"(...) Bioenergy with carbon capture and storage (BECCS) can help stabilize the climate by extracting carbon dioxide
from the atmosphere while producing renewable energy. However, biomass availability would limit the potential of
BECCS, and biomass cropland expansion may threaten biodiversity, food security, and water supply. Replacing land-
intensive foods can help unlock sustainable biomass production. Here, we estimated BECCS energy and negative
emissions using biomass grown on freed-up land when replacing animal-source foods. Biomass production excludes
agricultural expansion to protect biodiversity, ensures enough food supply globally to safeguard food security, and
constrains irrigation to secure water for people and ecosystems. Negative emissions consider supply chain emissions
and the forgone sequestration from natural revegetation. Results show that replacing 50% of animal products by
2050 could release enough land for BECCS to generate 26.4–39.5 EJelec/year, the scale of coal power today, while
removing 5.9–9.3 GtCO2e/year from the atmosphere, almost what coal power emits today. (...)"
