- China promised to achieve CO2 emissions peak by around 2030. Beijing, as a pilot low carbon cities, has announced to reach carbon emissions peak by around 2020. It is expected to play a leading role and to enter into a post-fossil carbon society earlier than others. The analysis revealed that Beijing should control its future emissions by primarily controlling total energy consumption and expanding the scale of imported green electricity. The energy intensity reduction targets are predicted to be 17% and 20% during the 14th Five-Year Plan period. Decomposing targets to districts has been approved to be one of the most effective ways. However, most of relative studies adopt a state-to-provincial level of analysis and few could balance theoretical analysis and practical allocation. Considering equity, operability and feasibility, reduction pathway method, type assignment method, and average adjustment method are applied for Beijing. The methods have obvious effects on energy consumption in Shunyi, Chaoyang, Fengtai, and Haidian, which energy consumption is almost half of Beijing’s total. The differences in carbon emissions for districts are less than 4% of the highest in 2025, while decomposition targets differ 0 to 3 percentage points. If Beijing is required to peak around 2020, then Tongzhou, Shunyi, and Daxing would peak later than 2025. However, if Beijing should peak earlier, then all districts except Shunyi should peak earlier than 2020 or even earlier than 2015. This assessment framework could be applied in other regions or countries to help local governments to make a more reasonable and compromising carbon mitigation plan.
