Just launched: Carbon Emissions Inventory 2024

Measuring the Economic Health Benefits of Tailpipe Emission Standards

TAF submitted the following joint letter, with Canada’s leading health, air quality, and climate experts, to the Minister of Environment and Climate Change Canada, urging the Government of Canada to include the monetized health benefits of reduced air pollution in the regulatory analysis statement for the upcoming tailpipe emission standards. We ask that the regulatory […]

Ontario Electricity Emissions Factors and Guidelines

2025 Edition  TAF has published Ontario emissions factors since 2017 to support best practices in carbon quantification. Accurate emissions factors reveal how various interventions impact carbon reductions.  Planning for decarbonization and electrification is becoming more complex as more natural gas is used to generate electricity in Ontario. These numbers and guidelines allow practitioners to quantify […]

Scaling Heat Pump Retrofits through Aggregation and Bulk Procurement

April 2023. Greater Toronto and Hamilton Area. TAF commissioned Dunsky Energy + Climate Advisors to conduct a bulk procurement study to assess the barriers, opportunities, and trade-offs to scaling up heat pump retrofits through aggregation and bulk procurement. Key Takeaways Report findings suggest cost savings have some potential, but the best value of bulk purchasing […]

Fugitive Methane – New Guidelines

May 2022. Greater Toronto and Hamilton Area. Greenhouse gas emissions from natural gas combustion is responsible for 40% (20 megatonnes) of the carbon emissions in the Greater Toronto and Hamilton Area. However, this number does not account for the “fugitive” methane that leaks from extraction, fracking, pipelines, and distribution — the full life cycle of […]

2019-2020 Carbon Emissions Inventory for the GTHA

December 2021. Greater Toronto and Hamilton Area. The regional carbon emissions inventory for the Greater Toronto Hamilton Area includes two years of data (2019 and 2020) and provides the first look at emissions since the global pandemic. Consistent methodology, data sources, and time frames chart progress across the Region of Durham, Halton Region, City of […]

A Clearer View of Ontario’s Electricity Emissions: Updated Electricity Emissions Factors and Guidelines

THIS EDITION IS ARCHIVED. PLEASE SEE 2025 EDITION: Ontario Electricity Emissions Factors and Guidelines   Conventional methods to quantify electricity-related emissions can oversimplify and potentially distort the emissions impact of consumption, conservation, and the shift to renewables. An in-depth understanding of Ontario’s electricity emissions, and the use of appropriate emissions factors, is key to properly […]

Reality Check: Carbon Emissions Inventory for the GTHA

February 2021. Greater Toronto and Hamilton Area. Total carbon emissions in the GTHA increased 5.2% in 2018, reaching 55.5 Mt. This report is a stark reality check, showing that since the completion of the coal phase out, emissions are slowly increasing across all regions and nearly all sources. Our per capita natural gas emissions are […]

Comments on the Ontario government’s proposal to harmonize greenhouse gas reporting requirements

December 2019. Government of Ontario. The provincial government is proposing to harmonize greenhouse gas (GHG) reporting requirements with the federal regulatory requirements.  The amendments would mean that fuel suppliers and distributors would no longer be required to report GHG emissions from the transmission and distribution of natural gas, thus eliminating the ability to track fugitive […]
