ABSTRACT A growing body of large-N cross-national studies has identified key predictors of environmental behavior. Adopting a social dilemma perspective, where individuals must choose collective over self-interest to act pro-environmentally, integrated national datasets for 30 countries are used to examine the effects of generalized trust, trust in government, leftism, and post-materialism on three types of environmental behavior (intended action, informal action, and formal action). At the individual level, all predictors but institutional trust have significant positive effects on each type of behavior. Institutional trust is associated with greater willingness to make economic sacrifice for the environment and with less frequent informal environmental behavior, but it is unrelated to formal behavior. However, at the country level, the effect of trust is limited to intended behavior and depends on the type of trust. Individuals in countries with higher generalized trust averages are less willing to sacrifice for the environment, and those in countries with higher averages of institutional trust are more willing to do so.
