No ZEV law here...the only part of the CARB guidelines that we did not adopt in 2005, because of auto dealer opposition. I don't think (though I am not sure) WA was even asked to participate.
Gov. Inslee just had a workshop a couple of days ago, and there is a possibility that WA will become a ZEV state. I have mixed feelings about it...I don't think we would be where we are without ZEV laws, but I suspect there may be better ways forward. I am not a big fan of supply-side mandates. Although I have to admit if a lot of states get on the ZEV bandwagon, the compliance automakers are going to find it in their own best interests to build compelling EVs.
