To eliminate the impact of regional and technological levels in the energy conversion process we improved the IPAT model and used it to predict and analyze China’s per capita carbon emissions in three assumed scenarios up to 2050. We found that China’s per capita carbon emissions peak wil occur respectively in 2020 and 2030 in different assumed scenarios; national per capita carbon emissions wil reach 2.0127–2.6791 tons; China’s per capita carbon emissions wil grow continuously at an average rate of 2.25%–3.40% per year before the peak year and then wil decline at a rate of 1.33%–1.78% per year. By the year of 2050, national per capita carbon emissions wil be 1.3147–1.8817 tons.展开更多
