Talk of an AI boom is everywhere — not because AI itself is new. Businesses have been using chatbots and general-purpose assistants for well over a decade. Rather, the recent mainstreaming of generative AI (GenAI) is ramping up the sophistication of AI applications.

 

It’s not just talk, either. Business expenditure on AI tools clearly reflects a dramatic rise in adoption. In 2021, before the launch of OpenAI’s ChatGPT, annual corporate spending on AI software hovered around US $33 billion a year. In 2025, that number grew to about $300 billion.

Although that type of spending speaks to the value of GenAI to business, the serious expenditure is unfolding on the hardware and infrastructure side. This year, total investment in data center hardware, servers, and storage is expected to reach $1.37 trillion. These “nuts and bolts” of the AI ecosystem are vital to propping up the GenAI tools increasingly being deployed in companies around the world. (For more on the AI-driven surge in data center and compute infrastructure, see Arthur D. Little [ADL] Viewpoint “Giga Scale: The AI Infrastructure Gold Rush.”)

But there’s a problem. Generating huge computational power to make cutting-edge AI tools work requires vast amounts of electricity (for power) and water (for cooling). Both come at high environmental costs (see PRISM article “Will an Energy Crunch Stop the AI Revolution in Its Tracks?”).

AI’s Hidden Dependencies,” a recent ADL Blue Shift report, brings these costs into sharp relief. For example, AI data centers are expected to use nearly double the amount of electricity in 2030 as they did in 2024. The trajectory for water use is similarly dramatic.

To provide a taste of what lies ahead, Albert Meige, ADL’s Director of Blue Shift, points to the evolution of ChatGPT. “If you do a query on GPT-4, it uses about the same energy as a standard Web search. Do that same query on GPT-5, and the energy use is 90 times as much.”

PRESSURE TO ACT

So, who is responsible for AI’s eco-impacts? “Not us,” conventional businesses might well say. They are just the consumers of AI tools and services, after all. Many say responsibility lies with the owners and developers of this revolutionary technology — Google, Microsoft, Amazon Web Services, Meta, and other hyperscalers.

That argument is unlikely to wash with an increasingly jittery public, warns Meige. Wait until residents close to data centers find their taps running dry, he says. Or when households in vulnerable parts of the grid see their electricity bills going up. “At some point, the physical realities of AI use are going to knock on people’s doors, and they’ll want to know what companies are doing about it,” he says.

Some regulators are putting business users front and center. Under the EU’s Corporate Sustainability Reporting Directive (CSRD), large European businesses must report on the indirect environmental impacts linked to their energy and water consumption — a list that includes their AI use.

And it’s not just external pressures making AI’s environmental record a priority for business; internal considerations are also at play. AI tools are already deeply embedded in most companies’ everyday operations. Should climate change issues somehow lead to limits on accessing these tools, the operations and profitability of these businesses could be seriously compromised.

Concerns over water availability have already led to new data centers being blocked in countries as diverse as Malaysia, Chile, and the Netherlands. Similar pressure is mounting in the US, where around two-thirds of applications for new US data centers are in water-stressed regions. Fears over grid disruptions are causing many planning authorities to rethink their strategies. (For more on the grid-side realities behind rising demand, and how stakeholders can translate constraints into investment and resilience opportunities, see ADL Viewpoint “Turning Grid Challenges into Opportunities.”)

 

DON’T WAIT

What should companies focus on? Florence Carlot, Partner in ADL’s Energy, Utilities & Resources practice, says strategic resilience should be a top priority. Companies should be increasing their flexibility and “portability” in relation to AI, she says. A good option here is designing AI architectures that segment workloads across on-premises, sovereign, and public AI platforms. Another is using architectures and formats that can migrate between clouds, vendors, or regions.

Companies should consider diversifying providers to spread their risk of operational complications should an unexpected point of failure occur. Within this wider supplier base, they might consider negotiating more flexible terms in the event of unforeseen disruptions (think export bans, resource shortages, and demand shocks). Routine stress tests in anticipation of such eventualities are high on Carlot’s should-do list.

Of course, this presupposes a business knows where it currently stands. If not, leadership is flying blind. This makes managing AI-related vulnerabilities almost impossible; the same goes for accounting for AI-linked environmental impacts. The possibility of radical innovation is also greatly reduced. Advances in clean energy and other climate-smart solutions, for example, make a net zero AI ecosystem theoretically possible. But to arrive at such a future, it’s necessary to draw a pathway to there from the present — a difficult challenge for those whose current situation remains opaque.

Interestingly, AI’s analytical power could be used to project backward, so as to redesign its own lower-carbon future, says Lukas Falcke, Assistant Professor of Digital Strategy and Innovation at VU Amsterdam, the Netherlands, and a leading advocate of digital-first solutions. Doing so, however, requires a proactive, opportunity-focused approach to auditing and reporting.

