London should be made up of 50% green infrastructure by 2050.
That’s according to a new report by the Green Infrastructure Task Force which suggests targets for the mayor by 2050.
It states ensuring half the city is made up of green buildings would allow it to maintain its status as “one of the world’s greenest capital cities”.
This would require an increase in green infrastructure of around 9000ha – three times the area of the London Borough of Haringey, it adds.
That could help the city be prepare for the potential impacts of a changing climate, it claims.
It also suggests London should maintain its “urban forest” by increasing tree cover from 20% to 30% – continuing to have one tree for every Londoner as the population grows.
The report adds 80% – or nine million – of Londoners should be walking, jogging or cycling at least two miles per day and surface water flows into the sewer network should be reduced by at least 25%.
Matthew Pencharz, Deputy Mayor for Environment & Energy, and Chair of the Task Force said: “To meet the challenge of a growing population, future investment in traditional infrastructure, public health programmes and regeneration, needs to include more green infrastructure-based solutions, so London continues to be recognised as one of the greenest and most liveable big cities in the world.”
