The Glebelands Alliance is a campaign group formed to raise awareness of an alleged unlawful development at the Glebelands hazardous waste landfill site in St Julians, Newport, South Wales.

The Glebelands Alliance was formed when Newport Friends of the Earth and Chepstow Friends of the Earth teamed up with the long-standing 'Glebelands Action Group' - a local residents group that was formed in the 1990s (formally 'Save The Glebelands').

The Glebelands Alliance is seeking justice in the environmental matters arising from development of the Glebelands site.

Newport council, with the support of the Welsh Assembly Government (WAG), granted planning permission for residential houses and the Glan Usk Primary School to be built on top of this severely contaminated site without the benefit of an Environmental Impact Assessment.

The Glebelands Alliance alleges that the original planning permission and subsequent planning permission amendments were unlawful, and that remediation of the contaminated land was botched. For example, no attempt was made to find the source of elevated radiation measurements recorded at the site prior to building Glan Usk Primary School.  In addition, there remains an open drainage ditch ('Lotery's Reen') that cuts across the contaminated site and empties directly into the River Usk SSSI and SAC which, in turn, flows into the Severn Estuary SPA.

Requests to revoke planning permission have been submitted to Newport council and to the Welsh Assembly Government.  Complaints about the lack of Environmental Impact Assessment for this development have been submitted to both the European Commission and the European Ombudsman.
