medical Association.  The Canadian briefing presents updated information on two major issues: extreme heat and air pollution. Some highlights:

  • a record 2,700 heat-related deaths occurred among people over the age of 65 in Canada in 2018;
  • there were 7,200 premature deaths related to fine particulate air pollution from human-caused sources in Canada in 2018;
  • the work hours lost due to exposure to extreme heat was 81% higher in 2015-2019 than in 1990-1994 in Canada, with an average of 7.1 million extra work hours lost per year.

Although previous Canadian reports have called for carbon pricing, the 2020 report offers six recommendations which prioritize retrofitting and energy efficiency policies, along with funding for low-emissions transportation and active transportation.  The report also calls for: “…a recovery from COVID-19 that is aligned with a just transition to a carbon-neutral society, considering health and equity impacts of all proposed policies to address the climate and COVID-19 dual crises, directly including and prioritizing the disproportionately affected, including Indigenous peoples, older persons, women, racialized people, and those with low income.”

Courtney Howard, past president  of the Canadian Association of Physicians for the Environment writes “COVID-19 recovery is an opportunity to tackle worsening climate crisis: New report”  (The Conversation, Dec. 3).  The Canadian Medical Association announcement of the report is here ; and the CMA also released a recent survey  of its members, showing that 95% of respondents recognized the impacts of climate change, and 89% felt that  health professionals have a responsibility to bring the health effects of climate change to the attention of policy-makers . The World Health Organization sponsored the survey as part of a global initiative –  the Canadian results will be included  in a global WHO report scheduled for release in January 2021.

Job creation is a co-benefit of reducing air pollution

1.5 million jobs in Canada in 2050 by meeting Net-Zero emissions targets

The Healthy Recovery Plan released by the Canadian Association of Physicians for the Environment (CAPE) on July 14 quantifies the potential health benefits related to improved air quality in Canada, makes detailed recommendations for green recovery stimulus, and estimates the  job creation benefits of those recommendations: notably decarbonization of electricity generation and public transit by 2040, and decarbonization of vehicles, residential and commercial buildings, and healthcare by 2050.  

The report presents original research, conducted for CAPE by Navius Research, which simulated the health benefits of climate actions that meet Canada’s emissions reduction targets, using Health Canada’s own Air Quality Benefits Assessment Tool. Navius estimates that by meeting its climate targets, Canada will save 112,000 lives between 2030 and 2050 due to air quality improvements alone. Navius Research also simulated key economic impacts of an emissions scenario in line with Canada’s climate target of net-zero emissions by 2050, and found that clean jobs could increase from 210,000 full-time equivalent positions in 2020 to 1.5 million in 2050.

U.K. Employers group calls for air pollution reduction as part of a green recovery

Polluted air in the U.K.  is responsible for the loss of 3 million working days each year, according to research commissioned by the British Clean Air Fund, and conducted by CBI Economics, part of the British employers’ group, the Confederation of British Industry (CBI) . Breathing life into the UK Economy quantifies the economic benefits if the UK were to meet air quality guidelines recommended by the World Health Organization (WHO). The report estimates that improved health of workers would translate into a £1 billion gain for the economy in the first year, a £600 million gain to businesses from reduced absenteeism, and a £900 million increase in wages each year. The report also includes estimates for individual urban areas (London, Manchester, Bristol, and Birmingham).  Air pollution is a high profile issue in British politics, with U.K. unions campaigning since 2017 for a legal obligation on employers to address air pollution from their activities.  The Clean Air Fund press release which accompanied the release of the report quotes the CBI position: “Not only is there a clear moral responsibility to address air pollution and the impact it has on human health and the environment, there’s also a striking economic rationale. That is why the CBI has been absolutely clear that a focus on green recovery should be central to our COVID-19 response…. From mass energy efficiency programmes to building new sustainable transport infrastructure, the green economy offers incredible opportunities for the UK. Improving air quality should be a key part of the UK’s journey to net zero.” 

Dangers of air pollution for road workers increases in summer

Asphalt roads make city air pollution worse in summer, study finds “ appeared in The Guardian (Sept. 2), summarizing U.S. research that found a 300% increase in emissions of secondary organic aerosols (SOA) when asphalt was exposed to hot summer conditions. The full academic article appeared in Science Advances in September.  Dr Gary Fuller, air quality expert at Imperial College London is quoted in The Guardian: “We have historically thought of traffic pollution as coming from vehicle exhausts. This has been the focus of policy and new vehicles have to be fitted with exhaust clean-up technologies. ..With heavier and heavier vehicles, the combined total of particle pollution from road surface, brake and tyre wear is now greater than the particle emissions from vehicle exhaust but there are no policies to control this.” Also quoted, Drew Gentner of Yale University and one of the study’s co-authors : “Hotter, sunnier conditions will lead to more emissions. Additionally, in many locations, asphalt is predominantly applied during the warmer months of the year.” Bad news and added danger for construction workers.

