5 Green Cities of the Future

Single-car drivers commuting in fossil-fuel burning cars, smog­, pollution, crime — what other ur­ban scourges can you think of? Half of the world’s populationcurrently live­s in urban areas; yet these urban areas make up only 2 percent of the world’s land and spend three-quarters of the world’s resources [source: MIT]. That’s a lot of people in a very small space consuming a great deal.

Between now and the year 2050, urban growth will only continue to rise: 89 million homes and 190 billion square feet (about 17.5 billion square meters) of retail and other nonresidential space will be built in the United States alone [source: National Resources Defense Council]. And in conjunction with that density, pollution is soaring. London, for instance, released about 45 million tons (about 41 million metric tons) of carbon dioxide, a greenhouse gas, into the atmosphere last year [source: IEEE]. By greening cities and neighborhoods around the world, we have the opportunity to make a positive impac­t on global warming.

How do green cities help in the effort against climate change? Eco-cities all share similar characteristics: They aim to reduce or eliminate fossil-fuel use, adopt sustainable building practices, promote “green space” and clean air quality, implement energy-efficient and widely available public transportation, create walkable city designs and develop well-organized mixed-use neighborhoods that combine living, working and shopping. These qualities add up to sustainable urbanism.

Here we’ll look at five green cities of the future — some that have broken ground for construction, some that are still the ambitious aspirations of city planners — all competing to be the first carbon-neutral city in the world.
