Mining of nickel in Indonesia escalates, posing threats to the environment in support of the electric vehicle industry expansion.
Indonesia, the world's leading producer of nickel, is experiencing a significant expansion in its nickel sector in response to the global surge in demand for electric vehicle (EV) batteries. This transformation, driven by a combination of factors, has made Indonesia a critical hub in the EV battery supply chain.
Residents of Kawasi village in Indonesia have reported a rise in respiratory infections and concerns over drinking water quality, as well as damage to marine ecosystems, due to nickel mining. These environmental concerns have been echoed by environmental activists, who express worries about the impact of mining on Indonesia's biodiversity.
According to Nusantara Atlas, approximately 193,830 hectares of forest were lost between 2000 and 2023 due to nickel mining. This deforestation has led to an estimated 2 million metric tonnes of carbon dioxide equivalent in emissions in central and eastern Halmahera Island, according to Climate Rights International. The destruction of tropical forests also has significant environmental impacts, including air and water pollution.
The Indonesian government's policies have played a significant role in this boom. Since 2020, a full ban on raw nickel exports has been in place, requiring domestic purification and processing to add value within the country. This has led to the development of a complex nickel extraction and refining industry, including large industrial parks with dedicated power stations to support smelting and battery-grade nickel production.
The Indonesian government actively supports the nickel sector through deregulation, tax incentives, subsidies, and political backing, encouraging investment from domestic and foreign players, notably Chinese companies involved in mining and battery production. Major EV battery producers like China’s CATL, GEM, and South Korea’s LG Chem have established partnerships and facilities in Indonesia to secure nickel supply chains, further driving demand.
Tens of billions of dollars, much from China, have been invested in nickel mining and downstream processing, including a $6 billion EV battery megaproject that integrates nickel mining through to cathode production, enhancing Indonesia's role in the EV supply chain. The use of nickel in EV batteries has risen from 2% in 2017 to 10% in 2022, with the global demand for EV batteries increasing by 25% between 2023 and 2024.
However, the government's policy of shortening nickel mining quotas from three years to one year creates some uncertainty for mining investors. This move illustrates the government's intention to tightly manage nickel production and align it with global demand.
The European Union and the United States are also taking steps to secure critical mineral supplies, recognising the strategic importance of Indonesia's nickel reserves, which are primarily located on Sulawesi Island, with an estimated 2.6 billion tonnes of ore.
As the demand for EV batteries continues to rise sharply, it remains crucial to balance the economic benefits of nickel mining with the protection of Indonesia's environment and biodiversity.
- The rise in respiratory infections and concerns over drinking water quality in Kawasi village, Indonesia are attributed to nickel mining, a concern also shared by environmental activists regarding the impact on Indonesia's biodiversity.
