Mini forest and ‘green tower’ plans among first to meet London’s new green guidelines
Developers will consider contribution to environment using Urban Greening Factor formula.
The Urban Greening Factor (UGF) formula, inspired by the Swedish city of Malmö’s “green points” system, scores each part of a development’s plan – including street-level areas, balconies and roofs – from 0 to 1, with trees, planters and green roofs earning high scores, while paving slabs and barren rooftops receive no score. Central government has also set out plans in the Environment Act 2021 to make developments deliver an uplift to biodiversity, which will require a 10% “biodiversity net gain”.
