In this Thursday, Sept. 20, 2012 photo, air conditioning of the Qatar National Convention Center (QNCC) in Doha, Qatar. Green buildings would seem an oddity in this tiny Gulf nation which has plenty of oil and gas and, according to the International Energy Agency, the highest per capita emissions in the world, closely followed by Gulf neighbors Kuwait, Bahrain and the United Arab Emirates. But attitudes about energy use are changing across the Gulf. There is a growing recognition that the once seemingly limitless fossil fuels will someday run out and that these countries need to chart a more sustainable path. (AP Photo/Osama Faisal)
