Caterpillar and Vale sign new agreement that includes carbon-reduction initiatives
The companies will collaborate on the development and testing of dual-fuel and battery-electric mining haul trucks

Vale and Caterpillar have signed a five-year global framework agreement meant to strengthen collaboration between the two companies. The objectives are to increase focus on productivity and innovation, including carbon reduction initiatives.
The companies also reaffirmed their commitment made in April 2024 to cooperate towards the development of a dual-fuel haul truck powered by diesel and ethanol. Vale also intends to test a battery electric haul truck and the Cat Dynamic Energy Transfer System (DET) under development by Caterpillar.
"The framework agreement represents an evolution in our relationship with Caterpillar, amplifying our focus on maximizing the performance of Vale's assets and allowing us to advance on our decarbonization path in an economically responsible way," says Marco Braga, Vale's procurement director.
"The agreement with Vale reflects our commitment to developing solutions that support our customers' operational and sustainability goals," says Denise Johnson, group president of Caterpillar's Resource Industries segment.
Sustainability in the spotlight, integrated with advances in innovation and technology
On average, diesel fuel use in Vale's operations is responsible for 15 percent of the company's direct CO₂eq emissions. The adoption of more sustainable technologies is part of a strategic plan to mitigate environmental impacts while maintaining competitiveness.
The dual-fuel haul truck to be powered by ethanol and diesel that is under development by Caterpillar would initially equip trucks capable of carrying 240 tons of ore. In the future, the technology may be extended to trucks with a capacity of 320 tons. In total, there are more than 150 of both models in operation at Vale. Initial testing is to be completed at Caterpillar's facilities in the U.S. followed by additional validation and testing of dual-fuel trucks at Vale's operations.
"Decarbonization is a major challenge today, which will only be overcome by investing in solutions such as alternative fuels and electrification to reduce emissions without compromising efficiency and safety," explains João Turchetti, Vale's Decarbonization Engineering director.
"As global industry leaders, Vale and Caterpillar are seeking not only to meet the demands of the mining sector but also to anticipate technological and environmental trends," says Marc Cameron, senior vice president of Resource Industries Sales, Services and Technology at Caterpillar.
