“…Dong and Li conducted research on the impact of digital economy on carbon emissions [37,38]. Huo et al [39][40][41][42] studied the macro and micro driving factors of the building carbon emissions and established dynamic scenario simulation model to predict the future evolutionary trend of the building carbon emissions at different scales considering the uncertainty. Another commonly used model for studying carbon emissions is the decomposition analysis model.…”

“…Third, the huge changes in the consumption structure of residents in coastal provinces in the past decade have also had a noticeable impact on carbon emissions, and previous studies have also shown that changes in energy, industrial structure, and urban residential area are equally important to the carbon emissions of provincial cities. In combination with the research conclusions drawn by many scholars and relevant environmental characteristics of coastal provinces, seven common influencing factors are selected: total population (P), per capita GDP (G), resident consumption level (R), urbanization level (U), residential area (S), energy structure (E) and industrial structure (I) [11,[39][40][41][42][43][44][45][46][47][48].…”

With the acceleration of China’s urbanization process, the importance of energy conservation and emission reduction in the building sector has become increasingly prominent. The effective control of carbon emissions in coastal provinces has a decisive impact on achieving the carbon emissions peak target nationwide. Based on the analysis of the influencing factors, this study establishes an urban residential buildings carbon emission prediction model by combining the IPAT model and the ridge regression model. In addition, the prediction model is combined with scenario analysis to simulate the evolution of carbon emission trends of urban residential buildings in Fujian Province from 2018 to 2050 under different scenarios. The results show that total population, urban living area, residents’ consumption expenditure, urbanization rate, per capita GDP, and energy structure are key factors affecting carbon emissions from urban residential buildings in coastal cities. Only under the ultra-low carbon model scenario can Fujian’s urban residential buildings achieve the carbon peak goal in 2027 (13.4748 million tons of CO2), which requires a reduction of 59.67% compared to that under the baseline model scenario. This study can provide an effective reference for energy conservation and emission reduction work of the regional scale and even the national scale.

“…The technological revolution has reduced carbon emissions overall [46,47], and in some regions, the level of technological development may contribute to an increase in energy consumption and carbon emissions [48,49]. The expansion of urban building area and building scale will also cause an increase in energy consumption in the construction industry [50][51][52][53]. In addition, some research points out that FDI has a promoting effect on carbon emissions in various industries (except transportation) [54,55].…”

As the strategic task of China’s modernization, the implementation of new-type urbanization has an important impact on carbon emissions from the construction industry. To fill the gap in considering the spatial correlation and threshold characteristics of new-type urbanization on carbon emissions from the construction industry, this paper constructs a comprehensive evaluation indicator of new-type urbanization, and the spatial economic model and the threshold regression model are adopted to analyze the panel data of 30 provinces in China from 2002 to 2020. The results indicate that (1) carbon emissions from China’s construction industry exhibit a significant positive spatial correlation, with more than half of provinces distributed as H-H and L-L types. (2) New-type urbanization has significant positive direct and indirect effects on carbon emissions in the construction industry; the labor efficiency, energy intensity, and development level of the construction industry and trade openness also have a significant spillover effect on carbon emissions from the construction industry. (3) At this stage, new-type urbanization exhibits a threshold effect on carbon emissions from the construction industry due to the different levels of development and energy intensity of the construction industry. After crossing the threshold value, the promotion effect of new-type urbanization on carbon emissions from the construction industry gradually increases. This paper provides a reference for promoting carbon emission reduction in the construction industry in the process of new-type urbanization.

“…The carbon peak and carbon neutrality (dual-carbon) strategies necessitate the green and low-carbon development of the building materials industry and have become common sustainability goals worldwide [1][2][3]. With accelerated urbanization and industrialization, large amounts of construction and demolition waste (CDW) are generated [4][5][6][7], which results in significant adverse effects on the environment and prevents the achievement of the dual-carbon target [8][9][10]. Therefore, reusing CDWs to mitigate environment pollution is necessary [11][12][13].…”

Three pretreatment methods including calcination, carbonization, and a carbonization-calcination combined pretreatment were studied to understand the pretreatment mechanisms for cement-based recycled powder (CRP). The mineral and microstructure of the CRP sample were investigated through X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), thermal gravity (TG) analysis, and scanning electron microscopy (SEM) after exposure to different thermal temperatures (400 °C, 600 °C, and 800 °C), carbonization times (6 h, 1 d, and 3 d), and pre-carbonization for 1 d followed by heating at 800 °C. The results showed that the optimal thermal pretreatment temperature was approximately 720–800 °C. Through the process of calcination, the C-S-H, Ca(OH)2, and CaCO3 minerals in the CRP sample underwent decomposition to produce CaO or C2S. During carbonation, the pretreatment not only results in the increased production of CaCO3 owing to the reaction of the C-S-H gel and Ca(OH)2 with CO2, but also enhances its properties and the strength of chemical bond between CaCO3 and the post-hydration products. Both CaCO3 and CaO were present after the combined pretreatment, which indicates that the CaCO3 mineral formed superior stability after it had been pre-carbonated. Due to fewer impurities in CRP, the positive effect of the pretreatment on CRP was significantly better than that on recycled powder derived from construction and demolition waste.
