The Environmental Protection Agency is underestimating methane emissions from landfills, urban areas and U.S. states. From landfills they’re 51% higher compared to EPA estimates, from 95 urban areas 39% higher, and from the 10 states with the highest methane emissions, they’re 27% higher. The largest increases were in Texas, Louisiana, Florida, and Oklahoma. Texas is responsible for 21% of U.S anthropogenic methane emissions, of those 69% from the oil and gas industry.