“With a digital-first mindset, it’s almost like the future becomes your starting point, because with AI you can more or less predict what emissions you will create and where, which allows you to work back from there,” Falcke says. “So instead of seeing reporting as compliance, look at it as a data-driven iteration toward a reimagined future.” (For a broader lens on using digital innovation for sustainability, see ADL’s Amplify issue “Charting a Sustainable Future with Digital-First Solutions.”)

For AI’s corporate users, gaining a clear picture of the present is harder than it sounds. As the Blue Shift report points out, obtaining meaningful data from AI operators is difficult. Fewer than 3% of new AI models disclose environmental data, down from 10% in 2023.

Not only is current data scarce, but AI providers tend to aggregate the little data they make available. This makes it tricky for companies to work out the emissions or water footprint linked to specific data centers or particular AI tools, complicating their ability to calculate the impacts of their individual AI usage.

Nevertheless, Carlot counsels against a wait-and-see approach to disclosure. Companies should also expect requirements to report on their AI-related risks and impacts to tighten in the future, she says. “Exactly when is hard to say in some jurisdictions, but there’s no doubt it will happen.”

 

At some point, the physical realities of AI use are going to knock on people’s doors, and they’ll want to know what companies are doing about it

PREPARING TO REPORT

Carlot outlines three basic measures all companies should undertake. The first and most obvious is mapping their AI touchpoints. What AI tools are they currently using? What’s the respective purpose and importance of these tools? Which vendors are they most reliant on? Do these vendors also operate data centers and, if not, who does? “Every company needs to build a basic AI inventory based on questions like these,” she says. “That creates a baseline for their material impacts along the AI value chain, which they can then use to report back.”

Steps two and three involve putting hard numbers against this inventory and stress-testing them against various scenarios. Once completed, companies should find themselves with the requisite data to set realistic targets for reducing the environmental price tag of their AI use. Carlot says that for many companies, obtaining such data requires prior steps. For example, as part of the contract-setting process with AI vendors, she suggests firms make the provision of environmental data a nonnegotiable criterion.

This demand is entirely reasonable, Carlot explains, because the expense of electricity and water means that AI firms’ usage is carefully tracked. In addition, as more companies request this data, smart AI providers will realize that eco-disclosure can be a competitive differentiator.

Companies should also consider engaging at one level up: the AI industry level. For auditing and decision-making purposes, it is important that site- and product-level information can be compared across various providers. Otherwise, companies will find themselves trying to “measure apples against oranges.”

Ideally, says Carlot, the AI industry would agree on a shared methodology for reporting planetary impacts. With reporting norms for AI firms still taking shape, proponents argue that an industry-led framework could serve as a model for legislators.

Armand Smits, Assistant Professor of Organizational Change and Design at Radboud University, the Netherlands, sees merit in such a position, but recent experience in Europe suggests trust could present a hurdle. Under the umbrella of the Climate Neutral Data Centre Pact (CNDCP), more than 100 data center operators and trade associations came together in 2021 to agree on common environmental targets and measures (see ADL Amplify article “Establishing Collective Environmental Self-Regulation in Fragmented Digital Spaces”). To date, EU legislators have not been “that supportive” of CNDCP’s proposals, Smits says.

“On the plus side, the CNDCP initiative signals acceptance in the AI sector about the demand from regulators for them to report more,” he says. “On the downside, the opposition from NGOs and local governments to AI operators being involved in setting standards shows a high level of distrust toward the industry.”

 

Companies should expect requirements to report on their AI-related risks and impacts to tighten in the future

THE PUSH FOR TRANSPARENCY

Corporate AI users are uniquely positioned to intervene, leveraging their commercial relationships with AI providers to push them to make their datasets more open. At the same time, by making public their requests, companies can signal their intent to be transparent and get ahead of criticism or distrust about their AI-related impacts.

Reporting on AI-use impacts isn’t easy. Standards remain inconsistent, legal requirements are still evolving, and (most significantly) auditable data is fragmented and hard to come by. Nonetheless, getting themselves ready to report is a task all companies must confront.

KEY TAKEAWAYS

  • GenAI tools are driving a massive uptick in business spend on AI software, turning AI use into a significant driver of global water and electricity use.
  • AI’s water and electric dependencies come with growing ecological costs. Although primary responsibility for these costs falls on AI owners, business users are not exempt.
  • To strengthen their environmental credibility, companies should prepare to disclose their true AI-use footprint. Acting now is the best way to get ahead of future regulation.
  • Greater visibility into companies’ AI footprint can prompt innovation and create resilience, including opportunities to deploy sustainable solutions to reduce AI-related risks and dependencies.
  • Companies should start by conducting an inventory of their AI use, which provides a baseline that can be used to set targets and stress-test against future scenarios.
  • Obtaining this data may require companies to directly engage with AI providers, and factoring disclosure into AI purchasing agreements can be a powerful lever here.
