I co-founded and have been active in cultivating an international network of scholars who work on environmental political theory (EPT) and I facilitate an international discussion list for the group. If logged into a google account, you can join the group here. Contact me if you wish to join without a google account.
Our EPT working group hosts an annual academic workshop, scheduled in conjunction with the Western Political Science Association meeting. For it's 75th anniversary, the association published an oral history of this workshop, which has been ongoing since 2002. The WPSA also has an annual conference section devoted to environmental political theory, which has become a premier site for work in this field.
