Bioenergy with carbon capture and storage (BECCS), as a negative emission technology, has been assigned a key role for achieving ambitious mitigation targets in several climate models. One of the main challenges to deploy BECCS at the level required in the stringent emission scenarios is expanding sustainable bioenergy production. Intensification of bioenergy production could result in severe pressure on natural resources, especially land and water, and competition between food, feed, and energy. Thus it potentially could lead to controversial economic, ethical, and environmental issues. To avoid the social uncertainties and environmental impacts resulting from dedicated energy crop production, BECCS potential has to be restricted to the presumption of no land-use expansion and no increase in water consumption. |
