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.
