While we love the bustle of city life, sometimes you need tranquil spots like parks, gardens and other natural spaces to retreat to. Offering somewhere to take a stroll, have a picnic or even just sit and watch the world go by, these landscapes play a big part in the city life. Equally, having enough trees in an urban area is integral for improving air quality, which has huge benefits for human health. Using data from the European Environment Agency, we reveal the European capitals with the highest percentage of green infrastructure (including parks, trees and other natural features).
