The article explores the integration of environmental management standards into business strategies as a key driver of sustainable development and the green economy. It begins with a discussion of the conceptual framework of sustainable development, emphasizing the balance between economic growth, environmental protection, and social inclusion. The knowledge gap identified lies in the insufficient understanding of how international ecological standards—such as ISO 14001, EMAS, GRI, and IFRS S1/S2—contribute to systemic corporate transformation and long-term competitiveness. The study applies an analytical method based on a review of international reports, sustainability frameworks, and empirical studies from 2023–2025, focusing on the implementation of environmental standards in corporate governance. Findings reveal that ISO 14001 and EMAS improve operational efficiency, reduce resource use, and enhance transparency, while GRI and IFRS S1/S2 ensure standardized sustainability disclosure and strengthen stakeholder trust. The introduction of IFRS S2 guidance in 2025 and national ESG frameworks in Russia and Uzbekistan demonstrates the global shift toward harmonized reporting and green investment strategies. Results confirm that adherence to environmental standards positively affects financial stability, investor confidence, and access to green capital. The article concludes that environmental management systems are not only compliance tools but also strategic levers for innovation and competitiveness. The implication is that governments and corporations must jointly develop policies that integrate ESG metrics, encourage sustainable finance, and accelerate the transition toward low-carbon, resource-efficient economies.
