Here’s the big news from John Kerry’s energy speech today:

I propose establishing an aggressive economy wide cap and trade program to reverse emissions growth starting in 2010. After that, we will progress to more rapid reductions and end at 65 percent below 2000 emissions by the year 2050.

That’s by far the most aggressive proposal for reducing CO2 emissions I’ve heard from any major politician.

More on the speech later.
