A Quick Measurement Method of Urban Low-Carbon Development: Energy Allocation Analysis, TRO Index, and Case Study of Beijing Zhenyu Shi, Weiqi Li, Yuning Fu, Linwei Ma, Zheng Li

Abstract

Urban low-carbon development is a dynamic process requiring a systematic method to observe its progress continuously and quickly. The Energy Allocation Analysis (EAA) and TRO index established at national level can meet this requirement. The paper aims to develop an EAA-TRO method suitable for quickly analyzing urban low-carbon development and validate it by a case study of Beijing. Firstly, an EAA method is established for accounting the responsibilities of energy consumption and carbon emissions in the whole energy system. Secondly, TRO index is established to identify driving forces. The results of the case study indicate that Beijing’ s energy consumption rises from 69.9 Mtce (2017) to 71.2 Mtce (2021), with carbon emissions increasing from 146.6 to 154.8 Mt CO2. The energy supply shifts from coal to electricity and gas which totally account for 70.3% of emission responsibilities in 2021 and are mainly purchased from outside. Meanwhile, the energy consumption becomes more concentrated in buildings which accounts for 57.8% of emission responsibilities. Therefore, more attention must be paid to control building energy consumption and improve energy conversion efficiency while promoting electrification and coal reduction.
