The United States Climate Alliance is an effort by state governments to support the Paris Climate Accord and help reduce emissions in the United States. There is however a constitutional problem with this organiazation as it may qualify as an interstate compact which is expressly forbidden by the US constituion without consent from congress.
No State shall, without the Consent of Congress, lay any Duty of Tonnage, keep Troops, or Ships of War in time of Peace, enter into any Agreement or Compact with another State, or with a foreign Power, or engage in War, unless actually invaded, or in such imminent Danger as will not admit of delay.
(US constition Article 1 clause 3)
This leads to an interesting situation. Congressional Republicans aren't generally in favor of big actions to fight climate change, but they are generally in favor of empowering local and state government; what they view as proper federalism. From the GOP platform:
We pledge to restore the proper balance and vertical separation of powers between the federal government and state governments — the governments closest to, and most reflective of, the American people. We encourage states to reinvigorate their traditional role as the laboratories of democracy, propelling the nation forward through local and state innovation.
Have congressional Republicans taken a position (or taken action) on whether they will give "consent" to the United States Climate Alliance as an interstate compact?
