Agriculture emissions explained
Almost ¼ of greenhouse gas emissions are caused by agriculture. There are four categories to consider when looking at agriculture emissions:
Emissions in that category are produced from animals raised for meat, dairy and eggs, 31% of emissions are only caused during the on-farm ‘production’. They exclude land use, the supply chain processes and crop production for animal feed.
21% of food’s emissions are attributed to the crop production for direct human consumption, and 6% to the production of animal feed. Those emissions come from fertilizers (nitrous oxide), manure and methane for rice production. As well as CO2 from machinery.
The majority of emissions in this category are from land use for livestock (16%). 8% are attributed to crops for human consumption.
This category includes food processing, transport, packaging and retail, which require energy and resource inputs. Whilst supply chain emissions seem to be high, a lot of it is due to high food waste. Food waste emissions are substantial: one-quarter of emissions (3.3 billion tonnes of CO2eq) from food production ends up as wastage either from supply chain losses or consumers.
