This thesis explores the right to a clean, healthy and sustainable environment in the Anthropocene. Historically, the right to a healthy environment has been constructed through “greening” other human rights, due to the severe impacts of environmental degradation on human-wellbeing. In 2022, however, it was recognized as a stand-alone human right by the United Nations General Assembly (UNGA). Based on constructivism, Eco-Marxism and Green Political Theory this thesis analyzes relevant UN and EU legislations. It focuses on UN Resolution 76/300 to analyse the design of a right to a healthy environment and on the EU’s Common Fisheries Policy (CFP) to evaluate the governance of marine resource exploitation. Conducted through an ideological critique, the investigation reveals that both documents ground their ideas and values on the environment’s contribution to growth and wealth accumulation. The design of the human right to a healthy environment is constrained by its alignment with Agenda 2030 and the pursuit of sustainable development, due to the capitalist framework they are constructed in. This framing limits the potential of the upcoming revision of the CFP to prioritizing exploitation and capital gain over conservation and protection. Ultimately, the thesis argues that without a paradigm-shift towards a post-capitalist construction of policies, the human right to a healthy environment in the Anthropocene remains restricted in its transformative capacity.
