Long subordinate to global economic governance, global environmental governance currently fails to produce responses that match the urgency and depth of global environmental challenges, as well as being short on justice and democracy. Environmental political theory can speak to this condition though the critique of the deficiencies of governance, scrutiny of reform proposals, and development of dynamic criteria to seek in improved governance. At issue here are not just institutions generally recognized as environmental, but the system of global governance in its entirety. In the Anthropocene, ecosystemic reflexivity can be recognized as properly the first virtue of global environmental governance.
