Transforming our business and the energy landscape—toward a cleaner, more resilient future.
Our Sustainability Journey
Transforming from a conventional energy business into a low-carbon growth platform.

TBS is undergoing a fundamental transformation. As the global energy transition accelerates, we are reshaping our portfolio to align with Indonesia’s climate ambitions while building resilient, future-ready businesses.
Through TBS2030 — Towards a Better Society, we are transitioning away from carbon-intensive assets and investing in scalable solutions that reduce emissions, strengthen communities, and generate long-term economic value.
Sustainability therefore sits at the center of how we operate, invest, and grow—guided by transparent governance, measurable targets, and strong partnerships across the public and private sectors.
Key Overview:
- Carbon neutrality by 2030 through the TBS2030 roadmap
- Portfolio transition toward waste management, renewable energy, and electric mobility
- ESG and climate risk fully integrated into corporate strategy and enterprise risk management
- Annual sustainability reporting aligned with leading global frameworks
TBS Climate Transition Plan
Charting a Profitable Path to a Sustainable Future
Our Climate Transition Plan (CTP) defines how TBS will achieve carbon neutrality while strengthening the resilience and profitability of our business.
The plan outlines how we are divesting high-emission assets, reallocating capital toward low-carbon sectors, and embedding climate considerations into investment decisions, risk management, and operations.
This disciplined approach enables TBS to reduce emissions while building scalable growth platforms in environmental services, clean energy, and sustainable mobility.
Key Highlights:
- ~86% reduction in operational emissions following the divestment of two coal-fired power plants.
- Carbon neutrality target by 2030.
- US$600 million investment plan to accelerate low-carbon businesses.
- US$283 million already deployed as of Q1 2025.
- Waste management now contributing 39% of consolidated revenue and 88% of adjusted EBITDA.
