A system of water credits for housing developers to build up to 150,000 homes in water-stressed Cambridge has been set out by government to sidestep objections to new homes. The plan to address water scarcity was unveiled jointly by the Department for environment (Defra), Environment Agency and the Department for levelling up and the local planning authority for Cambridge. The proposed water credit pilot would allow developers to offset the water consumption of new homes by buying credits to have a neutral impact on overall resources in the area.
