A new study by a team from the University of Pennsylvania and MIT suggests it will be easier for cities to reduce CO2 emissions coming from residential energy use rather than from local transportation. This reduction will happen mostly thanks to better building practices, not greater housing density. The study is published in the Journal of Planning Education and Research.
The study used a series of fixed-ratio projections and scenarios to explore the potential for local residential energy conservation mandates and compact growth programs to reduce locally-based CO2 emissions in eleven representative US metropolitan areas. The modeling showed that averaged across all eleven metros, residential energy conservation mandates could reduce residential CO2 emissions in 2030 by an average of 30% over and above 2010 levels. . . .
