Mobile Methane Measurements Across Toronto

Summary: Methane is a greenhouse gas that has 28 times the global warming potential of CO2 over the first 100 years of entering the atmosphere. Reducing methane emissions will therefore have an immediate impact on climate change. To this end, correctly quantifying methane emissions is a crucial step towards slowing the earth's heating rate. For my summer project, I am identifying, measuring, and analyzing atmospheric methane concentrations across Toronto using a mobile survey system, planning routes in an equitable manner over diverse neighborhoods. For this project, I ride a bicycle with the mobile system attached around different areas and publish the data to a public website. In one of my rides around Ashbridges Bay, I identified a plume close to the main sewage treatment plant. Finding places such as this will help identify methane emitters and allow the City of Toronto to better focus its future policies and efforts on methane emission reduction to ensure a net-zero future for all.
