Montreal’s Methane Hotspots Revealed in Comprehensive Urban Emissions Study
A four-year mobile monitoring survey has uncovered surprising methane sources across Montreal. The city’s largest snow dump emits methane at levels comparable to inactive landfills, challenging conventional understanding of urban emissions.
Urban Methane Mapping Reveals Unexpected Pollution Sources
Researchers from Montreal‘s McGill University have discovered that methane emissions across the city are unevenly distributed, with the highest concentrations located in the eastern sectors, according to their recently published study. The comprehensive four-year survey identified more than 3,000 methane hotspots throughout the urban landscape, with inactive landfills and the city’s primary snow dump facility emerging as significant contributors.
