These challenges necessitate a transformative approach, particularly the adoption of circular economy (CE) practices, to mitigate adverse impacts and promote sustainability in the sector. This research aims to identify and evaluate the important enablers, sub-enablers, and scenarios for the adoption of CE practices to enhance environmental sustainability in sports industry. This study used the Delphi method to identify the key enablers, sub-enablers, and scenarios. Later, the Analytical Hierarchy Process (AHP) method is used to evaluate and prioritize these pertinent enablers and sub-enablers to the sports sector. Finally, the fuzzy Weighted Aggregated Sum Product Assessment (WASPAS) method is used to rank the six important scenarios for the adoption of CE practices in the sports industry. The results of AHP shows that regulatory pressures, consumer demand, and corporate social responsibility are the most dominant enablers that affects the adoption of CE practices. The fuzzy WASPAS findings showed that standardization and certification schemes, CE roadmaps and action plans, and extended producer responsibility are the key scenarios in adopting CE practices and environmental policy frameworks in sports products industry. This research provides actionable insights for policymakers and industry leaders to encourage the adoption of the CE implementation and environmental sustainability within sports sector.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"372 ","pages":"Article 123306"},"PeriodicalIF":8.0,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662733","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}

Focusing on the Den-en-toshi Line, which spans Tokyo and Kanagawa Prefecture, as a case study, we developed a sustainable TOD assessment model based on the node-place-ecology (NPE) framework. This model was used to analyze the dynamic changes in different TOD circles from 2011 to 2019. The results indicate a positive sustainable development trend in the first and second circles, while the third circle shows a slight decline. Moreover, a comparison between urban and suburban areas further supports the notion that the monopolization trend of core stations in Tokyo is intensifying. We believe that the model framework developed in this study has great adaptability and can be widely applied globally to help researchers and urban planners conduct more accurate sustainability assessments of TOD stations.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"372 ","pages":"Article 123274"},"PeriodicalIF":8.0,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662734","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}

Moreover, it determines if this impact varies across enterprises of different natures, resource allocation capabilities, and geographical regions. Furthermore, we will explore how GTI affects the ESG performance of companies through internal and external mechanisms. We empirically examine these issues through panel models using a sample of 3203 Chinese manufacturing firms with 28,334 observations from 2006 to 2022. The findings reveal that (i) GTI significantly enhances firms' ESG performance; (ii) market-based environmental regulation positively influences the relationship between GTI and ESG performance; (iii) GTI contributes to improving a firm's ESG performance by reducing carbon emission intensity; and (iv) the impact of GTI on firms' ESG performance is notably pronounced among non-state-owned enterprises, those with high green total factor productivity, and firms in the central region.

The composition of aquatic macroinvertebrate assemblages differed significantly between the depression and slope wetlands.

However, its scalability is limited due to challenges in model generalization across different forest types and regions. The selection of sensitive variables from ALS data is crucial for constructing robust forest AGB estimation models, yet this selection varies significantly among forest types and regions. Traditionally, assessing the influence of variable selection is hindered by the lack of accurate reference forest AGB values. Computer simulation-based method provides a perspective for exploring these challenges. This study employs an individual-based forest growth process model, FORMIND, coupled with a 3D radiative transfer model (RTM), LESS, to evaluate the transferability of ABA-based forest AGB estimation models and the generalization of ALS-derived variables. We used six virtual 3D forest scenes and two real-world forest sites, representing a range of global forest types, along with their simulated ALS data, to develop a forest AGB estimation model using the random forest algorithm, which allowed us to analyze the importance of various variables. We assessed model transferability through cross-comparison. Additionally, we validated the model using field plots and ALS data collected from two distinct regions. The results showed that the canopy surface area and volume extracted using the α-shape algorithm and parameters fitted from the Weibull distribution are vital variables when using ALS for forest AGB estimation across forest types and regions. Incorporating these variables into the model significantly improves the accuracy of forest AGB estimation. The optimized model achieved a R² of 0.945, a RMSE of 34.22 t/ha, and a MAE of 20.53 t/ha.

We employed the Integrated Valuation of Ecosystem Services and Tradeoffs model to simulate the WCS value in the Nianchu River Basin and used the Minimum Cumulative Resistance model in combination with the Linkage Mapper to construct an EN. Through topological analysis based on complex network theory, we examined the EN topology and identified ecological pinch points and barriers by applying circuit theory.

Seven pure cultures were isolated and then tested for being able to grow on a mineral medium in the presence of terpene vapor as the only source of carbon and energy. Three of the most actively growing cultures were selected, characterized and identified by the 16S rRNA gene as <em>Rhodococcus erythropolis</em> CA1, <em>Rhodococcus pyridinivorans</em> CA3 and <em>Gordonia</em> sp. CA6. Three identical laboratory biofilters (BF) were inoculated with a mix of these cultures to test the possibility of more complete removal of terpenes. Biofilters were adapting to clearing the model mix of terpineols and geraniol vapors for 45 days. During 45 days the purification efficiency of the model mix reached an average of 91.5% with a contact time (CT) of 3.7 ± 0.2 s and the terpene vapors concentration of 14 ± 2 mg m⁻³. Then the biofilters number BF2.1 and BF3.1 were connected to real emission from composting OFMSW. The biofilter BF2.1 purified the emission directly, whereas BF3.1 purified similar discharge after the intermediate biofilter of the 1st stage of purification (BF0.0). The BF1.0 was left connected to purification of the model mix as a control. The effectiveness of biofiltration of hard-to-remove terpenes was evaluated by gas chromatography of samples taken at the inlet and outlet of biofilters. The average efficiency of removing terpenes from real emissions by BF2.1 was 93.1 % (CT = 5.5 s). The total efficiency of removing terpenes by (BF0.0 + BF3.1) complex was 93.2 % (total CT = 7.4 s). A study of the microbiota of inoculated biofilters after 60 and 90 days of purification the real emission by cultivation from dilutions, identification by the 16S rRNA gene and fingerprinting showed that in BF2.1 and BF3.1 <em>Rhodococcus erythropolis</em> CA1 and <em>Rhodococcus pyridinivorans</em> CA3 were preserved among living cells at a level of 6.5–12.4 %, and genetically fully corresponded to the original cultures.