A more general discussion of the extent and impacts of pollution was published by  the European Environment Agency (EEA) on September 8. Healthy environment, healthy lives: how the environment influences health and well-being in Europe reports that environmental pollution caused more than 400,000 premature deaths in the EU per year, and 13% of deaths in Europe were the result of environmental pollution, with air pollution the leading cause.  

Blue skies from locked-down economies are fleeting – we still need strong policies to reduce carbon emissions

A statement from the World Meteorological Organization (WMO) on Earth Day estimates that the pandemic will result in a six per cent drop in carbon emissions in 2020 , but warned “COVID-19 may result in a temporary reduction in greenhouse gas emissions, but it is not a substitute for sustained climate action”.  The full WMO Statement on Global Climate Change continues …. “We need to show the same determination and unity against climate change as against COVID-19. We need to act together in the interests of the health and welfare of humanity not just for the coming weeks and months, but for many generations ahead.”

Scientists are speaking out against the “good news” approach of highlighting clear skies as a silver lining in the Covid crisis. Kate Marvel, a climate scientist at the NASA Goddard Institute for Space Studies and Columbia University, writes “I am a mad scientist” , calling for bolder climate change action, and stating  :

“I’m angry at the very idea that there might be a silver lining in all this. There is not. Carbon dioxide is so long-lived in the atmosphere that a small decrease in emissions will not register against the overwhelming increase since the start of the Industrial Revolution. All this suffering will not make the planet any cooler. If the air quality is better now, if fewer people die from breathing in pollution, this is not a welcome development so much as an indictment of the way things were before. “

U.K. financial consultants MSCI express similar thoughts from an economic viewpoint in “Will coronavirus reduce emissions long term? .  “This modeled decline in 2020 emissions does not necessarily indicate a structural change to our current world economy. The estimated emission levels are still comparable to those observed over the past five years, and the economy could readily rebound, returning emissions to prior levels. China already increased its industrial output when their quarantine began to slowly lift. Once Europe and the U.S. lift lockdowns and reopen borders, travel, commuting and economic output could return to “normal” levels. Thus, the projected decrease in global emissions could be short-lived. If so, the risk climate change poses to countries, companies and investors has not dissipated. A much more visible and immediate crisis has simply overshadowed it.”

Researchers from the Stockholm Environment Institute are interviewed in “COVID-19 pandemic raises new questions about the health impacts of air pollution”  and explain how  encouraging pictures of blue skies do not reflect the complexities of air pollution. The article, importantly, also seeks to counter the mis-impression that reduced economic activity is necessary to reduce air pollution, by pointing to the more important policy measures in many countries, including Canada, which have been improved air quality and human health without compromising economic growth.

The toll of Australia’s Black Summer of bushfires

Australia’s Summer of Crisis  was published by the Climate Council of Australia in March, describing the economic and climate change impacts of the bushfires of 2019/20. Although the bushfires were widespread, the report focuses on the two most severely affected areas of the country:  New South Wales and the Australian Capital Territory. It estimates that there was a 10-20 percent drop in international visitors, so that the tourism sector alone will lose at least $4.5 billion.  Bushfire-related insurance claims in New South Wales, Queensland, South Australia and Victoria totalled an estimated value of $1.9 billion.  The report also estimates the unprecedented climate impacts – between 650 million and 1.2 billion tonnes of carbon dioxide spewed into the atmosphere ( Australia’s annual emissions are around 531 million tonnes). The report states that the hot dry conditions which fuelled the fires will only worsen, and calls urgently for an end to fossil fuel production and export, and a plan to reduce Greenhouse Gas Emissions to net zero.

Health impacts

Unprecedented smoke‐related health burden associated with the 2019–20 bushfires in eastern Australia”, published in the Medical Journal of Australia (March 12) estimated that bushfire smoke was responsible for more deaths than the fires, and extraordinary health impacts. The researchers estimate there were  417 excess deaths, 1124 hospitalisations for cardiovascular problems and 2027 for respiratory problems, and 1305 presentations to emergency departments with asthma.  The article is summarized by The Guardian here  , which also reports that the authors have obtained funding for follow-up studies through the Centre for Air Pollution, Energy and Health Research (CAR), funded by Australia’s National Health and Medical Research Council .  The CAR website offers fact sheets and research summaries about bushfire impacts.


