There are numerous studies assessing the influence of individual sociological, political, and demographic factors on attitudes towards climate change. However, there is still a need for a deeper understanding of the reasons behind these attitudes and for research based on results from more than one country. This study empirically examines a range of psychosocial and demographic determinants of support for climate policy (renewable energy, energy efficiency and carbon tax) in Germany and Poland (n = 1969). The results show that the societies of both countries, despite significant differences in income, culture and political stance on climate change, similarly support implementation of climate policies. For both countries valid predictors of support are: awareness, emotional response to climate crisis, sense of control, and belief in effectiveness of solutions; the study also shows predictors relevant in only one country. Factor analysis identified similar dimensions of attitudes toward climate change in both countries. The main findings show that support for climate policy is high in both countries and that the public is ready to accept more ambitious climate goals. Despite the differences between the countries, a coherent climate policy seems justified. The study also shows differences between the countries and provides recommendations for policymakers.

This article presents the results of a quantitative survey conducted on 4000 electric energy consumers in Spain, France, Italy, and Denmark. The results demonstrate differences in the effects of additional remuneration for using vehicle-to-grid (V2G) stations, depending on users’ reasons for saving electricity. Individuals with extrinsic financial motivations are sensitive to such incentives; the higher the remuneration is, the more willingness they demonstrate to use V2G. Although individuals with intrinsic (the desire to control spending) and ecological (caring for the environment) motivations are also interested in using V2G, no relationship can be observed between the sizes of the rewards and individuals’ desire to use the technology. Users are similarly encouraged by low (an extra 2.5% of energy for free) and high (an extra 20%) rewards. In contrast, individuals who display intrinsic general modesty (willingness to not waste things) motivations may even be discouraged: the higher the reward, the less interest they demonstrate in V2G. The article illustrates how different types of motivation can affect users’ interest in the innovative V2G concept, as well as underlining the importance of constructing intrinsic and altruistic motivations in the process of education.
