A wide variety of international policy problems, including climate change, have been characterized as global public goods. This paper adopts this theoretical framework to identify the baseline determinants of public opinion about reducing greenhouse-gas emissions. We show formally that this model implies that support for climate action will be increasing in future benefits, their timing, and the probability that a given country's contribution will be decisive while decreasing in expected costs. Utilizing novel data from original surveys in France, Germany, the United Kingdom, and the United States, we provide experimental and observational evidence that expected benefits, costs, and the probability of successful provision are critical for explaining variation in support for climate action. Surprisingly, we find no evidence that the temporality of policy benefits shapes support for climate action. These results suggest effective strategies for building public support for climate action and designing institutions that facilitate global public goods provision.
