Congress failed last year to pass limits and let companies buy and sell pollution permits. That system was known as "cap and trade" — but to Republicans it was "cap and tax" because they said it would raise energy prices.
The administration now say it'll act on its own to clamp down on power plant and oil refinery greenhouse emissions by developing new standards over the next year.
But Michigan Rep. Fred Upton tells "Fox News Sunday" that the GOP-led House won't "let this administration regulate what they've been unable to legislate." He says Republicans want to tackle the problem "in a reasonable way."
