Climate justice is increasingly prominent in climate change communication and advocacy but little is known about public understanding of the concept or how widely it resonates with different groups. In our global survey of 5,627 adults in 11 countries spanning the global north and south, most participants (66.2%) had never heard of climate justice. Nonetheless, endorsement of climate justice beliefs was widespread (for example, acknowledging the disproportionate impact of climate change on poor people and the underpinning roles of capitalism and colonialism in the climate crisis). Climate justice beliefs were also associated with various indices of climate action and policy support. These associations tended to be stronger in countries with high GHG emissions and where social inequality is also more politically salient. The results highlight the value of climate justice as a motive for climate action across diverse geographical contexts.

气候正义在气候变化传播和倡导中越来越突出，但人们对公众对这一概念的理解或它与不同群体的广泛共鸣知之甚少。在我们针对全球南北 11 个国家/地区的 5,627 名成年人进行的全球调查中，大多数参与者 （66.2%） 从未听说过气候正义。尽管如此，气候正义信念得到了广泛的认可（例如，承认气候变化对穷人的不成比例的影响以及资本主义和殖民主义在气候危机中的基础作用）。气候正义信念还与气候行动和政策支持的各种指标有关。在温室气体排放量高且社会不平等在政治上也更为突出的国家，这些关联往往更强。结果突出了气候正义作为不同地理背景下气候行动动机的价值。
