Indonesia's mining sector contributes approximately 7.8% of national GDP and is the world's leading producer of nickel, tin, and thermal coal. The sector generates over USD 50 billion in export revenue annually and is central to Indonesia's industrialization strategy. However, it also carries one of the highest environmental footprints of any industry including habitat destruction, acid mine drainage, heavy metal contamination, and significant GHG emissions estimated at over 200 million tonnes CO₂ equivalent per year from coal mining alone.

The global shift toward critical minerals for the energy transition nickel for EV batteries, copper for renewables is raising the stakes for environmental accountability. The EU's Carbon Border Adjustment Mechanism (CBAM), expected to cover metals by 2026, will penalize carbon-intensive production. Meanwhile, international investors, OECD due diligence standards, and the Indonesian government's PROPER system are imposing stricter environmental performance benchmarks. Mining companies that fail to demonstrate credible sustainability programs risk losing financing, market access, and their operating licenses.
