Unlocking Value in Mining: Where ESG Meets Efficiency

Mining companies prioritize managing inflation, accessing cheaper capital, and meeting global ESG goals. In this context, operators must carefully assess suppliers and service providers, considering ESG performance, technological capabilities, and long-term benefits.

Experts gathered at the second edition of the Mexico Mining Forum PDAC 2025 agreed that one of the most pressing challenges in the sector is reducing its carbon footprint. According to CAMIMEX’s Sustainability Report 2024, the mining sector’s energy mix comprises 65% fossil fuels and 35% renewables. In 2023, 40 mining operations produced and consumed clean energy. The chamber points out that adopting electric technology offers greater efficiency in lighting and vehicle engines, helping to reduce operating costs, as energy represents over 30% of mining operating costs. 

Mariano Souto, Director General, Aggreko, noted that efficiency can be improved by using emerging technology like AI regardless of the energy mix a project uses. As for solar energy, he notes that including AI can help improve efficiency by optimizing energy production, managing storage, and ensuring better distribution, ultimately reducing costs and enhancing performance. 

Mining companies are increasingly considering transitioning to electric vehicles (EVs) to improve efficiency and reduce environmental impact. This shift offers potential benefits, including improved health and safety conditions for workers through zero diesel emissions, reduced heat, and lower noise and vibration levels. AI can also help improve these processes to boost greater efficiencies. “With the power of AI, we can simulate and find the most efficient routes, reducing the cost per tonne. The development of new technologies is crucial and cannot be overlooked; it is now an integral part of the development of our vehicles,” stressed Said Vivas, Mining Director, Scania.

Alejandro Hernández, Director General, ACD Group, highlighted the potential to increase efficiency through data correlation driven by sensors, AI, and the Internet of Things (IoT). "If mining units had a dedicated department to collect and analyze data, it could improve resource management and add value,” he added. Additionally, incorporating sensors and AI enables more accurate tracking of equipment wear and better scheduling of maintenance. This approach can improve environmental performance, reduce costs associated with unexpected equipment failures, and enhance overall operational efficiency by minimizing downtime and optimizing resource use.

EVs can also lower operating costs by reducing the need for ventilation and cooling, while, as technology becomes more efficient, faster acceleration and loading times can enhance productivity. According to industry estimates, advancements in EV technology have brought the total cost of ownership to approximately 17% below that of internal combustion engines (ICE). 

Despite the advantages of EVs, Vivas emphasized the need to address technology and infrastructure gaps, both at mine sites and in the surrounding country. "It is not just the mining operations, there are also long-distance vehicles transporting supplies to the site. The main challenge is that the area has not yet invested in charging stations," he added.

Some mining companies are exploring alternative fuels like green hydrogen, which is considered ideal for reducing emissions. Experts in the energy sector view liquefied natural gas as a transition fuel because it provides reliable, affordable energy while producing 50% fewer emissions than oil or diesel. Rodolfo Garza Alanis, Business Development and Engineering Manager, SOLENSA, notes that besides improving environmental and cost performance, the use of this transition fuel also contributes to community engagement as community members are included when implementing it. 

Experts point out that repairing operating equipment is an effective strategy for reducing environmental impact, particularly in addressing Scope 3 CO2 emissions. Estimates suggest that asset repairs can lower these indirect emissions by up to 90%, reducing electronic waste, supporting more efficient resource use, and contributing to the circular economy. In this context, having a reliable partner to supply spare parts is important for maintaining operational continuity and managing environmental responsibilities. Consistent access to quality spare parts allows companies to extend equipment lifespan, reducing the demand for new manufacturing and minimizing waste.
