“The Food Sector includes agricultural production (crops and livestock) as well as food preparation, consumption, and waste. This essential human activity is responsible for a major share of greenhouse gas emissions today: crop and livestock production is the source of about 1/8 of anthropogenic emissions. Land clearing (which is mostly for agriculture) is the source of another 1/8 of emissions (IPCC, 2014). Many of Project Drawdown’s supply-side agricultural solutions reduce emissions from farming and ranching, while also sequestering significant amounts of carbon.”
