Scientists confirm sprawl is major cause of greenhouse emissions

摘要

Urban sprawl is a major generator of greenhouse emissions, America's National Academies of Science has concluded, and compact, mixed-use development can significantly reduce it.rnThe report by the Academies' Transportation Research Board says that the number of miles Americans drive each day has tripled since 1980 and many policies still favour growth of low-density, dispersed sprawl. Transportation now accounts for almost a third of greenhouse emissions.