30% of Canadians exposed to air pollution from road traffic – with SUV’s and diesel trucks the top polluters

The scientific journal Nature underscored the health dangers of air pollution in an April 2019 editorial titled, “Stop denying the risks of air pollution”, which stating that exposure to outdoor air pollution accounts for 4.2 million deaths globally each year, according to the World Health Organization.   Although we face nothing like the tragic current situation in Delhi India , Canadians should  not be complacent. A two-year study into traffic-related pollutant concentrations found that nearly 30 per cent of Canadians live near major roadways and thus are exposed to a “soup” of pollutants in their daily lives.

air pollution 2019 coverScientists measured pollutants at six monitoring stations near Toronto, including Highway 401, and Vancouver  between 2015 – 2017, and published their latest results in October, in Near-road air pollution Pilot Study . Findings include:

Highly polluting diesel trucks are making a disproportionate contribution and they represent the major source of key pollutants such as nitrogen oxides and black carbon. Data for these pollutants indicate that excessive exposure to diesel exhaust can occur near roads with a significant proportion of truck traffic.

Canada’s cold winters can increase concentrations. Ultrafine particle concentrations, for example, are higher in winter. Nitrogen oxide concentrations are higher on cold winter days, suggesting that the emission control systems for diesel vehicles may not perform well at low temperatures.

… non-tailpipe emissions of particles from brakes and tires have been rising in Toronto since 2012 and now exceed primary emissions through tailpipes. The cause is attributed to the growing popularity of SUVs and pickup trucks, which cause more tire and brake wear because they’re heavier.


Many of  the recommendations of the pollution study relate to strategies for continued scientific monitoring of transport-related pollution, but the report also recommends:

“Exposure to traffic-related air pollutants should be reduced where people live, work and play. Strategies should be taken to shape communities so that residents’ exposure to traffic-related air pollution is reduced. These strategies can contribute to existing plans for vibrant and compact communities. For example, a mix of land uses (e.g., commercial, retail, etc.) can be promoted within higher exposure areas; pedestrian and cycling infrastructure can be moved away from high exposure areas; and walkability, transit service quality and access, and parking management can be improved. Indoor exposure can be reduced by improving building design and operation, including ventilation and filtration systems.”

The research was conducted over a two-year period by The Southern Ontario Centre for Atmospheric Aerosol Research at the University of Toronto (SOCAAR), in collaboration with Environment and Climate Change Canada, the Ontario Ministry of the Environment, and Metro Vancouver.  The lead author is Professor Greg Evans of the University of Toronto.  The full report is available in English only; a  Summary report is available in English or French from this link .

Although the results have been published previously in academic journals, the study was widely covered in the media – for example,  in the Toronto Globe and Mail , and a thorough summary by the CBC .

The growing threat of SUV’s and Diesel trucks :

An October blog  by the International Energy Agency highlighted “a dramatic shift” to SUV’s: “…there are now over 200 million SUVs around the world, up from about 35 million in 2010, accounting for 60% of the increase in the global car fleet since 2010. Around 40% of annual car sales today are SUVs, compared with less than 20% a decade ago.” The full analysis underlying the blog will be published in the forthcoming World Energy Outlook 2019 in mid-November 2019.

In Canada, heavy duty trucks form the majority of the freight fleet, and freight transport accounts for 10.5% of our greenhouse gas emissions.  The Pembina Institute published  Fuel savings and emissions reductions in heavy-duty trucking in May 2019, to provide a roadmap to the technological solutions already available to reduce trucking emissions.  On October 16, the Capital Plan for Clean Prosperity published recommendations for the transportation sector:  How greening transport can boost economy and curb GHGs These policy recommendations deal with all personal transportation, public transit,  and freight transportation; regarding freight, the Capital Plan recommends that a federal grant system be established to allow for 50% of new freight trucks to be zero emissions vehicles, at an estimated total cost of $14.4B .  Estimated benefits for the freight industry include emissions reductions,  savings of $53.8 billion in fuel and maintenance costs, and  24,800 to 50,000 new jobs in the freight industry alone.

