What are Cities Doing to Go “Green?”

Urban areas around the world strive to lessen their environmental impact

Best described as a loose association of cities focused on sustainability, the emerging “green cities movement” encompasses thousands of urban areas around the world all striving to lessen their environmental impacts by reducing waste, expanding recycling, lowering emissions, increasing housing density while expanding open space, and encouraging the development of sustainable local businesses.

Perhaps the archetypal green city is Curitiba, Brazil. When architect and urban planner Jamie Lerner became mayor in 1972, he quickly closed six blocks of the city’s central business district to cars, delighting residents and business owners alike. Today the pedestrian-free zone is three times larger and serves as the heart of the bustling metropolis. Lerner also put in place a high-tech bus system, greatly reducing traffic, energy usage and pollution; the move also encouraged density around transit hubs and thus preserved open space in other areas that would have likely turned into suburbia. Today the bus system still goes strong, and three-quarters of the city’s 2.2 million residents rely on it every day.
