Our commitment in biodiversity
Protecting biodiversity is closely related to sustainability commitments. We have also included initiatives related to biodiversity in PT Vale's Environment, Health, Safety and Sustainability (EHSS) Policy, as well as specific policies on every environmental aspect. The initiatives we carry out are also in line with the material topics of reporting and the Principles of Sustainable Mining Management Based on the Sustainable Development Framework from the International Council on Mining and Metals (ICMM), which are aligned with the Five Environmental Management Commitments for 2022.
The five environmental commitments that become our focus, namely,
Low carbon agenda,
Reducing the burden of landfills
Reducing the intensity of water consumption,
Reclamation of post-mining land and land rehabilitation outside the Contract of Work, as well as
Biodiversity conservation.
Landfill or final disposal site (TPA) load reduction
In 2022, we continued our policy of reducing the burden of landfills with reference to the PROPER policy.
Waste management iscarried out through efforts to reduce, reuse, recycle, and recover (4R).
No hazardous waste is shipped internationally and there are no spills of environmentally hazardous waste materials.

Reducing the Intensity of Water Consumption
We strive to optimize water use for every ton of nickel in matte produced, in accordance with PT Vale's Water Efficiency and Wastewater Pollution Load Reduction Policy. The policy in question can be seen at: https://www.vale.com/in/kebijakan-kami
The largest water demand is fulfilled by hydropower operations on the Larona River, with water sources from Lake Matano, Mahalona and Towuti. Water from the lake flows into the reservoir in the dam and is forwarded to the canal to drive turbines. The amount of water consumed is the same as the water taken from the lake, and no water is taken from the water stress area.
Total water consumption in 2022 reached 8,519,762 m3, equivalent to 8,519.762 megalitres. This consumption has decreased by aroound 1.86% from water consumption in 2021.
The Intensity Value of Water Consumption in 2022 is 141.77 m3/Ton Ni. This figure increased by around 6.71% from the previous year's Water Consumption Intensity.

Land Reclamation and Rehabilitation
PT Vale is carrying out progressive post-mining land reclamation and watershed rehabilitation with a target of 70% of the land being reclaimed and rehabilitated by 2025.
Until the end of 2022, the total area of land being rehabilitated is 10,280 hectares, 10,000 hectares of which are outside the operational area. Meanwhile, a total of 3.7 million trees have been planted, including 17,631 endemic trees.
Realization of environmental management costs in 2022 was recorded at US$20,142,498 for the Sorowako and Pomalaa areas.
Apart from rehabilitating 10,000 hectares of watersheds (DAS) outside the concession area, the Ministry of Environment and Forestry has also entrusted us with rehabilitating 435 hectares of watersheds in six sub-districts in West Java Province. Until 2022, we have returned 140 hectares of critical watershed land that has been rehabilitated to the Ministry of Environment and Forestry.
Land Management and Biodiversity Performance
PT Vale carries out open pit mining activities, which has an impact on changes in the natural setting, ecosystems and biodiversity in it. To minimize the impact, every year we enforce an open area restrictions policy for mining activities, with reference to reclamation guarantee documents that have been approved by the Ministry of Energy and Mineral Resources.
In 2022 the remaining open land area is limited to a maximum of 1,981.57 hectares, while the actual area has reached 199.80 hectares. The cumulative area of land for mining operations until the end of 2022 is 5,458.60 ha.
In accordance with the principles in the ICMM Sustainable Development Framework, PT Vale does not carry out mining activities in world heritage sites.
