Support for mitigation and adaptation climate change policies: effects of five attitudinal factors

The increasing social consciousness about the causes and consequences of climate change has not led to a correspondingly high support for concrete mitigation or adaptation policies. Thus, more research is needed about the factors influencing citizen’s support for such climate change policies. In this study, we explore the effects on Spaniards’ support for one mitigation policy (car policy) and one adaptation policy (water policy) of five attitudinal factors: government response efficacy beliefs, people’s feeling of responsibility to mitigate climate change, personal self-efficacy beliefs, people’s disposition to resist change and psychological distance from climate change. We use data from an online survey implemented in the Netquest opt-in panel in Spain (N = 2290). We use structural equation modelling to control for spurious effects and test the fit of the model. Moreover, estimates are corrected for measurement errors. The results reveal that the most important factor affecting Spaniards’ support for both mitigation and adaptation policies is the perceived government response efficacy. Furthermore, we identified relevant differences regarding the importance of the above-mentioned five attitudinal factors depending on the climate change policy studied. More precisely, while government response efficacy and people’s feeling of responsibility to mitigate climate change have a direct effect on support for both policies, personal self-efficacy and people’s resistance to change only affect support for the mitigation policy directly. On the contrary, psychological distance to climate change only has a direct effect on support for the adaptation policy. Our results provide new insights into the causal mechanisms behind citizens’ support for climate change policies.
