Feds announce plan to reduce methane emissions from oil sector, landfills

Article content

OTTAWA — The federal government is announcing new regulations to cut methane emissions from the oil and gas sector and landfills.

Article content

A federal document says the new rules for oil and gas operators, which expand on regulations introduced in 2018, strengthen leak detection and repair requirements and set new standards on venting.

The new rules apply to upstream production, processing and transmission facilities in Canada’s onshore oil and gas sector, including gas plants and pipelines.

The document says the regulations will be phased in starting Jan. 1, 2028, and will help the Canadian oil and gas industry with producing “low-methane intensity products and supporting long-term success in a technologically advanced, decarbonizing industry.”

The government estimates that between 2028 and 2040 it will see a cumulative greenhouse gas emissions reduction of 304 megatonnes of carbon dioxide equivalent.

Article content

New landfill methane regulations will also require owners and operators of regulated landfills to monitor the landfill surface, landfill gas recovery wells and equipment used to control landfill methane emissions.

Article content

The federal government estimates that landfills accounted for 17 per cent of Canada’s methane emissions and three per cent of its greenhouse gas emissions in 2023. It says the regulations will allow for early detection of methane emissions and leaks that must be repaired within specified timelines.

By 2040, the regulations are expected to reduce greenhouse gas emissions by 100 megatonnes of carbon dioxide equivalent.

“This announcement is about building the strong economy of the future,” Environment Minister Julie Dabrusin said at a press conference in Burnaby, B.C. Tuesday. “One that is cleaner, more competitive and more resilient.”

In addition to the new regulations, the government is also announcing nearly $16 million in funding for investment in methane emission reduction technologies across Canada.

Article content

Methane is a greenhouse gas more than 80 times more potent than carbon dioxide over a 20-year span, but its lifetime in the atmosphere is up to a dozen years versus centuries for CO2.

Article content

The oil and gas sector is Canada’s biggest emitter of methane, the main component of natural gas. The gas can escape into the atmosphere through intentional venting, unintentional leaks from equipment and through inefficient burning.

Article content

Methane emissions reductions have been touted as one of the lower-cost tools in the climate-change-fighting tool box. The International Energy Agency said in a 2024 report that the amount of global investment needed to cut methane emissions by 75 per cent by 2030 would amount to less than five per cent of the US$2.4 trillion in net income the oil and gas industry generated in 2023.

The cost of meeting Canada’s existing draft methane targets has been pegged at $15.4 billion between 2027 and 2040.
