When the U.S. refused to sign up for the Kyoto Treaty on global warming, many believed America was turning its back on reducing its greenhouse gas emissions. But as noted in a recent Wall Street Journal article by former Delaware Governor Pete Dupont, Uncle Sam has in fact done better at reducing its own carbon footprint than many of its foreign critics. From 2000-2005, for instance, U.S. emissions rose only 0.6 percent, while other nations grew at 2.7 percent. Since this means we have done a better job than Canada, Greece, Ireland, New Zealand, Spain, Portugal and a number of other global neighbors, maybe a solution isn’t an international treaty, suggests Mr. Dupont, but working to improve technological innovation.
