Failures of environmental law to preserve, protect and improve the environment are caused by law’s contingency and constitutional presumptions of supremacy over the self-regulatory agency of nature. Contingency problems are intrinsic to law and, therefore, invite deployment of technologies. Constitutional presumptions can be corrected through geo-constitutional reform. The latter requires the elaboration of geo-constitutional principles bestowing authority on nature’s self-regulatory agency. It is suggested that principles of autonomy, loyalty, pre-emption, supremacy and rights have potential to serve that aim and imply proactive roles for technologies in environmental governance. Geo-constitutional reform is necessary to prevent the fatal collapse of the natural regulatory infrastructure enabling life and a future of environmental governance by design. Once environmental catastrophe has materialized, however, geo-constitutionalism loses its raison d’être.
