Sector Emissions at a Glance
Buildings and transportation continue to be the largest emitting sectors in the GTHA
The building and transportation sectors continue to dominate emissions across the GTHA, representing over 81% of total emissions. Building emissions are driven by the use of natural gas for space and water heating as well as electricity, while transportation emissions are driven by gasoline and diesel use.
Overall, emissions have increased by over 4 million tonnes since 2021. Every sector saw an increase, with the building (up 2.1 MtCO2eq) and transportation (up 1.5 MtCO2eq) sectors having the biggest increases.
Buildings
Emissions are now at the highest levels since 2015. Continuing to delay reductions will compromise reaching climate targets.

Industry
Emissions have seen little change over the past 8 years, with cement and steel accounting for more than two-thirds of these emissions.

Waste
Little progress in reducing waste emissions highlights the ongoing importance of reducing waste overall and increasing landfill diversion.

Agriculture
Emissions remain largely unchanged over the past 8 years, driven mainly by the application of nitrogen fertilizers to agricultural lands.
