How can mining companies achieve net-zero emissions by 2050?

The global economy is heavily influenced by the mining industry, which is a major source of greenhouse gases. Faced with the challenges of combating climate change and pressure from environmental protection bodies, many mining companies around the world have committed to achieving zero net emissions by 2050. It’s an ambitious goal that will require a thorough overhaul of processes, the adoption of innovative technologies and a review of business models.

Transitioning to renewable energy

One of the most significant steps mining companies can take is transitioning their energy sources from fossil fuels to renewables such as solar, wind, and hydropower. Renewable energy can power mining operations, including processing plants and auxiliary equipment. For instance, Rio Tinto has committed to using 100% renewable electricity at several of its sites, significantly reducing operational emissions (Rio Tinto, 2023). This transition not only lowers emissions but can also reduce long-term energy costs.

Electrifying mining equipment

Diesel-powered vehicles and machinery are among the largest sources of direct emissions in mining. Electrification of equipment—such as haul trucks, excavators, and drills—is a key strategy. Companies like BHP and Fortescue Metals Group have already begun deploying electric and hydrogen-fueled vehicles at their operations (BHP, 2024). These advancements reduce carbon emissions and improve air quality, creating a safer working environment for miners.

Enhancing energy efficiency

Energy efficiency measures are a cost-effective way to lower emissions. These measures include optimizing grinding and crushing processes, retrofitting equipment with energy-efficient components, and implementing advanced monitoring systems. For example, Anglo American has adopted real-time data analytics to optimize energy use across its operations, achieving a 15% reduction in energy consumption over the past decade (Anglo American, 2022).

Implementing carbon capture, utilization, and storage (CCUS)

Carbon Capture, Utilization, and Storage (CCUS) technology offers a solution for capturing CO₂ emissions from mining operations and safely storing or repurposing them. While the technology is still evolving, some companies are piloting CCUS projects. For instance, Vale is exploring CCUS in Brazil to mitigate emissions from its iron ore processing facilities (Vale, 2023). This approach can complement other decarbonization efforts, particularly for operations where emissions are challenging to eliminate.

Circular economy practices

Mining companies can reduce emissions by adopting circular economy principles, such as recycling and reusing materials. By processing waste and scrap materials, companies can minimize the need for virgin resource extraction. For instance, Glencore has implemented a recycling program for electronic waste, recovering valuable metals and reducing the carbon footprint associated with mining new resources (Glencore, 2024).

Collaboration and partnerships

Achieving net-zero emissions requires collaboration across the industry and beyond. Partnerships with technology providers, governments, and research institutions can accelerate the development and deployment of innovative solutions. The International Council on Mining and Metals (ICMM) has established frameworks for collaborative action, enabling member companies to share best practices and resources (ICMM, 2023).

Setting clear targets and transparent reporting

Establishing interim targets and transparent reporting mechanisms is essential for tracking progress toward net-zero emissions. Many companies have committed to science-based targets aligned with the Paris Agreement. Transparent reporting ensures accountability and builds trust among stakeholders. For example, Newmont Corporation publishes annual sustainability reports detailing its emissions reduction achievements and challenges (Newmont, 2023).

Conclusion

Achieving net-zero emissions by 2050 is a complex but attainable goal for the mining sector. By transitioning to renewable energy, electrifying equipment, enhancing energy efficiency, adopting CCUS, embracing circular economy practices, fostering collaboration, and ensuring transparency, mining companies can significantly reduce their carbon footprint. These efforts not only align with global climate goals but also position companies as leaders in sustainable development, securing their license to operate in a low-carbon future.
