In December 2007, Charles Perilloux, an American chemical engineer, traveled to China to help install inexpensive and game-changing technology at a Chinese chemical plant that was spewing a climate "super-pollutant" into the atmosphere. The emissions quickly fell to near zero. The state-owned Henan Shenma Nylon Chemical Company manufactures adipic acid, a key ingredient in nylon and polyurethane, which is used in everything from car parts to running shoes. While producing adipic acid, the factory emitted thousands of tons of nitrous oxide, a greenhouse gas nearly 300 times more potent than carbon dioxide in warming the planet.
