Summary
China's residential buildings show increasing operational carbon emissions, posing a challenge to carbon peak goals. Decarbonization efforts vary regionally, with northern and southwestern China demonstrating higher efficiency.
Area of Science:
- Building energy and environmental performance
- Climate change mitigation strategies
- Sustainable urban development
Background:
- China's extensive residential building stock contributes significantly to operational carbon lock-in, hindering the 2030 carbon peak target.
- Understanding provincial variations in carbon emissions and decarbonization is crucial for effective climate policy.
Purpose of the Study:
- To analyze provincial carbon changes in residential building operations from 2000 to 2018.
- To identify key factors driving carbon emissions and decarbonization progress.
- To assess decarbonization efficiency across different regions of China.
Main Methods:
- Development and application of the Generalized Divisia Index Method using an 8x14 matrix.
- Analysis of fourteen factors influencing provincial carbon emissions in residential buildings.
- Examination of temporal trends in decarbonization from 2000 to 2018.
Main Results:
- Operational carbon emissions from residential buildings increased by an average of 4.53% annually, driven by expanding floor areas.
- Decarbonization peaks occurred before 2008 in Northern China, around 2014 in Central/Eastern China, and continued to grow in Southern China.
- Northern and Southwestern China exhibited high decarbonization levels (35.06 MtCO2/province) and efficiency (7.05%/province) between 2001-2018.
Conclusions:
- The study refines methods for assessing building operational decarbonization.
- Findings provide insights for governments to investigate building decarbonization potential and implement effective climate policies.
- Regional disparities in decarbonization highlight the need for tailored strategies to achieve China's carbon peak goals.

01:24Carbonation Shrinkage
203
Atmospheric CO2 penetrates the concrete's pores and, in the presence of moisture, forms carbonic acid, which then reacts with calcium hydroxide in the hydrated cement, forming calcium carbonate. This process reduces the concrete's volume and is termed carbonation shrinkage.
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction...

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...
