Fig. 4: Share of allocated land not available for CDR deployment under strictly enforced biodiversity conservation.
From: Biodiversity implications of land-intensive carbon dioxide removal
The results are shown for forestation (afforestation, reforestation and forest restoration), bioenergy cropland (for BECCS) and for both CDR options together for the years 2030, 2050 and 2100, based on three different exclusion criteria. The first criterion (A) excludes land from CDR allocation that is a biodiversity hotspot, regardless of the hotspot’s resilience to 1.8 °C. The second criterion (B) excludes land from CDR allocation that is a climate refugia resilient to 1.8 °C, irrespective of whether these refugia areas are biodiversity hotspots. The third criterion (AB) excludes land from CDR allocation that is a climate refugia resilient to 1.8 °C while also being a biodiversity hotspot. The robustness of the results presented here is evaluated in the Supplementary Information.
