Food waste refers to food that is produced but not eaten. This can occur for a variety reasons such as people purchasing more food than they need or customers rejecting bruised or mis-shaped produce. Food waste also can occur when food rots on farms or in the distribution process. Food waste generates GHGs in every step of the food production and distribution process. Organic matter also produces methane, a potent GHG, when it decomposes in landfills.
