The useless Kyoto Protocol's emphasis is on CO2 emissions. The exclusion of India and China was a political decision because the Kyoto Protocol ostensibly addressed current greenhouse gas producers, and India and China weren't considered major at the time, though there potential growth in emissions was obvious. The significance of black soot aerosols to global warming has only recently been recognized. Because black soot emissions are also hazardous to health (particularly large particle emissions from fires and industrial pollution), the idea of getting China and India to cooperate more on global warming issues by controlling black soot has been offered on the dual basis of climate and health benefits.
So essentially it was a political/economic decision rather than being based on environmental issues?
Therefore President Bush's decision to disregard this issue is not an environmental decision.
