In the context of complying with the Corporate Sustainability Reporting Directive (CSRD), this study looks at how stakeholder relationships and brand image are affected by sustainability communication from energy companies. Key people from Swedish energy companies have been interviewed and the results show that businesses place a high priority on incorporating social and environmental concerns into their daily operations. Clear CSR communication strengthens brand reputation by improving interaction with internal and external stakeholders, even in the face of economic difficulties. More restrictive laws, like the Green Claim directive, force businesses to enhance their environmental performance and communicate differently, which boosts their credibility. But there are still issues, such as resource limitations and administrative responsibilities. It is believed that these changes are essential to building customer confidence and achieving environmental objectives. The research highlights the intricate relationship that shapes the strategies of energy companies between CSR, stakeholder involvement, and regulatory compliance. In a market that is changing quickly, it highlights how crucial it is to maintain long-term sustainability and stakeholder trust through open communication and proactive regulatory change adaption.
