Background
Methane accounted for 117 Mt of CO₂e emissions in 2022, representing over 16 per cent of Canada’s total greenhouse gas emissions. Approximately half of these emissions (56 Mt of CO₂e) come from the oil and gas sector. In 2021, Canada became the first country to commit to a 75% reduction in methane emissions from its oil and gas sector, relative to 2012 levels, by 2030. Canada also joined over 100 countries in supporting the Global Methane Pledge to collectively reduce human-caused methane emissions. In 2018, the federal government introduced methane regulations to meet Canada’s commitment to reduce emissions from the oil and gas sector by 40 to 45 per cent below 2012 levels by 2025.

Are Western Provinces Actually reducing Methene Emissions?
Figure 1 shows methane emission reduction by province from oil and gas sector.

Particularly in 2023, Alberta’s methane emissions were just over 15 Mt CO₂e, down from 31.6 Mt CO₂e in 2014. The governments of all three provinces, together with the federal government, introduced regulations focused on technological improvements in oil and gas production. These regulations target three main sources of methene emissions: fugitive emissions (leaks), venting and flaring. An important component of methane-reduction programs is the methane measurement, reporting, and verification system. In addition, all three provinces have incentivized research and development related to methane-emission reduction. The federal government has also provided financial and technical support through R&D funding via the Methane Centre of Excellence. Finally, governments have created incentive structures that reward emissions reductions.
