Climate change has intensified tensions surrounding international environmental law, requiring a reinterpretation of its principles and governance mechanisms. This study examines how literature published between 2014 and 2024 has conceptualized the transformation of international environmental law, particularly in relation to the evolution of legal principles, methodological trends, regulatory gaps, and thematic research patterns. A B-SLR approach is used, integrating bibliometric analysis and systematic review of a corpus of articles indexed in Web of Science and Scopus, selected using the PRISMA protocol and a semantic classification system based on Natural Language Processing. The findings reveal sustained growth in scientific output and an intellectual structure configured around climate justice, polycentric governance, green economy, and human rights. Qualitative analysis shows a transition towards more flexible and adaptive legal models, accompanied by the expansion of climate litigation and the use of human rights frameworks to reinforce state obligations. However, critical issues related to regulatory fragmentation, dependence on soft law, and institutional weakness persist. Overall, international environmental law is undergoing a profound and still incomplete process of reconfiguration in the face of the accelerating climate crisis.
