Rio Tinto has taken a decisive step toward reshaping the future of copper supply. The mining major announced a strategic collaboration with Amazon Web Services (AWS) that connects breakthrough mining technology with surging demand from data centers and artificial intelligence. Under the agreement, AWS became the first customer of Nuton® Technology following its successful industrial-scale deployment at the Johnson Camp copper mine in the United States.
The deal links cleaner copper production with the digital infrastructure powering the global AI economy.
How AWS Cloud Technology Is Powering Nuton’s Bioleaching Breakthrough
Nuton, a Rio Tinto venture, focuses on nature-based bioleaching technologies designed to extract copper from low-grade and previously uneconomic ores. Last month, the company achieved a major milestone by deploying its proprietary system at an industrial scale at Gunnison Copper’s Johnson Camp mine in Arizona.

The press release highlights that under the two-year agreement, AWS will use the first Nuton-produced copper in components across its U.S. data centers. Copper is essential to these facilities, playing a critical role in electrical cables, busbars, transformers, motors, printed circuit boards, and processor heat sinks.
At the same time, AWS will also provide cloud-based data and analytics to support Nuton’s operations. This digital support will speed up process optimization and improve copper recovery.
AWS platforms will simulate heap-leach performance and feed advanced analytics into Nuton’s decision systems. As a result, the company can fine-tune acid and water use. It can also better predict copper recovery.
“This collaboration with Nuton Technology represents exactly the kind of breakthrough we need—a fundamentally different approach to copper production that helps reduce carbon emissions and water use. As we continue to invest in next-generation carbon-free energy technology and expand our data centre operations, securing access to lower-carbon materials produced close to home strengthens both our supply chain resilience and our ability to decarbonize at scale.”
Microbe-Driven Copper, Digitally Scaled
Nuton’s modular bioleaching system uses naturally occurring microorganisms to extract copper from primary sulphide ores. Unlike traditional mining methods, the process avoids energy-intensive crushing, concentrating, and smelting.
When combined with digital tools, the technology can scale faster and adapt to different ore bodies. Overall, this approach shortens the path from pilot testing to full production. At the same time, it lowers environmental impact.
Shorter Supply Chains and Cleaner Copper
Additionally, Nuton’s process produces 99.99% pure copper cathode directly at the mine gate. This eliminates the need for concentrators, smelters, and refineries, significantly shortening the mine-to-market supply chain.
Compared with traditional processing routes, Nuton is expected to use substantially less water and generate lower carbon emissions. The system also recovers copper from material previously classified as waste, improving overall resource efficiency.
At Johnson Camp, these benefits are already material. The mine is now the lowest-carbon primary copper producer in the United States on a mine-to-refined-metal basis commonly used by the industry.

Verified Low Carbon and Water Footprints
A third-party life cycle assessment confirmed that Nuton copper from Johnson Camp is expected to have a full-scope carbon footprint of 2.82 kg CO₂e per kilogram of copper, covering Scope 1, 2, and 3 emissions. By comparison, global primary copper production typically ranges from about 1.5 to 8.0 kg CO₂e per kilogram, depending on technology and location.
Nuton has also matched 100% of the site’s electricity consumption by purchasing 134,000 Green-e Energy certified renewable energy certificates. Water intensity is expected to be 71 liters per kilogram of copper, well below the global industry average of roughly 130 liters.
Skarn Associates independently validated both the carbon and water intensity data. Additional environmental benefits include lower energy use, on-site clean energy generation, and zero tailings, removing the risk of tailings dam failures.
A Strategic Copper Asset for the United States
Johnson Camp is one of the largest open-pit copper projects in the U.S., with measured and indicated resources of 551 million tons at an average grade of 0.35% copper. At scale, it could supply around 8% of recent annual U.S. domestic copper production.
The project is targeting production of approximately 30,000 tonnes of refined copper over a four-year deployment period. This comes as the U.S. has formally designated copper as a critical mineral due to its importance for energy systems, digital infrastructure, and national security.

IEA and S&P Global Warn of Surging Demand and Supply Risks
The International Energy Agency (IEA) has highlighted that the rapid growth of artificial intelligence is driving a sharp expansion of data centers worldwide. While estimates vary widely, the IEA notes that copper use in data centers could reach 250,000 to 550,000 tonnes by 2030, accounting for up to 12% of global copper demand, depending on how quickly AI adoption accelerates.

At the same time, a fresh analysis from S&P Global has warned that growth in artificial intelligence, electrification, and defense could push global copper demand up by 50% by 2040. However, without major investment in new mining projects and recycling, supply is expected to fall short.

Yet, as existing copper resources age and ore grades decline, the market could face a 10 million metric ton annual supply shortfall by 2040.

