Looking at food waste through the lens of climate change
Just sharing my recent overview article looking at food waste through the lens of climate change and the role of waste reduction in sustainable food systems: Can Waste Reduction Move the Needle on Food Sustainability?
Some interesting stats from my analysis (all based on 2009 data, which I had used in my research in 2011-2012):
- Total estimate of avoidable food waste in the United States is 55.41 MMT/yr, which amounts to 28.7% of total annual production by weight. This translates to 180 kg/yr of total avoidable waste on a per-capita basis, of which 110 kg represents consumer waste.
- The total GHG emissions from the production, processing, packaging, distribution, retail, and disposal of the avoidable food waste in the U.S. amounts to 112.9 MMT CO2e per year - equivalent to about 2% of national emissions (this is more of a conservative lower bound).
- Avoidable consumer waste costs a typical U.S. famiy of four approximately US$1600 per year.
