By integrating ecosystem carbon sequestration models with economic contribution coefficients (ECC), ecological support coefficients (ESC), and China’s main functional zoning framework, we systematically analyze regional carbon sources and sinks and propose a spatially explicit optimization strategy. Results reveal a distinct “higher in the north than in the south, higher in the east than in the west” emission pattern, driven by economic agglomeration and energy structure, with industrial clusters such as Beijing–Tianjin–Hebei and the Yangtze River Delta acting as high-emission hotspots; notably, the Chengdu–Chongqing region exhibited a sharp emissions surge in 2022 due to accelerated industrialization. In contrast, carbon sequestration capacity forms a “northeast–southwest high axis,” enhanced by ecological restoration in regions like the Yellow River Basin but diminished along the eastern coast due to urban expansion, thereby exacerbating regional carbon imbalance. Based on ECC and ESC, we classify areas into four dynamically adjusted carbon balance zones: (1) low-carbon maintenance zones (e.g., Beijing–Tianjin–Hebei, Chengdu–Chongqing), characterized by strong economic output and carbon sink potential; (2) economic development zones (e.g., Central Plains, Shandong Peninsula), reliant on high-carbon industries yet underpinned by relatively sound ecological foundations; (3) carbon sink development zones (middle reaches of the Yangtze River), combining significant economic contributions with fragile ecosystems; and (4) comprehensive optimization zones (e.g., Hohhot–Baotou–Ordos–Yulin, Hexi Corridor), facing dual economic and ecological pressures. These are further refined into 16 sub-zones aligned with national functional zoning to enable targeted policy implementation. We recommend zone-specific strategies: consolidating low-carbon technologies and ecological advantages in maintenance zones; accelerating industrial decarbonization and energy efficiency in development zones; strengthening ecological restoration and green industry cultivation in sink zones; and fostering coordinated socio-ecological development in optimization zones through policy incentives, interregional collaboration, and market mechanisms. Ultimately, achieving nationwide carbon balance hinges on two core pathways: optimized land-use planning and the implementation of differentiated, spatially tailored policies that account for local socioeconomic and ecological contexts.</p></div>","PeriodicalId":505,"journal":{"name":"Carbon Balance and Management","volume":"21 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13527989/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148238586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing studies predominantly focus on macro-scales, overlooking county-level heterogeneity and future trajectories, thus limiting precise carbon balance management.

We introduce a novel framework that combines the Green Luenberger Productivity Index with the Bi-weighted Modified Russell Model (BWMRM), treating carbon emissions as an undesirable output. The results show that although overall ETFP remains relatively low, it exhibits a clear upward trend driven primarily by technological progress and carbon emission reduction efforts.

In addition, the input-output performance of labor exceeds that of capital and GDP, with significant regional disparities across countries. Based on these findings, we propose a four-dimensional policy framework. First, countries should establish a gradient mechanism for low-carbon transitions. Second, policymakers should optimize factor allocation to improve labor skills and the green use of capital.

