Canada Records 691 Million Tonnes in Greenhouse Gas Emissions for 2025
Canada’s greenhouse gas emissions ticked upward by approximately one percent in 2025 to reach 691 million tonnes of carbon dioxide equivalent, according to the annual national emissions report released by the Canadian Climate Institute. The total volume matches the annual output of 161 million gas-powered passenger vehicles driven for a single year. The institute receives three-quarters of its funding from the federal government and published these early figures ahead of official federal estimates expected in April.
The upward tick leaves the country further behind its international climate obligations. Ross Linden-Fraser, acting director of the climate institute’s 440 Megatonnes division, stated that Canada faces a widening gap against its self-imposed targets. “We might be as much as 20 years behind on achieving our 2030 target,” Linden-Fraser said. Under the Paris climate change accord, Ottawa committed to cutting emissions by 40 to 45 percent below 2005 levels by 2030, and reaching net-zero emissions by 2050.
Oil and Gas Sector Lowers Emissions Amid Record Crude Production
Despite record crude production, Canada’s oil and gas sector reduced its emissions by 0.2 percent in 2025 compared to the previous year. Statistics Canada figures from June noted that the country produced roughly four percent more crude oil in 2025 than in 2024. While oilsands emissions increased by 844,000 tonnes year-over-year, reductions in conventional extraction and downstream activities outpaced those rises by trimming 1.3 million tonnes.
Seton Stiebert, a senior fellow at the climate institute, attributed the progress to fugitive methane emission reductions and higher operational efficiency per unit produced. “The oil and gas sector is finding ways to use less energy to extract, store and ship oil,” Stiebert said. Government figures indicate Canada has achieved an emissions reduction of 10.3 percent below 2005 levels over a 21-year span, while the climate institute’s latest independent assessment places the reduction at 9.5 percent.

Winter Weather and Natural Gas Drive Building and Power Sector Increases
Commercial structures and residential homes served as the primary drivers of the country’s overall emissions increase in 2025. Linden-Fraser pointed to a colder winter as the immediate catalyst for higher heating demands, noting that the sector’s heavy reliance on fossil fuels makes buildings highly sensitive to temperature drops. Increased electricity generation from natural gas further compounded the rise.
Although the power sector transitioned away from coal and heavy petroleum products over the past two decades, rising reliance on natural gas has established a baseline limit on total potential reductions. The federal government released a national electricity strategy earlier in the year that relies on natural gas to help double the capacity of Canada’s electrical grid by 2050, citing affordability and fast generation response times.
Prime Minister Carney Shifts Climate Policy Toward Affordability and Energy Growth
The modest emissions increase coincides with a transition in federal climate strategy under Prime Minister Mark Carney. In a June video address, Carney criticized prior policies under Trudeau as overly expensive and divisive, acknowledging that national emissions would likely rise in the near term.
Why Canada Oil and Gas Emissions Dropped
Why did Canada’s oil and gas emissions drop despite record production?
Emissions fell by 0.2 percent in 2025 because reductions in conventional oil and gas extraction and downstream activities—totaling 1.3 million fewer tonnes—offset an 844,000-tonne increase from oilsands upstream producers. Institute experts cited fugitive methane emission reductions and increased operational efficiency as key drivers.
How far behind is Canada on its 2030 climate target?
Ross Linden-Fraser of the Canadian Climate Institute stated that Canada may be as much as 20 years behind in achieving its goal to cut emissions by 40 to 45 percent below 2005 levels by 2030.
What sector caused the largest increase in overall emissions for 2025?
Buildings, including commercial structures and residential homes, drove the largest share of the emissions increase, largely due to a colder winter that intensified fossil fuel heating demands.