The Lancet measures the impact of climate change on public health, productivity and more


The Lancet Countdown: Tracking Progress on Health and Climate Change is a global, interdisciplinary research collaboration which has published an annual review since 2016.   The Lancet Countdown’s 2017 Report  tracks 40 indicators across five areas, and concludes that the human symptoms of climate change are unequivocal and potentially irreversible. Of particular interest, Indicator 1.3 states that  “global physical labour capacity in populations exposed to temperature change has decreased by around 5.3% between 2000 and 2016.”  Other alarming statistics:  between 2000 and 2016, the number of vulnerable people exposed to heatwave events has increased by around 125 million; without further action against climate change, over 1 billion people may be at risk of become climate change migrants by the end of the century.  The full report is available here (registration required, free).

In addition to the global report,  the Lancet Countdown produces country-specific reports;  the Briefing for Canadian Policy-makers was  written in partnership with the Canadian Public Health Association.  It  makes several  recommendations for Canadian action, including • Phase out coal-powered electricity in Canada by 2030 or sooner, with a minimum of two thirds of the power replaced by non-emitting sources, and any gap made up by lowest-emitting natural gas technology. Track and cost the health benefits of the transition in Canada and globally; • Develop a National Active Transport Strategy for Canada to coordinate improvements to walking, cycling and transit environments. This should receive priority funding, with healthcare cost savings calculated in order to demonstrate the cost offset of the investments. • Enhance support for telecommuting and telehealth options. Within health systems, gather and analyze data on kilometers, greenhouse gas emissions, air pollution and costs saved by telehealth in order to help drive systems change. • Increase funding for research into the local health impacts of resource extraction, with a focus on impacts on Indigenous populations.• Integrate Health Impact Assessments as a core component of the federal Environmental Assessment process.Lancet_twitter_card_5

Pollution cost Canada $2 billion in Lost Labour Output alone

The June 2017 report, Costs of Pollution in Canada: Measuring the impacts on families, businesses and governments reviews and synthesizes existing studies to produce the most comprehensive assessment of pollution and its costs  in Canada to date. Some quick facts: the cost of climate change-related heat waves in Canada is estimated to have been $1.6 billion in 2015; Smog alone cost Canadians $36 billion in 2015. But the report also provides detailed estimates, organized in three categories: 1.  Direct Welfare Costs: (Harm to health and well-being such as  lower enjoyment of life, sickness and premature death); 2.  Direct Income Costs – (Direct out of pocket expenses for families (e.g. medications for asthma), businesses (e.g. increased maintenance costs for buildings) and governments (remediation of polluted sites); and 3. Wealth impacts.

Direct Welfare Costs of pollution, the most studied and understood,  are estimated as at least $39 billion in 2015, or about $4,300 for a family of four.  The Direct Income Costs   that could be measured amounted to $3.3 billion in 2015, but the study cautions that this many important costs could not be measured, and full impacts on income were likely in the tens of billions of dollars.  In this category, the study estimates  Lost Labour Outputs, using a metric derived from the 2016  OECD study,  The  Economic Consequences of Outdoor Air Pollution.  The OECD estimates outdoor air pollution to cost 0.1% of national GDP, which, when applied to Canada’s  2015 GDP of approximately  $1,986 billion, implies a costs of about $2 billion in lost labour output alone. And finally, Wealth impacts, or costs on value of assets , are said to be the least understood of pollution costs, about which, “We simply do not know how much pollution costs us in terms of lost wealth”.

Costs of Pollution in Canada: Measuring the impacts on families, businesses and governments was prepared by the International Institute for Sustainable Development (IISD), with funding from the Ivey Foundation; the full report is available in English- only. Summaries are in English  and French.Short  videos were derived in cooperation with the Conference Board of Canada to focus on key topics:  e.g. extreme weather, contaminated sites, and smog .

A closer look at electric vehicle growth: impact on pollution, and labour conditions in the mines supplying raw materials

solar-power-1020194_1920The summer started with several “good news” stories about the surge of electric vehicles, such as “Starting in 2019, Volvo will use electricity to power every new model” from the Washington Post (July 5) , quoting Volvo’s CEO :  “This announcement marks the end of the solely combustion engine-powered car.”  Bloomberg Business Week, summarizing the findings of its latest New Energy forecast,  stated on July 7, “in just eight years, electric cars will be as cheap as gasoline vehicles, pushing the global fleet to 530 million vehicles by 2040″, and “Electric cars will outsell fossil-fuel powered vehicles within two decades as battery prices plunge, turning the global auto industry upside down and signaling economic turmoil for oil-exporting countries” .  On July 6,  France announced   it would end the sale of gas and diesel cars by 2040 ,  and on July 26 the U.K. released its Clean Air Plan, which included  a ban on the sale of new diesel and gas cars after 2040, with only electric vehicles available after that.

