Canada has announced long-promised rules aimed at dramatically reducing methane emissions from the country’s oil and gas sector.

The regulations, announced on Tuesday, lay out a path for Canada – the world’s fourth-largest oil producer – to cut by 2035 its overall emissions of the potent greenhouse gas by 75 percent over 2014 levels.

They fulfil a promise by Prime Minister Mark Carney to strengthen Canada’s existing methane rules, but allow for a slightly longer target timeframe than the previous draft rules announced under Carney’s predecessor, Justin Trudeau.
