Former government Chief Scientific Adviser and Director of Smith School of Enterprise and the Environment, Oxford
"I fully support Close the Door as there is an urgent need to do everything we can to reduce carbon emissions. UK business is in many ways prepared to lead the way and in asking retailers to close their door while using heating or air conditioning, this campaign addresses an area of waste that we often overlook. It is an easy and effective way to cut energy waste and I encourage both retailers and customers to support it."
