【摘要】：全球气温升高导致气候异常，引起两极冰川融化，海平面升高，严重破坏了地球生态环境的平衡，并且引发了更加频繁的自然灾害，影响着人类的生存与社会的发展。 2009年，中国政府在哥本哈根气候峰会上承诺：中国单位GDP的CO2排放到2020年，要比2005年下降40%到45%。建筑是碳排放的重要来源，作为国民经济的重要组成部分，建筑业对国民经济具有举足轻重的促进和制约作用。本文在阅读分析众多国内外相关文献资料的基础上,将国际上广泛运用的碳足迹寿命周期评价（LCA）理论与建筑工程建设过程碳排放相结合，采用基于过程的清单分析法和排放系数法，对建筑工程建设过程中的碳排放核算方法进行了研究和探讨，构建了一套适用于建筑工程建设过程中碳足迹的计算模型,并将该模型应用于实际工程中,来计算建筑工程建设过程中的碳足迹，最后得出了建筑工程建设过程中各阶段的碳足迹情况，并给出了减少建筑工程建设过程中碳排放的政策、技术与管理策略。本文通过对建筑工程建设过程中的碳足迹情况进行研究和分析，可以为建筑工程的低碳施工技术和管理改进提供参考，还可以为政府、企业及机构管理者制定建筑低碳标识及低碳环境政策与法规提供理论依据和数据支持，从而有利于节约能源，，保护环境，应对全球气候变化及实现建筑业的节能减排目标，对推进国家经济社会的可持续发展具有重要的意义。
[Abstract]:The rise of global temperature leads to abnormal climate, melting of polar glaciers and rising sea level, which seriously damages the balance of the earth's ecological environment, and causes more frequent natural disasters, which affects the survival of human beings and the development of society. In 2009, the Chinese government promised at the Copenhagen climate summit that CO2 emissions from Chinese units of GDP will be 40% to 45% lower by 2020 than in 2005. Buildings are an important source of carbon emissions and an important part of the national economy. Construction industry plays an important role in promoting and restricting the national economy. On the basis of reading and analyzing many domestic and foreign literatures, this paper combines the theory of carbon footprint life cycle evaluation (LCA), which is widely used in the world, with the carbon emission in the process of building construction. Based on the inventory analysis method and the emission coefficient method, the carbon emission accounting method in the construction process is studied and discussed, and a set of calculation model suitable for the carbon footprint in the construction process is constructed. The model is applied to the actual engineering to calculate the carbon footprint in the construction process. Finally, the carbon footprint in each stage of the construction process is obtained, and the policies to reduce the carbon emissions in the construction process are given. Technology and management strategy. Through the research and analysis of the carbon footprint in the construction process of the building engineering, this paper can provide a reference for the low carbon construction technology and management improvement of the building engineering, and also for the government. Enterprises and managers make low carbon labeling and low carbon environmental policies and regulations to provide theoretical basis and data support, which is conducive to saving energy, protecting environment, coping with global climate change and achieving energy saving and emission reduction targets of construction industry. It is of great significance to promote the sustainable development of national economy and society.
