中国建筑节能协会成功发布2025年中国城乡建设领域碳排放报告

Core Viewpoint - The "Research Report on Carbon Emissions in China's Urban-Rural Construction Sector (2025)" was released, providing a comprehensive analysis of carbon emissions in the construction sector, supporting the goals of carbon peak and carbon neutrality, and promoting high-quality green transformation in the industry [1][3]. Group 1: Carbon Emission Data - In 2024, the total carbon emissions from the construction industry in China (including building materials and construction) reached 2.78 billion tons of CO₂, a decrease of 0.06 billion tons compared to 2023 [6]. - Among these, carbon emissions from residential buildings accounted for approximately two-thirds, totaling 1.81 billion tons of CO₂, while civil engineering emissions were 0.97 billion tons [6]. - During the operational phase, carbon emissions from civil buildings in 2024 were 2.47 billion tons of CO₂, representing 22.1% of national energy consumption [6]. Group 2: Emission Sources and Types - By building type, carbon emissions from public buildings, urban residential buildings, and rural residential buildings accounted for 43%, 39%, and 18% respectively [6]. - In terms of emission sources, electricity accounted for 66.8% of carbon emissions, while fossil energy and thermal energy each contributed 16.6% [6]. Group 3: Research and Methodology Enhancements - The report introduced new topics such as "greenhouse gas emissions from refrigerants in residential buildings" and "dynamic updates of carbon emission factors for core building materials," enhancing the carbon emission research framework [6]. - It also addressed shortcomings in the accounting of non-CO₂ greenhouse gas emissions and the lag in updating carbon emission factors [6]. Group 4: Industry Impact and Future Directions - The release of the report is expected to provide important data support for precise policy-making and efficient emission reduction in the construction sector [3][7]. - The China Building Energy Efficiency Association aims to deepen research on carbon emissions data in the construction sector and establish a technical exchange and cooperation platform to facilitate the implementation of green transformation mechanisms [7].
