In the modern world, normative regulation is one of the key measures to improve the environmental crisis situation. At the international level, such regulation is carried out by both international organizations and interstate associations. This research examines the BRICS normative acts that were adopted between 2009 and 2025, as outcomes of this interstate association in the context of environmental aspects. The relevance of the research stems from the fact that the majority of current studies tend to focus only on certain environmental aspects of international treaties and national laws of the BRICS countries. This research, however, presents a concept of the BRICS normative space as a set of BRICS norms, which is further divided into official and unofficial subsets based on the status of the norm-makers. These norms are analyzed to assess their scope and coverage of environmental aspects. The main findings of the research indicate that the environmental aspects are covered in the norms of both subsets from different perspectives, including through the expression of opinions, intentions, recommendations, action plans, and calls. This research can contribute to a better understanding of the nature and structure of the BRICS environmental norms.
