Many things contribute to climate change, including emissions from oil and gas operations. With Alberta at the heart of Canada’s oil and gas sector, we collaborated with the Government of Alberta to protect our environment by reducing methane emissions.
When the Government of Alberta announced its Climate Leadership Plan in 2015, we were tasked with developing requirements to reduce methane emissions from upstream oil and gas operations by 45 per cent (relative to 2014 levels) by 2025.
What is methane?
Methane is a colourless, odourless, flammable greenhouse gas. It is the main constituent of natural gas. The global warming potential of methane is significant—it is estimated to be 25 times greater than that of carbon dioxide over a 100-year period.
In Alberta, the oil and gas industry is the largest source of methane emissions—in 2014 it accounted for approximately 70 per cent of province’s methane emissions.
Approach to Methane Reduction
To meet the goal set out by the Government of Alberta, we developed regulatory requirements within Directive 060: Upstream Petroleum Industry Flaring, Incinerating, and Venting, and Directive 017: Measurement Requirements for Oil and Gas Operations. Draft requirements were released for public comment in April 2018, and in December, 2018, we released the revised editions.
The new edition of Directive 060 comes into effect on January 1, 2020, including the methane reduction requirements. The new edition of Directive 017 is effective immediately following its release.
The requirements address the primary sources of methane emissions from Alberta’s upstream oil and gas industry: fugitive emissions and venting, which includes emissions from compressors, pneumatic devices, and glycol dehydrators. The requirements also focus on improved measurement, monitoring, and reporting of methane emissions.
While we authored the new requirements, the Government of Alberta played a key role by setting the policy direction.
How the Requirements Were Developed
Alongside the Government of Alberta, we held multistakeholder committee meetings to develop options to inform the new methane reduction requirements. The committees had representatives from environmental nongovernment organizations, the oil and gas industry, and technology groups.
