A \u201chyperscale\u201d datacentre in outer London<\/a> would generate more than 1m tonnes of carbon dioxide a year, equivalent to the carbon footprint of 27,000 flights from London to New York, planning documents show.<\/p>\n

The East Havering Data Centre Campus (EHDCC) in North Ockendon would be one of the largest datacentres in Europe if approved by Havering council, using 218 hectares of green belt to run servers and data storage systems for AI and cloud computing. Its developer, Digital Reef, has described the scheme as \u201ca unique opportunity to create a sustainable datacentre campus of the future\u201d.<\/p>\n

But in the planning application, Digital Reef says the \u00a314.7bn project \u201cdoes not align with a science-based 1.5C compatible trajectory and achieving net zero by 2050\u201d. Documents estimate the development would generate more than 72m tonnes of carbon dioxide<\/a> equivalent (CO\u2082e) over its projected 60-year lifespan \u2013 1.2m tonnes annually once fully operational.<\/p>\n

Guardian analysis of planning documents for the dozens of proposed datacentres in the UK shows that the EHDCC has the highest projected carbon emissions disclosed by a developer.<\/p>\n

Donald Campbell, advocacy director at the tech justice nonprofit Foxglove, said the EHDCC\u2019s projected emissions were \u201cstaggering\u201d.<\/p>\n

\u201cIt\u2019s a big threat to the ability to decarbonise in the UK,\u201d he said. \u201cIt\u2019s also going to be a big drain on important resources that are needed by homes and other businesses.\u201d<\/p>\n

According to Ofgem, the average UK household electricity consumption is 2,500 kWh per year. Digital Reef said in its proposal that at a \u201clikely\u201d 50% load, the campus would consume 2.65bn kWh per year of electricity, equivalent to the demand of more than 1m UK households.<\/p>\n

The campus would be powered primarily by a huge 600MVA connection to the National Grid via the nearby Warley substation. Because the existing site does not have sufficient capacity, major upgrades are planned, including a new 400kV National Grid substation and a new 132kV UK Power Networks facility on adjacent land, with the full connection expected by 2033.<\/p>\n

The 1.2m tonnes of CO\u2082e the EHDCC expects to emit would amount to 26,795 long-haul flights from London Heathrow to New York\u2019s John F Kennedy international airport, according to the UN\u2019s International Civil Aviation Organization\u2019s carbon calculator<\/a>.<\/p>\n

North Ockendon Residents Association said the development would be a \u201cmassacre\u201d of green belt land. \u201cIt\u2019s crop-producing farmland, in an age when we are threatened by security, it\u2019s the loss of wildlife habitats, and there\u2019s the pollution cost, which everyone seems to brush under the carpet,\u201d a group spokesperson said.<\/p>\n

The scale of datacentre emissions raises questions over how Britain\u2019s rapid expansion of AI infrastructure can be reconciled with the government\u2019s legally binding climate targets<\/a>.<\/p>\n

The government designated datacentres as \u201ccritical national infrastructure\u201d in 2024, putting the tech developments on an equal footing with water, energy and emergency services systems.<\/p>\n

By early 2025, the government estimated datacentres used 2.5% of the UK\u2019s electricity<\/a>, but predicted this would increase fourfold by 2030.<\/p>\n

In January, planning legislation was amended<\/a> so datacentre developers were able to apply as nationally significant infrastructure projects, meaning they were able to largely bypass the local authority planning procedure and seek approval directly from government.<\/p>\n

Neso, Britain\u2019s grid operator, has warned MPs that datacentre developers have requested 72.8GW of electricity connections<\/a> by 2039 \u2013 a \u201chuge step change for the sector\u201d and nearly 60% more than the UK\u2019s peak power demand last year<\/a> \u2013 in a surge driven by the race to build AI and hyperscale infrastructure.<\/p>\n

The government said last year<\/a> the now disbanded department for science, innovation and technology (DSIT) would produce a national policy statement for the sector, but it has not yet been published.<\/p>\n

Campbell said: \u201cThe government needs to be taking concrete steps to make sure that the public and the environment aren\u2019t left to carry the social environmental costs of the datacentres. These datacentres are ultimately going to be serving the wealthiest companies in the world \u2013 so they need to be required to carry that cost.\u201d<\/p>\n

By 2038, the EHDCC operational emissions alone are projected to consume nearly 20 times the entire carbon budget of the borough of Havering and almost 1% of the UK\u2019s entire carbon budget.<\/p>\n

Planning documents said that where the zero-carbon target cannot be met on site, \u201cany shortfall would be provided through a cash in lieu contribution to the borough\u2019s carbon offset<\/a> fund\u201d. The developer estimates that payment at about \u00a377.6m.<\/p>\n

Campbell said datacentre developers should at a minimum be required to build enough additional renewable generation and storage to supply their facilities. \u201cThat\u2019s the only way of really ensuring that it\u2019s not going to add to carbon emissions,\u201d he said. \u201cThey shouldn\u2019t just plug into the grid and drain the power that everyone else needs.\u201d<\/p>\n

The first round of consultation on the EHDCC closed in April. A revised proposal reflecting any accepted changes is expected to be published for a further public consultation in the autumn.<\/p>\n

Councillor Keith Prince, Reform UK leader of Havering council, said that as a decision on EHDCC is made by the local planning authority, it would be \u201cwrong\u201d to comment until that decision was made.<\/p>\n
