Who will help President Barack Obama meet his ambitious promises to tackle climate change?

Eco-celebrities and tree-climbing protesters need not apply. This is a job for wonks.

The president’s top climate appointees and the outside advisers best positioned to shape his agenda are a team replete with heavy hitters — including green-minded business leaders, buttoned-down environmental lobbyists and bureaucrats who have spent years wrestling with the minutiae of regulations.

At the outset, the group might be light in executives from the industries that would be most affected. Some of the CEOs the administration drew support from during Obama’s first term are leaving the business or moving on to other things.
