Abstract
Taxonomies of green political theories have so far been hampered by the shortcomings inherent to their having been designed on the basis of (a selection of) popular theorists or of theories known or thought to exist. In this article, I offer a new approach: a systematic, analytical taxonomy of green ideas rather than theories. I distinguish the issues or dimensions on which green theorists can choose positions at metaphysical, ethical, political and policy levels. It is hoped that this taxonomy can both open up new avenues of green thought and help political theorists and empirical scientists in designing and evaluating their characterizations of green beliefs and ideologies.
