International climate law is often represented as a set of rules and institutions that scholars have tracked for nearly 30 years, whether to document them, assess their effectiveness, or prescribe reforms. This article, in contrast, adopts a critical perspective to uncover the everyday life of international climate law. From this viewpoint, international climate law is a purposive endeavour that is grounded in the small places where people create and live out the law. ‘International climate lawyers’ are among those who produce the law within these sites, and they propagate international climate law across multiple institutions. Using legal-ethnographic description, the article shows how lawyers operationalize the law in the United Nations climate regime, World Bank, and international human rights system. In each case, lawyers effect some overlapping aspirations for the law as well as legal techniques, but they also adapt their practices to the places where they work. In the process, they simultaneously build and diversify their professional community. Both in their field and community then, lawyers generate heterogeneity and homogeneity through the proliferation of international climate law. They do so on multiple registers, in terms of diverging ethical commitments, multivalent legal forms, and relative authority to speak the law, notably between institutions and the Global North and Global South. If lawyers reproduce sameness and difference in international climate law, moreover, this article suggests they may reify analogous traits in the broader field of international law, including persisting power relations.

关于成为同伴和陌生人：律师与国际气候法的产生

国际气候法通常表现为学者们追踪了近 30 年的一套规则和制度，无论是记录它们、评估其有效性还是规定改革。相比之下，本文采用批判的视角来揭示国际气候法的日常生活。从这个角度来看，国际气候法是一项有目的的努力，其基础是人们创造和实施法律的小地方。“国际气候律师”是在这些网站内制定法律的人之一，他们在多个机构中宣传国际气候法。本文使用法律民族志描述，展示了律师如何在联合国气候制度、世界银行和国际人权体系中实施法律。在每种情况下，律师对法律和法律技巧产生了一些重叠的愿望，但他们也使他们的实践适应他们工作的地方。在此过程中，他们同时建立和多样化他们的专业社区。当时，在他们的领域和社区中，律师通过国际气候法的扩散产生了异质性和同质性。他们在多个登记册上这样做，就不同的道德承诺、多价的法律形式和相关的法律发言权而言，特别是在机构与全球北方和全球南方之间。此外，如果律师在国际气候法中重现相同和差异，本文建议他们可以在更广泛的国际法领域具体化类似特征，包括持续的权力关系。
