SustainLane, an online people-powered guide to sustainable living has named Portland, Oregon the most sustainable city in their annual
US City Sustainability Rankings.
The rankings were developed using a combination of primary and secondary research and are determined by averaging 16 individual category rankings, including air quality, city commuting, green economy, metro street congestion and planning/land use.
The top ten cities to make the SustainLane sustainability city list:
- Portland, Oregon
- San Francisco, California
- Seattle, Washington
- Chicago, Illinois
- New York, New York
- Boston, Massachusetts
- Minneapolis, Minnesota
- Philadelphia, Pennsylvania
- Oakland, California
- Baltimore, Maryland
Compare this to a similar list published by
Popular Science earlier this year which lists America's 50 greenest cities. Surprise! Porland, Oregon anchors the top of the list with only a couple diversions -- Eugene, Oregon and Austin, Texas. Their methodology used raw data from the U.S. Census Bureau (gotta love that
factfinder) and the
National Geographic Society’s Green Guide, which collected survey data and government statistics for American cities of over 100,000 people in more than 30 categories, including air quality, electricity use and transportation habits. They compiled the statistics into four broad categories - electricity, transport, green living and recycling and green perspective - each scored out of either 5 or 10 possible points. The sum of these four scores determined a city’s place in the rankings. Simple!!?
