This interactive online air pollution map lets you see what areas have the worst air quality. Biotech firm PerkinElmer created the Elm Air Monitoring Sensor Network to more accurately measure air quality in neighborhoods around the world to see where and who is being impacted most.
This sort of environmental data will help cities better manage themselves, while providing practical information that would benefit the health of its citizens. While the air pollution map is not very comprehensive, its creators are working with new communities as well as private companies to put up sensors that will gather more stats. According to their website, the small, wireless and data-focused network is about collecting, storing and sharing real-time eco information necessary for the people making sustainability-related choices for cities, and the people living there.
