The paper deals with the climate agenda in the Eurasian Economic Union. Particularly, it analyzes the current stage of implementation of green finance principles in the member states of the EAEU. In the article, the authors identify the key problems for the social and economic development of the member states in the context of the global environmental transformation, and examine most relevant policy documents to address climate challenges. At present, all EAEU member states are committed to the Paris Agreement. They are developing framework for sustainable finance system at the national levels, and made efforts to introduce green finance principles within the organization. However, for the most part, little progress has been made. The authors stress that different timelines and trajectories will hinder the EAEU to achieve carbon neutrality, so, in the first place, the issue of the contingency of national climate policies within the Union should be addressed
