The subject of the study is the development of the green bond market after the start of a special military operation. The relevance of this article is due to the objective need to find opportunities to smooth out the negative effects of international sanctions on the green bond market, including through the use of special measures of state support and stimulation of the market for a period of at least adaptation to new conditions of existence. The purpose of the work is to search and evaluate opportunities for the development of the Russian green bond market in the conditions of economic war with the collective West and partial external isolation of the Russian economy. To achieve it, measures are justified to support the Russian green bond market for the period of structural transformation of the Russian economy and the creation of a new financial infrastructure with the external sector. As a result of the application of methods of analysis and synthesis, systematization, classification and categorization of information, it was revealed that out of 46 stock exchanges around the world on which green bonds are traded, only 12 exchanges are located on the territory of friendly countries. After the Russian market was cut off from the external sector, Russian issuers no longer have the opportunity to use the services of international consulting companies in the field of evaluation, verification, audit, etc., which significantly complicates access to any foreign capital markets. Conclusions are drawn that additional measures of state support of the Russian green bond market are necessary for the transition period. Substantial efforts are required to restore a positive investment climate in the Russian financial market, in which the central role belongs to the state through the use of the reserves of the NWF and the conduct of an appropriate information campaign, which will smooth out the severity of the problems of the transition period.
