Total emissions decreased marginally by 0.2%, making Peel the only region in the GTHA to see a small reduction. A 0.5% decrease in transportation emissions was offset by a 0.6% increase in building sector emissions. The industrial sector also contributed to the marginal decrease.

• Per capita emissions decreased significantly by 4.8% in 2024, reaching 7.1 tonnes of carbon per person. This is the largest decline across the GTHA.
• Excluding the industrial sector, per capita emissions were 6.2 tonnes of carbon per person, a 4% decrease from 2023.

• Building emissions in Peel increased slightly by 0.6%. This was despite a 4% drop in natural gas emissions, which was driven by a 6% decrease in the industrial sector and a 5% decrease in the residential sector.
• Electricity consumption increased by almost 2% and electricity emissions increased by 27%, driven largely by the higher carbon intensity of the provincial grid.
• Peel’s industrial emissions are estimated to have decreased by 3.3% for 2024, based on cement production and other manufacturing job growth. According to recently published facility reported data, industrial emissions in 2023 increased by 3.4%, largely due to emissions reported from G.E. Booth (Lakeview) Wastewater Treatment Facility.
• Peel saw a 31% increase in total electric vehicle registrations compared to 2023, with 19,026 EVs (up 28%) and 5,603 PHEVs (up 39%).
• In 2024, Brampton Transit had a 11% growth in ridership, while Mississauga Transit had a 4% growth.
• Scope 3 aviation emissions from Toronto Pearson Airport increased by 5%, rising from 7.2 MtCO₂eq in 2023 to 7.5 MtCO₂eq in 2024. However, these aviation emissions are not solely attributable to the Peel region, as Pearson is Canada’s largest airport, serving passengers from across the GTHA and beyond.

• Building emissions continue to be the primary source of emissions in Mississauga, while transportation remains the largest source in Brampton and Caledon.
• In Mississauga, notable industrial emissions are primarily attributed to a cement manufacturing facility.
• All municipalities experienced a reduction in natural gas emissions, with Brampton showing the largest decrease (down 7%), followed by Caledon (down 4%) and Mississauga (down 2%).
• Transportation emissions decreased the most in Caledon (down 4%), followed by Mississauga (down 1%); Brampton saw a marginal increase of 0.4%.
• Electric vehicle adoption increased across all Peel municipalities. Caledon and Mississauga led with a 30% growth of EV registrations. PHEV adoption also increased, ranging from 38% - 43% across the region.
• In 2024, ridership grew by 4% for Mississauga Transit and by 11% for Brampton Transit.
