The proliferation of VSS in global agricultural trade has increased the need for value chain participants, particularly smallholders in developing countries, to comply with multiple sustainability measures, necessitating an assessment of their economic implications. This study investigates the economic impact of double Fairtrade and Organic certifications on smallholder coffee farmers in Ethiopia, a major coffee-producing country where these certifications are widely adopted. The analysis is based on survey data collected from certified and noncertified smallholder coffee producers using a multistage random sampling approach. To ensure the robustness of the findings, the study employs Propensity Score Matching (PSM), Endogenous Treatment Regression (ETR), and Ordinary Least Squares (OLS) methods. The results across all estimation techniques consistently reveal that certified farmers experience significant increases in coffee yield, price, and dividends from coffee sales, despite an associated rise in total production costs. By incorporating cooperative performance as a control variable to account for potential confounding effects of cooperative characteristics, the estimated treatment effects were slightly moderated; however, the positive impact of VSS certification remained statistically significant. These findings suggest that VSS certifications contribute to improving the livelihoods of smallholder coffee farmers, although challenges persist in optimizing the cost-effectiveness of compliance. Furthermore, the study underscores the importance of considering local contexts and institutional heterogeneity to fully understand the broader impact of VSS and maximize their benefits for smallholder coffee producers.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"55 ","pages":"Pages 268-284"},"PeriodicalIF":10.9,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

As global efforts to mitigate CO₂ emissions intensify, DACCS is increasingly viewed as a promising solution, yet its broader environmental implications require careful consideration. The review synthesizes findings from various LCA studies, revealing substantial variability in life cycle efficiency and environmental impacts across different DACCS systems. Solid sorbent technologies demonstrate average net greenhouse gas reductions of 640 kg CO₂-eq/t CO₂, while liquid sorbent systems achieve reductions of about 560 kg CO₂-eq/t CO₂, with system carbon efficiencies ranging between 56 % and 64 %, influenced by operational conditions and regional factors. Beyond climate impacts, DACCS systems exhibit significant resource demands: water consumption ranges from 1 to 12 tons per ton of CO₂ captured, and land use spans 85–4450 km² based on system configuration and renewable energy requirements. For gigaton-scale facilities, significant environmental trade-offs emerge, including substantial particulate matter emissions (170–180 kt annually) and varying impacts on marine eutrophication (up to 90 % higher for amine-based systems compared to hydroxide-based alternatives). Low-temperature DAC systems exhibit higher human toxicity and ecotoxicity impacts due to increased electricity demands, while metal resource depletion varies significantly based on system design and energy sources. This study highlights the critical need for standardized LCAs and transparent reporting practices to enable consistent comparisons between technologies. Based on the analysis, the review provides recommendations for optimizing system design and deployment strategies to minimize environmental trade-offs while maximizing carbon removal potential. These insights support efforts to achieve carbon neutrality by 2050 in alignment with Intergovernmental Panel on Climate Change (IPCC) targets.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"55 ","pages":"Pages 217-241"},"PeriodicalIF":10.9,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China, as the leading global producer of traction batteries, faces significant challenges with the social risks associated with battery technologies, particularly Nickel Cobalt Manganese batteries (LiNi_xCo_yMn_zO₂), which require substantial amounts of critical raw materials. Previous studies have investigated social risks using supply chain data with assumptions, neglecting the actual supply chain in China. Additionally, they have overlooked the upstream indirect impacts. To address these gaps, this study employs social life cycle assessment to evaluate the potential social risks along the global raw material supply chain for different NCM batteries in China. It identifies “Governance,” especially corruption, as a significant social impact along the supply chain, with aluminum from Guinea being the major hotspot. Recycling can mitigate nearly 37 % of these risks despite the involvement of chemical reagents. NCM 811 can reduce total social risks by over 40 % compared to NCM 111 and decrease China's social risk impact on other countries and regions by 46 %, primarily due to its higher energy density. Notably, 12 % of the total impacts are upstream indirect impacts, emphasizing the need for a comprehensive supply chain analysis. In addition, potential social risks are allocated to Sustainable Development Goals (SDGs) to explore their impact on sustainability.

However, this results in trade-offs as some aspects of higher welfare systems reduce production efficiency and thus increase greenhouse gas emissions. These trade-offs have however rarely been studied. This study aims to further the understanding by comparing the impact of reducing stocking density and switching to slower-growing broiler hybrids on broiler welfare and greenhouse gas emissions. Impacts on broiler welfare were determined by synthesizing quantitative welfare indicators from recent studies which assessed the welfare of broilers at different stocking densities and/or growth rates. The impact on greenhouse gas emissions from introducing these changes were modelled for chicken meat produced in Swedish broiler systems. Then, the magnitude of trade-offs associated with a reduced stocking density and/or use of slower-growing broilers were determined based on how these impacted broiler welfare and greenhouse gas emissions. The largest trade-offs were found when using slower-growing hybrids, since while this increased broiler welfare considerably, it also increased greenhouse gas emissions. The magnitude of the trade-offs was largely dependent on the growth rate of the slower-growing hybrid. Slower growth rates increased feed intake, and hence greenhouse gas emissions, but increased greenhouse gas emissions were partly offset by reduced emissions from parent animals. Trade-offs were smaller when reducing the stocking density in broiler houses, due to a moderate improvement of welfare but only a slight impact on greenhouse gas emissions. This study highlights the existing tensions between improving broiler welfare and minimizing greenhouse gas emissions and the need for tools to navigate these trade-offs. However, as greenhouse gas emissions from broiler production remain considerably lower than those of other livestock when higher welfare methods are used, we question whether minimizing greenhouse gas emissions should be a priority when conflicting with improving broiler and breeder welfare.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"55 ","pages":"Pages 203-216"},"PeriodicalIF":10.9,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents the results from a life-cycle assessment for energy, water, and wastewater systems in a Swedish, urban neighbourhood where local, more self-sufficient and circular systems, including solar power, rainwater harvesting, and resource recovery from wastewater, were compared to conventional, centralized systems. The analysis revealed that the cases with local systems had a lower marine eutrophication and land use impact, but they did not decrease the environmental impact in terms of global warming, mineral resource depletion, and freshwater eutrophication in this site with well developed, efficient conventional systems. There were however differences between the subsystems, such as a lower global warming potential for local wastewater management due to avoided impacts from resource recovery. Local systems also had advantages under certain conditions, such as in neighbourhoods with large infrastructure networks per person and long distances to connect to the existing infrastructure grids. For planners and decision-makers, this study indicates that self-sufficiency is currently rather motivated by other benefits than decreased environmental impact in places with similar conditions to this study. It also highlights that these systems are more worthwhile from an environmental perspective in the above-mentioned conditions or in sites with larger environmental impact from the conventional systems. For producers, some key areas for improvement to decrease the environmental impact include production of photovoltaic modules and batteries for electricity, leakage of refrigerant from heat pumps for the heat supply, production of the storage tank for rainwater collection, production of expanded clay as filter material for the greywater treatment, production of sodium hydroxide for blackwater treatment, and emissions in operation for both greywater and blackwater treatment.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"55 ","pages":"Pages 170-184"},"PeriodicalIF":10.9,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143479226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding circularity indicators, End of Life Indices and the Product Circularity Indicator were considered the most relevant for use due to their coverage of multiple life cycle stages and circularity strategies. However, the results suggest a discrepancy in stakeholders' views regarding the best circular design criteria and the most suitable circularity indicators.
