Belém, Brazil. At the world’s largest climate forum, PT Vale Indonesia -- part of the MIND ID mining holding -- reinforced its strong commitment to supporting Indonesia’s transition toward a low-carbon future.

Speaking at COP30 in Belém, Brazil, PT Vale stressed that Indonesia is not only a leading global nickel supplier but is increasingly positioned as a pioneer in sustainable critical-mineral development.

During the “Emerging Technologies to Respond to Climate Change” talk show at the Indonesia Pavilion on Friday, PT Vale outlined how responsible mining practices, next-generation technology, and strategic downstream partnerships -- particularly with Huayou Indonesia -- are shaping a new era for the electric-vehicle battery ecosystem.

The session brought together key stakeholders from across Indonesia’s nickel value chain. The discussion was opened by the Environment Ministry through a video address from Hanifah Dwi Nirwana, Acting Deputy for Hazardous Waste and Materials Management, who highlighted the government’s commitment to environmental governance as an anchor for industrial transformation.

This was followed by remarks from Amsor, Director of Waste Management at the Ministry, who underscored the need for regulatory integrity, strengthened transparency, and alignment with international sustainability standards in advancing Indonesia’s green-industry agenda.

Vale’s Decarbonization Targets and Technology Transformation
From an industry perspective, Budiawansyah, Director and Chief Sustainability & Corporate Affairs Officer of PT Vale, presented the company’s climate ambition.

He noted that Vale’s Sorowako operations are undergoing major technological transformation to achieve an absolute emissions reduction of 33 percent by 2030, alongside a 50 percent reduction in nickel product carbon intensity. These targets are being driven by innovations such as heat-recovery systems, ore-dewatering optimization, and electrification of processing infrastructure.

According to Budiawansyah, these initiatives not only reduce emissions but also improve efficiency, generating substantial annual energy savings and CO₂ reductions.

“Our message at COP30 is clear: responsible, climate-aligned growth is a pillar of our strategy,” he said. “Through innovation and collaboration -- including our strategic downstream partnership with Huayou -- we are committed to delivering low-carbon nickel that meets the expectations of global stakeholders.”

Huayou: Driving Low-Carbon Battery Materials Through Advanced Hydrometallurgy
Echoing the commitment, Stevanus, Director of Public Affairs at Huayou Indonesia, explained how Huayou’s technological innovations deliver meaningful climate impact.

“We are implementing new technological breakthroughs in advanced hydrometallurgy -- from waste-heat recovery that can supply more than 70 percent of project electricity needs, to self-flow ore slurry, CO₂ solidification, electrification, and waste reuse,” he said. “Together, these enable us to reduce over 2 tCO₂e per ton of nickel.”

Stevanus added that the Vale–Huayou partnership represents a shared mission to accelerate cleaner and more efficient battery-material processing.

“By combining Huayou’s hydrometallurgical innovations with Vale’s ESG foundation, we are helping position Indonesia as the global benchmark for low-carbon battery materials,” he said.

The panel also featured Aladin Sianipar, Vice President HSE at Harita Nickel, who highlighted the importance of circularity and waste reuse in industrial decarbonization.

Collectively, the speakers conveyed a strong message: Indonesia’s nickel industry is undergoing one of the most significant transformations in its history -- powered by collaboration between policymakers, upstream miners, midstream processors, and downstream technology innovators.

ESG Progress and Global Trust
During COP30, PT Vale also highlighted its latest Sustainalytics ESG Risk Rating of 23.7 -- the best score in the company’s history -- positioning it among the top performers in the global diversified metals and mining category.

The achievement reinforces PT Vale’s credibility as a responsible nickel producer in a sector under increasing environmental scrutiny. According to the company, global trust can only be built through consistency -- transparent reporting, strong governance, disciplined operations, and long-term investments aligned with climate expectations.

A Clear Signal From Indonesia to the Global Climate Community
The panel concluded with an optimistic outlook: Indonesia’s success in the global EV supply chain will not be defined solely by resource reserves or production volume, but by the values embedded into industrial development -- sustainability, transparency, advanced technology, and strong collaboration.

From Belém -- thousands of kilometers from Sorowako, Bahodopi, Pomalaa, and Morowali, the heart of Indonesia’s nickel leadership -- PT Vale delivered a clear message: Indonesia’s critical minerals are shaping the future of global decarbonization, and the country is determined to lead with ambition and accountability.

Through strategic partnerships, clean-energy-based processing pathways, and a firm commitment to ESG excellence, PT Vale is contributing to the transformation of the nickel ecosystem -- where innovation accelerates climate progress and Indonesia emerges as a responsible strategic force in the world’s clean-energy transition.

The Vale–Huayou partnership now stands as a model for how industry players can collaborate to deliver climate impact while reinforcing Indonesia’s global leadership at a time when responsible critical-mineral supply has never been more important.
