At this very moment, an underappreciated tool for combating climate change may be hiding in your chiller drawer or at the back of your pantry. By keeping that limp carrot or dusty box of pasta out of our nation’s landfills, you can help reduce emissions of methane, a greenhouse gas 21 times more potent than carbon dioxide.
In the United States, the Environmental Protection Agency (EPA) calculates that food is the single largest component of municipal solid waste going to landfills (accounting for over 20% by weight) and that that landfills are the third largest source of methane (16% of national total). By reducing the amount of food we toss into the trash, we can help reduce these potent greenhouse gas emissions.
The benefits do not stop there, however.
