Can Defaults Save the Climate? Evidence from a Field Experiment on Carbon Offsetting Programs

Individual preferences for environmental policies can be influenced by the frame in which choices and decisions are presented. In this paper we present results of a field experiment on the contributions to carbon offsetting programs under two alternative treatments for the default option. The opt-in treatment asked subjects to pay for the policy proposal while the opt-out treatment asked subjects if they wanted to be excluded from payment for the policy proposal. The results show that the frame of the default option had a significant effect on the amount of money paid for the policy proposal. Subjects were more likely to accept the policy proposal if the default option was the opt-out treatment. The results have implications for the design of environmental policies.
