"WASHINGTON — In November 2010, three combatants gathered in a sleek office here to build a carbon emissions policy that they hoped to sell to the Obama administration.
One was a lawyer who had been wielding the Clean Air Act since his days at the University of California, Berkeley. Another had turned to practicing environmental law and writing federal regulations to curb pollution after spending a summer on a pristine island off Nova Scotia. The third, a climate scientist who is a fixture on Capitol Hill, became an environmentalist because of postcollege backpacking trips in the Rockies.
The three were as seasoned and well connected as Washington’s best-paid lobbyists because of their decades of experience and the relationships they formed in the capital."
