The Kyoto Protocol can only serve as the first step in addressing the risks posed by global climate change. The next step in international climate change policy drew substantial attention in 2007. At the Group of Eight industrialized countries meeting in Germany, which was joined by five major developing countries, world leaders called for moving forward through the UN process with the successor to Kyoto. Secretary-General Ban Ki-moon hosted a special high-level session on climate change policy in the UN General Assembly in September and has called for negotiations on this next step to culminate with an agreement by 2009. U.S. President George W. Bush hosted a meeting of 16 major countries from the developed and developing world to address this question in September as well.
