The Group of 20 (G-20) lands this week not only on U.S. soil, but on the old stomping grounds of yours truly. President Barack Obama, in a fairly surprising move, chose Pittsburgh as the meeting place for the world's 20 most powerful leaders (representing 85% of the global economy).

Why? Well, aside from his ties to the Rooney family and choosing the Steelers (accurately) to win Superbowl XLIII, the President feels Pittsburgh is "an area that has seen its share of economic woes in the past, but because of foresight and investment is now renewed, giving birth to renewed industries that are creating the jobs of the future," according to White House Spokesperson Robert Gibbs.

These "renewed industries" and "jobs of the future" refer to, in part, Pittsburgh's replacement of an environmentally unsound and unsustainable industry base (mining, steel mills) with a multitude of "greener" jobs. Obama would like to present this "bold move" by the city as a sort of micro-example for the world, that shutting down plants for non-renewable resources does not have to mean a down economy and thousands of lost jobs. In fact, the average "green collar" job earns 10% to 20% more than it's blue collar iteration.

But is all of the G-20 on board with Barack? You might be surprised to see who does have a green agenda...and who doesn't (I'm looking at you, Canada).
