Green roofs begin to take root
High costs may hamper efforts on Mexico City roofs.

A few good reasons to get green (garden) roofs are that they can actually lower the heat in highly populated cities and then lower energy costs. Plus they suck up a lot of that pollution that's in the air, but there is a price, literally. They cost about $10 per square foot. Regular roofs are only $2 per square foot.
"The only way (green roof technology) will be effective on a citywide scale is if it's cheaper," said Mark Simmons, an ecologist at the Lady Bird Johnson Wildflower Center in Austin. Cost is the big hold up.
In Mexico City the green roof project (or the Green Plan said Mayor Marcelo Ebrard) is taking place. Their "Green Plan" is geared to tie Chicago, the "hemispheric leader" by the year 2012.
Green roofs "are like putting little air-condition units outside," said Steven Peck, president of Green Roofs for Healthy Cities, a nonprofit industry association based in Toronto. "Get enough of them, and you can actually change the climate of the city."
