Zusammenfassung |
BECCS (here the combination of forest-based bioenergy with carbon capture and storage) is seen as a promising tool to deliver large quantities of negative emissions needed to comply with ambitious climate stabilization targets. In many IPCC AR5 scenarios to stabilize GHG concentration at levels consistent with 2°C above pre-industrial levels, BECCS is an important feature contributing to more than 5% of global energy supply. However, a land-based mitigation option such as large-scale bioenergy production (w/o CCS) might interfere with other land-based mitigation options popular for their large co-benefits such as reforestation and reduced emissions from deforestation and degradation (REDD+). We develop a systems approach to identify and quantify possible tradeoffs between REDD+ and BECCS with the help of remote sensing and engineering modeling and apply this for illustration to South East Asia. First results indicate that prioritizing REDD+ does imply that the BECCS potential remains limited. However, reforestation has the chance to be developed into a larger portfolio of land-based mitigation options such as bioenergy and BECCS, which still have a very good mitigation potential in terms of emissions, but at the same time help to conserve and restore ecosystems. |
