This chapter explores two distinct approaches, carbon dioxide removal (CDR) and solar radiation modification (SRM), as potential means to counteract climate change, providing additional angles to the SWOT analyses conducted in the previous chapters. CDR methods, both technological and natural, vary in terms of cost, permanence, and removal potential. Governance challenges, such as avoiding moral hazard and ensuring permanence, are critical to implementing large-scale CDR. International governance frameworks like the UNFCCC will play significant roles in shaping CDR policies. Conversely, SRM presents a faster and cheaper but imperfect option, with stratospheric aerosol injection being the most plausible form. Environmental and political risks associated with SRM recommend multilateral decision-making and coordination. Despite research in certain countries, global governance mechanisms remain largely silent on SRM. International political dynamics may influence the trajectory of SRM development and deployment. Ultimately, the fate of both CDR and SRM hinges on international cooperation.
