Comparison of Energy-Related CO2 Emissions Between China and the US

Under the pressure of rise in global temperatures, carbon dioxide emission has become one of the themes the world most focus on. This paper compares the energy-related CO2 emissions between China and the U.S. by the new method of CO2 emissions per unit square land. The results showed that the energy related CO2 emissions in China and the U.S. had comparatively large negative external influences to the world. For the reason that the two countries should launched into wider international technical cooperation with other countries to reduce carbon emissions and protect human environment on the basis of improve energy efficiency and energy structure.
