A new report highlighting the increasing number of green roofs in London has been launched by London’s deputy mayor for the environment.
The report reveals that the total area of green roofs in London is higher than other cities around the world which are well known for such developments, such as Copenhagen, Toronto and Singapore.
Launching the report Shirley Rodrigues, who was leading the Greater London Authority’s Environment Team when the first green roof policy was included in the London Plan in 2008, said she had been delighted to see green roofs and walls spreading across London’s skyline.
In the foreword, Shirley explains how – with the right policies, planning and governance – cities can be at the forefront of a more sustainable future.
“I have been delighted to witness the patchwork of green roofs and walls spreading across London’s skyline, alongside the establishment of a world-class industry that is working towards the greening of London,” she says.
The report, titled ‘Living Roofs and Walls from policy to practice – 10 years of urban greening in London and beyond’, was published by the European Federation of Green Roof and Green Wall Associations (EFB) and livingroofs.org on behalf of the Greater London Authority.
According to the latest available figures, 42% of the total UK green roof market is in London.
Written by Gary Grant and Dusty Gedge of The Green Infrastructure Consultancy, the report reveals that the total area of green roofs in the Greater London area is equal to 1.5 million m² with a density of 0.17m²per inhabitant. In the Central Activity Zone (CAZ) green roofs covered 290,000m², which equates to 1.26m²of green roof per inhabitant.
The new green roof report contains the first league table of green roof cities around the world and includes a review of global green roof policies and an appraisal of how various London boroughs are delivering green roofs.
The publication also includes 17 case studies of green roofs and walls in London, including three from one of London’s leading developers, Berkeley Group.
While the report recognises that it is primarily the planning system that has driven the uptake on green roofs, developers and businesses have also recognised the potential benefits to staff of providing roof top spaces. The roof garden at Nomura Bank is one such example.
Another new approach in the City is to create publicly accessible rooftop gardens, the first of which recently opened at 120 Fenchurch Street.
The report predicts that the provision of green roofs and walls on new developments across the whole of London will continue to grow.
