That's the conclusion of a major research project co-sponsored by the Urban Land Institute, the National Center for Smart Growth, Smart Growth America and the Center for Clean Air Policy. The just released report and book, checking in at a massive 172 pages and entitled Growing Cooler: The Evidence on Urban Development and Climate Change is a comprehensive review of dozens of studies that conclude that urban development is both a key contributor to climate change and an essential factor in combating it.
Curbing emission from cars depends on improved vehicle efficiency, cleaner fuels, and a reduction in driving according to the report. It goes on to say that one of the best way to reduce vehicle miles traveled is to build places where people can accomplish more with less driving. The report documents that persons who live in compact urban neighborhoods, where cars are not the only transportation option, drive a third fewer miles than those in the auto-oriented suburbs.
The book shares market research that shows a majority of future housing demand lies in smaller homes and lots, townhouses, and condos where jobs and activities are close by. With real estate projections showing that two thirds of development expected to be here in 2050 isn't built yet, there's still potential to get this right. And the book acts a primer on how to make green neighborhoods more available and more affordable. It also makes recommendations for shifting government regulations, spending and policies away from favoring sprawling, auto-dependant growth towards green, transit-oriented smart-growth.
"Clearly, the development industry has a key role in the search for solutions to offset the impact of climate change," said ULI Senior Resident Fellow William H. Hudnut, III, former mayor of Indianapolis. "Whether close-in or in suburbs, well-planned communities give residents the option to walk, bike or take transit to nearby shopping, retail and entertainment. Being able to spend less time behind the wheel will benefit our health, our pocketbooks and the environment."
The findings show that people who move into compact, “green neighborhoods” are making as big a contribution to fighting global warming as those who buy the most efficient hybrid vehicles, but remain in car-dependent areas.
Let's hope that developers, planners and policy makers everywhere check out this important report.
