Methane leaks have become a key political issue between the United States and the European Union, with US officials actively opposing a new EU methane regulation that would affect major oil and gas exporters to the EU. Methane, the primary component of natural gas, is a potent climate pollutant released throughout the oil and gas supply chain. Using satellite data and air quality records, PSE identified “super-emitter” events – which they define as methane emissions exceeding 100 kilograms per hour – across 11 US states between 2016 and 2025.
