Methodology & Disclaimer
The State Climate Policy Dashboard tracks only passed policy, not policy under consideration. It is not intended to evaluate the quality of state policy or rank states. For the purpose of this map, some policies are weighted corresponding to their importance. The map data provided on this page is purely illustrative. Nothing on this page constitutes legal advice.
All information contained in this database is derived from information in the public domain. All information is collected by Climate XChange and subsequently reviewed by partner organizations and members of the State Climate Policy Network.
This is version 1.5 of the State Climate Policy Dashboard.
