The effect of tailored information, goal setting, and tailored feedback on household energy use, energy-related behaviors, and behavioral antecedents

In this multidisciplinary study, an Internet-based tool was used to encourage households (N=189) to reduce their direct (gas, electricity and fuel) and indirect energy use (embedded in the production, transportation and disposal of consumer goods). A combination of tailored information, goal setting (5%), and tailored feedback was used. The purpose of this study was to examine whether this combination of interventions would result in (i) changes in direct and indirect energy use, (ii) changes in energy-related behaviors, and (iii) changes in behavioral antecedents (i.e. knowledge). After 5 months, households exposed to the combination of interventions saved 5.1%, while households in the control group used 0.7% more energy. Households exposed to the interventions saved significantly more direct energy than households in the control group did. No difference in indirect energy savings emerged. Households exposed to the interventions adopted a number of energy-saving behaviors during the course of the study, whereas households in the control group did so to a lesser extent. Households exposed to the interventions had significantly higher knowledge levels of energy conservation than the control group had. It is argued that if the aim is to effectively encourage household energy conservation, it is necessary to examine changes in energy use, energy-related behaviors and behavioral antecedents.     

Meta-analysis of human connection to nature and proenvironmental behavior

Understanding what drives environmentally protective or destructive behavior is important to the design and implementation of effective public policies to encourage people's engagement in proenvironmental behavior (PEB). Research shows that a connection to nature is associated with greater engagement in PEB. However, the variety of instruments and methods used in these studies poses a major barrier to integrating research findings. We conducted a meta-analysis of the relationship between connection to nature and PEB. We identified studies through a systematic review of the literature and used Comprehensive Meta-Analysis software to analyze the results from 37 samples (n = 13,237) and to test for moderators. A random-effects model demonstrated a positive and significant association between connection to nature and PEB (r = 0.42, 95% CI 0.36, 0.47, p < 0.001). People who are more connected to nature reported greater engagement in PEB. Standard tests indicated little effect of publication bias in the sample. There was significant heterogeneity among the samples. Univariate categorical analyses showed that the scales used to measure connection to nature and PEB were significant moderators and explained the majority of the between-study variance. The geographic location of a study, age of participants, and the percentage of females in a study were not significant moderators. We found that a deeper connection to nature may partially explain why some people behave more proenvironmentally than others and that the relationship is ubiquitous. Facilitating a stronger connection to nature may result in greater engagement in PEB and conservation, although more longitudinal studies with randomized experiments are required to demonstrate causation.     

Factors influencing the acceptability of energy policies: A test of VBN theory

This paper examines factors influencing the acceptability of energy policies aimed to reduce the emission of CO₂ by households. More specifically, it is studied to what extent the value–belief–norm theory of environmentalism (VBN theory; Stern, [(2000). Toward a coherent theory of environmentally significant behavior. Journal of Social Issues, 56(3), 407–424.]) is successful in explaining acceptability judgements. In contrast to previous studies, we test the full VBN theory. A questionnaire study was conducted among 112 Dutch respondents. Results confirmed the causal order of the variables in VBN theory, moving from relative stable general values to beliefs about human–environment relations, which in turn affect behaviour specific beliefs and norms, and acceptability judgements, respectively. As expected, all variables were significantly related to the next variable in the causal chain. Biospheric values were also significantly related to feelings of moral obligation to reduce household energy consumption when intermediate variables were controlled for. Furthermore, as hypothesized, personal norms mediated the relationship between AR and acceptability judgements, AR beliefs mediated the relationship between AC beliefs and personal norms, AC beliefs mediated the relationship between NEP and AR beliefs, and NEP mediated the relationship between values and AC beliefs.
