Methane emissions, which account for roughly one-third of global warming, continue to pose a major climate challenge, according to the latest Global Methane Tracker report from the International Energy Agency (IEA). Despite mounting international concern and technological solutions already available, methane emissions from fossil fuel production have held steady at approximately 120 million tonnes annually since 2019.
Methane is a greenhouse gas roughly 80 times more powerful than carbon dioxide at trapping heat, although it breaks down much faster in the atmosphere — typically within a decade. Its rapid, intense warming potential makes it a prime target for short-term climate mitigation. Yet countries remain slow to enact policies or take action, with only about 5% of global oil and gas production currently meeting net-zero methane standards.
The IEA underscores that cutting methane emissions offers some of the most immediate climate benefits. A concerted global effort to reduce methane leaks — particularly from the fossil fuel sector — could lower global temperatures by 0.1°C by 2050. While this may sound modest, it would be equivalent to eliminating all carbon emissions from the global heavy industry sector.
Oil and gas methane emissions are among the easiest to reduce because the technology already exists and is widely proven. Approximately 70% of these emissions can be cut using known, commercially available methods. These include detecting and sealing leaks in infrastructure like pipelines, valves, tanks, and terminals. However, detection remains a challenge due to methane’s invisibility and lack of odor.
Recent advances in satellite-based monitoring have improved leak detection dramatically. The IEA report draws on data from satellite networks such as GHGSat, based in Montreal, to provide more accurate estimates. These observations reveal that actual methane releases are likely 80% higher than what countries self-report.
Canada stands out as a global leader in methane regulation and innovation. With federal targets to cut oil and gas methane emissions by 75% below 2012 levels by 2030 — far exceeding the Global Methane Pledge’s 30% reduction goal — Canada is praised for both its regulatory leadership and technological development. This proactive stance not only benefits the environment but also offers economic opportunities. As nations like Japan, South Korea, and members of the EU move to impose stricter methane emissions standards on gas imports, Canadian exporters are well-positioned to meet these evolving requirements.
Agriculture remains the largest source of human-caused methane emissions globally, followed by fossil fuels. While cutting emissions in agriculture poses more complex challenges, fossil fuel emissions can be tackled now with no need for technological breakthroughs.
The report emphasizes that beyond climate benefits, reducing methane emissions is an energy security opportunity. Methane is the primary component of natural gas; thus, minimizing leaks could make an additional 100 billion cubic meters of gas available annually — roughly equal to Canada’s entire natural gas export volume.
In conclusion, the IEA’s findings highlight the urgency and feasibility of cutting methane emissions. Despite geopolitical challenges and uneven international commitment, immediate action on methane can yield swift climate benefits, enhance energy security, and offer strong economic advantages for early movers like Canada.
