We recognise that CAZs do not address the root causes of air pollution, nor the wider issues beyond their boundaries, and that local leaders sometimes have to strike a difficult balance so as to not “lose the dressing room”. However, at times local government also needs to be prepared to push through CAZs and related actions, despite local opposition. They will be assisted in doing so by having clear evidence of the positive difference such interventions can have for local people and economies. The JAQU should work with local authorities and interested charities to review the scope and accessibility of its evaluation programme, to ensure that it can be used effectively at a local level to design new interventions and build support for them.