Why the Rio Tinto–AWS Deal Matters
Against this backdrop, the collaboration between Rio Tinto and AWS carries strategic weight. It connects low-carbon copper supply directly with one of the world’s fastest-growing sources of demand. It also shows how digital infrastructure and nature-based mining solutions can work together to reduce emissions while expanding supply.
As AI, electrification, and energy transition pressures continue to build, innovations like Nuton’s bioleaching technology could play a critical role in closing the global copper gap—cleanly, efficiently, and at scale.
To summarize the importance of this deal, Rio Tinto Copper Chief Executive Katie Jackson said,
“This collaboration is a powerful example of how industrial innovation and cloud technology can combine to deliver cleaner, lower-carbon materials at scale. Nuton has already proven its ability to rapidly move from idea to industrial production, and AWS’s data and analytics expertise will help us to accelerate optimisation and verification across operations.
She further added:
“Importantly, by bringing Nuton copper into AWS’s U.S. data-centre supply chain, we’re helping to strengthen domestic resilience and secure the critical materials those facilities need, closer to where they’re used. Together we can supply the copper critical to modern data infrastructure while demonstrating how mining can contribute to more sustainable supply chains.”

Carbon Footprint
The real cost of 1 tonne of CO2: Translating carbon into hectares
Every business carbon footprint report ends with a number, the amount of carbon emissions produced by the business, less the amount of carbon reduced and offset, given in tonnes of CO₂. Many of the people who sign off on that number, including those who paid for it, cannot picture what it represents on the ground. A tonne is a unit of mass. CO₂ is invisible. The link between the amount offset in the report and a real piece of restored forest somewhere in the world is almost never indicated.

How Climate Change Is Raising the Cost of Living
Americans are paying more for insurance, electricity, taxes, and home repairs every year. What many people may not realize is that climate change is already one of the drivers behind those rising costs.
For many households, climate change is no longer just an environmental issue. It is becoming a cost-of-living issue. While climate impacts like melting glaciers and shrinking polar ice can feel distant from everyday life, the financial effects are already showing up in monthly budgets across the country.
Today, a larger share of household income is consumed by fixed costs such as housing, insurance, utilities, and healthcare. (3) Climate change and climate inaction are adding pressure to many of those expenses through higher disaster recovery costs, rising energy demand, infrastructure repairs, and increased insurance risk.
The goal of this article is to help connect climate change to the everyday financial realities people already experience. Regardless of where someone stands on climate policy, it is important to recognize that climate change is already increasing costs for households, businesses, and taxpayers across the United States.
More conservative estimates indicate that the average household has experienced an increase of about $400 per year from observed climate change, while less conservative estimates suggest an increase of $900.(1) Those in more disaster-prone regions of the country face disproportionate costs, with some households experiencing climate-related costs averaging $1,300 per year.(1) Another study found that climate adaptation costs driven by climate change have already consumed over 3% of personal income in the U.S. since 2015.(9) By the end of the century, housing units could spend an additional $5,600 on adaptation costs.(1)
Whether we realize it or not, Americans are already paying for climate change through higher insurance premiums, energy costs, taxes, and infrastructure repairs. These growing expenses are often referred to as climate adaptation costs.
Without meaningful climate action, these costs are expected to continue rising. Choosing not to invest in climate action is also choosing to spend more on climate adaptation.
Here are a few ways climate change is already increasing the cost of living:
- Higher insurance costs from more frequent and severe storms
- Higher energy use during longer and hotter summers
- Higher electricity rates tied to storm recovery and grid upgrades
- Higher government spending and taxpayer-funded disaster recovery costs
The real debate is not whether climate change costs money. Americans are already paying for it. The question is where we want those costs to go. Should we invest more in climate action to help reduce future climate adaptation costs, or continue paying growing recovery and adaptation expenses in everyday life?
How Climate Change Is Increasing Insurance Costs
There is one industry that closely tracks the financial impact of natural disasters: insurance. Insurance companies are focused on assessing risk, estimating damages, and collecting enough revenue to cover losses and remain financially stable.
Comparing the 20-year periods 1980–1999 and 2000–2019, climate-related disasters increased 83% globally from 3,656 events to 6,681 events. The average time between billion-dollar disasters dropped from 82 days during the 1980s to 16 days during the last 10 years, and in 2025 the average time between disasters fell to just 10 days. (6)
According to the reinsurance firm Munich Re, total economic losses from natural disasters in 2024 exceeded $320 billion globally, nearly 40% higher than the decade-long annual average. Average annual inflation-adjusted costs more than quadrupled from $22.6 billion per year in the 1980s to $102 billion per year in the 2010s. Costs increased further to an average of $153.2 billion annually during 2020–2024, representing another 50% increase over the 2010s. (6)
In the United States, billion-dollar weather and climate disasters have also increased significantly. The average number of billion-dollar disasters per year has grown from roughly three annually during the 1980s to 19 annually over the last decade. In 2023 and 2024, the U.S. recorded 28 and 27 billion-dollar disasters respectively, both setting new records. (6)
The growing impact of climate change is one reason insurance costs continue to rise. “There are two things that drive insurance loss costs, which is the frequency of events and how much they cost,” said Robert Passmore, assistant vice president of personal lines at the Property Casualty Insurers Association of America. “So, as these events become more frequent, that’s definitely going to have an impact.” (8)
After adjusting for inflation, insurance costs have steadily increased over time. From 2000 to 2020, insurance costs consistently grew faster than the Consumer Price Index due to rising rebuilding costs and weather-related losses.(3) Between 2020 and 2023 alone, the average home insurance premium increased from $75 to $360 due to climate change impacts, with disaster-prone regions experiencing especially steep increases.(1) Since 2015, homeowners in some regions affected by more extreme weather have seen home insurance costs increased by nearly 57%.(1) Some insurers have also limited or stopped offering coverage in high-risk areas.(7)
For many families, rising insurance costs are no longer occasional financial burdens. They are becoming recurring monthly expenses tied directly to growing climate risk.
How Rising Temperatures Increase Household Energy Costs

