The Global Benefits of Reducing Food Loss and Waste, and How to Do It

One-third of all food produced globally by weight is lost or wasted between farm and fork — that’s more than 1 billion tonnes. Converted into calories, this equates to 24% of the world’s food supply going uneaten. At the same time, 1 in 10 people globally remain malnourished.This scale of food loss and waste harms not only human health and nutrition but also economies and the environment. Wasted food takes a major financial toll, costing the global economy more than $1 trillion every year. It also fuels climate change, accounting for approximately 8%-10% of global greenhouse gas emissions.
