President Bush believed that unless the Kyoto mechanism was applied to developing countries, especially China and India, which would see large increases in energy demand in the future, even US achievement of emission reduction targets would not be enough to counter the growth in global greenhouse gas emissions.
布希總統認為，未來能源需求會大幅增加的是開發中國家，尤其是中國與印度，「京都機制」若不管制他們，就算美國達成減量目標，也無法抑制全球溫室氣體成長的趨勢。
