Carbon Emission Composition and Carbon Reduction Potential of Coastal Villages under Low-Carbon Background

Abstract

Rural buildings have high optimization potential as a major source of carbon emissions. However, the current research on carbon reduction in rural buildings is rough and lacks categorization and geographic studies. Coastal villages are more economically developed than other types of villages and have greater potential for energy saving. Therefore, this study takes the carbon emission data of buildings and life in 409 villages in typical coastal provinces of China as the basis and proposes optimization strategies for carbon reduction in coastal village buildings via cluster analysis and correlation analysis. The results show that the carbon emission characteristics of coastal villages can be categorized into three scenarios: for scenario 1, villages, their population, and village cultivated area are the core influencing factors of carbon emission, while for scenarios 2 and 3, the most central influencing factors are coal and electricity consumption. Therefore, different types of villages should be guided differently when studying carbon sinks and carbon emission projections in coastal villages. This study aims to establish a low-carbon performance quality assessment and optimization pathway for coastal villages, and the analysis of carbon emission influencing factors and the assessment and optimization provide theoretical support and quantitative methods for the optimization of carbon reduction in villages.

Assessment of CO2 Capture in FA/GGBS-Blended Cement Systems: From Cement Paste to Commercial Products

“…As shown in Figure 11, the blended binders are mixed with coarse and fine aggregates in the plant to produce the bricks, followed by carbonation curing using waste CO 2 gas. The life cycle assessment of the embodied carbon emissions also includes the transportation and construction process (Figure 11) [56]. The embodied carbon emissions from the captured CO 2 by the bricks made of different blended cements can be calculated based on the estimation from Equation (2) (as given in Figure 10) with the consideration of the carbonation depth of the cured bricks (Section 2.3).…”
