So when White House reporters, also in New York following President Barack Obama around, got a briefing on U.N. climate change talks, the question had to be asked.

CBS’s Mark Knoller wondered about the carbon footprint of the summit: could the earnest statements on climate change be undermined by motorcades, gridlock, idling engines?

The answer: electric motorcades!

(Would that mean electric sockets on every corner in midtown Manhattan?)

“I think the U.N. should make a pledge to electric vehicle motorcades within five years,” U.S. climate negotiator Todd Stern told reporters.
