Climate change presents significant challenges for legal systems, as effective regulation of adaptation measures is necessary. The lack of a unified approach to the legal framework for adaptation mechanisms complicates the implementation of state policy in this area. This study aims to analyze the legal mechanisms for adapting to climate change and their compliance with international standards. The methodology encompasses a systematic analysis of national and international legislation, a comparative examination of the legal approaches employed by different countries, and legal modeling to evaluate the effectiveness of existing mechanisms. Doctrinal analysis and legal hermeneutics methods were employed. The results of the study indicate the fragmentation of normative-legal support for climate change adaptation. It has been established that the implementation of effective adaptation measures requires harmonization of national legislation with international obligations and the expansion of the powers of local authorities. It is recommended to develop a comprehensive law on climate change adaptation that takes into account European approaches and ensures a clear mechanism for the implementation of adaptation measures.
