Abstract Successful climate change mitigation and adaptation depend on the public's trust in experts. Gaining a deeper understanding of how trust in certain actors influences individuals' mitigation and adaptation behaviours is, therefore, key. We present results of a meta-analysis that examines the role of trust in institutions, scientists, industry, environmental groups and people in general, in relation to different climate-friendly behaviours. We further categorise behaviours into ‘public’ and ‘private’ behaviours and conduct meta-regressions to see whether these categories moderate overall effect sizes. Analysing 141 correlations from 51 studies (46 articles), we find that trust in scientists and trust in environmental groups strongly correlate with climate-friendly behaviours. Meta-regressions further show that trust in institutions is moderately correlated with public behaviours, but only weakly with private behaviours, while associations with trust in industry and general trust measures are weak. We discuss the implications of these findings for climate scientists and how experts can potentially increase trust levels to foster engagement in climate-friendly behaviours.

信任对减缓气候变化和适应行为的作用：荟萃分析

摘要 成功减缓和适应气候变化取决于公众对专家的信任。因此，深入了解对某些行为者的信任如何影响个人的缓解和适应行为是关键。我们展示了一项荟萃分析的结果，该分析考察了信任对机构、科学家、行业、环保团体和一般人的作用，与不同的气候友好行为相关。我们进一步将行为分为“公共”和“私人”行为，并进行元回归以查看这些类别是否会调节整体效应大小。分析来自 51 项研究（46 篇文章）的 141 项相关性，我们发现对科学家的信任和对环保团体的信任与气候友好行为密切相关。元回归进一步表明，对机构的信任与公共行为适度相关，但与私人行为的相关性较弱，而与行业信任和一般信任措施的相关性较弱。我们讨论了这些发现对气候科学家的影响，以及专家如何潜在地提高信任水平以促进气候友好行为的参与。
