Does social trust promote behaviour aimed at mitigating climate change?

Using international data from the Life in Transition Survey, I analyse the role of social trust on pro-environmental behaviours aimed at helping to fight climate change. Social trust might increase pro-environmental behaviour by reducing the free-rider problem, restraining opportunistic behaviour, and enhancing cooperation. The results suggest that social trust increases the probability of individuals taking personal actions aimed at helping to fight climate change; the results are robust to using different sets of control variables, and to controlling for country and region fixed effects. The results also indicate that social trust is positively and significantly associated with environmental actions that are time-consuming, but there is no significant relationship with environmental actions that impose monetary costs on individuals.
