The Sabin Center for Climate Change Law has launched a new database to track environmental actions undertaken by state attorneys general. The center partnered with, a research and education website, to build the database, which includes legal actions initiated by state attorneys general against the federal government, private actors and other public entities; defensive actions taken in support of federal and state rules; amicus briefs; regulatory petitions and other forms of participation in administrative proceedings; legislative inputs (e.g., congressional testimony and bill proposals); and other types of interventions. is a legal research and education website that examines and communicates the role and impact of state attorneys general in law and national policy.

The new state-level database includes some of the major and innovative actions aimed at advancing the ball on environmental law and policy. It does not encompass all of the routine enforcement actions undertaken by state attorneys general. The site allows readers to filter actions by topic, type or jurisdiction or browse and search a table of all actions being taken.

The new tool follows on the heels of a federal “Climate Deregulation Tracker” which launched in January (see Tracking the Undoing of Climate-Change Measures). That tool identifies and explains the efforts taken by the Trump administration to scale back or wholly eliminate federal climate change mitigation and adaptation measures. That database also tracks congressional efforts to repeal statutory provisions, regulations and guidance pertaining to climate change, and to otherwise undermine climate action.
