A shift from animal-based to plant-based diets in high-income nations could reduce greenhouse gas emissions and increase carbon sequestration. By simulating the EAT-Lancet planetary health diet, it could reduce annual agricultural production emissions by 61% and sequester up to 98.3 GtCO2 equivalent, fulfilling high-income nations' future carbon dioxide removal obligations. Linking land, food, climate, and public health policy is crucial for harnessing the double climate dividend.

This study needs to be checked though.
