Transportation and buildings remain the two highest-emitting sectors in nearly all regions. The City of Hamilton is the exception, where the sizeable steel manufacturing sector makes industry the highest emissions sector. Cement production concentrated in Durham and Peel and agriculture in Durham contribute considerably to their respective emissions.

Per capita emissions also increased across all six regions. The City of Toronto continues to have the lowest per capita emissions in the region, largely due to the higher use of transit, walking, and cycling, enabled by its density.
