The International Energy Agency is seeking special arrangements with China, India, and emerging countries that are slated to be the biggest carbon dioxide emitters in the next 25 years as they are estimated to account for 90% of energy growth. China already exceeds the U.S. in emissions, with India closely following the U.S., and the agency is working on enhanced communication and partnerships with those two countries as well as Brazil, Indonesia, South Africa, Russia, and Mexico.
