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 for Perspectives that 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.
