Total emissions increased by 1% mostly due to the increase in building sector emissions (up 2.9%).

• Per capita emissions decreased by 2.3%, reaching 7.3 tonnes of carbon per person.
• Excluding industrial and agricultural sectors, Durham’s per capita emissions decreased slightly by 1%, reaching 5.4 tonnes of carbon per person in 2024.

• Natural gas emissions in Durham decreased by 1%, primarily due to a warmer winter. Natural gas emissions from the industrial sector increased by 12% while residential and commercial sectors decreased by 5% and 4%, respectively.
• Electricity consumption increased by 2.4%, and electricity emissions increased by 28%, driven by the increasing carbon intensity of the provincial electricity grid.
• Durham’s industrial emissions are estimated to have decreased by 3.9% in 2024, based on cement and other manufacturing production. According to recently published facility reported data, industrial emissions in 2023 decreased by 9%, largely due to emissions reported from St. Mary’s Bowmanville Cement Plant.
• Most of the GTHA's agricultural activity is concentrated in Durham, accounting for 3% of the region's total emissions. It is important to note that food produced in Durham is consumed by communities across Ontario and beyond. Agricultural emissions increased by an estimated 3.4% in 2024.
• Durham saw a considerable increase in electric vehicle registrations compared to 2023, 2,743 PHEVs (up 45%) and 8,603 EVs (up 47%), once again the highest increase in GTHA.
• Durham Region Transit saw a 20% increase in ridership in 2024, one of the highest across the GTHA.

• Transportation was the largest source of emissions in most of the lower-tier municipalities in Durham (including Ajax, Brock, Oshawa, and Pickering), which can largely be explained by lower density and reliance on personal vehicle use.
• In Whitby, building emissions are the highest contributors to the town’s total emissions.
• In Clarington, industrial emissions are the highest contributors to the town’s total emissions, primarily due to the Bowmanville Cement Plant.
• Most of the agricultural emissions in Durham come from Brock, Clarington, Scugog, and Uxbridge.
• Natural gas emissions decreased in Ajax (down 7%), Clarington (down 6%), Pickering (down 5%), and Oshawa (down 3%). Whitby’s natural gas consumption increased (up 7%). Some municipalities lacked 2023 data for comparison.
• Transportation emissions increased significantly in the following municipalities: Scugog (up 28%), Clarington (up 11%), Uxbridge (up 4%), Pickering and Ajax (up 1%), while Brock (down 7%), Whitby (down 4%), and Oshawa (down 2%) reduced their emissions.
• Municipalities in Durham saw a 47% increase in EV adoption. Brock (up 59%) and Oshawa (up 56%) led with remarkable growth. PHEV adoption also increased across all municipalities, with Whitby (up 62%) and Pickering (up 47%) leading the region.
