The dynamic total connectedness results reveal that spillovers are strongly time- and state-dependent, intensifying during crises such as the dot-com bubble, the global financial crisis, and COVID-19, with both adverse and exuberant states amplifying systemic transmission. Net connectedness analysis shows that fiscal policy (FP) and climate policy uncertainty (CPU) are persistent shock transmitters, while REC, the stock market (STM), and economic policy uncertainty (EPU) are mostly receivers, although REC's role shifts toward transmission after 2010, particularly during COVID-19, highlighting its growing systemic importance. Quantile network plots confirm these nonlinear dynamics, with CPU, FP, and REC emerging as dominant transmitters in both lower and upper quantiles, while EPU and STM absorb shocks, reflecting heightened vulnerability in extreme states. Robustness checks using MFQC further demonstrate that fiscal policy shocks are most influential in short-run extremes, EPU dampens renewable adoption in low-frequency stable conditions, and CPU consistently undermines renewables, while industrial production (INDP) supports REC in the long run. Overall, the findings highlight that renewable energy remains highly sensitive to policy and macroeconomic shocks, underscoring the need for credible and stable policy frameworks to strengthen resilience and ensure a sustainable clean energy transition.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"395 ","pages":"Article 127730"},"PeriodicalIF":8.4,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335079","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}

In Australia, many of these wetlands are concentrated on private lands, but are in decline due to land clearing for urban development and agriculture. One opportunity to safeguard these ecosystems is through voluntary coastal wetland restoration. However, little is known about landholder's interest in recovering such wetlands. We conducted a survey with coastal landholders across Australia to explore their readiness to restore coastal wetlands, and their motivations and challenges to engage in restoration policy measures such as blue carbon projects on their properties. Using Exploratory Factor Analyses we identified key drivers of landholder readiness, followed by a cluster analysis to segment landholders based on their levels of readiness and shared characteristics. We found that motivations were largely shaped by stewardship and environmental values, including climate change outcomes. Barriers included limited technical knowledge on restoration, financial uncertainty, and concerns about project contracts and regulatory complexity. The cluster analysis revealed three landholder groups: ‘Eco-stewards’, ‘Optimists’, and ‘Reluctant adopters’. Eco-stewards were motivated by legacy and environmental values, showing strong interest in restoration, and blue carbon projects with minimal demand for financial assistance. “Optimists” valued both environmental and economic benefits but are likely to require more technical and administrative support. “Reluctant adopters” prioritised land autonomy and profitability and showed the least interest in adopting blue carbon projects. Our findings highlight that flexible programs with tailored support, and simplified project pathways are important to promote wide scale coastal wetland restoration projects in Australia.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"395 ","pages":"Article 127650"},"PeriodicalIF":8.4,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335081","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 solid residue was subjected to sieving, washing, and oxidation as post-treatments to liberate GFs. The catalytic pyrolysis products were examined using GC/MS, GC/TCD, SEM-EDX, and FTIR. The life cycle assessment (LCA) of this approach was also studied based on ISO 14040/44 standards and compared with the typical pyrolysis of WTB. The results showed the success of the catalytic pyrolysis in converting WTB into oil (13–14.2 wt%), gaseous (10.4–12.8 wt%), and solid residue (74.2–75.4 wt%).

{"title":"From waste to wealth: How sustainable supply chain management shapes the link between waste management and investment efficiency?","authors":"Nouha Ben Arfa ,&nbsp;Kaouther Chebbi ,&nbsp;Aymen Ammari","doi":"10.1016/j.jenvman.2025.127684","DOIUrl":"10.1016/j.jenvman.2025.127684","url":null,"abstract":"<div><div>Despite growing corporate sustainability initiatives, the direct relationship between waste management practices and investment efficiency remains largely unexplored, particularly regarding how sustainable supply chain management moderates this relationship. This study investigates the relationship between waste management and investment efficiency, offering new insights into how sustainable supply chain management affects this relationship. A sample of 1458 firm-year observations from S&amp;P 500 firms was collected from Bloomberg and Refinitiv databases between 2010 and 2023. This study uses instrumental variables quantile regression (IVQR) to address potential concerns of endogeneity. The findings reveal that effective waste management significantly enhances investment efficiency. A 10-percentage point increase in recycling ratio reduces investment inefficiency by 0.73 basis points, while a 10-percentage point increase in total waste increases investment inefficiency by 3.83 basis points. The IVQR results confirm these findings while revealing significant moderating effects of sustainable supply chain management. Specifically, sustainable supply chain practices reduce the negative impact of total waste on investment efficiency, particularly for firms in the 90th percentile of investment inefficiency. Conversely, these practices diminish the positive effects of recycling on investment efficiency for high-inefficiency firms, suggesting that operational complexity arising from concurrent recycling and supply chain management initiatives may impair the effectiveness of capital allocation. These findings suggest that managers should strategically sequence waste reduction and supply chain sustainability initiatives to minimize operational complexity. Meanwhile, regulators should implement differentiated policies, emphasizing waste reduction incentives for high-waste firms and providing tailored recycling support based on each firm's efficiency profile, to optimize investment outcomes.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"395 ","pages":"Article 127684"},"PeriodicalIF":8.4,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335086","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}
