The way communities plan neighborhoods has profound effects on the natural environment and public health. A new study released by the Environmental Protection Agency’s (EPA) Smart Growth Program finds a link between environmental quality and land use and transportation strategies.

The second edition of Our Built and Natural Environments: A Technical Review of the Interactions Among Land Use, Transportation, and Environmental Quality, an update to a 2001 report of the same title, details how development can impact human and environmental health. “As the U.S. population has grown, we have developed land that serves important ecological functions at a significant cost to the environment,” the report states, going on to say, “Changing where and how we build our communities can help mitigate these impacts, improving how development affects the environment and human health.”
The report identifies hows our development patterns have negatively affected the natural environment, the report finds, “Transportation is responsible for 27 percent of U.S. greenhouse gas emissions; residential and commercial buildings contribute 18 percent and 17 percent, respectively.”
As solutions to these mounting problems, the report demonstrates the benefits of specific development strategies. The report recommends preserving ecologically valuable sites and placing a stronger emphasis on infill develop and transit oriented development. Each of these strategies reduce the number of vehicle miles traveled and, in turn, greenhouse gas emissions. The report also emphasizes the need for community design that addresses development’s potential downsides, offering investing in mixed-use development and improving street connectivity as solutions.
“Whether it’s housing, transportation, or environmental issues, this report can help communities protect public health and the environment by avoiding harmful development strategies,” said Acting EPA Administrator Bob Perciasepe.
The EPA’s Smart Growth Program is part of the Partnership for Sustainable Communities, a collaboration between the EPA, the Department of Housing and Urban Development and the Department of Transportation. The Partnership has allocated more than $4 billion for communities across the United States, improving local economies and environments. The Partnership works with communities to create more housing and transportation choices, and support neighborhoods’ sustained vibrancy by attracting new business.
