Motion detail

Leonie Cooper AM moved, and James Small-Edwards AM seconded the following motion:

"This Assembly notes the benefits of biodiversity net gain, including London’s pioneering work in this area which became a blueprint for national legislation. The Assembly further notes the benefits of the urban greening factor, which has introduced the benefits of nature to many parts of London previously denied it. 

The Assembly also acknowledges London’s acute housing crisis and the need to build 888,000 new homes in the next decade. The Assembly recognises the green belt’s contribution towards biodiversity and notes the Mayor’s comments that the green belt is the “lungs of the capital” and “as important today as it always has been”.

The Assembly further notes the consultation on the update to the London Plan and agrees that through biodiversity net gain and the urban greening factor, the city can continue to increase the amount of incredible nature within its boundaries.  These developments must be nature-friendly, incorporating biodiversity net gain and meeting the urban greening factor as we address London’s housing crisis. 

This Assembly therefore calls on the Mayor to launch a campaign to widely publicise the benefits of biodiversity net gain and the urban greening factor in increasing London’s accessible nature, including how it will be used in all new developments."

Following debate, and upon being put to a vote, this motion was agreed unanimously.
