The 7 cities with the most green space around the world

There's a global movement toward growing more trees and planning more parks in cities. But which ones have the most green space today?

To get a clearer picture, MIT partnered with the World Economic Forum (WEF) to create Treepedia, a site with interactive maps that show the density of greenery in 10 major cities around the world. The researchers used information from Google Street View to make what they call the "Green View Index," a rating that quantifies how many trees are on every street.

The ultimate goal of Treepedia is to make make urban planning more accessible to those outside the field, MIT's Carlo Ratti said in a press release.