Response to the U.K. announcement is mixed.  In “Electric cars are not the solution to air pollution” Professor Frank Kelly, a professor of environmental health at King’s College London and chair of the government’s  Committee on the Medical Effects of Air Pollutants states that “The government’s plan does not go nearly far enough,” “Our cities need fewer cars, not just cleaner cars.”  In his role as a member of  the Centre for London’s commission on the future of the capital’s roads and streets  ,    Professor Kelly provides more detail about the problem of particle pollution and states:  “London should lead in showing electric cars will not tackle air pollution”  in The Guardian (August 4).  His conclusion: “The safe and efficient movement of people around the city can only be achieved through a clean and expanded mass transit system served by buses, overground trains and the underground system – and as much active transport in the form of walking and cycling as is feasibly possible.”

Others are raising issues about electric vehicles on other grounds, specifically the environmental costs  and labour conditions of producing the lithium ion batteries that power them.  These are not new concerns:  Carla Lipsig Mumme and Caleb Goods raised the flag in June 2015 with “The battery revolution is exciting, but remember they pollute too”   in The Conversation.   In January 2016, Amnesty International published a detailed documentation of the hazardous working conditions and the use of child labour in cobalt mining in the Democratic Republic of the Congo in  This is what we die for: Human rights abuses in the Democratic Republic of the Congo power the global trade in cobalt  . (Cobalt is also used in mobile phones, laptop computers, and other portable electronic devices). The report  is available in English, French and Chinese from this link .

More recently,  “Politically charged: do you know where your batteries come from? ” appeared in The Conversation (July 26),   providing an overview of the geography , politics, and environmental impact of  lithium-ion battery raw materials. Briefly, the current major producers of lithium are Australia, Chile, Argentina and China, with Australia and Chile accounting for about 75% of the total. The main environmental concern, especially in Chile, is that the extraction can impact water supply in desert areas.  The article also looks at supply chain issues and states : “With almost half of the world’s cobalt ore reserves concentrated in Democratic Republic of Congo for the foreseeable future, and with a large proportion of refining capacity located in China, the supply chain could be more vulnerable.”  Not to mention the vulnerability of the miners Amnesty International has documented.

A  Canadian viewpoint on  the issue of supply:   “Clean Energy Spurs Lithium Rush, Demands Response to ‘Dirty Mining’” in the  Energy Mix (August 8). In the article, Financial Post columnist Peter Tertzakian states: “ it takes the equivalent of 15,000 cell phone batteries to make one battery for an electric car,” and “ramping up raw material inputs to build millions of car batteries a year fills the back of the envelope with scalability issues.” These supply issues may lead to a growth of “dirty mining” practices.  Will Canada be affected by the push for clean energy raw materials?  We do not currently produce lithium, although the article states that  engineers are trying to isolate it from tar sand/oil sand waste. We are a minor producer of other battery components,  graphite and cobalt, and the 3rd largest  producer of  nickel in the world.  According to Bloomberg News in August, the growth of electric vehicles will drive a doubling of demand for nickel by 2050. However, Bloomberg reports that  mining giant  BHP Bilton will invest in Australia to make it the world’s largest producer of nickel for electric vehicle batteries.

A final troubling issue with electric vehicles: disposal.  “The rise of electric cars could leave us with a big battery waste problem ”   according to The Guardian (August 10) , which cites the International Energy Agency estimates of  140m electric cars globally by 2030, resulting in a possible  11 million tonnes of spent lithium-ion batteries in need of recycling.  Two solutions are profiled in the article: recycling and reuse. The recycling profile features the CEO of  Canadian battery recycling start-up company, Li-Cycle, which is pioneering a  wet chemistry process which would  retrieve all of the important metals from batteries. The  proponents of the re-use solution include Aceleron and carmaker Nissan, which has patented a process for re-use. The article states that  car batteries can still have up to 70% of their capacity when they stop being good enough to power electric vehicles, so that they can be broken down, tested and re-packaged for functions such as home energy storage.




