In the Fall 2007 semester, David Warners and I challenged our students with the question "What would it take to make Calvin carbon neutral?" We called it the Calvin College Carbon Neutrality (CCCN) project. We wrote a paper forPerspectivesthat summarizes the experience.

This page collects several details of the project in hopes that others will find it useful. These documents are referenced in our Perspectives paper.
