NEW DELHI (February 28, 2026) — Martin Krause, the Director of the Climate Change Division at the United Nations Environment Programme (UNEP), has warned that while Artificial Intelligence (AI) is a powerful tool for combating the climate crisis, its massive resource consumption poses a significant environmental threat. Speaking in an interview with PTI Videos following the India AI Impact Summit, Krause emphasized that “guardrails” are essential to ensure AI does not deplete the very natural resources it is meant to protect.
The “Opportunity”: AI as a Climate Solution
Krause highlighted several critical areas where AI is already delivering measurable benefits for climate adaptation and mitigation:
- Early Warning Systems: AI is dramatically improving the accuracy of predictions for floods and storms. If deployed at scale, these systems could protect hundreds of millions of people in vulnerable regions.
- Grid Integration: In countries like India, AI is being used to recalibrate and balance national grids as they integrate increasing amounts of intermittent renewable energy like solar and wind.
- Emission Tracking: Satellite-based AI tools are now capable of pinpointing and tracking methane and other greenhouse gas emission sources in real-time, allowing for faster regulatory and corrective responses.
The “Risk”: Energy and Water Strain
The “negative side” of the AI explosion lies in its heavy physical infrastructure. Data centers required to train and run large-scale AI models are among the most resource-intensive facilities on the planet.
- Energy Demand: Data center electricity consumption is expected to more than double between 2022 and 2026, potentially surpassing 1,000 TWh globally. In some tech hubs like Ireland, AI could account for 35% of national energy use by 2026.
- Water Consumption: Large data centers can consume up to 5 million gallons of water daily—equivalent to the needs of a town of 50,000 people—primarily for cooling electrical components.
- Resource Depletion: Krause warned that without site-specific assessments and a shift to clean power, these centers risk “shifting costs to vulnerable communities” by straining local water tables and increasing fossil fuel emissions.
Global Policy and “Guardrails”
The UN is increasingly treating AI sustainability as a distinct environmental issue. In December 2025, the United Nations Environment Assembly (UNEA-7) adopted its first-ever resolution on the Sustainable Use of Artificial Intelligence.
“The key point is that there must be guardrails to ensure that, while AI and data centres bring significant benefits, they do not end up depleting the scarce natural resources we all depend on.” — Martin Krause, UNEP
During the recent summit in Delhi, UN Secretary-General António Guterres echoed these concerns, urging tech leaders to ensure data centers switch to clean energy rather than relying on carbon-heavy power sources that exacerbate the climate emergency.
