An American (State) in Paris – Can States Commit to the Paris Agreement?
The United States’ decision to withdraw from the Paris Agreement was a shock to environmentalists and the international community. In response, individual U.S. states took it upon themselves to pledge their commitment to the Paris Agreement without federal support. However, some scholars observed that state involvement in the Paris Agreement may be unconstitutional, a potential violation of the Supremacy Clause, Treaty Clause, and Compact Clause.
In An American (State) in Paris: The Constitutionality of U.S. States’ Commitments to the Paris Agreement, the winner of ELI’s 2017-2018 Henry L. Diamond Constitutional Environmental Law Writing Competition, Kristen McCarthy argues that states’ involvement does not violate the U.S. Constitution. Moreover, she writes, it also may set a precedent for state involvement in future environmental international agreements.
