Food waste worsens climate change

An estimate of 30 to 40 percent of food in the U.S. is wasted. When food gets wasted, inputs used to store, process, transport, and prepare the food are also wasted. Not only does food waste impact the inputs, but its use of greenhouse gases is worsening climate change. 

The U.S. Environmental Protection Agency (EPA) published a report in 2021 that said, every year, U.S. food loss encompasses 170 million tons of carbon dioxide equivalent, GHG emissions. The EPA compared it to the annual carbon dioxide emissions of 42 coal-fired power plants. 

The combination of food waste in landfills, which accounts for about 23 percent of total landfilled waste, and methane burped from cows makes up for a significant number of Earth’s total methane emissions. 12 percent of methane emissions come from livestock manure. In addition, agriculture makes up 11 percent of total greenhouse gas emissions in the U.S.

To prevent food waste from increasing, Dana Gunders, executive director of ReFED, an organization that examines food waste, said during a committee meeting that standardized food labeling would make a large impact. Right now, different types of food have different labels, including “best by,” “sell by,” and “enjoy by.” Gunders said creating a standard would help stunt climate change.
