The integration of environmental, social, and governance (ESG) principles into financial decision-making systems is examined in this study as a significant element in ensuring the long-term competitiveness and sustainable development of entrepreneurship in a constantly changing world. Companies that actively integrate ESG factors into their operations gain numerous advantages, including improved operational efficiency, reduced risks, enhanced reputation, and attraction of highly qualified specialists. Conversely, organizations that neglect ESG aspects face increasing reputational, financial, and regulatory risks. Therefore, emphasizing the ESG concept is not merely an ethical imperative but a strategically important condition for ensuring successful and long-term business development. The study aims to analyze the interdependence between ESG factors and companies' financial sustainability, as well as to develop specific recommendations for the effective integration of ESG principles into business strategies and models. Within the scope of the conducted research, the following tasks were accomplished: key interdependencies between the integration of ESG factors and companies' financial sustainability indicators were identified; a comparative analysis of risks and opportunities arising from the application of ESG approaches was performed; practical recommendations for businesses on adapting strategies considering sustainable development principles were formulated. Emphasis is placed on developing tools to enhance the transparency of financial decisions associated with the implementation of ESG initiatives and assessing their impact on organizations' investment attractiveness.
