Toronto passes new standards for new buildings, retrofits

55% of GHG emissions in the city of Toronto are attributed to homes and buildings ( 60% of that from residential buildings and 40% from commercial and institutional buildings).  On July 14, Toronto City Council took one more step to address those emissions, by approving new building policies. As described in the City’s press release, the policies include a “Net Zero Existing Buildings Strategy to decarbonize all existing residential, commercial and institutional buildings within the next 30 years; a Net Zero Carbon Plan to reduce emissions in City-owned buildings; and an update to the Toronto Green Standard to achieve net zero emissions in new development by 2030.”  

The Net Zero Existing Buildings Strategy: is expected to increase local building retrofit economic activity by 87 per cent over the next 30 years, and nearly double annual investment in existing buildings. It is also expected to create an additional 7,000 direct, full-time jobs in local construction, energy services and supportive work over 30 years. Further,

  • it will begin with voluntary emissions performance measures and targets, transitioning to mandatory requirements in 2025, at which time it will require annual emissions performance reporting and public disclosure;
  • Expand and enhance retrofit financing;
  • Support workforce development and training;
  • City Council will lead by example with a plan to retrofit all City-owned buildings to net zero emissions by 2040.   

The Green Standard for New Buildings: Emissions reductions in new buildings will be regulated by the newly approved the Toronto Green Standard Version 4.  The original Toronto Green Standard was introduced in 2010 and has been updated approximately every 4 years.  The latest Version 4 addresses requirements for “building energy and GHG reduction and electric vehicle parking, and introduces tracking of embodied emissions in building materials used in construction. It addresses resilience through enhanced green infrastructure to manage stormwater runoff, reduce urban heat island impacts and promote biodiversity, including extensive and higher performance green roofs, bioswales, rain gardens, native pollinator species plantings and a new requirement for ”green streets” (roads or streets that incorporate green infrastructure).”

Version 4 will apply to new development applications beginning on May 1, 2022.

According to Mayor John Tory: “Implementing this strategy will also be essential to public health and resilience in the face of a changing climate. Extreme heat is already causing an average of 120 premature deaths annually, and this number is expected to double by 2050 without strong action. Retrofit measures such as improving building envelopes and installing heat pumps greatly reduce exposure to extreme heat and will ensure Torontonians are safe during increasingly frequent and severe heat waves.”

Natural gas drives GHG emissions increase for Toronto region and Ontario

The Greater Toronto and Hamilton Area (GTHA) is home to 7.4 million people in six municipalities: the City of Toronto, City of Hamilton, Halton, Peel, York and Durham regions. According to a new report released by The Atmospheric Fund (TAF),  the region produces  44 per cent of  total carbon emissions in the province of Ontario.   Top level findings from the report, Reality Check: Carbon Emissions Inventory for the GTHA: “Total carbon emissions in the GTHA increased 5.2% in 2018, reaching 55.5 Mt. . …. showing that since the completion of the coal phase out, emissions are slowly increasing across all regions and nearly all sources.” The report zeroes in on each municipality, and also on sectors, showing that buildings (42.8%), transportation (34.3%), and industry (18.9%) are the most significant sources of emissions in the region.

The key take-away from the report:  “Natural gas is a fossil fuel (methane) and it is the most significant source of emissions in the GTHA and Ontario. In 2018 natural gas increased about 10.6%, or 2Mt CO2 eq. Achieving net zero by 2050 will require phasing out virtually all natural gas from both heating and power production.”  An associated blog , “Toronto has an embarrassing gas problem”  (Feb.18) states: “the City’s latest emissions inventory showed an increase of 68% from natural gas from 2017 to 2018, and plans are afoot to increase gas-fired electricity which will make emissions skyrocket by over 300%. …. Toronto cannot meet its 2030 climate goals or the council-approved TransformTO plan if Ontario’s electricity is increasingly generated with fossil gas.”

Based on this analysis, TAF makes policy recommendations for all three levels of government, calling for near zero emissions standards for new building, acceleration of deeper retrofits for existing buildings, and electrification of heating and transportation while decarbonizing electricity production.  Detailed recommendations regarding retrofitting measures are provided in TAF’s submission to the Federal Budget 2021, and summarized in “Four ways the government should boost the retrofit market” (Feb. 23).  At the municipal level,  TAF is supporting one City of Toronto Councillor’s motion which calls for the provincial government to phaseout all gas-fired electricity generation as soon as possible.  The City of Toronto deferred a vote on that motion, and voted in February on a budget which appears to downgrade the priority for climate initiatives.  “’We can’t afford to lose a year’: Worries abound over Toronto’s plan to reduce climate funding” (CBC, Feb. 18)  provides details.

New centre for Vancouver to spur urban climate action, especially building retrofits

Retrofitting is a priority for the newly-announced  Metro Vancouver Zero Emission Innovation Centre, to be administered through the Renewable Cities program at Simon Fraser University, Vancouver. According to the SFU press release of January 12, the Metro Vancouver Zero Emission Innovation Centre “will be seeded by a generous $21.7 million endowment from the federal government to identify, finance and scale up local climate solutions, such as building retrofits and electrification of transportation.”  The top priorities stated include “ “Identifying and initiating programmatic priorities, and integrating the Zero Emission Building Exchange to support building sector capacity building”.  For now, though, “the new centre’s work will start modestly. It is expected to grow steadily through partnership, programming investment, leveraging and innovative financing”.  The launch of the Centre is scheduled for  September 2021, after input is gathered “from a range of stakeholders, including local and provincial government, industry, non-profit organizations and the finance sector.”

