Abstract
Embodied carbon emissions (ECE) from in-use steel stocks (IUSS) are crucial for urban sustainability and climate goals, yet relevant spatiotemporal information is still lacking. This study employs multi-source spatiotemporal data to develop a dynamic estimation method, evaluating the spatiotemporal dynamics of IUSS-ECE across 67 countries along the Belt and Road (B&R) from 1992 to 2020. The results indicate that a significant increase in IUSS in the B&R region led to a 24 GtCO2 rise in ECE between 1992 and 2020, with 2005 marking a turning point for accelerated growth. ECE intensity per unit area increased from 3.4 to 5.9 ktCO2/km2, mainly in eastern B&R regions. Spatiotemporal analysis reveals the area convergence effect in ECE across the B&R, indicating that geographical relationships significantly influence ECE evolution. Additionally, the study emphasizes the significance of short-process steelmaking technology, clean energy supply, and promoting cross-regional resource circulation for the decarbonization of IUSS.
期刊介绍:
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
