From hanging clothes out to dry to using rain barrels and buying secondhand clothes, the Nalgene Least Wasteful Cities Study puts the nation’s top 25 metro areas under scrutiny for wasteful behavior. For the second straight year, San Francisco ranked the top city for responsible consumption and eco-friendly behavior. Houston ranked last. Overall, the study suggests that urban Americans have shown slight improvements in curbing their wasteful behavior.
