UK Datacentre Threatens Net Zero Goals

A proposed "hyperscale" datacentre, the East Havering Data Centre Campus (EHDCC), in North Ockendon is facing significant opposition due to its projected environmental impact. Planning documents indicate the facility could emit over 1.2 million tonnes of carbon dioxide equivalent (CO2e) annually once fully operational. This volume of emissions is equivalent to approximately 27,000 long-haul flights from London to New York.

The EHDCC project, developed by Digital Reef, is planned for a 218-hectare site and has been described by its developer as a "sustainable datacentre campus of the future." However, the developer's own documents state the £14.7 billion project "does not align with a science-based 1.5C compatible trajectory and achieving net zero by 2050." Over its 60-year lifespan, the development is estimated to generate more than 72 million tonnes of CO2e.

Concerns extend to the datacentre's energy demands, with Digital Reef estimating it would consume 2.65 billion kWh per year at a 50% load. This usage is comparable to the annual electricity demand of over one million UK households. The campus plans a substantial connection to the National Grid, necessitating major upgrades to local substations, with the full connection anticipated by 2033.

The scale of projected emissions from datacentres like EHDCC raises critical questions about reconciling the UK's rapid AI infrastructure expansion with its legally binding climate targets. By 2038, the EHDCC's operational emissions alone are predicted to consume nearly 20 times the entire carbon budget of the Havering borough and almost 1% of the UK's total carbon budget.
