Encouraging politicians to act on climate: A field experiment with local officials in six countries

Local governments play an important role in addressing the climate crisis. However, despite public support for climate action, local policy responses have been limited. We argue that (1) biased beliefs about voter preferences, (2) the time horizon for credit claiming, and (3) source credibility are barriers for legislators to learn and adopt new environmental policies. We test these arguments in a real policy‐learning context. Representatives from six Western countries received customized invitations to a webinar on climate solutions for local governments. We find that constituency opinion on climate issues made local office‐holders more responsive to public preferences. Invitations sent by a climate scientist and emphasizing shorter term policy effects increased interest in the webinar, but did not boost the likelihood of policy commitments. Only US officials responded negatively to climate scientists. The results reveal concrete steps to induce climate action and contribute to scholarship on policy learning.
