Yesterday [Oct 3 ed.], Democratic Sens. Kerry and Boxer dropped their initial version of a Senate climate bill, so the game’s on. We’ll defer to Brad Plumer’s Vine post for a good side-by-side comparison, but suffice it to say the Kerry-Boxer Senate outline looks a lot like the Waxman-Markey bill that passed the House earlier this year, with a few differences.
Like the Waxman-Markey legislation, the Senate version sets emissions targets (a little stricter than the House standard with a 20 percent emissions reduction from 2005 levels required by 2020 and 83 percent by 2050). Like Waxman-Markey, Kerry-Boxer proposes a pricing and emissions trading mechanism (now called, euphemistically, a Pollution Reduction and Investment tool, with revenue allowances left undetermined).
