This work explores selected sustainability food labels in the EU, reviewing sustainability indicators and the underlying life cycle assessment (LCA) methodologies. It addresses methodological approaches, and how they apply LCA with reference to the Product Environmental Footprint (PEF) method recommended by the European Commission. Four labels were identified from a comprehensive product database, focusing on labels applying LCA and quantifying multiple impacts, while an additional one was identified from the current EU panorama. An evaluation framework was developed on the relevant methodological aspects, encompassing governance, transparency, and clarity. Interviews with label developers complemented the analysis, along with a review of criticisms of LCA and PEF for labelling purposes. Four are scoring labels providing graded and colour-coded visuals, while one is still under development. Methodological adaptations to the PEF were common, and non-LCA sustainability assessments accounted for aspects such as farming management, social issues, and biodiversity. Labels varied in transparency, stakeholder involvement, and clarity. Criticisms of LCA include its reductionist approach, data gaps, and lack of robust methodologies for assessing biodiversity. While sustainability labelling is important to guide sustainable choices, labels need to be part of a broader policy mix and should be underpinned by clear goals and robust methodologies. This analysis will help to develop evidence-based policy instruments for sustainable consumption and set the basis for a harmonized labelling system.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100334"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-Density Polyethylene (HDPE)-lined ponds and earthen ponds are widely used, but their comparative environmental performance has not been comprehensively evaluated. This study aimed to quantify and compare the environmental impacts of intensive HDPE-lined and semi-intensive earthen pond shrimp farming systems along India's west coast. A cradle-to-farm-gate Life Cycle Assessment (LCA) was conducted using SimaPro software and the ReCiPe 2016 Midpoint method. Primary data were collected from 20 farms and one hatchery, covering seed production, feed use, and energy consumption. Environmental impacts were assessed across multiple categories, including Global Warming Potential (GWP), Terrestrial Acidification Potential (AC), and Marine Eutrophication Potential (EU). Results showed that HDPE-lined ponds had significantly higher GWP (369.04 vs. 268.06 kg CO₂ eq) and AC (1.20 vs. 0.94 kg SO₂ eq) per tonne of shrimp compared to earthen ponds, but lower EU (0.03 vs. 0.05 kg N eq). Seed production, electricity use, and feed emerged as the primary contributors to environmental impacts. Findings suggest that transitioning from HDPE-lined to earthen pond systems, adopting renewable energy sources such as solar aeration, and replacing fishmeal with plant-based alternatives could substantially improve the sustainability of Indian shrimp aquaculture.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100342"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scenario, measuring circularity is critical for ensuring an effective and efficient transition towards such development. Given its relevance, the scientific community and standard-setting bodies are progressively focusing on identifying appropriate circularity indicators. Accordingly, most existing studies have provided broad overviews of available indicators, systematically reviewing academic and grey literature in the context of the agri-food supply chain. Considering the peculiarities of each supply chain within this sector, it is crucial to identify specific indicators in line with their characteristics, providing a practical guide for companies committed to the circular transition. However, a significant gap in research focused on identifying specific indicators for different agri-food supply chain has emerged. To fill this gap, the present research aims to provide a comprehensive framework to measure circularity within the pasta supply chain, representing an essential sector of the worldwide economy. To achieve this, a structured approach was adopted that integrates a systematic literature review with an assessment of the available standards on circular economy measurement. By implementing a rigorous selection process, a final set of 51 indicators – reclassified according to the analytical framework developed in the study – was identified for each pasta supply chain phase. Results show that most indicators could be transversally applied to the PSC. This multi-indicator framework could represent a helpful tool for the pasta industry to measure, monitor and disclose circularity performance in line with the ISO 59020:2024 standard.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100327"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Football, the world's most popular sport, is a prime example. Yet beneath the surface lies an overlooked environmental cost. As the climate crisis accelerates, the sprawling network of football facilities—stadiums, training grounds, and infrastructure—emerges as a silent contributor to environmental degradation and the transgression of planetary boundaries. Two common types of fields exist: artificial and natural turf. Research on environmental impacts of these turfs remains limited, especially in cold climates. This study presents a life cycle assessment of 1 m² artificial and natural football turfs in Nordic climates, evaluating their environmental impacts such as global warming potential, eutrophication potential and ecotoxicity potential across construction, use, maintenance, and end-of-life phases over operational lifespans of 10, 20 and 30 years. Natural turf exhibited the highest overall environmental impacts over the operational lifespan, e.g. the global warming potential was 30.6 kg CO₂ eq/m² while the artificial turf reached 15.6 kg CO₂ eq/m². During the construction phase, artificial turf generated significant emissions, mainly from material production. In the use phase, natural turf showed the greatest impacts due to diesel consumption and fertilizer application. At the end-of-life stage, artificial turf's sand and infill were reused, while the turf carpet and shock pad were incinerated for energy recovery. However, without recycling, artificial turf would represent the highest environmental burden among the evaluated alternatives. Implementing effective recycling and energy recovery strategies is essential to mitigate its environmental impact. Furthermore, sourcing turf materials locally, combined with substituting conventional maintenance equipment with electric robotic alternatives, can further reduce overall environmental impacts.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100369"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145474204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel methodology was developed to calculate the weighted total grey water footprint (W-TGWF), integrating all discharge outlets by considering dilution effects and identifying the final CP. This study, conducted over four months from October 2022 to January 2023, evaluated TGWF and W-TGWF simultaneously for mixed outlets of treatment processes, Activated Sludge (AS) and Membrane Bioreactor (MBR), operated in parallel to treat wastewater from an industrial park in Isfahan province, central Iran. The mixed influent wastewater at the equalization tank, representing the total inlet GWF, ranged from 1.55 to 2.06 million cubic meters per month (MCM/month). For mixed outlets, W-TGWF consistently yielded lower values than TGWF, showing reductions of 22 %, 13 %, 26 %, and 5 % from October to January. The periodic average W-TGWF was 15,304 m³/month based on NH₄ as the CP. In contrast, TGWF reached 18,909 m³/month, 24 % higher, due to the simultaneous influence of NH₄ and F parameters without definitive CP identification. These findings show that TGWF tends to overestimate environmental stress and obscure pollutant prioritization.

In Climate Change, no decrease was observed because EF 3.1 lacks standardized biogenic carbon accounting, preventing this from being captured. Significant variations were found in Ionizing Radiation, Land Use, Ozone Depletion, and Water Use, both in the FB and BB datasets.
