The deployment of carbon dioxide removal (CDR) needs to be scaled up to achieve net zero emission pledges. This paper surveys the policy mechanisms currently in place globally to incentivise CDR, providing an estimate and distribution of the costs that different mechanisms currently pay per tonne of CDR. Incentive structures are grouped into three structures, market-based, public procurement, and fiscal mechanisms. The authors find that an equal or greater emphasis on policy innovation may be required if future requirements for CDR are to be met. Their study can further support research and policy on the identification of incentive gaps and realistic potential for CDR globally.
