This report by Ember evaluates the financial risks and technical viability of announced greenhouse gas removal (GGR) projects in the UK, specifically focusing on bioenergy with carbon capture and storage in the power sector (power-BECCS) and direct air carbon capture and storage (DACCS). The analysis finds that these technologies are currently unproven at commercial scale, face significant delivery delays, and could require billions in public subsidies, potentially diverting funds from more effective decarbonisation methods like renewables and heat pumps.

This research paper by the NewClimate Institute examines policy frameworks for upscaling Carbon Dioxide Removal (CDR) while ensuring that such efforts do not detract from greenhouse gas emissions reductions. The authors analyze various CDR approaches, their development stages, and the risks associated with using offsetting schemes, ultimately advocating for the separation of emission reduction targets from removal targets.

This appendix from the IPCC Working Group III report provides a detailed technical summary of various Carbon Dioxide Removal (CDR) methods, comparing their technology readiness levels (TRL), costs, mitigation potentials, and associated risks and co-benefits.
