In doing so, long-term behavioral changes and positive spillover effects may be achieved and negative spillover may be alleviated. Taking into account this twofold perspective on sustainable consumption, we designed an intervention program for the promotion of sustainable consumption in terms of energy efficiency at the workplace. The program evaluation covered impact-related indicators in terms of metered energy consumption data, and intent-related indicators in terms of a scale referring to the general motivation to save energy at the workplace. The intervention program showed positive outcomes for both kinds of indicators while the relationships between the indicators were moderate only.", }
