We live in the Anthropocene – the Age of Humans – characterized by dangerous environmental degradation, demanding urgent and adequate international environmental governance (IEG). Yet, IR scholarship problematizes the shortcomings of current IEG, demonstrating its failure to fight environmental degradation. During the Covid-19 pandemic, the UNDP published the 2020 Human Development Report titled ‘The next frontier – Human Development in the Anthropocene’. A preliminary reading suggests a shift towards ecocentric governance. Inspired by this development, this study situates itself within the literature on Adaptive Governance in the Anthropocene. It explores if IEG is indeed adopting ecocentrism, thereby adapting to the conditions and demands of the 21st century. Complementing UNDP with two additional cases (UNEP and WHO), this research attempts to provide an updated understanding of the state of IEG in 2020/21 through qualitative content analysis of flagship reports. Green Theory and scholarship on IEG and the Anthropocene will be utilized to construct the research design, as well as to assess the content and meaning of the results. The research findings suggest that UNDP, UNEP, and WHO adopt ecocentrism norms, albeit with certain gradations present. This study attempts to complement the governance literature and take a stand regarding the status of IR in the Anthropocene.
