The legendary Argo is said to have a crew of 50 men, before their adventures took their toll. The Zeronaut 50 Roll of Honor is a first listing of some of the leading innovators who are pushing towards (or in a few cases beyond) zero in such areas as carbon, waste, toxics, population growth, poverty and pandemics.

Once the book is published, we will begin to post both the full Roll of Honor and a series of perspectives by leading Zeronauts.
