Track Your Greenness Via Phone Courtesy Urban Sensing program at UCLA

The Nokia GPS-enabled phone app, PEIR, produces a Personal Environmental Impact Report. How? It tracks you (every 30 seconds) and when you upload the data it does its best to determine if you walked or drove (how would it know you were on a bus vs. your Hummer) and where you stopped (how would it know if it was Micky D’s or the farmer’s market if they were close by and the market was only running on Wednesdays?) The idea is simply to lower your score over time. The absolute values are not that meaningful says the lead. For now the app is in closed beta but is being shown off at NextFest, a Wired event. One planned feature? A tool to compare the greenness of different routes.
