Design/methodology/approach The study adopts a qualitative single-case design, focusing on a corporate energy services company (Interconexión Eléctrica S.A.) operating in volatile, uncertain and turbulent environments. Findings The findings indicate that integrating sustainability into the corporate strategy enables subsidiaries to effectively meet global requirements, considering internal and external pressures. This integration also fosters the development of unique capabilities and the internalization of standards, addressing liabilities in foreign markets, thus providing a competitive advantage and safeguarding corporate legitimacy among stakeholders. Originality/value This research contributes to the international business literature by providing insights into strategy development and implementation in EMNEs.

The study also offers guidance for emerging market companies on developing sustainability strategies and transferring them to subsidiaries operating in complex institutional environments. Furthermore, the research provides a rationale for governments and civil society organizations on why firms are committed to sustainability, highlighting its positive impact on firm’s competitiveness and survival in international markets.
