A letter coordinated by the UK Green Building Council (UKGBC), co-signed by Core Cities UK and UK100 has urged the government to give local authorities the freedom to set higher sustainability standards in new homes. Released on Thursday 10 May, the letter is timed to coincide with the consultation closing for the revised National Planning Policy Framework (NPPF). The letter proposes new wording of the NPPF as well as a new Ministerial Statement to provide confidence and clarity. John Alker, Director of Policy and Places at UKGBC said: “At a time of devolution and city leadership on climate change and sustainability, it seems perverse to artificially stifle the ambition of local authorities, who are working together to move forward collectively and consistently”.