However, existing research suffers from two critical gaps: first, a predominant focus on either carbon emissions or carbon absorption in isolation, rather than their equilibrium; second, a simplistic “point‑line” physical assessment of subways that overlooks network‑level accessibility and topology. This study addresses these gaps by adopting the carbon balance ratio (the ratio of terrestrial carbon absorption to anthropogenic emissions) as the outcome variable and employing Social Network Analysis to construct dynamic, station-level subway network centrality metrics in China. Empirical findings reveal that a one‑unit increase in county‑level subway network accessibility significantly improves the carbon balance ratio. This effect is strongest in economically underdeveloped regions, areas with compact spatial structures, and zones with lower residential electricity consumption. Mechanism analysis reveals a tri‑phase contribution: (1) during construction, subways preserve green space and carbon absorption capability by avoiding surface disruption; (2) during operation, they induce modal shifts that reduce transport emissions; and (3) through industrial transformation, their carbon benefits are amplified by supportive institutions, market mechanisms, and technological capabilities. By systematically integrating carbon balance measurement with network‑level subway accessibility, this study offers a comprehensive empirical framework and provides policy insights for integrating rail transit into low‑carbon spatial governance strategies.</p></div>","PeriodicalId":505,"journal":{"name":"Carbon Balance and Management","volume":"21 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13505065/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148175328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, saturation of remotely sensed signals remains a major challenge, often leading to the underestimation of AGB in high-density forests. In structurally complex forests, saturation in forest AGB mapping is influenced by multiple factors, including data sources, tree species, and modeling approaches. Although numerous methods have been proposed to mitigate saturation, a standardized metric for quantifying saturation and evaluating the effectiveness of these methods is still lacking. In this study, by separating saturation effects from mapping errors, SAT is proposed as a quantitative metric for assessing saturation in forest AGB mapping. The saturation levels of widely used and freely available Landsat 8 and Sentinel-1/2 remote sensing data were evaluated for forests dominated by ten common tree species in southern China. In addition, a quantitative analysis was conducted to examine the effects of multi-source data integration and nine different machine learning models on saturation levels. The results showed that tree species had a pronounced influence on estimation performance and saturation levels, with SAT values ranging from 48.15 Mg/ha to 147.93 Mg/ha. Integrated decision tree–based ensemble models produced more stable estimation results and higher saturation levels than single models. Moreover, texture features derived from optical images and Sentinel-1 data improved both the accuracy and saturation level of forest AGB estimation, with Sentinel-1 features showing a stronger contribution than texture features alone. Overall, the proposed SAT goes beyond conventional accuracy assessment by explicitly quantifying saturation-induced underestimation in high-biomass forests. This provides practical support for comparing sensor combinations and modeling strategies, and improves the reliability and interpretability of remote-sensing-based forest AGB products in dense forests.</p></div>","PeriodicalId":505,"journal":{"name":"Carbon Balance and Management","volume":"21 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s13021-026-00457-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148154814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by introducing environmental cost (EC) as a novel measure that quantifies the economic burden of environmental degradation. The need for the new measurement stems from the requirement to examine the non-linear and asymmetric behaviors of the relationship between the environment and the economy in rapidly developing economies such as the BRICS countries in their transition from fossil fuels, their drive for new types of innovation, and their increased susceptibility to sudden changes in the cost of degradation due to energy transition, innovation-related pressures, and vulnerability to sudden changes. Therefore, stabilizing mechanisms such as Energy Transition, Innovation, Environmental Adaptability, and Trade in Low-carbon Technologies (TLCT) will reduce the possibility of experiencing high levels of Environmental Cost, while Environmental Vulnerability (EV) will heighten the probability of experiencing catastrophic regime shifts to high-cost, unstable states with sudden and extreme changes in costs. To accomplish this objective of validating the Cusp-Logit framework, a balanced panel data consisting of the BRICS countries (Brazil, Russia, India and South Africa) for the years 2015 to 2024 is used. The hybrid model of the Cusp-Logit framework consists of the geometrical layout of the Cusp Catastrophe model and a stochastic Logit transition mechanism that will capture the nonlinear regimes of the Cusp Catastrophe model and the dynamic persistence of costs associated with environmental degradation. Although empirical evidence points to the stabilizing effects of energy transition, innovation, environmental adaptability and TLCT on flattening the potential surface and reducing the possible occurrence &amp; duration of high-cost regimes; EV creates a systemic tilt which increases the likelihood of a shift to an unstable/high-EC state. The cross-national analysis demonstrates that while China &amp; India have stable innovation-based environments; Brazil, Russia &amp; South Africa are much more susceptible to instability due to a limited ability to adapt to &amp; utilize technology. Given that there is currently no comprehensive framework for understanding environmental performance in terms of costs; this work develops a new methodology for modeling the dynamic behaviors of asymmetrical regimes as well as understanding the transition probabilities between them. This provides an early warning system, which will assist BRICS policymakers to manage their exposure to environmental risks while moving towards developing sustainable pathways with low cost. Unlike conventional emission-based and linear approaches, the proposed framework captures nonlinear regime shifts, transition probabilities, and persistence of environmental cost dynamics, offeri","PeriodicalId":505,"journal":{"name":"Carbon Balance and Management","volume":"21 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s13021-026-00458-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148136343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
