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
