AI’s growing demand for resources is unsustainable; NTT DATA paper calls for action and offers solutions

• White paper shows how AI can help solve the environmental challenges it creates
• Resource efficiency should be designed into systems from the start
• Sustainable AI requires lifecycle thinking and circular-economy principles

TOKYO and LONDON – October 28, 2025–A new white paper from NTT DATA, a global leader in AI, digital business and technology services, highlights the urgent need to embed sustainability into every layer of AI development and deployment to counteract the technology’s environmental impact. Deploying innovative solutions for sustainable AI is a corporate responsibility and a strategic opportunity to create lasting value, build organizational strength and consume fewer essential resources.

The new paper, Sustainable AI for a Greener Tomorrow, illustrates the growing environmental impact of AI and outlines a path to sustainable innovation. The technology requires enormous volumes of electricity to support surging computational demands to train large language models, run inference pipelines and maintain always-on services. Researchers predict AI workloads will drive more than 50% of data center power consumption by 2028. Other primary environmental impacts include water consumption for data center cooling systems, e-waste and rare earth mineral extraction for hardware production.

“The resource consequences of AI’s rapid growth and adoption are daunting, but the technology also can empower innovative solutions to the environmental problems it creates,” said David Costa, Head of Sustainability Innovation Headquarters, NTT DATA. “AI’s amazing capabilities can help manage energy grids more efficiently, reduce overall emissions, model environmental risks and improve water conservation. It’s vital for organizations to recognize the challenge and build sustainability into AI systems from the start.”

Key Insights

• Expand From Performance to Green Priorities: NTT DATA’s AI experts and sustainability consultants urge the use of holistic sustainability goals, not just conventional AI performance metrics such as accuracy and speed. Efficiency must be prioritized, not as a trade-off, but as a core design principle.

• Quantify Environmental Impact: AI’s energy consumption, carbon emissions and water footprint need standard and verifiable metrics. Industry benchmarks such as the “AI Energy Score” and “Software Carbon Intensity (SCI) for AI” offer ways to embed sustainability into governance, procurement and compliance protocols.

• Lifecycle-Centric Approach: Sustainable AI requires lifecycle thinking, from raw material extraction and hardware production to system deployment and ultimate disposal. Important steps include lengthening hardware lifespans, optimizing cooling systems and applying circular-economy principles.

• Shared Accountability Across the Ecosystem: Responsibility is widely distributed, encompassing hardware manufacturers, data center operators, software developers, cloud providers, policymakers, investors and consumers. Cross-sector cooperation is essential for systemic change.

Barriers and Best Practices

Today, fragmented assessments and inconsistent metrics frequently prevent meaningful benchmarking. Many organizations focus narrowly on energy or emissions without considering water usage, rare material depletion and e-waste. These and other factors must be addressed comprehensively. Even when environmental goals are set, organizations often lack actionable methods to apply sustainability at every stage of the AI lifecycle.

To address these and other concerns, the report outlines numerous best practices, including:

• Applying green software engineering patterns to reduce resource consumption
• Running AI workloads in locations and at times that align with renewable energy availability
• Leveraging remote GPU Services and on-premises AI
• Reducing e-waste by prioritizing modular and upgradable components, and extending hardware lifespans through refurbishment, reuse and responsible recycling

While the road to sustainable AI is complex, an intentional, end-to-end redesign of the AI lifecycle can help fulfill this technology’s positive potential while protecting the environmental systems on which all living things depend.
