Carbon removal is an essential complement to emission reductions, serving as a critical pathway for achieving net-zero and net-negative emissions strategies. Key considerations include its limitations: carbon storage options vary in permanence and risk, and removal should follow a mitigation hierarchy prioritizing emission avoidance or reduction. The greatest near-term opportunity lies in reforestation and soil carbon approaches, though opportunities to deploy carbon dioxide removal technologies at scale require urgent support. To effectively engage with carbon removal, leaders should prioritize ambitious decarbonization targets, phase out reliance on offsets to compensate for unavoidable emissions, and advocate for policy frameworks that accelerate the transition. Carbon removal solutions face challenges related to measurement, the risk of reversal, and limited additionality or baselines.
