Last week, Grist released a list of 15 green cities, and San Francisco came in at number eight, just behind London. Up against cities like Reykjavik, Iceland (number one on the list), Portland, Oregon (number two), Malmo, Sweden (number four), and Vancouver, Canada (number five), the city by the bay isn't so shabby when it comes to living the green life. According to Grist, half of all San Franciscans use public transportation, bike, or walk every day. Another notable greenlight is that parks and green space comprise 17 percent of the city. Grist also thinks San Francisco is ahead of the game for banning non-recyclable plastic bags and funding renewable energy to power public facilities.
