Investments in green energy are increasing exponentially due to rising environmental concerns. Our work scrutinizes the influence of decomposed structural oil shocks on the green bonds in developed countries from November 28, 2008 to May 21, 2021. We use contemporary time-varying methodologies including nonlinear causality and rolling window wavelet correlation tests. We find that green bonds remain strongly correlated with demand and supply shocks in the long run, particularly the green bonds in the UK, US, Japan, and Switzerland during the crisis periods. Japan shows a strong positive correlation with demand shocks over the long run but negative correlation in the short run. In contrast, Norway, New Zealand, and Sweden's green bonds have a positive correlation with supply and demand shocks during the short-run period. Our results carry useful implications for investors and policymakers.

The impact and mechanism of hydrological connectivity and dissolved organic matter on the fate of nitrogen and antibiotics are still lack off in a river-lake connected system under climate extreme events. This study examined the fate of NO3−-N, 38 antibiotics, and dissolved organic matter (DOM) in Baiyangdian Basin, through dry and wet seasonal (after extreme rainfall) samplings at 2023. In the system, NO3−-N and ∑antibiotics average concentrations were higher in the dry season, while the relative abundance of humic-like components was higher in the wet season. Spatial autocorrelation analysis showed that the high-high clusters of pollutants and DOM components were mainly distributed in rivers, and the temporal difference was significant. MixSIAR and PMF model were respectively applied to nitrogen and antibiotics sources apportionment. The results showed that non-point sources (NPS) of nitrogen and antibiotics exhibited an upward trend, while the point sources decreased from dry to wet seasons. Hydrological connectivity was characterized by using δ18O-H2O, which was higher in the wet season. Partial least squares path model revealed that hydrological connectivity directly impacted humic-like components, which were the direct influencing factor of the concentration and NPS for antibiotics and nitrogen in the connected system. Extreme rainfall weaken the impact of hydrological connectivity on the concentration and NPS of pollutants, while enhanced the impact of humic-like components on pollutants NPS. These findings clarified the impact mechanism of hydrological connectivity and DOM on nitrogen and antibiotics fate in the connected system, which plays an important role in future water quality management under extreme events.
在气候极端事件下的河湖连通系统中，水文连通性和溶解性有机物对氮和抗生素归宿的影响和机理尚缺乏研究。本研究通过2023年干湿季节（极端降雨后）取样，考察了白洋淀流域氮、38种抗生素和溶解有机物（DOM）的去向。在该系统中，旱季NO3--N和∑抗生素的平均浓度较高，而湿季腐殖质类成分的相对丰度较高。空间自相关分析表明，污染物和 DOM 成分的高-高集群主要分布在河流中，且时间差异显著。将 MixSIAR 和 PMF 模型分别用于氮源和抗生素源的分配。结果表明，氮和抗生素的非点源呈上升趋势，而点源从旱季到雨季呈下降趋势。利用 δ18O-H2O 表征水文连通性，结果发现雨季的水文连通性更高。偏最小二乘法路径模型显示，水文连通性直接影响腐殖质样成分，而腐殖质样成分是连通系统中抗生素和氮的浓度和 NPS 的直接影响因素。极端降雨削弱了水文连通性对污染物浓度和净磷（NPS）的影响，而增强了类腐殖质成分对污染物净磷（NPS）的影响。这些发现阐明了水文连通性和 DOM 对氮和抗生素在连通系统中归宿的影响机制，对未来极端事件下的水质管理具有重要作用。

Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants primarily emitted by heavy industry, while their relationship with light industry has remained largely overlooked. This study quantified 16 priority PAHs in sediments from an urbanized river and its tributaries using gas chromatography coupled with triple quadrupole mass spectrometry, assessing the impact of local light industries. The total sedimentary PAH concentrations ranged from 244 to 24,616 ng/g dw (mean: 2097 ± 2673 ng/g dw), with high molecular weight PAHs predominating. PAH concentrations closely mirrored the operational footprint of the textile and shipping industries, including significantly higher PAH concentrations in the midstream compared to the upstream and downstream areas with fewer industrial activities. Additionally, PAH concentrations were significantly higher in the rainy season in the semi-closed lakes than in the dry season and normal season, likely due to increased industrial production and shipping activity, combined with the periodical closure of sluice gates that restricts the outflow of PAHs from connected lakes to the main watercourse. Multiple statistical analyses revealed that coal and petroleum combustions, primarily from these local industries, contributed 88% to the sedimentary PAH load, while vehicle exhausts and oil leakages accounted for the remaining 12%. According to sediment quality guidelines, PAHs exhibited pervasive ecological risks, even near drinking water sources. This study highlights the substantial influence of industrial activities on PAH distribution in urbanized rivers and provides a robust theoretical foundation for energy transition and drinking water protection strategies.

