The article examines the approaches used by the Eurasian Economic Union (EAEU) member states to implementing the climate agenda. The EAEU countries are pursuing policies aimed at developing national climate strategies. Additionally, they are working on the formulation of common approaches for establishing a unified mechanism, which is to be created through the convergence and harmonization of national legislations. However, the approaches of the EAEU countries are significantly influenced by various factors, including substantial disparities in the economic potential of the member states and their independent economic policies. Furthermore, environmental challenges among the EAEU countries also impact the approaches of individual states within the integration association. The increased attention to the issue of climate change is explained by its growing negative impact on the socioeconomic development of various states and on international relations. Climate change adversely affects millions of lives in many countries worldwide. On a global scale, climate change is causing irreparable damage to the planet’s ecosystem. It affects a significant number of spheres and, primarily, issues related to water resources and food security. Consequently, climate change has become an integral part of world politics, increasingly influencing international relations. At the same time, the set of measures proposed by countries to minimize the negative impact of climate change has not been put into practice. This problem is fully evident within the EAEU as well. The article concludes that the EAEU countries must develop unified approaches that will reduce their impact on climate and thereby enable the fulfillment of the climate agenda’s goals. The tasks for the EAEU countries include implementing low-carbon projects and refraining from introducing trade barriers associated with climate regulation.
