Powering Personal Choice for Global Impact

PEIR, the Personal Environmental Impact Report, is a new kind of online tool that allows you to use your mobile phone to explore and share how you impact the environment and how the environment impacts you.

What's unique about PEIR? Taking a step beyond a "footprint calculator" that relies only on your demographics, PEIR uses location data that is regularly and securely uploaded from your mobile phone to create a dynamic and personalized report about your environmental impact and exposure.

How PEIR Works

PEIR gives you greater control over your environmental impact and exposure by allowing you to interactively explore how it creates its results from your activity patterns.
