2023 EPA study shows food waste contributes 55 million metric tons of CO2 emissions from MSW landfills in 2020.

New Hampshire and the US lack comprehensive food waste studies. A 2023 EPA study highlights that food waste contributed to 55 million metric tons of CO2 emissions from MSW landfills in 2020. Estimates indicate that 58% of fugitive methane emissions are from landfilled food waste, and recent studies reveal the EPA's methane detection methods at landfills may be flawed, suggesting higher emissions.
