I don't recall a fed mandate on climate.. Its just a power grab. Fed should stay out of climate change until mandated by congress. It seems like just a way to give government and the fed more power and the people less power. For example, If government mandated everybody buy an electric car or stop driving, Most Americans can't afford a new electric car, or a used electric car and a $10,000 battery replacement. So the poor will suffer and the rich will have less traffic. We have to let the free market work.
