“…The environmental impacts of embodied carbon outflows in Anhui have exceeded expectations, with the main carbon reduction stress stemming from the high share of carbon emissions from energy-intensive industries (e.g., the cement and steel industries, which account for 38 per cent of the province's carbon emissions from fossil energy consumption, which is 13 percentage points above the national average [68]) and the lack of a total amount of low-carbon alternative energy sources. According to several projections [69][70][71], Anhui Province will not be among the first team to reach the peak. Inner Mongolia has consistently been a key net embodied carbon outflow province between 2007 and 2017, which is closely related to its positioning as an energy production base and its industrial structure.…”

Embodied carbon flows among regions have led to unfair carbon emission responsibility accounting based on production. However, the heterogeneity of carbon peaking stress between regions is significantly neglected for those embodied carbon flows. Incorporating the carbon peaking stress into the embodied carbon flows can more clearly show what causes the carbon peaking stress and which carbon flow paths are more critical. In this study, the decoupling index of carbon emissions and economy development was applied to characterize the carbon peaking stress in each region, and the environmental extended multi-regional input–output model was applied to re-evaluate the criticality of regional embodied carbon flows. The results showed that the carbon peaking stress in China improved from 2007 to 2012, but the rebound of carbon peaking stress in 2017 made most regions reverse the previous downward trend. The stress to reach carbon peaks varies considerably from region to region, and the stress in the northwest is much higher than that in developed eastern China. Considering the heterogeneity of carbon peaking stress, additional concerns should be given to the net embodied carbon output in the northwestern, northern, and central regions, which can help avoid the dilemma between outsourcing embodied carbon and reducing carbon emissions from production. The policy to reduce emissions should be implemented in all regions that benefit from the net embodied carbon output of the northern and northwestern regions, where the carbon peaking stress is higher. The focus should be on the actual improvement of the carbon peaking stress, not just on the transfer of stress. The increasing urgency of achieving carbon peaking targets and unequal stress for regional peaking emissions calls for differentiated regional mitigation measures to help the Chinese government scientifically and in an orderly manner promote the overall and local carbon peaking work.

“…The Chinese government set a "30-60" emissions target for carbon peaking and carbon neutrality in 2020, and the Ministry of Housing and Urban-Rural Development (MOHURD) issued the Implementation Plan for Peak Carbon in Urban and Rural Construction in 2022. With the continuous improvement of the national and provincial plans for carbon peak implementation for the building sector 7,8 , the work to achieve a carbon peak in buildings will gradually be implemented at the city level, but the serious lack of data on carbon emissions in buildings at the city level is a constraint to the implementation of this work.…”

AbstractsThe building sector, which accounts for over 20% of China’s total energy-related carbon emissions, has great potential to reduce emissions and is critical to achieving China’s emissions peak and carbon neutrality targets. However, the lack of data on operational carbon emissions and end-use carbon emissions in the building sector at the city level has become a major barrier to the development of building energy conservation policies and carbon peaking action plans. This study uses a combination of “top-down” and “bottom-up” methods to account for the operational carbon emissions of buildings in 321 cities in China from 2015 to 2020. The energy consumption in buildings is further broken down into six end uses: central heating, distributed heating, cooking and water heating (C&W), lighting, cooling, appliances and others (A&O). The dataset can serve as a reference to support city-level policies on peak building emissions and is of great value for the improvement of the carbon emissions statistical accounting system.

“…The Chinese government has established several low-carbon strategies to regulate and solve high carbon emissions by actively supporting the "energy saving and carbon reduction" program and encouraging the development of low-carbon cities and economies [2]. However, problems such as carbon inefficiency and high building energy consumption in construction remain a concern [3], and as China's urbanization progresses, its construction industry's share of energy consumption and carbon emissions will continue to increase [4]. The construction industry already represents one of the largest carbon emitters in China [5], is characterized by extensive resource consumption and long operation times, and has become a potential impediment to China achieving its dual-carbon goals [6].…”

Since decoration is an essential part of buildings, the carbon emissions generated by decoration work should not be ignored. In recent years, prefabricated decoration has attracted much attention as efforts are made to pursue green, low-carbon, and waste-reducing buildings. However, research on carbon emissions assessment of prefabricated buildings has focused mainly on the structural aspect of prefabricated buildings, with few studies having considered prefabricated decoration. This study therefore focuses on assessing the carbon emissions of prefabricated decoration from the life cycle perspective of a case study residential building and explores the potential for reducing carbon emissions by decorating buildings with prefabricated components. The results show that using prefabricated decoration in the case study building reduced carbon emissions by 29.08% at the building material production stage compared to traditional decoration, and using an optimized design of prefabricated decoration, the building’s energy consumption over its design life could reduce carbon emissions by 1046 kgCO2/m2. These findings demonstrate the benefits of prefabrication decoration for reducing carbon emissions. This study provides decoration companies with robust data and insights to guide future decisions and practices, helping to transform and achieve the carbon neutrality goal for the building decoration industry.
