CO2 regs are not about pollution but about forcing people to buy energy efficient appliances.
It has always been my opinion that they took lead out of gasoline in order to destroy the valves in all of the old cars and force everyone to buy new cars. It supported the auto manufacturers and more importantly it supported the banking industry with all of the loans. And it put everyone in perpetual debt.
