Methane emissions have decreased in two-thirds of landfills in counties that implemented composting programs after 2009, according to a sample analysis of 17 landfills across 11 counties.
Each arrow represents the change in emissions levels (in metric tons) between 2019 and the year that a municipal composting program launched in a landfill's location; right-facing arrows represent increases in emissions over time, while left-facing arrows represent decreases.
