Research on global climate change governance is no longer primarily concerned with the international legal regime, state practice and its outcomes, but rather scrutinizes the intricate interactions between the public and the private in governing climate change. This broad trend has also taken center stage within the pages of INEA. Two decades after its establishment, we sketch the main theoretical debates, conceptual innovations and empirical findings on global climate change governance and survey the new generation of climate governance scholarship. In more detail, we sketch how climate governance research has developed into three innovative sub-debates, building on important conceptualizations and critical inquiries of earlier debates. Our aim is not so much to provide an all-encompassing assessment of global climate change governance scholarship in 2022, but rather to illustrate in what important ways current research is different from research in the early phase of INEA, and what we have learned in the process. First, we discuss scholarship on the bottom-up nature of climate governance, developing from earlier ideas on agency beyond the state and the transnationalization of governance arenas. Second, we review contributions that have more systematically engaged with the concept of governance architectures, resulting in a stimulating new academic debate on the characteristics of complex governance systems and the consequences of governance complexity and fragmentation. Third, we note a distinct normative turn in global environmental scholarship in general and global climate governance in particular, associated with question of access, accountability, allocation, fairness, justice and legitimacy. The assessment of each of these debates is centered around questions of effective and legitimate climate governance to counter the climate emergency. Finally, as a way of concluding, we critically reflect on our own scholarly shortcomings and suggest a modest remedy.

全球气候变化治理研究不再主要关注国际法律制度、国家实践及其结果，而是审视公众与私人在治理气候变化中的错综复杂的互动。这种广泛的趋势也在INEA的页面中占据了中心位置。在其成立 20 年后，我们概述了全球气候变化治理的主要理论争论、概念创新和实证结果，并对新一代气候治理学术进行了调查。更详细地，我们概述了气候治理研究如何发展为三个创新的子辩论，建立在早期辩论的重要概念和批判性调查的基础上。我们的目标与其说是对 2022 年的全球气候变化治理学术进行全面评估，不如说是为了说明当前的研究与 INEA 早期阶段的研究在哪些重要方面有所不同，以及我们在过程。首先，我们讨论关于气候治理自下而上性质的学术研究，从早期关于超越国家的机构和治理领域跨国化的观点发展而来。其次，我们回顾了更系统地涉及治理架构概念的贡献，从而引发了关于复杂治理系统特征以及治理复杂性和碎片化后果的新学术辩论。第三，我们注意到，全球环境学术特别是全球气候治理出现了明显的规范转变，与准入、问责、分配、公平、正义和合法性问题有关。对每场辩论的评估都围绕着有效和合法的气候治理问题，以应对气候紧急情况。最后，作为总结的一种方式，我们批判性地反思了我们自己的学术缺陷，并提出了一个适度的补救措施。
