Advancing decarbonisation and climate change action

10 Sep 2025

PT Indo Tambangraya Megah Tbk (‘ITM’) is an Indonesian energy company, active in the coal mining and renewables industries. Looking to advance its decarbonisation efforts and further develop its climate change strategy, the company enlisted the support of Intertek Assuris.

Our team started by verifying the accuracy of ITM’s 2023 base year emissions through limited assurance, validating the methodologies and assumptions underpinning its 2030 emissions projections, and analysing potential reduction opportunities to support the achievement of its 2030 reduction target.

We then presented ITM’s Board of Directors with a range of potential emission reduction scenarios aimed at achieving the company’s 2030 reduction target. By comparing the verified base year emissions with the validated 2030 projections, we quantified the required emissions reduction and identified key emission hotspots to help prioritise areas for action and investment.

Reduction plans were reviewed alongside peer benchmarks, with input from greenhouse gas and mining experts, resulting in a shortlist of viable reduction opportunities. For each opportunity, we conducted detailed case studies, assessing advantages and disadvantages, implementation considerations, indicative costs and payback periods, relevant industry examples, and the role of carbon offsets.

The engagement concluded with Intertek submitting a strategic path forward, providing ITM and its subsidiaries with a robust foundation for achieving their climate goals through more informed decision-making around investment and implementation strategies.
