... rates, total gas vent rates, and vent gas CH 4 fractions from storage tanks at eight active upstream oil production sites in Alberta, Canada. Using a built-for-purpose optical mass flux meter (VentX) supplemented by an ultrasonic flow meter and quantitative optical gas imaging camera where possible...

... Venting The Government of Canada has committed to reducing methane (CH 4 ) emissions from the oil and gas sector by 40%–45% below 2012 levels by 2025 and, more recently, by 75% in 2030 ( Environment and Climate Change Canada [ECCC], 2020 ; 2021 ). The mitigation of this climate warming pollutant...

.... The federal regulations are found to be stronger, achieving ~26% more methane mitigation at full implementation. Key differences are in limits on pneumatic pump emissions, vented emissions, and expected reductions in fugitive emissions through leak detection and repair surveys. The full analysis was repeated...
