Trees can help to cool cities by taking the pressure off air conditioning, the Forestry Commission has suggested. The study, carried out with the Department for Environment, Food and Rural Affairs, found that an area with heavy foliage is up to 4C cooler than a comparative area with little foliage. By selecting trees such as the sessile oak, the cherry and London plane, which are best at cooling, the use of air conditioning could be reduced by 13 per cent, the study said. Such trees should be planted in an area where it is possible for people to walk or sit under them and extra foliage should be planted in a way that shades homes and buildings. Replacing air conditioning with trees could save £22 million a year by reducing energy consumption and so lessen the carbon footprint of cities.
