Global BECCS potential is largely constrained by sustainable irrigation

Bioenergy with Carbon Capture and Storage (BECCS), a negative emission technology, has been considered inevitable to achieve the 2°C or 1.5°C climate goal. Although numerous studies have been conducted, the effect of irrigation remains largely unexplored when taking water use sustainability into consideration. A new study finds that although unlimited irrigation could increase the global BECCS potential by 60-71% by the end of this century, sustainably constrained irrigation would increase it only 5-6%.
