Green Infrastructure
Cadogan | Chelsea 2030
10
Improving the quality and quantity of greening across Chelsea is a core target of Chelsea 2030, due to the range of environmental and social benefits provided by access to nature – including improved air quality, carbon absorption, flood regulation, pollination support as well as significant mental health benefits3.
Target 5 25% increase in Estate Urban Greening Factor by 2030
F
rom a baseline of an estate-wide Urban Greening Factor4 of 0.18, in 2021 we saw a 12% increase to 0.2 and an additional 300m2 of green space. This was achieved through a combination of groundcover planting in Gardens, biodiverse tree-pit replanting in Duke of York Square and Pavilion Road, and Pont Street’s ‘pocket forest’. Our garden management is inherently biodiversity-friendly; from the absence of chemicals to the focus on native
species, wildflowers and fruit and nut trees, bird boxes and bug hotels. To find out more about the biodiversity of our grass lawns and soils, we are proud to be taking part in a project led by the Natural History Museum, using the innovative approach of eDNA testing5 to build greater understanding of the biodiversity value of urban lawns. Future projects will include retrofitting green roofs to our Estate, increasing biodiverse planting and integrating greening into our developments: from 1,600m2 green roof in the new development at 196-222 King’s Road, to planting over 90 trees on Sloane Street as part of the public realm improvement works.
