The climate agenda has gathered extraordinary pace due to Greta Thunberg and other autistic environmentalists. Thunberg's autism is widely used to explain and celebrate, but also diminish and denigrate, her activism. However, despite speculation linking autism, pro-environmental action, and climate change belief, there is neither psychological theory nor empirical evidence on this topic. We therefore considered theoretical reasons for and against this potential association, and examined whether autistic traits were positively, if at all, linked to pro-environmental attitudes and behaviors, and climate change belief. In three preregistered studies (N = 2288), including nationally representative samples and well-powered frequentist and Bayesian analyses, we found substantial evidence that autistic traits were associated with engagement in fewer pro-environmental behaviors. Further, autistic traits were neither predictive of pro-environmental attitudes nor climate change belief. We conclude that, irrespective of environmental attitudes or climate change belief, autism and mental health conditions may present barriers for pro-environmental action. Suggestions for understanding the psychological factors underlying climate action and a more inclusive environmental agenda are discussed.

由于 Greta Thunberg 和其他自闭症环保主义者，气候议程已经加快了步伐。Thunberg 的自闭症被广泛用于解释和庆祝，但也削弱和诋毁她的激进主义。然而，尽管推测将自闭症、环保行动和气候变化信念联系起来，但关于这个主题既没有心理学理论也没有经验证据。因此，我们考虑了支持和反对这种潜在关联的理论原因，并检查了自闭症特征是否与亲环境态度和行为以及气候变化信念有积极联系（如果有的话）。在三项预先注册的研究中（N = 2288），包括具有全国代表性的样本和强有力的常客和贝叶斯分析，我们发现大量证据表明自闭症特征与较少的亲环境行为有关。此外，自闭症特征既不能预测亲环境态度，也不能预测气候变化信念。我们得出的结论是，无论环境态度或气候变化信念如何，自闭症和心理健康状况都可能成为环保行动的障碍。讨论了理解气候行动背后的心理因素和更具包容性的环境议程的建议。
