This paper explores the concept and significance of sustainable finance as a vital tool for addressing environmental, social, and governance (ESG) challenges in the context of global development and post-war economic recovery. The study highlights the evolution of sustainable finance from a niche trend to a core component of investment portfolios, emphasizing the importance of ESG integration in financial systems. Particular attention is paid to distinguishing sustainable finance from related concepts such as green and climate finance, clarifying the broader scope of ESG-driven financial strategies. The paper analyzes key international approaches and policy frameworks, including the European Union’s Strategy for Financing the Transition to a Sustainable Economy, the International Finance Corporation’s performance standards, and the World Bank’s recommendations for developing national taxonomies of sustainable economic activities. The relevance of these frameworks is examined in the context of Ukraine’s post-war reconstruction and transition to a low-carbon, inclusive economy. The purpose of the paper is to systematize approaches to sustainable finance, identify its key components and instruments, and justify the potential of applying these approaches in the recovery and modernization of the Ukrainian economy in accordance with international sustainability standards. The study outlines the importance of ESG reforms for attracting private capital, increasing investment transparency, and aligning national development strategies with global trends. Methodologically, the research employs content analysis of international policy documents and analytical reports, as well as a comparative evaluation of investment scenarios with and without ESG integration. The findings support the conclusion that sustainable finance offers a strategic opportunity not only to rebuild critical infrastructure but also to create a resilient and competitive economy. The paper underscores the need for institutional support, regulatory adaptation, and active cooperation between the public and private sectors to maximize the benefits of sustainable financial practices in Ukraine’s recovery efforts.
