I just sent my renewal in for the Red stickers to replace the Green ones. If you purchased the vehicle after Jan '18, you are eligible for the Red ones that will last until 2022.
Since I purchased in February, I was lucky enough to get the Red stickers.
Who knows what changes will happen in the future? Sooner or later, there will be more alternate fuel vehicles than ICE ones. Probably a long ways off.
BTW, saw the video for the new Camaro Electric vehicle. Looks like a winner.
