Policy G2 London's Green Belt


  1. The Green Belt should be protected from inappropriate development:
    1. development proposals that would harm the Green Belt should be refused
    2. the enhancement of the Green Belt to provide appropriate multi-functional uses for Londoners should be supported.
  2. The extension of the Green Belt will be supported, where appropriate. Its de-designation will not.

The Mayor strongly supports the continued protection of London’s Green Belt. The NPPF[1] provides a clear direction for the management of development within the Green Belt and sets out the processes and considerations for defining Green Belt boundaries. London’s Green Belt makes up 22 per cent of London’s land area and performs multiple beneficial functions for London, such as combating the urban heat island effect, growing food, and providing space for recreation. It also provides the vital function of containing the further expansion of built development. This has helped to drive the re-use and intensification of London’s previously developed brownfield land to ensure London makes efficient use of its land and infrastructure, and that inner urban areas benefit from regeneration and investment.

Openness and permanence are essential characteristics of the Green Belt, but despite being open in character, some parts of the Green Belt do not provide significant benefits to Londoners as they have become derelict and unsightly. This is not, however, an acceptable reason to allow development to take place. These derelict sites may be making positive contributions to biodiversity, flood prevention, and reducing the urban heat island effect. The Mayor will work with boroughs and other strategic partners to enhance access to the Green Belt and to improve the quality of these areas in ways that are appropriate within the Green Belt.
