View article: Most landfill methane emissions Escape detection in EPA21 surface emission monitoring surveys
Most landfill methane emissions Escape detection in EPA21 surface emission monitoring surveys Open
We measured emissions from ten landfills using mobile surveys and Surface Emission Monitoring (SEM) to determine what fraction of emissions can be identified by SEM surveys. SEM is commonly used for regulatory compliance and leak detection…

A controlled release experiment for investigating methane measurement performance at landfills Open
We assessed the performance of various methane measurement solutions in landfill applications. A measurement solution is defined as a system or market offering that quantifies and/or localizes emissions. Our study involved full-scale multi…

Active Face Emissions: An Opportunity for Reducing Methane Emissions in Global Waste Management Open
This study used mobile surveys of ten Canadian landfills to assess how methane emissions varied across different landfill sources and operational conditions. The studied landfills included two closed landfills, four open landfills equipped…

Mitigating Methane Emissions: A Comprehensive Measurement Study of Canadian Landfills Open
Canada’s waste sector contributes 23% toward national methane emission totals. Recently Canada committed to a 50% reduction in waste sector methane emissions by 2030 from 2020 levels, as part of its Global Methane Pledge action plan.…

Aerial Assessment of Methane Emissions from Canadian Landfills Open
Canada is committed to reducing methane emissions by 50% below 2020 levels by 2030 in alignment with the Global Methane Pledge. The waste sector accounts for 23% of Canada’s methane emissions, and accurate estimations of current emis…

Sea–air methane flux estimates derived from marine surface observations and instantaneous atmospheric measurements in the northern Labrador Sea and Baffin Bay Open
Vast amounts of methane (CH4) stored in submarine sediments are susceptible to release in a warming Arctic, further exacerbating climate change in a positive feedback. It is therefore critical to monitor CH4 over pan-regional scales to det…

Underestimation of reported methane emissions, and air pollutant loadings, from upstream oil and gas activities in Canada Open
Canada was an early adopter of methane regulation in the oil and gas sector, and recently announced a more ambitious goal to reduce 75% of methane emissions by 2030. New stricter methane regulations should also help reduce loading of air p…

A comparison of methane source localization methods in landfills across Canada using truck-based measurement, Lagrangian stochastic back trajectory modeling, and Landsat thermal images Open
Canada is a signatory to the Global Methane Pledge and is aiming to achieve a 75% cut in methane from 2030 levels from oil and gas production through regulatory updates and a 50% cut in waste sector emissions using new regulations. Despite…
View article: Methane emissions from upstream oil and gas production in Canada are underestimated
Methane emissions from upstream oil and gas production in Canada are underestimated Open
<div>Methane emissions were measured at ~7000 sites across major oil and gas producing regions in Canada to examine regional emission trends, and to derive an inventory estimate for Canada&#8217;s upstream oil and gas sector. Emi…
View article: Airborne emissions of methane at offshore oil platforms in Newfoundland and Labrador, Canada
Airborne emissions of methane at offshore oil platforms in Newfoundland and Labrador, Canada Open
<p>In Canada, offshore oil production facilities are exempt from new methane mitigation requirements that apply to onshore producers. Since onshore oil and gas operations have been shown in Canada to emit more methane than is reporte…
View article: Quantification of methane emissions from anthropogenic sources: A case study in Canada
Quantification of methane emissions from anthropogenic sources: A case study in Canada Open
<p>Anthropogenic methane emissions are generated in several economic sectors, including agriculture, waste management, oil and gas production, and others. Canada is one of the world&#8217;s largest oil and gas producers, ranks in…
View article: Active and inactive oil and gas sites contribute to methane emissions in western Saskatchewan, Canada
Active and inactive oil and gas sites contribute to methane emissions in western Saskatchewan, Canada Open
The oil and gas industry is Canada’s largest contributor to national methane (CH4) emissions. To quantify the input of active and inactive (suspended and abandoned) oil and gas infrastructure to regional CH4 budgets, we conducted truck-bas…
View article: Methane emissions from conventional and unconventional oil and gas production sites in southeastern Saskatchewan, Canada
Methane emissions from conventional and unconventional oil and gas production sites in southeastern Saskatchewan, Canada Open
Energy development in southeastern Saskatchewan, Canada, is unique because conventional and unconventional oil and gas production is co-located. Mobile surveys are ideal for understanding emissions in this area because the overlap of produ…

Methane emissions from contrasting production regions within Alberta, Canada: Implications under incoming federal methane regulations Open
Aggressive reductions of oil and gas sector methane, a potent greenhouse gas, have been proposed in Canada. Few large-scale measurement studies have been conducted to confirm a baseline. This study used a vehicle-based gas monitoring syste…
