CLIMATE CHANGE BELIEFS, IDEOLOGICAL ORIENTATION, AND ENVIRONMENTAL VALUES: AN EMPIRICAL CROSS-COUNTRY ANALYSIS Andreas Ziegler, University of Kassel, phone: +49 561 804-3038, email: [email protected] Overview Climate change is widely considered as a multi-faceted challenge due to its strong impacts on the natural environment and human lives. In order to limit the increase in global temperatures, drastic reductions of greenhouse gas emissions, especially carbon emissions, from energy conversion and use, but also efforts to adapt to consequences of unavoidable climate change are needed. However, international climate negotiations were not successful so far. Former negotiations have shown that their success involves several challenges such as the cooperation between very heterogeneous countries or the translation of agreements into national regulations. One of the main conditions for successful international climate policy is the acceptance of negotiations and agreements by citizens. While a necessary condition for the willingness of citizens to support policies for (possibly costly) adaptation activities to reduce negative impacts of climate change is that people believe in the existence of climate change, a necessary condition for the support of policies for mitigation activities is the belief in the existence of anthropogenic climate change. While most citizens worldwide believe in anthropogenic climate change, in several countries a substantial minority of people is skeptical. Therefore, the knowledge about the extent and particularly the determinants of global warming beliefs and beliefs in anthropogenic global warming is very important. According to former studies, the USA is one of the countries with the highest frequency of climate change skeptics. Econometric analyses have shown that the political and ideological orientation and identification is a main determinant of climate change beliefs in this country: Conservatives and Republicans have strongly lower beliefs than liberals and Democrats. One possible explanation for this result is that conservatives have stronger system justification tendencies, which lead them to defend the status quo and to deny problems such as climate change that threaten the system functioning. While former studies almost exclusively focus on the USA, this paper compares the global warming beliefs in three countries, which are key players in international climate policy, namely the USA, Germany (as largest country in the European Union), and China. The empirical analysis is based on data from simultaneous representative computerbased surveys among a total of more than 3400 citizens aged 18 and older (1010 respondents in the USA, 1005 respondents in Germany, 1430 respondents in China). In contrast to former studies, we consider both general climate change beliefs and beliefs in anthropogenic climate change. With respect to the determinants of these beliefs, we conduct a more detailed analysis of political and ideological orientation and identification and especially examine whether possible differences between a conservative-right orientation and a green-left orientation are only indirect and thus influenced by other views and values such as environmental awareness. Methods Micro-econometric analysis with discrete choice models. Results In line with former studies, our empirical results reveal that in the USA the frequencies of climate change beliefs (79%) and of beliefs in anthropogenic climate change (69%) are lower than in Germany (90%, 87%) and particularly in China (98%, 95%). Furthermore, our preliminary econometric analysis shows that in all three countries education has no significant effect on global warming beliefs and beliefs in anthropogenic global warming. For the USA it is confirmed that conservatives have strongly lower beliefs. However, while liberals seem to have higher climate change beliefs (although not significantly different beliefs in anthropogenic climate change), the effect is strongly influenced by the positive effect of a green identity. Overall, ideological differences in climate change beliefs in the USA are partly only indirect and strongly decrease if environmental awareness is included in the econometric analysis. In contrast, the ideological differences in climate change beliefs are lower in Germany. In line with the results in the USA, environmental awareness plays the major role in explaining climate change beliefs and beliefs in anthropo- genic climate change in Germany and also in China, where further determinants cannot be identified due the high frequencies of beliefs. Conclusions The main condition for the support of climate policies and thus sustainable energy policies is that people are convinced that these policies are generally necessary due to the existence of climate change and particularly anthropogenic climate change. According to our empirical results, the frequencies of climate change skeptics are rather low in Germany and extremely low in China so that this skepticism does not seem to be an important factor for the limited support of climate and sustainable energy policies. In particular, political and ideological orientation are obviously not very important in Germany and thus probably in whole Europe. Our result of the strong relevance of environmental awareness for ideological differences in the USA suggests that communication and information campaigns in order to reduce climate change skepticism could formulate messages around issues other than global warming such as nature, plant, and animal protection.
