Eco-driving can be an effective strategy to save fuel and reduce CO2 emissions on the road. In the current study, we reason that personal norms are important predictors of eco-driving, and that they are activated when people are aware of environmental problems caused by behavior (problem awareness) and believe that they can contribute to the solution of the problem by changing behavior (outcome efficacy). Extending previous research, we aim at testing two antecedents of this norm activation process: values and environmental knowledge. Results revealed that in comparison with knowledge, values—in particular biospheric values—were strongly associated with the intention to eco-drive by being highly related to awareness of problems caused by car use, which in turn was associated with stronger outcome efficacy beliefs and personal norms for eco-driving. Findings indicate that values are more likely to be a motivational force for pro-environmental intentions than is environmental knowledge.

价值观与环境知识作为激活生态驾驶个人规范过程的触发器

环保驾驶可以成为节省燃料和减少道路二氧化碳排放的有效策略。在目前的研究中，我们认为个人规范是生态驾驶的重要预测因素，当人们意识到由行为引起的环境问题（问题意识）并相信他们可以通过以下方式解决问题时，它们就会被激活改变行为（结果效力）。扩展之前的研究，我们的目标是测试这个规范激活过程的两个前提：价值观和环境知识。结果显示，与知识相比，价值观——尤其是生物圈价值观——与生态驱动的意图密切相关，因为它与对汽车使用引起的问题的认识高度相关，而这反过来又与更强的结果功效信念和个人生态驾驶规范。
