Levin: Climate bill must take go-slow approach with factories, block state tailpipe rules


Levin also argues for a national standard for emissions from cars and trucks that would prevent states from adopting different rules.

California – and about a dozen other states that follow its lead on emissions rules – are deferring to an upcoming national auto emissions and mileage standard that covers model years 2012-2016.

But Levin wants a long-term national emissions standard that preempts state efforts in order to avoid a patchwork of requirements for the industry.

Levin’s other goals include a "realistic and firm" price collar, or set of boundaries on the price of carbon emissions, which he said is needed to prevent excessive costs and ensure “certainty” for business investments.
