While many environmentalists have been upset by the Bush Administration’s refusal to sign onto the Kyoto global warming treaty, they may be happy to learn that U.S. efforts to curb greenhouse gases are faring far better than they expected. Indeed, the United States has only seen its carbon dioxide emissions rise a very modest 1.7 percent between 2000-2004, which is considerably below those of European nations which signed onto Kyoto yet saw their emissions grow at a hefty 5 percent over that same period. When you also consider that the America leads the world in offering developing nations improved technologies to curb their greenhouse gases, it seems Uncle Sam’s actions are speaking louder than his words.
