As one of the most vital terrestrial ecosystems, farmland ecosystems play an irreplaceable role in balancing carbon emissions and absorption, attracting growing scholarly attention. Taking Jiangsu Province, one of China's major grain-producing regions, as the study area, this research integrates the Slacks-Based Measure (SBM) model, the entropy-weighted method, and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to analyze the spatiotemporal evolution of farmland carbon effects-including carbon emissions, carbon absorption, and net carbon sequestration-during 2011-2021. Furthermore, a Grey Prediction Model was employed to forecast the carbon effects of 13 cities over the next 12 years. The results show that Jiangsu's farmland carbon emission efficiency exhibited an overall upward trend with fluctuations, with an average value of 0.76. The multi-year mean fitting degrees of resource input and agricultural output were relatively low, at 0.426 and 0.358, respectively, with substantial intercity differences. The average coupling coordination degree between resource input and agricultural output was 0.66, indicating a primary coordination state. The constructed GM (1,1) model achieved a qualification rate exceeding 73.80%, demonstrating its reliability for predicting farmland carbon effects. Forecasts suggest a potential weakening of the province's agricultural carbon sink effect, with the net carbon sequestration in 2033 expected to decline by 15.55% compared with the maximum value during the observation period. This study reveals the spatiotemporal characteristics and potential evolution patterns of farmland carbon effects, providing theoretical support for region-specific agricultural emission reduction policies and promoting the sustainable development of efficient, low-carbon agriculture.</p>","PeriodicalId":505,"journal":{"name":"Carbon Balance and Management","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147832039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a comprehensive measure of coordination within the \"energy-economy-environment\" system, EEE effectively captures a country's or region's ability to harmonize energy consumption, green and sustainable development, and environmental protection. This study computes the EEE index using the SBM model and examines how a carbon emission trading pilot policy (CETPP) affects EEE in China and its spatial spillover by employing a difference-in-differences (DID) model and spatial econometric model. The results indicate that CETPP implementation significantly enhances regional EEE and advances China's green and low-carbon transition process by improving the balance between economic and environmental goals, increasing employment, diversifying the energy supply, and strengthening economic resilience. Mechanistic research reveals that the CETPP promotes the improvement of EEE by reducing pollution emission intensity and that regional innovation ability can enhance the positive impact of the CETPP on regional EEE. Further analysis revealed significant endogenous spatial interactions in EEE across Chinese regions. However, EEE in the eastern and western regions can create a \"siphon\" effect on production factors that hinders development in neighbouring areas. Implementing a CETPP in a region not only advances local EEE but also stimulates EEE improvements in adjacent areas, with the strongest spillover effect observed in eastern China. To this end, it is essential to enhance the management of carbon dioxide emissions, actively advance the establishment of carbon trading markets.

This study uses 914 site years of data across 132 flux tower sites in the FLUXNET2015 dataset to explore the relationships between carbon sequestration, expressed by Gross Primary Productivity (GPP), and multiple phenological variables, including LGS, changes in SOS (ΔSOS), and changes in EOS (ΔEOS). LGS explains 23% of the variability in GPP across all sites. Significant correlations were found in deciduous broadleaf forests (R² = 0.5) and evergreen needleleaf forests (R² = 0.44), while ecosystems such as shrublands, savannas, and wetlands displayed weaker connections. Changes in the SOS also affected GPP, with an earlier SOS increasing the total annual GPP. Deciduous Broadleaf Forests (R² = 0.54), Evergreen Needleleaf Forests (R² = 0.5), Grasslands (R² = 0.47) showed a significant negative association between ΔSOS and ΔGPP, whereas Croplands showed weaker correlations. Conversely, EOS variations had little impact on GPP.

