The Global Status Report for Buildings and Construction is a reference document of the Global Alliance for Buildings and Construction (GlobalABC). The fifth edition of this annual snapshot of the progress of the buildings and construction sector globally towards the achievement of the goals of the Paris Agreement on Climate Change, particularly on the drivers of CO2 emissions and energy demand globally and the status of policies, finance, technologies, and solutions that support a zero-emission, efficient, and resilient buildings and construction sector. This year’s Buildings-GSR features input from over 110 GlobalABC members and experts from all regions: a true collaborative effort, building a global community. 

This year’s Buildings-GSR shines a light on the disruptions of COVID-19 and some of the responses in 2020, and includes a snapshot on emerging key issues: materials, nature-based solutions, health, and cooling for resilience. It also introduces a new index to track progress in decarbonisation in the sector – the Buildings Climate Tracker (BCT).

While the total final energy consumption of the global buildings sector remained at the same level in 2019 compared to the previous year, CO2 emissions from the operation of buildings have increased to their highest level yet at around 10 GtCO2, or 28% of total global energy-related CO2 emissions. With the inclusion of emissions from the buildings construction industry, this share increases to 38% of total global energy-related CO2 emissions. The slightly lower proportion of buildings emissions compared with the 39% seen in 2018 was due to the increases in transport and other industry emissions relative to buildings.

《2020年联合国全球建筑状况报告》重点介绍了新冠病毒-19的破坏情况以及2020年的一些应对措施，并简要介绍了新出现的关键问题：材料、基于自然的解决方案、健康以增强恢复力。它还引入了一个新的指数来跟踪该行业的脱碳进展——建筑气候跟踪器（BCT）。尽管2019年全球建筑行业的最终能源消耗总量与前一年保持相同水平，建筑物运行产生的二氧化碳排放量已增至目前的最高水平，约为10 Gt CO2，占全球能源相关二氧化碳排放总量的28%。随着建筑业排放量的增加，这一比例增加到全球能源相关二氧化碳排放总量的38%。与2018年的39%相比，建筑排放比例略低，这是由于交通和其他行业排放量相对于建筑的增加。
