Kaid Benfield presents the evidence that compact development can bring about a decrease in noxious emissions.
Benfield quotes a study in the Seattle area that indicates that:
"...each 25 percent increase in walkability is associated with a 5.6 percent reduction in NOx emissions and a 5.5 percent reduction in emissions of VOCs, due to reduction in vehicle trips These conclusions are consistent with those reached by Reid Ewing and Robert Cervero in their exhaustive "meta-analysis" of literature on travel and the built environment."
Benfield also cites a 2007 report from the EPA, which concluded that "strong support for infill development can be one of the most effective transportation and emission reduction investments regions can pursue."
