All London Green Grid
The All London Green Grid (ALGG) is a policy framework to promote the design and delivery of ‘green infrastructure’ across London. Green infrastructure can be defined as:
A network of green spaces - and features such as street trees and green roofs - that is planned, designed and managed to provide a range of benefits, including: recreation and amenity, healthy living, reducing flooding, improving air quality, cooling the urban environment, encouraging walking and cycling, and enhancing biodiversity and ecological resilience.
The policy framework comprises London Plan policies on green infrastructure and urban greening - and those relating to open spaces, biodiversity, trees & woodland, and river corridors - plus the All London Green Grid Supplementary Planning Guidance and a series of ALGG Area Frameworks.
