The Pathways toward Carbon Peak and Carbon Neutrality in China’s Building Sector

Achieving carbon peaking and carbon neutrality in the building sector is an important component of China’s “dual carbon” goals. In recent years, the country’s direct carbon emissions in the building sector have hit a plateau while the total emissions still grow rapidly. Besides, the building materials for construction and refrigerants leaked during buildings’ operation also result in greenhouse gas emissions. To achieve the targets set for future low-carbon development, the building sector should feature “sufficient demand, decarbonized structure and flexible load.” According to the analysis of the emission reduction approaches adopted by different sectors, China’s building sector should make a ceaseless effort to promote building energy conservation, improve electrification, and load flexibility, reform the energy system in rural areas, optimize the heating structure in northern China’s urban areas, as well as reduce the emissions during construction and the non-CO2 gas emissions. In the 14th Five-Year period, it is suggested to clarify the total energy consumption and carbon emission targets, adjust the energy structure more vigorously, and draw up more measures to reduce the emissions related to construction and refrigerant leakage.
