Individual, car-based mobility contributes significantly to worldwide greenhouse gas emissions. Driving style accounts for up to 30% of fuel consumption and manufacturers have implemented technologies such as energy-efficient “eco” driving modes to reduce emissions. Here we report evidence from a field experiment with battery-electric vehicles. Two behavioral interventions, changing the mode's default to on and informing drivers about the frequency of other people's usage of the mode, i.e. providing a descriptive social norm, successfully increased eco mode usage. However, the cars' acceleration and energy consumption remained unaffected due to a behavioral rebound, and were instead predicted by a situational factor, trip distance. While behavioral interventions proved effective, the results suggest that technological interventions aiming to reduce the environmental impacts might focus more strongly on alterations of situational rather than dispositional factors of people or cars.

以汽车为基础的个人出行对全球温室气体排放做出了重大贡献。驾驶风格占燃料消耗的 30%，制造商已实施节能“生态”驾驶模式等技术以减少排放。在这里，我们报告了电池电动汽车现场实验的证据。两种行为干预，将模式的默认设置更改为开启并告知驾驶员其他人使用该模式的频率，即提供描述性的社会规范，成功地增加了生态模式的使用。然而，由于行为反弹，汽车的加速度和能量消耗没有受到影响，而是由情境因素预测，行程距离。虽然行为干预被证明是有效的，
