Multi-scale direct measurements and source determination of methane emissions in Montréal

Methane is a potent greenhouse gas and reducing methane emissions is a key strategy in many climate change action plans. Because cities and their methane emissions are growing, it is essential to characterize and mitigate methane emissions from urban sources. Because there are no published studies of methane emission measurements in Montréal, we propose to conduct direct measurements to quantify methane emission rates and attribute the emissions to sources in Montréal.
