A Net-Zero Target Compels a Backward Induction Approach to Climate Policy
This article, published in Nature Climate Change, explores the importance of credibility in climate policy.
Abstract
Jurisdictions worldwide increasingly affirm their contributions to the Paris Agreement by pledging net-zero targets. We argue that delivering on net-zero targets compels a backward induction approach to climate policy, which stipulates that maximizing credibility should be the objective of policy pathways design. This implies choosing policies that strike a suitable balance between building commitment and attaining cost efficiency. Our argument rests on the premise that private investments play a key role for net zero, and that getting expectations right—through credible commitment to a policy pathway—is more relevant than getting the prices right to align the investments with net zero. We sketch the main elements for a regulatory strategy to put this approach into action.
