Corporate sustainability is becoming a significant part of companies' strategic development, promoting efficient resource use, public trust, and competitiveness. The implementation of sustainability principles in management systems helps organisations adapt to evolving regulatory requirements and ESG (Environmental, Social, and Governance) challenges. Integrated management systems can serve as an effective tool for achieving sustainability goals and strengthening a company’s competitiveness. The aim of this paper is to analyse how integrated management systems support the implementation of corporate sustainability by ensuring compliance with ESG requirements and promoting sustainable business practices. The study employs a literature review and qualitative content analysis. Based on theoretical research, the authors identify how integrated management systems contribute to corporate sustainability and how these two concepts interact.
