Drawing on signaling theory and the financing pricing behavior of risk-averse creditors, this study develops a micro-level theoretical model within a game-theoretic framework to explain the incentives for firms to adopt greenwashing behavior (GW) under ambiguous ESG signals. The theoretical analysis suggests that moderate information asymmetry may help reduce financing costs and generate implicit financing dividends, whereas excessive GW may result in regulatory penalties and reputational risks. Based on this framework, the study constructs a firm-level ESG disclosure uncertainty (ESGU) index and conducts an empirical analysis using data from A-share listed companies in China (from 2009 to 2022). The results show that greater ESGU increases the likelihood of firms engaging in GW-emphasizing green narratives while obscuring actual environmental performance. Further analyses reveal that firms with higher debt financing costs, greater information asymmetry, and stronger resource dependence are more likely to leverage ESG signal ambiguity to \"appear green.\" Heterogeneity signifies that audit quality and financial pressure substantially influence the intensity of ESGU on GW. Moreover, GW is found to significantly alleviate firms' financing constraints. A nonlinear relationship is also identified between ESGU and financing constraints, indicating the existence of a marginal \"fuzzy arbitrage\" window. This work offers theoretical and empirical evidence for the economic rationale linking ESG disclosure ambiguity to GW, thereby enhancing the literature on green signaling, strategic compliance, and sustainable finance. The results provide actionable insights for enhancing ESG governance in financial markets and promoting high-quality, sustainable development.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"394 ","pages":"127473"},"PeriodicalIF":8.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Given rising concern over the ubiquity, persistence, and harmful effects of plastics, it follows that researchers are modeling global microplastic fluvial fluxes in an effort to understand the source, transport, and fate of plastic in the environment. However, there are significant data gaps contributing to uncertainty in flux estimates, including selective particle bias introduced through collection methods, failure to account for flow-field variation, and poor characterization of concentrations across the discharge regime. Furthermore, these types of models do not translate well to the local watershed scale, where the potential utility of accurate flux data is the highest. To address this, we modeled the microplastic concentration-discharge behavior near the outlets of two tributaries to Upper Newport Bay, California, USA, using samples collected as part of a flow-integrated fluvial monitoring campaign. Representative microplastics concentrations collected from a range of flows were paired with streamflow discharges and fit with rating curves. By integrating over the 2021 Water Year discharge record, we calculated a total flux to the Bay of 23-41 billion microplastics and found that despite the infrequency of rainfall in the region, the majority of the total microplastic load was transported during stormflows at each site.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"394 ","pages":"127445"},"PeriodicalIF":8.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This research examines how strategically integrating digitalization with green innovation can reconcile this tension, thereby transitioning economies from resource reliance to environmental resilience. Analyzing panel data from 2000 to 2021 through advanced econometric frameworks, we identify three pivotal mechanisms. First, while natural resource rents and economic growth amplify emissions, renewable energy adoption emerges as a consistent decarbonization lever. Second, although digitalization and green innovation may initially increase emissions during transitional phases, their interaction with resource extraction ultimately exerts mitigating effects, revealing latent compensatory pathways. Third, their combined deployment generates synergistic reductions, with effects magnified in high-emission contexts. Methodologically, the Cross-sectional Augmented Autoregressive Distributed Lag (CS-ARDL) framework captures dynamic equilibrium adjustments, while the Method of Moments Quantile Regression (MMQR) estimation highlights context-dependent heterogeneities. These findings advance a co-evolutionary policy framework, demonstrating how BRICS + economies can orchestrate technological interoperability to bypass traditional tradeoffs between resource reliance and sustainability. We advocate for integrated innovation strategies rather than fragmented interventions. By aligning digital and green transitions, this systemic approach generates compounded benefits, offering a viable paradigm for emerging economies balancing development and decarbonization imperatives.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"394 ","pages":"127498"},"PeriodicalIF":8.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study investigates legacy trace element (TE) contamination (Ag, Bi, Cd, Cu, Hg, Pb, Sb, Sn, Zn) in sediments from the Loire river and its main tributaries, highlighting contamination hot periods and hotspots over eight decades. Prior to the 1950s, sediment composition was stable but limited localized contamination was already identified. During the 1950s-1970s, TE enrichments spread basin-wide, driven by industrial and mining activities plus active sediment transport. River modifications such as dam construction and intensive sand mining started to intensify in the 1970s. From the 1980s onward, TE concentrations globally declined due to regulatory measures, industrial closures and sediment connectivity disruptions caused by sand mining, dams and weirs, confining contamination hotspots mostly within sub-basins.

To address the limitations of the traditional manual selection method, this study proposed an optimal selection method for CDW crushing equipment based on deep learning. Firstly, a rapid assessment method for the size and volume of CDW based on deep learning was proposed. Specifically, the Mask R-CNN model was employed to identify and segment the CDW at the demolition site. Thereafter, the size distribution and mass distribution of the CDW were calculated based on the segmentation results, using the Brute Force algorithm and the 3D volume reconstruction method, respectively. Secondly, the size distribution of the CDW was combined with the discharge size requirement for recycled aggregates to determine the optional crushing equipment that can meet the CDW production requirements. Finally, the environmental emissions of optional crushing equipment were calculated based on life cycle assessment (LCA) and converted to environmental costs based on the social willingness to pay (WTP). Subsequently the optimal crushing equipment for CDW was determined by combining running costs and environmental costs. The results demonstrated that the Mask R-CNN model employed in this study exhibited superior accuracy in comparison to other segmentation models. The overall error in the size distribution and mass distribution was maintained within 5 %. The method of this study can determine the optimal crushing equipment for CDW and provide auxiliary decision support for actual recycling projects.

In this study, an efficient treatment for the remediation of petroleum-contaminated soil comprising directional oxidation was constructed based on the enhancement of SOM stability. A mechanism was proposed whereby SOM pretreatment with hydrogen peroxide (HP) produced more binding sites, such as O-H, C=O, and C-O, thereby making SOM to be maximally stabilized by forming OM-Al-mineral complexes after adding aluminum salts (AS). The two-dimensional correlation spectroscopy (2D-COS) of the FTIR spectra certified that C-O was more sensitive to HP pretreatment and Al cross-linking. Specifically, the enhancement of SOM stability improved the relative reactivity of ROSs to total petroleum hydrocarbons (TPHs) (k<sub>TPHs</sub>), driving approximately 30 % of the ROSs to be transferred for the directional oxidation of TPHs. Under such conditions, the directional oxidation amount of TPHs by activated persulfate was up to 13,083 mg/kg (53.55 %), equivalent to 2.67, 1.82, and 1.39 folds of the control CK, HP, and AS treatments, respectively. Subsequently, indigenous bacteria degraded 10,969 mg/kg (44.90 %) of TPHs during a 60-day incubation.
