Agree in principle. However, the policy direction is towards taking into account the whole-life carbon emissions which are defined as emissions associated with constructing buildings. This needs to be expanded to include the carbon emissions associated with decontamination and demolition of existing buildings on the site, such as at the current Cambridge Waste Water Treatment Plant and the eventual demolition of the new building, ensuring that low carbon materials are used in construction and avoiding those with high carbon expenditure in their manufacture, e.g. cement.. This should include the carbon expenditure of Heavy Commercial Vehicles (HCVs) used to transport demolished building materials and the disposal of such materials with their embodied carbon.

Carbon expenditure, emissions and embedded carbon to decommission fully operational CWWTP and decontaminate site and build new plant within 1 mile of existing inclusive of transfer tunnels, HGV traffic etc., should be factored into carbon expenditure associated with fulfillment of S/NEC Policy
