PEIR, the Personal Environmental Impact Report, is a piece of software that uses the geographical data fed into it by your GPS-enabled phone to create a report that tells you how you impact the environment (kind of like a next-generation carbon calculator), but also how the environment impacts you (your exposure to air pollution, for example).Cool concept. I like how you once you install it on your phone, it can accumulate all the data for you without requiring any additional data input. Because of the GPS in your phone, it knows where you go and can calculate all the values for you.
Right now PEIR gives you reports about 4 things: Your carbon impact, your particulate matter (PM) exposure, your fast food exposure (how many restaurants in your immediate surroundings), and sensitive sites impact (air pollution close to schools and hospitals).
