Introduction
The United Kingdom stands at the forefront of the artificial intelligence (AI) revolution, with ambitious plans to bolster its digital infrastructure. Central to this vision is the proposed £10 billion Elsham AI data centre in Lincolnshire. While this development promises significant economic and technological benefits, it also raises pressing environmental concerns, particularly regarding its substantial carbon footprint.
The Elsham Data Centre Project
The Elsham AI data centre, planned near Scunthorpe, is set to become one of the UK’s largest digital infrastructure projects. Spanning approximately 180 hectares, the facility will house 15 data centres with a combined IT load capacity of one gigawatt . Designed to meet the growing demand for AI processing power, the centre aims to position the UK as a global leader in AI technology.
However, the environmental implications are significant. At full operation, the data centre is projected to consume 3.7 billion kilowatt-hours of energy annually, resulting in approximately 857,254 tonnes of CO₂ emissions each year . This figure surpasses the emissions of Birmingham Airport by a factor of five, highlighting the potential environmental cost of the project.
Environmental Concerns and Criticisms

The substantial energy consumption and resulting emissions have drawn criticism from environmental groups and sustainability advocates. Martha Dark, co-executive director of Foxglove, a London-based non-profit, emphasized the conflict between the UK’s AI ambitions and its climate commitments. She questioned whether the government prioritizes economic growth over environmental responsibility, stating, “It’s decision time: does the government want an economic plan that’s best for Britain, or one that’s best for Amazon, Google, and Meta?” .
The developers have acknowledged the environmental concerns and expressed intentions to source green energy for the facility where possible. However, they have ruled out on-site renewable energy solutions, citing impracticalities. For instance, powering the centre with biomass would require 100 large lorry loads of wood chips daily, while wind energy would necessitate 10,000 20-meter turbines .
Global Context: AI’s Environmental Impact
The environmental challenges posed by the Elsham project reflect a broader global issue. A report by the International Telecommunication Union (ITU) revealed that indirect carbon emissions from major AI-focused tech companies—Amazon, Microsoft, Alphabet, and Meta—rose by an average of 150% between 2020 and 2023 . This surge is attributed to the energy-intensive nature of AI data centres, which require substantial electricity for both operation and cooling.
Furthermore, the University of York highlighted the “untold story” of AI’s environmental impact, emphasizing the high energy cost of our increasingly digital lives . As AI technologies become more integrated into various sectors, the demand for data processing and storage escalates, leading to increased energy consumption and associated emissions.
Potential Mitigation Strategies
To address these concerns, experts advocate for several mitigation strategies:
- Renewable Energy Integration: Prioritizing the use of renewable energy sources to power data centres can significantly reduce carbon emissions.
- Energy-Efficient Technologies: Implementing advanced cooling systems and energy-efficient hardware can lower overall energy consumption.
- Regulatory Measures: Governments can enforce stricter environmental regulations and incentivize sustainable practices within the tech industry.
- Transparency and Reporting: Mandating comprehensive reporting on energy usage and emissions can promote accountability and drive improvements.
The UK government has been urged to promote and invest in sustainable AI practices to become a global leader in AI frugality and efficiency . This includes extending mandatory reporting on AI’s energy and water use, carbon emissions, and e-waste recycling of data centres.

Conclusion
The Elsham AI data centre embodies the UK’s aspirations to lead in AI technology. However, it also serves as a stark reminder of the environmental challenges accompanying such advancements. Balancing technological progress with ecological responsibility is imperative. As the UK moves forward, integrating sustainable practices into digital infrastructure development will be crucial to ensuring a greener future.
