Legal experts doubt a new executive order will block state action on climate change. But likely court battles could be costly for states.

The Trump administration and Department of Justice lack legal grounds to overturn most state climate laws, legal experts said Wednesday following a presidential executive order targeting such mandates.

Trump‘s executive order late Tuesday also asks Attorney General Pam Bondi to block “illegal” state lawsuits against the oil industry that seek to recoup damages for climate impacts.