The financial impacts of climate change extend beyond insurance. Rising temperatures are also changing how much energy Americans use and how utilities plan for future electricity demand.
Between 1950 and 2010, per capita electricity use increased 10-fold, though usage has flattened or slightly declined since 2012 due to more efficient appliances and LED lighting. (3) A significant share of increased energy demand comes from cooling needs associated with higher temperatures.
Over the last 20 years, the United States has experienced increasing Cooling Degree Days (CDD) and decreasing Heating Degree Days (HDD). Nearly all counties have become warmer over the past three decades, with some areas experiencing several hundred additional cooling degree days, equivalent to roughly one additional degree of warmth on most days. (1) This trend reflects a warming climate where air conditioning demand is increasing while heating demand generally declines. (4)
As temperatures continue rising, households are expected to spend more on cooling than they save on heating. The U.S. Energy Information Administration (EIA) projects that by 2050, national Heating Degree Days will be 11% lower while Cooling Degree Days will be 28% higher than 2021 levels. Cooling demand is projected to rise 2.5 times faster than heating demand declines. (5)
These projections come from energy and infrastructure experts planning for future electricity demand and grid capacity needs. Utilities and grid operators are already preparing for higher peak summer electricity loads caused by rising temperatures. (5)
Longer and hotter summers also affect how homes and buildings are designed. Buildings constructed for past climate conditions may require upgrades such as larger air conditioning systems, stronger insulation, and improved ventilation to remain comfortable and energy efficient in the future. (10)
For many households, this means higher monthly utility bills and potentially higher long-term home improvement costs as temperatures continue to rise.
How Climate Change Affects Electricity Rates
On an inflation-adjusted basis, average U.S. residential electricity rates are slightly lower today than they were 50 years ago. (2) However, climate-related damage to utility infrastructure is creating new upward pressure on electricity costs.
Electric utilities rely heavily on above-ground poles, wires, transformers, and substations that can be damaged by hurricanes, storms, floods, and wildfires. Repairing and upgrading this infrastructure often requires substantial investment.
As a result, utilities are increasing electricity rates in response to wildfire and hurricane events to fund infrastructure repairs and future mitigation efforts. (1) The average cumulative increase in per-household electricity expenditures due to climate-related price changes is approximately $30. (1)
While this increase may appear modest today, utility costs are expected to rise further as climate-related infrastructure damage becomes more frequent and severe.
How Climate Disasters Increase Government Spending and Taxes
Extreme weather events also damage public infrastructure, including roads, schools, bridges, airports, water systems, and emergency services infrastructure. Recovery and rebuilding costs are often funded through taxpayer dollars at the federal, state, and local levels.
The average annual government cost tied to climate-related disaster recovery is estimated at nearly $142 per household. (1) States that frequently experience hurricanes, wildfires, tornadoes, or flooding can face even higher public recovery costs.
These expenses affect taxpayers whether they personally experience a disaster or not. Climate-related recovery spending can increase pressure on public budgets, emergency management systems, and infrastructure funding nationwide.
Reducing Climate Costs Through Climate Action
While this article focuses on the growing financial costs associated with climate change, the issue is not only about money for many people. It is also about recognizing our environmental impact and taking responsibility for reducing it in order to help preserve a healthy planet for future generations.
While individuals alone cannot solve climate change, collective action can help reduce future climate adaptation costs over time.
For those interested in taking action, there are three important steps:
- Estimate your carbon footprint to better understand the emissions connected to your lifestyle and activities.
- Create a plan to gradually reduce emissions through energy efficiency, cleaner technologies, and more sustainable choices.
- Address remaining emissions by supporting verified carbon reduction projects through carbon credits.
Carbon credits are one of the most cost-effective tools available for climate action because they help fund projects that generate verified emission reductions at scale. Supporting global emission reduction efforts can help reduce the long-term impacts and costs associated with climate change.
