Electric cars as a path to sustainable travel behaviour: Insights from Nord-Jæren
研究挪威Nord-Jæren地区1223人的出行数据，发现环保信念会因汽车便利性而促进电动汽车使用，但未必减少总车行，需同时改善替代交通并限制汽车。
This study examines whether promoting electric cars (EVs) to achieve greener mobility undermines the efforts to reduce car use. It specifically explores the concept of moral licensing, wherein individuals use EVs as a way to feel good about their environmental impact while continuing to drive. The study uses travel data (n = 1223) from Nord-Jæren, Norway, to develop a Structural Equation Model (SEM) that explores the relationship between environmental beliefs, attitudes, and travel behaviour (i.e., use of conventional car, electric car, bus, and bicycle). The results confirm that pro-environmental beliefs have a “spillover effect” on EV use due to existing car attitudes. The relative convenience of the car over alternative options has been found to be the most important mitigating factor in the influence of environmental beliefs on behaviour. Consequently, to reduce car use and promote more sustainable travel options, it is essential to simultaneously improve these alternatives while restricting car traffic.