Union calls for a legal responsibility on employers to address a crisis in U.K. air pollution

BWTUC logoThe Battersea and Wandsworth Trades Union Council (BWTUC) is the Southwest London arm of the Trades Union Congress and a founding supporter of the Greener Jobs Alliance. The BWTUC has undertaken a campaign against toxic air, and argues that employers are the root cause of diesel emissions –  from their transport fleets as well as the individual  journeys to and from work made by workers.  As part of its campaign against what it calls the “number one public health issue”, BWTUC will help local unions to carry out monitoring of pollution levels where they work, and is also producing online training modules which will be available at the Greener Jobs Alliance website after a May 27 launch.  Finally, it is advocating for a Clean Air Act, as stated in the  Greener Jobs Alliance Top 10 Election Demands  : #10: “ Introduce a Clean Air Act to tackle air pollution once and for all. Place a clear legal responsibility on employers and businesses to address air quality and develop a network of low emission zones in pollution hot spots.”

The U.K. government has addressed the issue of roadside air pollution in Improving air quality in the UK: tackling nitrogen dioxide in our towns and cities: Draft UK Air Quality Plan for tackling nitrogen dioxide  (May 2017).  Unlike the BWTUC, the government clearly sees pollution as an individual, not employer, responsibility.  “The UK Government is clear that any action to improve air quality must not be done at the expense of local businesses and residents. Therefore local authorities must work closely with local people to create an approach which works for them. Everyone has a role to play in helping to address NOx by considering how they can reduce emissions through their day-to-day activities, for example by choosing cleaner vehicles.”  The government does propose incentives for low carbon fuel vehicle fleets, and for clean busses for commuting, but the plan is controversial and inadequate – see “UK’s new air pollution plan dismissed as ‘weak’ and ‘woefully inadequate‘” and  “Air pollution plan: sacrificing the nation’s health to save an election campaign“, both of which appeared in The Guardian on May 5.

double decker busAccording  to a BWTUC press release , the people of Battersea/Wandsworth have a lot at stake: “In 2016 Putney High St had the dubious distinction of being the most polluted road in the whole of Europe.  By law hourly levels of Nitrogen Dioxide must not exceed 200 micrograms per cubic metre more than 18 times in one year. In fact, the hourly limit was exceeded over 1,200 times in 2016. In January 2017 the standard was breached 11 times in one day.” …. “In April, the Wandsworth Guardian quoted a report that showed 29 schools in the borough located in areas exceeding the safe legal limit.”

Health Impacts of Cap and Trade policies on California’s disadvantaged communities

Acting on a December 2016 Executive Order of Governor Gerry Brown, the California Office of Environmental Health Hazard Assessment released the first in a series of reports which will examine the impact of the state’s climate change programs on communities designated as “disadvantaged”.  The February report,  Tracking and Evaluation of Benefits and Impacts of Greenhouse Gas Limits in Disadvantaged Communities: Initial Report   measuring the effects of  the Air Resources Board’s Cap-and-Trade Program, which regulates greenhouse gas emissions from industrial facilities and other sources.  The report is largely based on 2014 emissions data, and warns that “limited data does not yet allow for comprehensive analysis of the impacts of Cap-and-Trade on disadvantaged communities”.   Initial findings however, are that  major industrial facilities are disproportionately located in disadvantaged communities;  there is a moderate correlation between GHG and other air pollutants, with refineries showing the strongest correlation.   California maintains  a planning and enforcement tool,  CalEnviroScreen, the “ first comprehensive, statewide environmental health screening tool” in the U.S.  In late January, California Air Resources Board   announced the appointment of its first Assistant Executive Officer for Environmental Justice, with a mandate to ensure that environmental justice and tribal concerns are considered in air pollution policy-making and decision- making.

Canadian government announces a phase-out of “traditional” coal-fired electricity by 2030

On November 21, the federal Environment Minister announced  that the four remaining provinces with coal-fired electricity  (Alberta, Saskatchewan, New Brunswick, and Nova Scotia) must  speed up the their emissions reduction targets. All traditional coal-fired units (i.e. those without carbon capture and storage)  will be required to meet a performance standard of 420 tonnes of carbon dioxide per gigawatt hour by no later than 2030, and performance standards must be developed  for new units to ensure they are built using efficient technology.  Details are set out in a Backgrounder  .  To allow for flexibility, Equivalency Agreements can be negotiated under the Canadian Environmental Protection Act , and both Nova Scotia and Saskatchewan are pursuing such agreements.  Nova Scotia, which announced  on November 21 that  it would  implement a cap and trade system which would  meet or exceed the federal emissions reduction target , will be allowed to continue to use coal in high-demand winter months even after 2030, (with no  specific date set yet for full compliance) .  Saskatchewan, which relies heavily on carbon capture and sequestration technology to meet its recent emissions reduction plan, is “displeased”  about the coal phase-out plan, according to a CBC report .  Alberta has already announced its own plans   for a coal phase-out by 2030, promising  support for workers and communities.  See the “Liberals present plan to phase out coal-powered electricity by 2030” CBC (Nov. 21) for a good overview.

