Methane (CH₄) is a greenhouse gas that is primarily emitted from animal agriculture, energy production, and landfills. Methane is also the primary contributor of ground-level ozone, which causes 1+ million premature deaths every year and millions more chronic diseases. 

EGD researchers lead a project to identify methane emissions in California. . Led by Berkeley Lab, with partners at Pacific Gas and Electric, California Resources Corporation, California Air Resources Board, and the U.S. Environmental Protection Agency, the project’s goal is to design a framework for fast, accurate methane emissions identification and monitoring in California’s Southern San Joaquin Valley, a high-emissions hotspot, and then expand it statewide.
