Regional Emissions at a Glance
Carbon emissions increased in all six municipalities in 2021 as pandemic-related restrictions were lifted.
Transportation and buildings continue to be the two highest-emitting sectors for all six municipalities, with the notable exception of industry in the City of Hamilton (which is home to 55% of total industrial emissions in the GTHA). On a per capita basis, the City of Toronto continues to have the lowest emissions in the region, largely due to the higher use of alternative modes of transportation enabled by its density.