 What does this mean for coal workers?  Currently, coal-fired power  generated at 35 plants represents over 70% of emissions in Canada’s electricity sector, but provides  only 11% of our  electricity.  The coal industry employs approximately 42,000 direct and indirect workers.   In “Canada’s rejection of coal will clear the air but impact workers and power bills” , the CBC (Nov. 22) examines the likely higher  electricity bills in store for consumers, and  the likely job losses.  The CBC article quotes Warren Mabee, a researcher with the Adapting Canadian Work and Workplaces to Climate Change project and the associate director of the Queen’s Institute for Energy and Environmental Policy: he states that many workers in coal mines will be laid off  “while others will shift to extracting metallurgical coal, which is used in the steel-making process.”  It is important to note that the government press release explicitly promises:“ The Government of Canada will work with provinces and labour organizations to ensure workers affected by the accelerated phase-out of traditional coal power are involved in a successful transition to the low-carbon economy of the future.”

Much of the government’s motivation for its initiative comes down to the health benefits of removing pollutants of coal-fired electricity – carbon dioxide, sulphur dioxide, nitrous oxide, mercury and other heavy metals .  The Pembina Institute, along with the Canadian Association of Physicians for the Environment, Canadian Public Health Association   and others, released   Out with the coal, In with the new: National benefits of an accelerated phase-out of coal-fired power  on November 21.  The report estimates that a  national coal phase-out by 2030 would prevent  1,008 premature deaths, 871 ER visits, and health outcomes valued at nearly $5 billion (including health and lower productivity costs) between 2015 and 2035.  The Pembina Institute reacted to the government announcement, calling it “timely” and “necessary .  Clean Energy Canada responded with  Quitting coal will drive clean growth and cut pollution.   BlueGreen Canada, which includes the United Steelworkers union, recently published the  Job Growth in Clean Energy report, which recognizes the world-wide decline of the coal industry, and states that, “if properly supported now, Alberta’s renewable energy sector will create enough jobs to absorb the coal labour force”.

Canada promises action to implement the Kigali agreement on HFC’s

The agreement reached  in Kigali, Rwanda  on October 15 2016, to regulate the use of the hydrochlorofluorocarbons ( HFC’s)  in air conditioners and refrigerators,  is expected to lead to the reduction of the equivalent of 70 billion tons of carbon dioxide from the atmosphere, and “is the single largest contribution the world has made towards keeping  the global temperature rise ‘well below’ 2 degrees Celsius”, according to the UNEP Press release about the agreement.   The 197 countries which had previously been party to the Montreal Protocol reached a compromise, under which developed countries will start to phase down HFC’s by 2019.  The deadline for some developing countries to  freeze their HFC’s consumption levels is 2024, and some  of the world’s hottest countries (India, Pakistan, Iran, Saudi Arabia and Kuwait) will have the most lenient deadlines, to freeze HFC use by 2028 and reduce it to about 15 percent of 2025 levels by 2047.  Read the New York Times report here ,  or the National Observer report here  , and for background, an August NYT article, “How bad is your air conditioner for the planet?“.  For a legal perspective, see “Cutting HFC’s under the Montreal Protocol – A few thoughts” from the Legal Planet blog of UCLA Berkeley.

The Kigali agreement is  seen as a powerful positive symbol: “It is a clear statement by all world leaders that the green transformation started in Paris is irreversible and unstoppable.”  But though it is seen as a much stronger commitment than the Paris Agreement, it also  requires ratification by two-thirds of the parties to come into force, and may not be “unstoppable”.    According to Climate Central, ” American experts on international environmental law say ratifying the new HFC agreement would almost certainly require a two-thirds vote from the Senate”. In other words, even more is now riding on the U.S. election on November 8.   A Globe and Mail article on October 16  expanded on the brief government press release ,  quoting the Canadian Environment and Climate Change Minister, who pledged: “Ottawa will adopt regulations to reduce the use of the chemicals in the coming years. The government will provide rules and incentives for the destruction of existing HFCs.”

