This study examines how people make moral judgments about individual efforts to reduce environmental impact. Past research suggests morality is an important driver of such efforts. But it is not known empirically whether people interpret individual-level environmental practices and impact as moral issues. Through analyses of 64 semi-structured interviews, we identify two conditions under which environmental practices and impact influence moral judgments. First, environmental impact must be part of the evaluator's moral culture. We complement and extend existing literature by demonstrating that liberals are more likely than conservatives to make moral evaluations of individual efforts to reduce environmental impact. Second, the evaluator must view the actor as behaving intentionally. People perceive high-income actors as more likely than low-income actors to intentionally reduce environmental impact and, accordingly, view high-income people engaged in green practices as more moral. We confirm the effects of environmental practices and income on the moral judgments that liberals and conservatives make using an online vignette experiment. The experiment was conducted with a nationally-representative sample of US households through NSF's Time-Sharing Experiments in the Social Sciences (TESS). We conclude by discussing implications for research on ethical consumption and politically-polarized views on environmental protection.

这项研究探讨了人们如何对减少环境影响的个人努力做出道德判断。过去的研究表明，道德是这种努力的重要推动力。但是，从经验上还不知道人们是否将个人层面的环境实践和影响解释为道德问题。通过对64个半结构化访谈的分析，我们确定了环境实践和影响会影响道德判断的两个条件。首先，环境影响必须成为评估者道德文化的一部分。我们通过证明自由主义者比保守主义者更有可能对减少环境影响的个人努力进行道德评估来补充和扩展现有文献。其次，评估者必须认为参与者是故意的。人们认为高收入参与者比低收入参与者更有可能故意减少对环境的影响，因此，人们将从事绿色实践的高收入人士视为更道德。我们使用在线插图实验来确认环境实践和收入对自由主义者和保守主义者做出的道德判断的影响。该实验是通过NSF的社会科学分时实验（TESS）对美国家庭的全国代表性样本进行的。最后，我们讨论了对道德消费研究的意义以及对环境保护的政治两极化观点。我们使用在线插图实验来确认环境实践和收入对自由主义者和保守主义者做出的道德判断的影响。该实验是通过NSF的社会科学分时实验（TESS）对美国家庭的全国代表性样本进行的。最后，我们讨论了对道德消费研究的意义以及对环境保护的政治两极化观点。我们使用在线插图实验来确认环境实践和收入对自由主义者和保守主义者做出的道德判断的影响。该实验是通过NSF的社会科学分时实验（TESS）对美国家庭的全国代表性样本进行的。最后，我们讨论了对道德消费研究的意义以及对环境保护的政治两极化观点。
