"Our results suggest that the choice and composition of future diets is highly important for GHG [greenhouse gas] emissions of the food system, as well as for society-climate interaction in its entirety.
"The feeding system of livestock is a hotspot for reducing GHG emissions. The quantity and composition of livestock feed intake is strongly and unambiguously associated with the amount of GHG emissions of the food system.
"A change in dietary demand has a large effect on sparing areas and can substantially help to increase C-uptake through vegetation regrowth. We show that today’s business-as-usual and meat-dominant diets would have the highest GHG emissions out of any dietary choice of the future option space."
