SUSTAINABLE SUPPLY CHAINS AS A COMPETITIVE FACTOR IN INTERNATIONAL MARKETING

The aim of this paper is to explore how sustainable supply chains contribute to enhancing the competitiveness of companies in international markets, particularly through the integration of sustainability principles into marketing strategies and global business practices. Building upon contemporary theoretical approaches to international marketing, circular economy, and corporate sustainability, the study applies a comparative and synthetic analysis of secondary sources, complemented by case studies of global companies that have implemented sustainable supply chain models. The methodological framework includes qualitative analysis of strategic documents, corporate social responsibility reports, and market performance indicators, with the objective of identifying the relationship between sustainability, reputation, and market position. The research results indicate that companies actively developing sustainable supply chains achieve long-term competitive advantage through increased consumer trust, reduced resource costs, and stronger relationships with partners across the value chain. Sustainable practices in procurement, logistics, and distribution have become a core element of marketing strategy, as they contribute to building brands perceived as responsible, innovative, and reliable. The conclusions confirm that sustainability is no longer an additional value but a strategic imperative for competitiveness in international marketing. The paper recommends integrating green logistics, digital tools for supply chain monitoring, and standardized sustainability criteria into all stages of business operations. The additional contribution of this research lies in the development of a conceptual model linking sustainable practices with the elements of the international marketing mix, providing both a theoretical framework and practical guidelines for companies striving for global competitiveness based on sustainable development.
