There is a gap between the public awareness of the environmental impact of cars and eco-friendly car purchases. The European Commission Directorate-General for Climate Action (DG Clima) and the London School of Economics conducted an an online experiment in which participants were exposed to different sets of information about the emissions of the same car and then asked how environmentally-friendly they viewed the vehicle. The effects found in the experiments were not consistent, nor did they provide a clear picture about what impact was had. Information about fuel economy led to more environmentally-friendly preferences thanemissions-related information.
