In short, he argues–quite convincingly–New York is a model of sustainable development because New Yorkers…

Live Smaller

• High population density also necessitates smaller living spaces, which consume less electricity than larger houses in non-urban areas.

• Tall, multi-story buildings that share walls with adjacent structures save heat. Less wall and rood area is exposed to the sun, which reduces summer air-conditioning loads.
• High population density means that city dwellers live in closer proximity to each other and to other destinations, which makes it less likely that residents will choose a car as a means of transportation.

• Traffic congestion in highly dense, geographically compact cities provides a further enticement for residents to use public transportation instead of opting for a car or a taxi.
• The extensive cultural and social establishments of cities—including museums, movie theaters, and other artistic organizations—allow for urban residents to enjoy entertainment without driving long distances.
• Extensive public transportation provides for a lighter carbon footprint than that of an area where most people drive cars.
