The Critical Challenge of Climate Change for Psychology

Abstract

For many societies, the prime political strategy for mitigating climate change has been to improve the efficiency of technology (e.g., cars, light bulbs, and refrigerators). However, World Bank data suggest that the per-capita energy consumption of societies is leveling off rather than falling. Thus, all efficiency gains are apparently eaten up by rebound. In our psychological account of this ubiquitous rebound phenomenon, we argue that individual consumption is genuinely rational (i.e., benefit-oriented) and grounded in an unlimited number of personal ends (i.e., goals and desires). Behavior and technology – the latter as an amplifier of individual behavior – are means for satisfying personal ends. Predictably, any gains in efficiency as evidenced by savings of time and/or money will be reinvested in further as-yet-unmet personal ends of individuals. Consequently, rebound is the norm and not the exception. The challenge to psychologists is thus, as we argue in this article, to motivate individuals to act comparatively more irrationally (by generally forgoing personal benefits), and by doing so, to eventually reduce the overall energy consumption of societies. Only when people are intrinsically motivated to forgo commodities, convenience, and other personal benefits can rebound be avoided.

Outcome expectancy: A key factor to understanding childhood exposure to nature and children's pro-environmental behavior

“…Human behavior is largely responsible for the environmental issues we face today (Cook et al, 2013), requiring a deeper understanding of the substance and etiology of pro-environmental behaviors (Gifford, 2011;Otto, Kaiser, & Arnold, 2014;Schultz & Kaiser, 2012). Pro-environmental behavior refers to actions that contribute to the sustainability of nature (Schultz & Kaiser, 2012).…”

Toward an Integrated Approach to Environmental and Prosocial Education

“…When examining the responses to this troubling reality, as educators, we are troubled, because hardly any response is based on educating people, even though environmental education seems to be necessary for sustainable development [2,3]. Most of the serious endeavors that aim to tackle environmental problems today are primarily technological.…”

Capturing the Environmental Impact of Individual Lifestyles: Evidence of the Criterion Validity of the General Ecological Behavior Scale

“…Keywords behavioral assessment, conservation (ecological behavior), test validity, affluence, energy consumption Many environmental psychologists recognize the need to promote more ecologically sustainable patterns of behavior or lifestyles (e.g., Howard, 2000;Otto, Kaiser, & Arnold, 2014). It appears, though, that what people choose to do to reduce their environmental impact often does not correspond well with what research in industrial ecology suggests they should be doing (e.g., Gatersleben, Steg, & Vlek, 2002;Stern, 2000b).…”
