The goal is to get more states to join this: https://en.wikipedia.org/wiki/United_States_Climate_Alliance - which essentially looks at ensuring states are "committed to upholding the 2015 Paris Agreement on climate change within their borders, by achieving the U.S. goal of reducing emissions 26–28 percent from 2005 levels by 2025". It's not the same as the US being part of the Paris agreement, but it's the next big thing at the moment looking at lowering emission levels throughout the US.
