It looks like the lawsuits proposed last year, were probably due to some overzealous lawyers.
I think California was trying to regulate greenhouse gases, including C02, but I think that has not passed as law or is held up in the court system. California smog laws are generally the toughest in the USA.

"Carbon Dioxide (CO2%): Carbon Dioxide is a colorless, odorless gas which is a byproduct of most combustion processes and also of human respiration. It is the same gas found in soda pop. High levels of CO2 in exhaust typically indicate greater engine efficiency; however, CO2 is considered a greenhouse gas that may cause global warming.
High or low levels of carbon dioxide emissions are not grounds for a vehicle failing the Smog Check; the measurement is meant as a diagnostic tool for technicians. CO2 is measured in percent. "
