This doesn't make any sense for three main reasons. First, we are in a climate emergency and we should be looking at ways to reduce greenhouse gases, not increase them. Second, greenhouse gases are not the only pollutant released. The roll back will increase air pollution throughout the state (and the rest of the U.S.) leading to more health problems. Third, car manufacturers don't want to roll back the emissions standards. Many Fortune 500 companies now recognize the special responsibilities they have to the environment and are trying to find ways to improve the environment and enhance sustainability.
I am certain that this will end up in court and waste lots of smart people's time. In the mean time, if the polls are correct, there will be a new president in 2020 who will drop this foolish endeavor.
