""Cities are more location-efficient, meaning key destinations are closer to where people live and work," said CNT President Scott Bernstein. "They require less time, money, fuel and greenhouse gas emissions for residents to meet their everyday travel needs. People can walk, bike, car-share, take public transit."
Looking at particular Chicago neighborhoods, the study found that Pilsen, the Irving Park/Sheridan area and South Shore had some of the lowest household emission counts -- 3 or less metric tons of carbon dioxide per household per year. Beverly scored on the high side for city neighborhoods, at 7.2 tons."
