The Urban Greening Factor (UGF) originates from Berlin and has been adapted and adopted in several European and North American cities. A planning policy tool evaluates the quantity and quality of urban greening provided by a development proposal [6]. The UGF aims to accelerate the greening of urban areas and ensures well planned and high-quality interventions that add to a multi-functional green infrastructure network. This policy means green infrastructure is considered at the start of the design and planning process for new developments and buildings[7]. The UGF is set out in Policy G5 of the New London Plan and provides a simple way for Local Planning Authorities to score green infrastructure interventions[8].
