The study by Poortinga, Steg, and Vlek (2004) explores the role of values in household energy use and environmental behavior. Using the concept of quality of life (QOL), 22 QOL aspects were summarized into seven value dimensions. These dimensions, along with general and specific environmental concern, significantly explained policy support for environmental regulation and market strategies, as well as the acceptability of energy-saving measures. Home and transport energy use were primarily related to sociodemographic variables like income and household size. The study highlights the importance of distinguishing between different types of environmental impact and intent. It also shows that values alone may not fully explain all environmental behaviors. The hierarchical model proposed by Stern et al. (1995) was used to examine the relationship between values and environmental behavior. The model links values to environmental behavior through mediating variables. The study found that environmental concern and specific beliefs, such as concern about global warming, were related to various types of environmental behavior. The results indicate that different aspects of environmental impact and intent are influenced by distinct variables. The study also shows that household energy use is primarily related to sociodemographic variables, while attitudinal variables explain a smaller portion of the variance. The findings suggest that environmental behavior is influenced by both motivational and contextual factors. The study concludes that a purely attitudinal model may be too limited to explain environmental behavior, and that contextual factors should be considered in future research.The study by Poortinga, Steg, and Vlek (2004) explores the role of values in household energy use and environmental behavior.
