Methane Emissions

Berkshire Hathaway Energy’s gas pipeline businesses have significantly reduced and avoided releases of methane, thus reducing greenhouse gas emissions, enhancing pipeline integrity, making their operations safer, and reducing costs for customers through reductions in lost gas. We have developed methane reduction goals and track progress toward those goals; these goals are advanced through emphasizing leading practices and implementing strategies to limit methane emissions.
