Shocking food waste numbers

I've actually seen estimates over the years, from various sources, ranging from 25-40%. If you click on the link below, then on "new estimates" in the first paragraph, and start looking around, you can see that this outfit has clearly done its homework.

ReFED has released new estimates on the extent, causes, and impacts of food loss and waste in the United States, as well as an updated analysis of the solutions needed to fight it. The findings represent a stark call to action for food businesses, funders, policymakers, and other food system stakeholders to dramatically ramp up the investments, operational changes, and policy shifts that are critical to cutting the amount of food going to waste in the country. The new data comes from the ReFED Insights Engine, an online hub for data and solutions that features the most comprehensive examination of food waste in the U.S., now updated to include estimates through 2021.

According to ReFED, in 2021 the U.S. generated 91 million tons of “surplus food,” defined as all food that goes unsold or uneaten. This represents 38% of U.S. food supply and contributes nearly 6% of the country’s annual greenhouse gas emissions – the equivalent of driving 83 million passenger vehicles for one full year. Close to 50% of this surplus was generated by households, with another 20% generated by consumer-facing businesses. And while 80% of total surplus food was edible parts, less than 2% was donated.

Beyond emissions, producing food that goes unsold or uneaten uses 22% of U.S. freshwater and 16% of cropland. Wasted food is also a drain on the economy, since food that goes uneaten still costs money to grow, harvest, transport, cool, prepare, and then ultimately dispose of. ReFED’s analysis places the value of food that went unsold or uneaten at $444 billion in 2021, approximately 2% of U.S. GDP. What’s more, the amount of food that goes uneaten is the equivalent of 149 billion meals’ worth of food that could have gone to the 10% of Americans who struggle with food insecurity. - ReFED