The Vancouver Centre will be modelled on The Atmospheric Fund – originally known as the Toronto Atmospheric Fund when it was established in 1991 through the advocacy of then-Toronto City Councillors Jack Layton and Dan Leckie.  The Atmospheric Fund now serves Canada’s largest urban area, the Greater Toronto/Hamilton region of approximately 7 million people, and is part of  the  Low Carbon Cities Canada (LC3), a  partnership which also includes Vancouver, Calgary, Edmonton, Ottawa, Montreal and Halifax, as well as  the Federation of Canadian Municipalities.

In What does Canada’s new $15 billion plan mean for urban climate action?” (Dec. 15), The Atmospheric Fund reviews the federal government’s latest climate plan and discusses the two sectors most relevant to municipalities: buildings and transportation. The Atmospheric Fund states that its own priorities for 2021, include: “Partnering with housing providers to initiate deep retrofits in 3,000 housing units this year; Mobilizing $150 million in investment to leverage public funding and attract more capital into low-carbon activity;  Supporting municipalities to adopt green development standards for new buildings and performance standards for existing ones; Providing grants and investment capital to enable even more low-carbon activity like workforce development (clean jobs!) and EV charger installations; and Publishing new research on growing challenges like fugitive methane emissions and embodied carbon in new construction.” 

The governance of climate action in Toronto and Vancouver is summarized in a new article by three academics from the Universities of Waterloo and Toronto, “Strategies and Governance for Implementing Deep Decarbonization Plans at the Local Level, published in the latest issue of the journal Sustainability. It offers case studies of the best practices in climate action governance in Toronto and Vancouver, along with Bridgewater, Nova Scotia; Guelph, Ontario; Park City and New York City in the U.S., Lahti in Finland and Oslo in Norway. These cities range in size from 8,400 people to 9.6 million, but were chosen as “leading and ambitious” cities. The authors identify the importance of transnational networks in city decarbonization planning, and highlight their efforts “to expand their green economies and the capacity of their workforces to meet the future demand for skilled workers, especially in the buildings and construction sectors.”

And briefly:  A recent article in the New York Times also noted the importance of retrofitting: “New York’s real climate challenge: Fixing its aging buildings” (Dec. 29, New York Times). Stating that  “Nearly 70 percent of the city’s total carbon emissions come from buildings. A project to retrofit nine buildings with green technology is pioneering a new solution”.   The article describes the Casa Pasiva retrofitting project , one of a number of  RetrofitNY projects funded by the New York State Energy Research & Development Authority.

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.

City of Toronto declares climate emergency

Toronto smallCanada’s largest city,  Toronto, has unanimously adopted a climate emergency resolution on September 20, joining hundreds of other municipalities across Canada.  The city’s TransformTO Climate Action Plan, passed in 2017, had a target of cutting greenhouse gas emissions to 80 per cent below 1990 city levels by 2050.  The emergency resolution passed in September speeds up that timetable, with a new commitment to net zero emissions before 2050. (As of July 2019, the city was ahead of schedule with a 44% reduction below 1990 levels). The action was precipitated by a Call to Action , which includes a call for a “Just Economic Transition” and for “Equity and Inclusion” is described in a press release from the Toronto Environmental Alliance: “Forty-seven organizations call on Toronto City Council to declare a climate emergency” (Sept. 20). The Call to Action statement is here , the list of signatories is here , and it includes Toronto and York Region Labour Council, Toronto Community Benefits Network, Good Jobs for All, and BlueGreen Alliance.  A spokesperson for the Toronto Environmental Alliance states:  “The good news is that just about everything that Toronto needs to do will improve our quality of life. For example, properly insulating our buildings will make them more energy efficient and safe from extreme weather, and create jobs for people in the skilled trades…. If developed in a thoughtful and well-coordinated way, green workforce strategies can be inclusive and reduce poverty.”

The mayor’s  voluntary Green Ways Initiative is described in “Mayor John Tory enlists major institutions in emissions plan as Toronto declares ‘climate emergency’” in the Toronto Star.  Developers, hospitals, and universities are being urged to cut their energy consumption and emissions – and one of those volunteer entities, the University of Toronto, announced its Low Carbon Action Plan  on September 27.  The University of Toronto maintains 266 buildings on three campuses, and more than half of those are over 80 years old.  Other participants in the Green Ways Initiative include include Oxford Properties, Ryerson University, Toronto District School Board, Toronto Catholic District School Board, Toronto Community Housing, and the University Health Network.

gardiner toronto_trafficThe major criticism of the climate emergency resolution is outlined in “Toronto just declared a climate emergency, so why is it still fixing up the Gardiner?” at the CBC (Oct. 4), referring to the major highway artery across Toronto’s downtown.  Journalist  John Lorinc also pursues this in his article in Spacing (Sept. 30), which contends that the Gardiner Expressway redevelopment project accounts for 5% of the city’s entire $40.7 billion ten-year capital budget, which is money which could be better used to fund transit, such as the Queen’s Quay East LRT, or to finance the retrofitting of the city’s portfolio of buildings, including community housing.  To these criticisms, the mayor is quoted in the Toronto Star and the CBC with this statement: “The amount we’re spending on rebuilding a small part of the Gardiner Expressway pales in comparison to what we’re investing in public transit to get people out of their cars entirely”.
