GM gets it.

Last week in San Francisco General Motors signed the "Climate Declaration".  The first automaker to do so, there are about 30 large companies signed up so far.  The declaration calls on policymakers to move quickly on climate change by promoting clean energy, efficiency, and limiting carbon emissions.  GM executives say they have reduced waste in all operations, energy use, and added solar panels to many of their roofs, and much more is to come.  It's making them more competitive.  Everything going to the land fill was money down the drain.
