Bioenergy could slash emissions, but demands massive land use
Bioenergy with carbon capture and storage (BECCS) can help reduce global warming by capturing and storing carbon dioxide. A study found that BECCS can produce negative emissions, but the amount depends on factors like where the biomass is grown and how it's used. The research shows that BECCS could potentially sequester 2.5 billion tons of CO2 per year for 30 years, increasing to 40 billion tons per year over 80 years. However, because BECCS requires a lot of land, it should be used carefully and early on to limit its impact.
