Our Transformation Journey
TBS is undergoing a bold transformation to ensure long-term sustainability and resilience. We are gradually divesting from coal and reinvesting in future-forward businesses that accelerate the energy transition. This journey positions us as an active driver of Indonesia’s low-carbon economy while creating shared value for communities, partners, and stakeholders.

There are two approaches to achieve carbon neutrality in 2030:
- (i) accelerating the decarbonization of our assets.
- (ii) Throughout 2023, we have continued to explore innovative approaches to achieving TBS2030. Notably, these changes incorporate a heightened focus on waste management.