Accurate measurement of the ecological carrying capacity of sports tourism is the core point to achieve sustainable development of sports tourism, maintain ecological balance and improve the quality of tourist experience. This study investigates the ecological carrying capacity of sports tourism in Rizhao City, China, using a "carrier-load" integration perspective and a multi-scale spatiotemporal approach. The research divides Rizhao City into two distinct regions: the Mountainous Hills Sports Tourism Region (MSTR) and the Coastal Plains Sports Tourism Region (CSTR). By analyzing 16 key indicators, including vegetation cover, water conservation, sports tourism revenue, and carbon footprint, the study evaluates the dynamic interplay between ecological carriers (natural resources) and tourism loads (human activities). The results reveal significant spatial and temporal variations in Ecological Carrying Capacity of Sports Tourism (STECC). The MSTR exhibits a stable STECC index around 1.6, indicating strong ecological resilience but with signs of slight overloading during peak seasons. In contrast, the CSTR shows a higher STECC index ranging from 2.6 to 2.94, reflecting severe ecological overloading due to intense coastal tourism activities, particularly in summer. The study highlights the critical need for targeted ecological protection measures in the CSTR, such as controlling tourist numbers and enhancing ecological restoration, while leveraging the MSTR's potential to alleviate pressure on the coastal region. These findings provide a scientific basis for sustainable sports tourism development, emphasizing the importance of balancing ecological preservation with tourism growth. The research contributes to the theoretical framework of STECC assessment and offers practical insights for regional tourism planning and ecological management.

Medium-term effects of different organic amendments on the recovery of mining-degraded soils in a semi-arid limestone quarry were evaluated. Five organic amendments, including composts (garden pruning and greenhouse residues) and stabilised sewage sludge (alone and in mixtures), were compared to untreated soils and natural reference soils. After 40 months, different soil physico-chemical properties, total nutrient (organic carbon –C–, nitrogen –N– and phosphorus –P–) and labile P and N fractions were analysed together with bacterial functional groups catalysing major steps in P (phoD, appA, phnX, pstS) and N turnover (chiA, archaeal amoA, bacterial amoA, nirS, nirK, nosZ, nifH), as well as total bacterial biomass. Restoration altered soil properties, including decreasing pH by up to 10% and increasing total organic C (up to 3.54%), total N (up to 0.33%) and total P (up to 0.18%). Labile P- and N-fractions increased significantly, with ammonium and nitrate doubling in some cases. Microbial activity also rose significantly, with bacterial biomass and functional genes involved in P (phoD, pstS) and N turnover (chiA, nirS, nosZ) increasing 2–3000 times compared to non-restored soils. Sewage sludge had the most pronounced effect on physico-chemical properties, nutrient content and functional groups abundance, while greenhouse compost produced conditions resembling natural reference soils. These results demonstrated that organic amendments can rehabilitate degraded soils by enhancing nutrient content and bacterial community potential for N and P turnover. Organic amendments are thus a viable strategy for medium-term restoration of degraded soils in semi-arid climates.

Phytocapping offers a sustainable approach for managing exposed tailings by mitigating pollutant spread and enhancing phytoremediation. This study investigates the potential of Bermudagrass (Cynodon dactylon) as a pioneering plant for rehabilitating tailings from an open-pit lead-zinc mine in Southwest China. Our findings demonstrate that Bermudagrass significantly improved soil quality and multifunctionality compared to adjacent bare tailings. Soil improvements included increases in organic matter (107%), total and available nitrogen (50% and 110%, respectively), available phosphorus (170%), and soil enzyme activities, including β-glucosidase (170%), sucrase (1729%), alkaline phosphatase (3722%), and acid phosphatase (168%). The reclamation process also promoted microbial community succession, altering community composition, improving microbial diversity, and enhancing bacterial biomass from (0.89 ± 0.54) × 1015 to (9.06 ± 3.25) × 1015 copies/g in rhizosphere soils. Greenhouse experiments further confirmed Bermudagrass's resilience to cadmium (Cd), with both mining and non-mining ecotypes thriving in tailing soils and Cd2+ hydroponic solutions (up to 44.5 μM) without evident phytotoxicity. Bermudagrass roots exhibited exceptional Cd accumulation (bioconcentration factor: 181–1006) while minimizing Cd translocation to shoots (translocation factor: <0.13). Inoculation with Funneliformis mosseae, a restored root-mutually symbiotic fungus, further mitigated Cd-induced phytotoxicity and enhanced plant growth. These findings highlight Bermudagrass as a promising pioneer species for phytostabilization in severely contaminated mining environments, with its rhizosphere microbiome playing a critical role in facilitating ecosystem restoration. Sustainable plant establishment in mine waste rock requires concurrent development of belowground fertility and healthy rhizospheric soil. Ultimately, successful revegetation depends on integrated above and belowground development to achieve long-term ecological restoration.

