Abstract: The article is devoted to a new tool of Russian legislation and law enforcement practice – the taxonomy of "sustainable development" and "green" projects. The subject of the study is the understanding of the prerequisites for the adoption and regulatory content of the taxonomy, determining its significance for the development of legal regulation in the light of the concept of sustainable development, as well as its practical value for increasing investments in "green" and "sustainable" infrastructure, improving social and environmental indicators of the population. The relevance of the study is related to the lack of precisely the normative tools for the qualification of "sustainable development" projects, "green" and "climate" projects has long been considered one of the main barriers hindering the development of the Russian market of "sustainable" and "green" financing, as well as increasing demands for streamlining approaches to such projects.
The main research methods were general scientific methods - formal-logical, systemic and functional. Special attention is paid to the comparative legal analysis of the taxonomies of Russia, Kazakhstan and China. The Russian taxonomy has laid the regulatory foundation for the market of sustainable, including green financing in the Russian Federation, and has the potential to contribute to the expansion of its scale. And although through its adoption, the fundamental problem of ensuring sustainable development has not been solved in the legal field. Nevertheless, it introduced terminological (conceptual) certainty, reduced the asymmetry of the goals and objectives of legal regulation of investment and environmental relations, which is also an extremely important task of legal regulation. In the absence of clear goal-setting and normative definitions, new legal and economic categories are given different meanings, which negatively affects the emerging regulation of this sphere of relations. Future tasks related to the development of optimal legal structures for regulating relations arising from the preparation and implementation of projects of "sustainable" development and "green" projects will be solved more effectively, largely due to the foundations laid by the Russian taxonomy.

Abstract: Modern international and cross-border relations in the sphere of public-private partnership (PPP) undergo transformations caused by globalization processes, which leads to the amendments in their legal regulation. The impact of non-state actors increases. Although the toolset for influencing cross-border relations in the sphere of PPP retains its legal core, it is being extended by the rules established by non-state actors outside the international and national legal systems, and carry no legal weight. For PPP as a form of interaction between the state and private investment and business structures, such transformations are particularly noticeable and require precise legal qualification. The scientific novelty of this research consists in providing definition in the international legal doctrine to Lex PPPs as the regulator of cross-border relations in the sphere of public-private partnership. Based on the dialectical, logical, and formal-legal methods, assessment is given to the role of international organizations in the formation of Lex PPPs. In conclusion, the author clarifies the role of Lex PPPs within the system of regulators of public-private partnership, namely that it should not expel the legal regulation of cross-border relations in the sphere of public-private partnership; as well as offers to seek for the new forms of correlation between international law and Lex PPPs and their consolidation through the international legal regulation of public-private partnership.

Abstract: The scope of international legal regulation of public-private partnership (PPP) is being expanded due to the extended range of intergovernmental relations and relations involving international organizations of public-private partnership, as well as extension of the scope of international law to cross-border relations regarding PPP. A relatively small number of international conventional rules and legal norms that regulate the relations in the sphere of public-private partnership have not yet been codified in the form of a multilateral international treaty. Gaps in the international legal regulation activate non-formal processes of managing international and cross-border relations in the sphere of public-private partnership with prevalence of the international intergovernmental organizations. The scientific novelty lies in articulation of the problem of formulation and application of the international standards of public-private partnership as the results of such non-formal processes of international rulemaking of international organizations. Using the formal legal and comparative legal methods, generalization and abstraction, the author formulates the definition of international standards of public-private partnership, discloses their content and difference from the international standards in other spheres of international relations, assesses their legal nature, problems and prospects of their formation. It is substantiated that the development of international standards of public-private partnership would be facilitated by establishment of their adoption procedure in the conditions of cooperation of all international organizations that perform a regulatory function in the sphere of public-private partnership.

Abstract: The recognition of public-private partnership as one of the methods for achieving sustainable development goals shifted its regulation to the category of common interests of the states. The subject of this research is the institutional form of international cooperation in the area of public-private partnership, characterized by involvement of multiple international organizations that have regulatory effect upon the relations in this sphere. The results of such impact are quite significant, but at the same time lower than real capacity. Critical assessment along with analysis of the trends and limitations in exercising of regulatory function of international organizations in the area of public-private partnership appear relevant. Application of the methods of comparative analysis, as well as document and social networks analysis, allow forming the conceptual basis for determining the role of international organizations in regulating public-private partnership, problems of their interaction and prospect of future international cooperation in this sphere. The key role of international organizations in the area of public-private partnership consists in influencing the national peacebuilding processes of the states in the area of public-private partnership by unification and harmonization of corresponding legislation and facilitating the process of creating the customary rules of international law in the sphere of public-private partnership. It also implies in transformation of the concept of public-private partnership. The results of regulatory effect of international organizations with regards to public-private partnership are not necessarily identical, as the functions of international organizations on regulating public-private partnership have its limitations, substantiated either by the objective factors of the development of international cooperation in the area of public-private partnership, or mostly by the provisions of constitutive acts of these organizations. The method of overcoming such issues can become the transformation of regulatory function of international organizations and modification of the instruments for its implementation or creation of new ones.
