Portland is well-known for its musical culture and other alternative movements. While you will find everything from punk rockers to naked bike riders, one of the things everybody agrees on is the importance of taking care of the environment. Popular Science calls Portland the greenest city in America, coming in ahead of San Francisco and Boston. The city’s energy source is 50 renewable, and about of commuters take a bike, carpool, or use public transportation.The DIY culture is also an important aspect of the city’s high rank. Rather than buying from large, wasteful chain stores, Portland offers residents and visitors alike many venues for taking things into their own hands. For example, Bolt Fabric Boutique sponsors classes from Beginning Patternmaking to Adult Zippered Hoodies. Small publishers are also supported by zine distributors like Microcosm, which publishes everything from political commentary to music reviews in order to make people care more about the world around them.Tourists with an eye for the environment will also be interested in Portland’s sewer system, which cuts water pollution using elements like gutters and planted barriers to absorb rainwater. The Portland website offers a map of the most interesting locations for green visitors looking to get their feet wet. Homeowners in the city are helping out by disconnecting their downspouts from the storm-water system and instead using rain gardens and barrels.Portland Walking Tours are the most eco-friendly way to travel the city, and you can catch a guided one every Friday, Saturday, and Sunday. USA Today calls it one of the top 5 walking tours in the nation, and includes locations like the world’s smallest park, which was built as a leprechaun colony in 1948. Talk about staying green!
