STUDY: Replacing animal products can free up land to tap vast energy and negative emission potentials
OSCAR RUEDA: To limit global warming at 1.5°C, climate mitigation pathways project the need to remove 100–1,000 billion tonnes of carbon dioxide from the atmosphere. Bioenergy with carbon capture and storage (BECCS) has been the most prominent carbon removal method considered. However, massive BECCS deployment would likely require cropland expansion to produce the biomass feedstock needed. Such an expansion may worsen biodiversity due to the loss of natural land and food and water security due to competition for land and water resources.
A transition from consuming animal-source proteins to…
