AI sustainability refers to the development, deployment, and management of artificial intelligence in ways that reduce environmental harm while supporting technological progress. It considers the environmental impact of training AI models, operating data centres, manufacturing computer hardware, and managing electronic waste.

One of the most important concerns is the electricity required by AI data centres. Large language models and advanced machine learning systems depend on powerful processors, specialised graphics processing units (GPUs), storage infrastructure, and cooling equipment. These systems operate continuously and can create significant energy demands.

The relationship between artificial intelligence and environmental sustainability is therefore complex. AI can increase electricity consumption, but it can also help organisations improve energy efficiency, manage renewable electricity, monitor pollution, and optimise industrial operations.

Understanding both sides is essential for evaluating the long-term environmental impact of AI.

Why AI Sustainability Matters Today

AI sustainability has become an important topic because the global expansion of artificial intelligence is increasing demand for computing infrastructure. Technology companies, governments, research institutions, and energy providers must consider how to support this growth without creating unnecessary environmental pressure.

Increasing Electricity Demand

AI data centres require electricity to operate servers, networking equipment, storage systems, and cooling infrastructure. Training large AI models can involve thousands of specialised processors working simultaneously.

Electricity demand is influenced by several factors:

• The size and complexity of AI models.

• The number of training and inference operations.

• Data centre efficiency and cooling requirements.

• The availability of renewable electricity.

• The frequency of AI applications and user requests.

As AI adoption expands, electricity planning becomes increasingly important for data centre operators and national energy systems.

Carbon Emissions and Climate Change

Electricity generation remains a major source of global greenhouse gas emissions in many regions. When data centres depend on electricity generated from coal, natural gas, or other fossil fuels, their operations can contribute to carbon emissions.

The environmental impact also extends beyond electricity consumption. Manufacturing semiconductors, constructing data centres, transporting equipment, and disposing of outdated hardware require materials and energy.

Carbon accounting helps organisations understand these impacts throughout the technology lifecycle.

Water Consumption and Cooling Systems

High-performance computing equipment generates heat during operation. Data centres use different cooling technologies to maintain suitable temperatures and protect hardware.

Some facilities use water-based cooling systems, which can place pressure on local water resources, particularly in areas experiencing water scarcity.

Efficient cooling methods include:

• Direct liquid cooling.

• Improved airflow management.

• Heat recovery systems.

• Advanced temperature monitoring.

• Cooling technologies designed for local climate conditions.

AI as a Sustainability Tool

AI can also support environmental improvements across different industries.

These applications demonstrate that AI can contribute to sustainability when its environmental benefits are evaluated alongside its computing requirements.

Recent Developments in AI Sustainability and Energy Efficiency

The period from late 2025 through 2026 has brought increased attention to the relationship between artificial intelligence, electricity demand, data centre infrastructure, and environmental responsibility.

Rising Global Data Centre Electricity Consumption

The International Energy Agency (IEA) reported in its 2026 analysis that global data centre electricity consumption increased by 17% in 2025. Electricity consumption from AI-focused data centres increased by approximately 50%.

The IEA estimates that total data centre electricity consumption could rise from approximately 485 terawatt-hours (TWh) in 2025 to 950 TWh by 2030.

This development highlights the importance of:

• Improving data centre energy efficiency.

• Expanding renewable electricity generation.

• Developing efficient AI processors.

• Improving electricity grid infrastructure.

• Monitoring the environmental impact of computing operations.

Advances in Liquid Cooling Technology

Traditional air-conditioning systems are increasingly being supplemented by advanced cooling technologies designed for high-density computing environments.

Direct-to-chip liquid cooling transfers heat away from processors through specialised cooling systems. Immersion cooling places computing equipment in specially designed cooling fluids.

These technologies can help manage heat more effectively and may reduce cooling-related energy requirements, depending on system design and operating conditions.

Renewable Energy Integration

Technology companies and data centre operators are increasingly exploring renewable energy procurement to support expanding computing infrastructure.

Solar, wind, hydropower, battery storage, and other low-carbon electricity sources are becoming important considerations in data centre planning.

The IEA's 2026 analysis also highlighted increased renewable electricity agreements by major data centre operators. During the first half of 2026, operators signed approximately 45 TWh of power purchase agreements, nearly 20% more than during the same period in 2025.

More Attention to Environmental Measurement

Environmental reporting is becoming an important part of AI infrastructure planning. Organisations are increasingly examining indicators such as:

• Power Usage Effectiveness (PUE).

• Water Usage Effectiveness (WUE).

• Carbon Usage Effectiveness (CUE).

• Total electricity consumption.

• Renewable electricity percentage.

• Hardware utilisation rates.

These measurements help organisations understand whether improvements in computing efficiency are translating into lower environmental impact.

India's Growing AI Infrastructure

India is expanding its data centre ecosystem to support artificial intelligence, cloud computing, and digital infrastructure.

In March 2026, the Indian government reported that national data centre capacity had increased from approximately 375 MW in 2020 to around 1,500 MW by 2025. It also reported that 38,231 GPUs had been onboarded through the IndiaAI compute framework.

The development highlights the need to balance AI infrastructure expansion with electricity planning, water conservation, and energy-efficient computing.
