“Our diet is very heavy on meat and therefore requires a lot of fertile land for livestock farming and feed production,” the researcher notes. These emissions could be reduced by up to 70 per cent through a reduced consumption of beef and dairy products.

Traditional analyses typically attribute only a small share of overall emissions to diet and thus also underestimate the potential of changed eating habits for climate protection. “Our approach makes it possible to determine both, the climate efficiency of the production and that of the consumption of agricultural goods,” Beringer says. For effective climate protection requires changes on both sides, i.e. reduced consumption of products that are connected to high greenhouse gas emissions along with more efficient use of arable land and pasture.
