The world's 58 biggest cities have passed 4,700 measures to fight climate change, according to C40 Cities, a new website that launched today committed to "implementing meaningful and sustainable climate-related actions" across its network of the world's megacities. Another 1,500 action plans are under active consideration.

According to the site, 50 percent of the world's cities are already formally dealing with climate change. And 90 percent of all urban areas are coastal, putting them at increased risk for flooding. But, the site notes, cities are a major part of the problem too. Megacities produce 70 percent of the world's carbon dioxide.
