Emission and Energy Management

PT Vale optimizes energy efficiency and addresses climate adaptation by containing conventional air pollutants (SOx, NOx, PM) across its operations. Backed by self-generated renewable hydropower, the company scales green energy transitions to lower absolute emissions and drive systemic improvements in its global energy efficiency indicators.

Approach

Energy and emissions management is a key component of PT Vale Indonesia's environmental stewardship across our mining operations and growth projects. We are committed to improving energy efficiency, reducing greenhouse gas (GHG) emissions, and managing air emissions through integrated operational practices, responsible resource use, and compliance with applicable environmental regulations.

As PT Vale Indonesia expands its operations in Sorowako, Pomalaa, Morowali, and the Sorowako Limonite Project, we continue to incorporate energy efficiency and lower-carbon principles into project development and operational planning. These efforts support the Company's long-term transition toward more sustainable and resilient mining operations.

For our Sorowako operation, where nickel mining and processing are fully integrated and powered predominantly by self-generated renewable hydropower, we have established a Decarbonization Roadmap that identifies initiatives such as electrification, process optimization, waste heat recovery, and diesel reduction. This roadmap supports Sorowako's target to reduce absolute Scope 1 and Scope 2 GHG emissions by 33% by 2030 from a 2017 baseline, while maintaining safe, reliable, and efficient operations.
