Greening the grey: Mayors Khan, Plante unveil C40 ‘rewilding’ guide for cities in London – C40 Cities

Restoring natural habitat in our cities can help to reduce impacts of climate change and improve the mental health and well-being of city dwellers

Restoring urban nature can help to mitigate the worsening effects of climate change with rising temperatures and more extreme weather. 

Mayor Khan said: “In London we are taking bold action to ensure that we halt the decline of biodiversity in our natural environment. Since being elected, I have invested almost £30 million in green space and tree planting projects, and City Hall’s world-leading Rewild London Fund is helping to restore the capital’s precious wildlife sites, improve biodiversity and ensure all Londoners have a thriving web of nature on their doorstep.
