A new study published in Science Advances found that a more sustainable, flexitarian diet increases the feasibility of the Paris Agreement's climate goals in a variety of ways.

"Reducing greenhouse gas emissions related to dietary changes, particularly methane from ruminants raised for meat and milk, would allow us to expand our current global CO budget ₂ at the height of 500 gigatons by 125 gigatons and still stay within the limits of 1.5°. C with 50% chance," says Florian Humpenöder, PIK scientist and co-author of the study.

Pricing greenhouse gas (GHG) emissions in the energy and land system is an important policy tool for staying within the 1.5°C warming limits. (More on phys.org)
