Analyzing differences between different types of pro-environmental behaviors: Do attitude intensity and type of knowledge matter?

This study explores whether the associations between general environmental attitudes and pro-environmental behaviors are heterogeneous and whether these associations depend on attitude intensity and the specific pro-environmental behavior. The study also examines the association between objective and subjective knowledge and behavior and the relationship with socioeconomic and personal characteristics. Mixed effects logistic regressions were performed using data from a representative nationwide survey of Spanish citizens aged 18 to 90 years (N = 2495). The results revealed interesting patterns of heterogeneity. First, only curtailment behaviors (separating trash and using street trash cans) were significantly associated with general environmental attitudes. This result was observed only for the highest level of environmental attitudes. Second, whereas subjective knowledge was associated with all pro-environmental behaviors, objective knowledge was only associated with efficiency behavior (using energy-efficient light bulbs). Finally, men showed lower levels of reported behavior than women for all pro-environmental activities. The policy implications of these findings are discussed
