A pause on building AI datacentres is off the table, after Labour rejected Green leader Zack Polanski’s call to "slam the brakes" on new projects. Polanski proposed a moratorium on what he described as "energy-guzzling" AI developments, but ministers and party strategists have ruled the measure unacceptable.

The government framed the proposed ban as an economic threat, saying a moratorium would be a disaster for the economy. That assessment underpins Labour’s decision and signals continued official resistance to any policy that would halt datacentre construction on energy-use grounds.

Labour’s refusal leaves the Green Party’s demand without the governing party’s support, narrowing the political path for immediate statutory action. The outcome preserves current policy momentum for datacentre projects and keeps the industry’s near-term development prospects intact, at least for now.

The dispute lays bare a fault line between environmental concern over the energy footprint of large-scale AI infrastructure and the government’s priority on economic stability. By couching the moratorium in stark economic terms, ministers have raised the political cost for any party that seeks to press for an outright ban.

For the Green leadership, the rejection is a setback that will require either fresh arguments or alternative policy levers to shift opinion. For Labour, accepting the government framing avoids a showdown over industrial strategy and energy policy during a sensitive political period.

The debate over the energy implications of AI datacentres and the pace of their rollout will continue. Labour’s decision means the immediate prospect of a moratorium has receded, while the underlying tensions between environmental objectives and economic arguments remain unresolved, leaving the issue open to further political contestation.Reported by theguardian.com.
