The Environmental Footprint of AI

AI models, particularly large-scale machine learning systems like generative AI, require enormous computational resources. Training these models involves performing billions or even trillions of calculations, which consumes substantial electricity. Much of this energy still comes from fossil fuel-based power plants, leading to significant carbon dioxide emissions.

Key statistics from 2025:

The global AI industry was estimated to consume hundreds of terawatt-hours of electricity, comparable to the annual consumption of some small countries.
Associated CO2 emissions increased sharply, contributing to climate change pressures already exacerbated by industrial and transportation sectors.
Water usage surged due to the cooling requirements of massive data centers housing AI supercomputers. Estimates indicate millions of liters of water per day used for cooling in AI-intensive regions.

Causes Behind the Environmental Surge

Several factors contributed to the environmental crisis in 2025:

1. Exponential Model Growth

AI models have grown exponentially in size and complexity. Mega-models with hundreds of billions of parameters are now the norm, requiring extended training sessions on specialized GPU clusters. This results in prolonged high-power usage, often sustained for weeks or months.

2. Data Center Expansion

The AI boom has fueled a rapid expansion of data centers globally. New facilities are often located in regions with cheap electricity, but without sufficient renewable energy integration, reliance on fossil fuels remains high.

3. Increased Cloud Computation Demand

Companies and governments are outsourcing AI computation to cloud providers. The surge in demand has pushed data centers to operate near maximum capacity, further increasing energy consumption and associated emissions.

4. Inefficient Cooling Systems

Advanced AI hardware generates enormous heat. In 2025, many facilities relied on water-intensive cooling systems, consuming vast quantities of freshwater, especially in areas already facing water scarcity.

Case Studies: Regions and Industries Most Affected

North America

The United States, home to major AI companies, experienced one of the highest jumps in energy demand. Several large AI training clusters contributed millions of tons of CO2 emissions annually, prompting calls for greener data center policies.

Asia

China and India, rapidly adopting AI technologies, faced critical water shortages linked to AI data centers. The water-intensive cooling systems strained local freshwater sources, affecting communities and agriculture.

Europe

While Europe prioritized renewable energy integration, regions with AI hubs still reported increased energy usage. Policymakers called for stricter AI sustainability regulations to align with climate goals.

Industrial Applications

AI-driven automation and predictive analytics in manufacturing, logistics, and agriculture intensified electricity use. The environmental cost of these AI-enhanced efficiencies was substantial, sometimes negating the expected sustainability benefits.

The Hidden Carbon Cost of AI Training

A single large AI model training session can emit hundreds of tons of CO2, equivalent to the lifetime emissions of multiple cars. Key factors influencing carbon emissions include:

Hardware efficiency: Older GPUs and CPUs consume more energy.
Model size: Larger models require more computational cycles.
Training duration: Weeks-long training sessions amplify energy usage.
Energy source: The proportion of fossil fuels versus renewable energy determines net emissions.

This hidden carbon footprint is often overlooked in discussions about AI’s societal benefits, creating a trade-off between technological progress and ecological sustainability.

Water Usage Crisis Linked to AI

Water plays a crucial role in cooling high-performance computing systems. In 2025, reports indicated:

Major AI data centers consumed millions of liters of water daily.
Water scarcity regions hosting AI clusters experienced increased competition between industrial, agricultural, and residential needs.
Evaporative cooling systems contributed to localized humidity changes and stress on freshwater ecosystems.

Environmentalists have warned that without sustainable cooling alternatives, water usage by AI could exacerbate droughts and strain vital water resources globally.
