Montreal’s methane emissions are unevenly distributed across the island, with the highest concentrations in the city’s east end, McGill researchers have found. The worst polluters include the city’s largest snow dump, which emits methane at levels comparable to the city's current and former landfills, and natural gas leaks.

The worst polluters include the city’s largest snow dump, which emits methane at levels comparable to the city's current and former landfills, and natural gas leaks.
The researchers identified more than 3,000 methane hotspots throughout the four-year mobile monitoring survey. They said this is fewer than comparably dense cities, but these potent emissions must be addressed.
“Though there's much less methane than carbon dioxide (CO2) in the atmosphere, every methane molecule will warm the planet by about 32 times as much as every CO2 molecule,” said Peter Douglas, Associate Professor in the Department of Earth and Planetary Sciences and study co-author. “We need to know where these emissions are coming from to resolve them.”
