Report: Governing large-scale carbon dioxide removal: are we ready?
In 2018, the Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5°C (IPCC SR 1.5°C) warned that the impacts of warming at 2°C would be significantly worse than those at 1.5°C. This IPCC report also found that that all pathways to achieve 1.5°C with limited or no overshoot project the use of Carbon Dioxide Removal (CDR) in the order of 100–1000 GtCO2 over the 21st century.
Is the international community prepared for the implementation of CDR options at this unprecedented scale? Can the sustainability challenges, risks and trade-offs inherent in large-scale CDR efforts be managed? What governance tools would need to be in place to deploy CDR options at the levels the IPCC says are needed? Can provisions under the current climate change regime support implementation at scale, or will further provisions and incentives be needed?
