Measuring and analyzing public perceptions of the environment are becoming core elements in promoting environmental sustainability, which is a key goal to be achieved. The New Ecological Paradigm Scale (NEP) is used as a unidimensional measure of environmental attitudes as it is developed in order to measure the overall relationship between humans and the environment. A high NEP score is associated with high ecocentric orientation. This research aims to measure and analyze citizens’ NEP score in a Greek area. Overall, the statistical analysis verified the existence of the NEP subscales, indicated increased environmental awareness among the respondents and revealed that the respondents’ NEP score is correlated with the area of residence. Furthermore, the NEP score is correlated at a statistically significant level with respondents’ willingness to pay for renewable energy expansion.
