Food Production Emissions Alone Will Heat World Beyond 1.5C, Study Finds

A recent study has found that emissions from food production alone will cause global heating to surpass the 1.5C target outlined in the Paris Agreement. High-methane foods such as meat, dairy, and rice are primarily to blame for these emissions. Even if all fossil fuels were eliminated, the emissions from these foods would still push us past the international target, heating the world by 0.7C before the end of the century.

Methane, a powerful greenhouse gas that is around 80 times more warming than carbon dioxide, plays a significant role in driving the warming associated with food systems. The study suggested that adopting a diet recommended by the Harvard Medical School, which allows for only one serving of red meat per week, could limit the heating to 0.2C. Previous research has also emphasized the need for rich nations to drastically reduce meat consumption to avoid climate catastrophe, with recommendations ranging from a 90 percent reduction in beef intake to limiting meat consumption to two burgers a week.
