From my top stories of 2006::

California has always kicked the rest of the nation’s ass on environmental policy.

Today:

Continuing his historic leadership to reduce greenhouse gas (GHG) emissions and lower California’s reliance on foreign oil, Governor Schwarzenegger today announced he will issue an Executive Order establishing a groundbreaking Low Carbon Fuel Standard (LCFS) for transportation fuels sold in California.

From my predictions for 2007:

… [carbon] offsets will start popping up in strange venues — packaged with car insurance, in displays at gas station counters, as a checkout option in PayPal, eBay, and other online vendors, etc.

Today:

[Michael Dell] said Dell, the computer company he founded, would begin a program called "Plant a Tree for Me," asking customers to donate $2 for every notebook computer they buy and $6 for every desktop PC. The money would be given to the Conservation Fund and the Carbonfund, two nonprofit groups that promote ways to reduce or offset carbon emissions, to buy and plant trees.
