Megacity metabolism: is your city consuming a balanced resource diet?

UofT Civil Engineering magazine June 2015

New York is an energy hog, London and Paris use relatively fewer resources and Tokyo conserves water like a pro. These are just a few of the findings from a new study on “megacity metabolism”—the world’s first comprehensive survey of resources used and removed in each of the planet’s 27 largest metropolitan areas. Led by engineers at the University of Toronto, an international team of researchers examined data on how resources pass through the globe’s largest cities, such as burning natural gas for heating, using electricity for public transit or disposing of solid waste and wastewater.
