“Campoli backs this evidence up with studies that show that a holistic approach creates the most sustainable neighbourhoods: areas that combine the highest number of walkability factors have the lowest levels of driving and resulting CO2 emissions. The book's extensive use of street photography helps to illustrate why people are so happy to walk in these streets, in ways that pure statistics and analysis can never do justice.”
