With three satellites in orbit and plans for another seven thanks to the money from Sustainable Development Technology Canada, GHGSat said its images tracking the potent greenhouse gas will feed high-quality data to the UN’s International Methane Emissions Observatory. (The Logic)

Talking point: Canada is one of the countries at the COP26 climate-change conference in Glasgow that promised to cut methane emissions 30 per cent from 2020 levels by the end of this decade. Methane doesn’t get as much attention as carbon dioxide, but the federal government said it’s responsible for as much as 30 per cent of global warming—and a lot of the emissions are either accidental or surreptitious. GHGSat’s investors include major global petroleum companies through the industry’s Oil and Gas Climate Initiative. It says its orbital monitoring is capable of detecting pinpoint sources of escaping methane, down to individual oil or gas wells.
