As the world’s 60% producer of nickel, Indonesia is strategically positioned to become a green powerhouse – a supplier of green minerals needed in the global energy transition. The National Nickel Industry Decarbonization Roadmap has been developed as a guide for the government, industry, and society to realize a low-carbon nickel industry, in line with the Golden Indonesia 2045 Vision outlined in the 2025–2060 National Long-Term Development Plan (RPJPN). For the industry, this document provides a trajectory that serves as a reference in setting emission reduction targets at the company level, in response to growing demand for low-carbon products from downstream industries, financial institutions, and consumers. Meanwhile, for the government, the roadmap offers policy recommendations to build an ecosystem that supports the implementation of decarbonization strategies, considering persistent challenges such as limited infrastructure, high costs, and regulatory uncertainty.
