In recent years, ANTAM has been focusing on decarbonisation and renewable energy. The company has set a target to reduce its carbon emissions by 30% by 2030. To achieve this, ANTAM has implemented several initiatives such as the use of renewable energy sources and the adoption of energy-efficient technologies.

One of ANTAM's key initiatives in decarbonisation is the use of renewable energy sources. The company has installed a 1 MW solar power plant at its ferronickel plant in Pomalaa, Southeast Sulawesi. The solar power plant generates electricity that is used to power the plant's operations, reducing the company's reliance on fossil fuels. ANTAM is also exploring the use of other renewable energy sources such as wind and hydro power.

ANTAM has also implemented a corporate power purchase agreement (PPA) for renewable energy. The company has signed a PPA with state-owned electricity company PLN to purchase electricity generated from a 50 MW wind power plant in South Sulawesi. The PPA will enable ANTAM to reduce its carbon emissions and support the development of renewable energy in Indonesia.

In addition to renewable energy, ANTAM has also implemented energy-efficient technologies in its operations. The company has installed energy-efficient lighting and air conditioning systems at its offices and plants. ANTAM has also implemented a waste heat recovery system at its ferronickel plant in Pomalaa, which captures waste heat from the plant's operations and converts it into electricity.

The company has been included in the Dow Jones Sustainability Index (DJSI) for three consecutive years, which recognizes companies that demonstrate leadership in sustainability. ANTAM has also received the Green Industry Award from the Indonesian Ministry of Industry for its efforts in environmental management.
