Bridging the awareness gap: the urgent need for sustainability and literacy in AI-driven data centres

A recent analysis highlights how growing reliance on AI and digital infrastructure exacerbates environmental and health challenges, emphasizing the need for improved public understanding and sustainable industry practices.

At a recent book fair, a parent expressed concern about the data centre industry’s environmental footprint, AI’s rise, and its societal ramifications. Yet, paradoxically, she had just upgraded a phone and laptop with an unlimited data plan, highlighting a widespread disconnection between digital consumption habits and awareness of the infrastructure sustaining them. This encounter underscores a strategic challenge in the data centre sector: while public reliance on digital services grows, understanding of the physical and environmental costs remains limited.

As digital infrastructure professionals note, this disconnect has tangible consequences. Community resistance to new data centre developments, talent shortages in infrastructure operations, and planning frustrations all stem from a lack of infrastructure literacy. Despite AI features being integrated into daily life, from voice assistants to social media algorithms, the public discourse often frames AI abstractly or as a threat, ignoring the substantial computing power AI requires. As a result, facilities essential for digital life are viewed as impositions rather than enablers. Industry leaders emphasize that addressing these challenges through education is crucial for operational risk management, recruitment, and fostering community support.

The environmental impact of AI-powered data centres is becoming increasingly urgent. A United Nations report by the International Telecommunication Union reveals that indirect carbon emissions from major AI-focused tech giants, Amazon, Microsoft, Alphabet, and Meta, have surged by approximately 150% between 2020 and 2023. This rise is driven primarily by the energy consumption of data centres powering AI technologies. The report warns that growing AI investments could produce over 100 million tons of carbon dioxide equivalent emissions annually, significantly surpassing global electricity consumption growth rates. Despite pledges to reduce emissions, substantial reductions have yet to materialize, underscoring the growing strain AI places on energy infrastructure.

Beyond carbon emissions, the broader environmental and public health impacts merit attention. Research indicates that the lifecycle of AI, from chip manufacturing to data centre operation, generates substantial air pollution, including fine particulate matter that impairs public health. One study quantifies that training an AI model of the Llama 3.1 scale emits pollutants equivalent to over 10,000 round trips between Los Angeles and New York by car. The health costs associated with U.S. data centres projected for 2030 could exceed $20 billion annually, doubling the health burden of coal-based steelmaking and disproportionately affecting economically disadvantaged communities. These findings highlight the need for standardised reporting on pollutants and health impacts, and for AI development to incorporate public health considerations.

The rapid expansion of data centres, especially in the U.S., intensifies these environmental challenges. Detailed data from 2,132 U.S. data centres show they consume over 4% of total U.S. electricity, with more than half sourced from fossil fuels, leading to emissions of more than 105 million tons of CO₂ equivalent. These centres have a carbon intensity 48% higher than the U.S. average, revealing the considerable environmental cost of digital infrastructure supporting AI and related services.

Energy consumption by AI systems is notably high due to the resource-intensive processes required for training and inference in large language models. For example, training GPT-4 is estimated to have used roughly 50 gigawatt-hours, enough energy to power a city like San Francisco for several days. The inference stage, despite being less demanding per query, becomes energy-intensive given the billions of daily requests AI chatbots handle. AI-driven data centres are responsible for about 4.4% of U.S. electricity usage as of 2023 and contribute to around 1.5% of global energy consumption, a figure projected to double by 2030. Despite ongoing research efforts to reduce AI’s energy footprint, limited transparency from major tech firms hampers comprehensive understanding and hinders energy efficiency initiatives.

Industry experts caution that if AI models are not designed efficiently, their energy demands could be immense. Training large models can consume electricity comparable to hundreds of households annually. Projections suggest that by 2030, data centres globally might consume electricity equivalent to the combined usage of countries like Japan and Germany, highlighting the scale of the challenge. This calls for concerted innovation in design and operational efficiency within the sector.

Beyond environmental costs, the broader climate implications are considerable. AI, as part of the information and communications technology sector, currently accounts for at least 1.7% of global emissions. However, this figure may underrepresent future impact, as AI adoption accelerates alongside expanding digital penetration, cloud services, and blockchain technologies. The International Energy Agency estimates that data centre electricity consumption could reach 1,000 terawatt-hours by 2026, a 400% increase since 2022. Recent disclosures from companies like Google and Microsoft reflect year-on-year emission increases, posing challenges to their climate commitments despite ongoing efforts to innovate sustainable solutions.

Ultimately, closing the gap between public understanding and the realities of digital infrastructure is vital. Developing infrastructure literacy can reduce community opposition, expand talent pipelines, and improve stakeholder engagement. Simultaneously, transparent reporting on environmental and health impacts, alongside technological innovation, is essential to mitigate the growing pressures that AI and data centres place on energy consumption and the environment. This dual approach, educating communities and advancing sustainable practices, forms the strategic foundation for balancing the benefits of AI with its unseen costs.
