Abstract

Although psychologists have investigated a great variety of intervention strategies, we still lack a theoretical framework which could be used to inform an optimal selection and combination of strategies to reduce energy consumption. In the paper at hand, an integrated influence model of pro-environmental behaviour is introduced and used for the development of a tailored intervention to change energy use behaviour in a work context. The target group consisted of staff members of a German university. Prior to intervention planning, motives and cognitive variables concerning energy use were recorded in two randomly chosen sub-samples of the target group (n = 99; n = 87). Intervention techniques were selected and designed in consideration of model variables. Intervention impact was evaluated on the basis of consumption values, behavioural indicators, and self-report (N = 966). Implications for further intervention planning are discussed.