Coal phase-down (CPD) is critical for climate mitigation and impacts resource use and environmental emissions, key to achieving the Sustainable Development Goals (SDGs). As the world's largest coal consumer and producer, China's decarbonization significantly influences global energy transitions and SDG fulfillment. This study employs an integrated assessment model to evaluate the impacts of CPD on energy systems, resource use, environmental quality, and SDG progress. The analysis is conducted under five scenarios: BAU (Business-As-Usual), Cost-CPD (cost-driven), Tech-CPD (technology-driven), CoalGrowth (coal expansion), and two temperature control pathways (1.5 °C and 2 °C). Our analysis shows that CPD scenarios lead to a more favorable transition in the energy system, enhanced mitigation of environmental emissions, and improved resource efficiency. Results show considerable variation across SDG scores. Notably, SDG7 achieves the most significant improvement, whereas SDG2, SDG6, and SDG15 show limited or even regressive progress. CPD pathways foster synergies among SDG targets, particularly SDG7 and SDG13, with both Tech-CPD and Cost-CPD contributing by improving energy efficiency, and reducing emissions, thereby driving progress on both SDG7 and SDG13.These findings provide valuable insights for shaping CPD policies and promoting sustainable development.

As an important indicator of a firm's commitment to its stakeholders, ESG's impact on the intra-firm pay gap remains underexplored. This study examines the relationship between ESG performance and the intra-firm pay gap using a sample of Chinese-listed companies from 2009 to 2022. We find that high ESG performance is significantly associated with the widening of the intra-firm pay gap. Further analysis indicates the increasing gap mainly comes from escalating management compensation, while the rank-and-file employees' salaries remain unchanged. We explore three mechanisms behind the above relationship: reducing agency costs, enhancing managerial capabilities, and improving managerial reputation. Furthermore, our analyses suggest that the effect of ESG performance on the intra-firm pay gap is intensified when the majority shareholder wields greater influence and rank-and-file employees have less bargaining power. This study has essential policy implications for understanding the impact of ESG practices on income distribution within firms.

We explore three mechanisms behind the above relationship: reducing agency costs, enhancing managerial capabilities, and improving managerial reputation. Furthermore, our analyses suggest that the effect of ESG performance on the intra-firm pay gap is intensified when the majority shareholder wields greater influence and rank-and-file employees have less bargaining power. This study has essential policy implications for understanding the impact of ESG practices on income distribution within firms.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"378 ","pages":"Article 124748"},"PeriodicalIF":8.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527490","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}

The majority of NW European peatlands are degraded due to conventional grassland-based livestock farming (i.e. lowered groundwater levels, high nutrient inputs and high mowing frequencies) leading to increased CO2 emissions and soil nutrient levels, and reduced biodiversity. Creating regenerative ditch borders along drainage ditches that surround agricultural fields could ameliorate some of these negative effects. We investigated the effects of ditch border type (conventional vs. regenerative) on litter decomposition (standardized litter using Tea Bag Index, and locally collected leaf and root litter), vegetation composition, litter quality, and soil characteristics along transects that extended from the water's edge into the adjoining field (40 cm, 80 cm, 360 cm and 640 cm) in a peat polder in North Holland, the Netherlands. The decomposition rate of standardized litter was unaffected by ditch border type, however the stabilization factor was 43% and 35% lower in regenerative ditch borders at 40 cm and 80 cm from the water's edge, respectively. Leaf litter collected from regenerative borders decomposed 75% slower than leaf litter from conventional borders. Regenerative soils were higher in organic matter content, carbon and nitrogen content, and soil moisture content, and lower in bulk density and soil compaction. This pattern was related with a lower decomposition rate and stabilization of standardized litter. Changes in litter decomposition are predominantly driven by a lower leaf litter quality produced at regenerative borders. Efforts to reduce carbon emissions should therefore focus on reducing decomposition rates by creating conditions that stimulate plant species producing litter of a lower quality.

Superoxide radicals (·O2−) has been regarded as one of the reactive oxygen species (ROS) for the elimination of complex contaminants via electro-Fenton like (EF-like) technology. However, the generation path of ·O2− is diverse, and the influence of the physicochemical properties of metals on the mechanism of ·O2− conversion is significant in the EF-like treatment of wastewater. Herein, metals (M = Mn, Cu) loaded zeolitic imidazolate frameworks catalytic materials (M–NC) were prepared for sulfamethoxazole (SMX) removal to analyze the effect of metals on the pathways of ·O2− generation. The removal kinetic rate of SMX by Cu–NC was 1.32 times higher than that of Mn–NC. Quenching experiments demonstrated that ·O2− is the most important oxidizing species to achieve SMX removal. The RRDE measurements and quantitative experiment on the concentration of H2O2 experiments indicated that Mn–NC was more inclined to generate ROS through activation of H2O2 and Cu–NC through other ways. Therefore, the transformation pathways of ·O2− in different catalytic systems were thoroughly analyzed. Electron paramagnetic resonance test and reactive oxygen species quenching experiments indicated that the pathway for ·O2− production of Mn–NC was O2 → H2O2 → ·O2−, and that of Cu–NC was O2 → ·O2−. The strategy of using Mn and Cu-based catalysts to investigate the mechanism of the ·O2− generation pathway provided a way to efficiently utilize the conversion of ·O2−.
