| Summary/Abstract |
Energy labels with compact information on the energy use of appliances have been adopted worldwide to encourage consumers to make informed investment decisions. This study examines whether communicating environmental emissions (CO2 and air pollutant emissions) on energy labels can increase the preferences for energy-efficient appliances, with a specific focus on the role of individual psychological traits. A survey with decision tasks was conducted among the adult population in the Netherlands. Results show that information on environmental emissions does not increase the intention to invest in energy-efficiency, while energy-saving attitudes and habits do. Nevertheless, presenting information on CO2 emissions as well as combined CO2 and air pollutant emissions on energy labels can increase the preferences for energy-efficient appliances among individuals with relatively strong postmaterialist values. Information on CO2 emissions also increases the preferences of individuals with strong environmental concerns. However, no significant effects are found for information on air pollutant emissions. Also, personal experience of environmental degradation was not found to affect the effectiveness of the tested information interventions. Finally, we discuss the role of attention and type of decision situation for the processing of emissions information on energy labels. Our findings provide insights for improving information display on energy labels and energy education.
