Abstract
The paper examines contemporary issues of developing technological and environmental sovereignty in the context of the transformation of the global climate agenda and increasing geoeconomic competition. Particular attention is given to the relationship between climate policy, technological development and economic sustainability of states within the Eurasian economic space. It is emphasized that achieving environmental goals, including decarbonization and carbon neutrality, is impossible without developing our own technological base and reducing dependence on external suppliers of critical solutions. The authors analyze the institutional and legal mechanisms for implementing climate policy in the EAEU countries, identifying differences in the level of technological support and the degree of involvement of international partners. It is noted that the climate agenda is gradually moving beyond purely environmental issues and becoming a factor in the structural modernization of the economy. The paper substantiates the thesis that technological sovereignty is a key condition for the effective implementation of climate strategy and ensuring the strategic autonomy of states. A conclusion was made regarding the need to coordinate the efforts of the EAEU countries in the development of low-carbon technologies, the unification of standards, and the formation of a joint innovation infrastructure as the basis for the sustainable development of the region.