More proof that green buildings are better for workers

The health impact of  green workplaces was the subject of a new article,   The Impact of Working in a Green Certified Building on Cognitive Function and Health  , by researchers at the  Harvard T.H. Chan School of Public Health and SUNY Upstate Medical University. Researchers studied 109 workers at 10 buildings and found that employees who worked in certified green buildings had higher cognitive function scores, fewer sick building symptoms and higher sleep quality scores than those working in non-certified buildings.  The research was sponsored by United Technologies.  For an overview of ongoing research at the Harvard T.H. Chan School of Public Health , go to its Nature, Health and the Built Environment website . Other related information is available at the World Green Building Council’s “Better Places for People” website .

From a management point of view, an article in the Harvard Business Review, “Air Pollution making office workers less productive”  (September 29) reports on the effect of air pollution on call-center workers at Ctrip, China’s largest travel agency. The authors conclude that these office  workers are 5%–6% more productive when air pollution levels are rated as “good” (an Air Quality Index of 0–50) versus when they are rated as unhealthy (an Air Quality Index of 150–200). Productivity was measured by completed calls each day, length of breaks, and time logged in.

All this points to the importance of green building.  World Green Building Week  began on September 26, 2016 – preceded by an agreement amongst the national green building councils from 10 countries (including Canada)  to adopt zero net carbon certification programs by the end of 2017.  See the World Green Building Council press release for a description of the meetings, including the definition of “zero net carbon” (ZNC)  as advanced by the architectural network, Architecture 2030   .

Alberta keeps its options open with renewable energy targets and preliminary approvals for 3 oil sands projects

In addition to a commitment to phase out coal-fired power by 2030, on September 14,  the Government of Alberta announced a firm target to generate 30 per cent of its electricity from renewable sources such as wind, hydro and solar by 2030. The government press release  associates this target with a projection that “at least $10.5 billion in new investment will flow into the provincial economy by 2030. This will mean at least 7,200 new jobs for Albertans as projects are built.” The health benefits of shutting down coal plants are highlighted in Breathing in the benefits: How an accelerated coal phase-out can reduce health impacts and costs for Albertans, a joint report from the Pembina Institute, the Canadian Association of Physicians for the Environment, the Lung Association of Alberta and NWT, and the Asthma Society of Canada, released on September 14.

On September 19,  the government appointed a Task Force, to be chaired by Gordon Lambert,  to make recommendations on targeting investments in climate technology to help transition to a lower-carbon economy. Submissions are invited; a report will be submitted by the end of November, summarizing the findings of the engagement and providing recommendations for a provincial Climate Change Innovation and Technology Framework.  Also underway: an Energy Efficiency Advisory Panel   which was launched in June 2016 (see the Discussion Document here )  and an Oil Sands Advisory Group  .     But not all is renewable in Alberta:  on September 15, the government announced  early stage approval of 3 new oil sands projects, representing “ about $4 billion of potential investment into Alberta’s economy and about 95,000 barrels per day of production”.  The proposed developments will still undergo further environmental reviews and will fall under the oil sands 100 megatonne greenhouse gas emissions limit, announced with Alberta’s Climate Leadership Plan.

Air Pollution and Coal: A Public Health issue around the world

On May 18, the Canadian Association of Physicians for the Environment, along with the Canadian Public Health Association (CPHA), the Heart and Stroke Foundation of Canada, the Registered Nurses’ Association of Ontario (RNAO), the Canadian Lung Association, the Ontario Public Health Association (OPHA)  joined a global call   for the G7 nations to accelerate the transition away from coal­-fired electricity, to bring “ immediate and significant air pollution-­related health benefits and health care savings. A coal phase-­out also slows climate change, thereby reducing current and future illnesses and deaths from heat waves, droughts, malnutrition, flooding, air pollution and wildfires.” The Lung Association of America  recently ranked air pollution in U.S. cities and found that  Bakersfield, California, was the most polluted city for both short-term and year-round particle pollution, while Los Angeles-Long Beach was the worst for ozone pollution.  In the U.K., air pollution was cited as a “public health emergency” in a report published by a Select Committee of the Environment, Food and Rural Affairs Ministry  .  The World Health Organization (WHO)  ranked the world’s most polluted cities on May 12,  with four of the five worst cities in India. WHO surveyed 3,000 urban areas; the data shows only 2 per cent of cities in developing countries have air quality that meets WHO standards, compared to 44 per cent in developed countries. A WHO official also stated, “Probably some of the worst cities … are not included in our list, just because they are so bad that they do not even have a good system of monitoring of air quality, so it’s unfair to compare or give a rank.”