This study develops a Digitalization Index of Urban Elements (DIUE), encompassing labor, capital, and energy, to examine its association with CTFP in 213 Chinese cities from 2011 to 2023. CTFP is measured using an undesirable-output slacks-based measure, and the empirical analysis employs a two-step system GMM with Windmeijer correction, mediation analysis, spatial-lag models, and dynamic panel threshold tests. Robustness checks utilize an alternative productivity index and a difference-in-differences design based on early smart-city pilots. Three key findings emerge. First, factor-level digitalization is positively associated with urban CTFP; a one-standard-deviation increase in DIUE corresponds to a 1.5-1.7% increase in CTFP, which accumulates to approximately 4% in the long run. Second, this relationship is primarily mediated by green innovation, accounting for approximately 47% of the mediated effect, while industrial upgrading and agglomeration provide additional support, accounting for about 24% and 6%, respectively. Third, the benefits of digitalization exhibit both spatial spillovers and conditional effects: the indirect spillover effect constitutes roughly one-third of the direct effect, and positive gains are more pronounced in contexts with lower labor and capital misallocation and stronger local low-carbon commitment. By integrating a transparent and replicable measure of factor digitalization with evidence on its underlying mechanisms, spatial spillovers, and activation thresholds, this study clarifies the conditions under which digitalization can be effectively translated into enhanced carbon productivity. The policy implication is that cities should complement digital investment with measures to reduce factor misallocation, strengthen low-carbon commitment, and foster innovation.</p>","PeriodicalId":505,"journal":{"name":"Carbon Balance and Management","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147809433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although considerable research has independently examined construction land growth control and regional carbon emission assessments, few studies have integrated these aspects to guide construction land expansion within the framework of carbon peaking strategies. This study proposes an innovative framework that integrates carbon emission considerations into the management of regional construction land expansion. Using Changsha City as a case study, this research analyzes the spatiotemporal dynamics of construction land expansion and associated carbon emissions from 1990 to 2020, exploring their interdependencies. To project future trends, three scenarios-natural growth, high-emission expansion, and low-emission development-were developed to simulate the impacts of construction land changes on carbon emissions by 2030. The study evaluates the carbon emission consequences of urban expansion and proposes mitigation strategies within a low-carbon development framework. The findings indicate that: (1) From 1990 to 2020, construction land in Changsha City expanded by 660.24 km², primarily encroaching upon adjacent cultivated and forested lands. During the same period, carbon emissions increased by 1.3963 × 10⁸ t, showing a strong positive correlation with construction land expansion; (2) By 2030, carbon emissions are projected to reach 2.396 × 10⁸ t, 2.582 × 10⁸ t, and 1.639 × 10⁸ t under the natural growth, high-emission, and low-emission scenarios, respectively, reflecting increases of 53.21%, 65.11%, and 4.81% relative to 2020 levels; (3) Under both the natural growth and high-emission scenarios, construction land expansion is likely to intensify its adverse impact on the regional ecosystem, thereby reducing ecological stability. In contrast, the low-emission development scenario is projected to promote significant improvements in ecosystem health and resilience.

Accordingly, a theoretical framework for water-energy-carbon accounting and inter-regional transfer based on land use was established. Then the water and energy use and carbon emissions of cropland, forest land, grassland, water area, and construction land in 30 Chinese provinces were estimated and their spatial-temporal patterns were analyzed.

The energy-carbon transfer patterns driven by embodied land flow were similar. Embodied land consumption was concentrated in cropland, forest land, and grassland. Water consumption driven by embodied land flow was primarily concentrated in cropland. Energy consumption and carbon emissions driven by embodied land flow were mainly concentrated in construction land. Generally, the embodied land flow-related water-energy-carbon transfer efficiency has improved, with the proportion of efficient transfer increasing by 2.03%, 2.08%, and 2.82%, respectively.

Emissions were estimated over 100 years from the year of the original HWP disposal. For solid HWP, the climate warming effect decreased, for any given recycling fraction, as the landfill fraction decreased. The opposite, however, occurred for paper HWP. Recycling reduced the climate warming effect of solid HWP by \"pushing\" some of the emissions outside of the assessment period. For paper HWP, recycling did not change the climate warming effect unless the assessment period was relatively short.
