Abstract:
Pathways aligned with global climate goals typically rely on deploying billions of tonnes of carbon dioxide removal (CDR) through land-intensive approaches such as forestation and bioenergy with carbon capture and storage. However, using these methods at large scale can pose risks to biodiversity. In this study, we examine scenarios from five integrated assessment models and find that pathways consistent with limiting warming to 1.5 °C dedicate as much as 13% of global areas of high biodiversity importance to land-intensive CDR. These overlaps are unevenly distributed, with a greater share occurring in low- and middle-income countries. Recognizing potential conflicts between climate action and biodiversity conservation is essential. An illustrative analysis suggests that if today’s biodiversity hotspots were shielded from land-use change, more than half of the land assigned to forestation and BECCS in the assessed scenarios would no longer be available, unless synergies between climate and conservation goals are leveraged. Our results also point to biodiversity benefits from CDR associated with avoided warming.
The webinar format will consist of a 20-minute presentation and a 10-minute discussion with an invited expert stakeholder, followed by a 30-minute open discussion (1 hour total).
