ABSTRACT: Green transformation in the banking sector has become a top priority amidst increasing global awareness of sustainability. This research focuses on the implementation of green banking strategies at PT BPD Kaltim Kaltara (Bankaltimtara) as an effort to support environmental sustainability while improving the company’s financial performance. Using a descriptive qualitative approach, this research examines various sustainability programmes that have been implemented by Bankaltimtara, such as energy efficiency, waste management, and financial literacy promotion. The results show that the implementation of green banking principles not only helps reduce environmental impacts but also improves the bank’s profitability and competitiveness. In addition, this strategy strengthens relationships with stakeholders, including customers, communities, and regulators. However, challenges remain, such as high implementation costs and a gap in awareness of green banking products. This research recommends strengthening regulations, improving customer education, and green product innovation as strategic steps to optimise green banking implementation. The findings support the importance of green transformation as a long-term investment for the sustainability of the banking business.
