The undeniable fact is that climate is global problem that requires a global solution. To be sure, industrialization in the North contributed enormously to increased greenhouse gas concentrations. Developed countries, including the United States, must take significant steps immediately.
Acting alone, however, developed countries cannot stabilize global greenhouse gas concentrations. From a scientific standpoint, meaningful participation by key developing countries is a necessity. Several large developing countries will soon become the world's leading emitters. Developing countries already produce 44% of global fossil fuel emissions.
In addition, developing countries are responsible for a disproportionate share of deforestation and other land—use practices that have raised carbon concentrations.
Per capita energy intensity ratios in some, not all, developing countries continue to rise briskly, despite the existence of clean technologies that were not invented when developed countries were industrialized. In the immediate future，80% of new electric power generation projects will occur in developing countries. All of us want those projects to use the latest cutting edge technologies.
