Most landfills surveyed in a new report have at least one point where methane emissions exceed the legal limits, reigniting calls for stricter EPA standards.
According to an analysis released Thursday from Industrious Labs, an industry-focused decarbonization advocacy group, 21 of the 22 landfills surveyed “had significant documented methane exceedances, above the 500 ppm [parts per million] regulatory limit.”
Ten of the 22 landfills surveyed previously reported few or no exceedances. The data comes from inspection reports conducted by EPA’s compliance and enforcement office.

Landfills are one of the United States’ highest emitters of methane, a potent greenhouse gas that can capture 120 times more heat than carbon dioxide.
