US EPA Releases Food Waste and Landfill Methane Report
58% of the methane from landfills comes from food waste
61% of the total methane produced is released to the atmosphere
For each metric ton of food waste that goes into a landfill you get about 0.86 tons of CO2 equivalent (CO2e) released to the atmosphere as methane — effectively a 1:1 equivalent
In 2020 landfilled food scraps released 55 million tons of CO2e to the atmosphere
