<ol><li> 1. source: The Wall Street Journal Buildings account for 40% of global greenhouse gas emissions. Make them more energy efficient and you help fix a mega-problem. Theres nothing else I could do . . . and have that kind of impact. Henry Paulson, former Goldman Sachs CEO, U.S. Treasury Secretary, and Nature Conservancy Board Chair, whose engagement with Xi Jinping and other China leaders spans decades, discussing his efforts to make new Chinese buildings more energy efficient.
