On Nov. 21st, Pennsylvania Gov. Tom Wolf announced his administration would pursue a now-approved emergency rulemaking to finalize long-overdue volatile organic compound and methane rules for the conventional oil and gas industry.
It’s no surprise that COP 27 in Sharm El-Sheikh, Egypt closed with few groundbreaking headlines. Going in, we knew it would be a “working COP” focused on steps to advance the commitments made at previous gatherings. And while some important steps were made on technical issues and a historic agreement on funding arrangements for loss and damage was sparked, there was real progress in the fight to reduce methane, the pollutant driving nearly a third of current warming.

After three years of actively collecting methane emissions data in the Permian Basin, researchers have gained new insights that will make it easier to reduce emissions of the incredibly potent greenhouse gas methane. These insights are helping inform state and federal regulatory approaches at a critical time.

Canada has set arguably some of the most ambitious goals of any country when it comes to reducing emissions of the potent greenhouse gas methane. In addition to joining a global coalition of countries pledging to reduce 30% of their methane emissions, Canada has also vowed to reduce oil and gas sector emissions even further, by 75%.
But how close is Canada to reaching that goal? New research published this week in the journal Elementa reveals it is almost impossible to accurately answer that question with our current policies.
Here’s why.

Methane emissions from natural gas gathering pipelines in the U.S. Permian Basin are at least 14 times greater than Environmental Protection Agency national inventory estimates, according to new peer-reviewed research from EDF, Stanford University and the University of Arizona. Gathering lines transport unprocessed gas from well sites to processing facilities and vary widely in size and pressure, with diameters ranging from two inches to as large as 30 inches. Methane is a potent greenhouse gas with over 84 times the warming potential of carbon dioxide over its first 20 years in the atmosphere, and this new research indicates the importance of finding and fixing pipeline methane leaks to mitigate the climate crisis.
A new study out today in the journal Science finds that climate-warming methane emissions from flaring, the practice of burning off gas rather than capturing it for productive use, are five times higher than government estimates — primarily due to unlit and malfunctioning flares. Researchers conclude that flares are combusting at a 91% efficiency rate, significantly lower than the 98% efficiency rate that is assumed by operators and policymakers.
These findings confirm that our current environmental standards are not adequately controlling this pollution source and underline the need for urgent regulatory action from the Environmental Protection Agency and Bureau of Land Management to limit pollution and waste from flaring.
