These systems are compared against a bifacial CGMPV system (baseline scenario) and national electricity grid mixes, country-specific combinations of fossil, nuclear, and renewable sources, across north to south of Europe.

The overhead dual-axis system showed the highest impacts (16–29 g CO_2eq/kWh), driven primarily by steel consumption in mounting structures.

Evaluating its environmental impact relies on life cycle assessment (LCA), but differences in methodological choices (e.g., LCIA method), product system characteristics (e.g., geographical scope), and modeling environment (e.g., software) often lead to incomparable results. This study examined how such variations affect LCA results for PLA depolymerization through a two-stage approach, consisting of (i) a comparative assessment of all 9 life cycle inventory (LCI) datasets identified in the literature (from 6 studies up to December 2023), which revealed key inconsistencies such as insufficient process detail and data gaps on additives and catalysts, and (ii) a remodeling-based harmonization of the studies using consistent LCA parameters, addressing often overlooked factors including database choice, geographic location, and life cycle impact assessment (LCIA) method. The harmonized results show that the choice of LCI database significantly affects outcomes, especially regarding substitution products. Geographic differences related to energy mix also have notable impacts, while the LCIA method choice has minimal effect. The harmonized global warming potential (GWP) of PLA depolymerization ranges from −2869 to −1378 kg CO₂-eq per megagram (Mg, 1000 kg) of PLA waste. This remodeling-based harmonization can be applied across different fields to improve the consistency and comparability of LCA studies, enabling assessments that can reflect the actual performance of different product systems. The findings highlight the need for transparency in LCA assumptions; therefore, we provide recommendations to improve the reliability and reproducibility of future studies.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"60 ","pages":"Pages 78-95"},"PeriodicalIF":9.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160088","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 a novel contribution, the GR system was designed using <em>Pereskia aculeata</em>, a resilient, edible, and underutilized plant species, and included the analysis of rainwater retention impacts during the roof's use phase. The methodology was structured in three stages: (1) comparison between CR and GR systems, considering construction and the roof's first year of use; (2) sensitivity analysis of alternative materials for GR components, complemented by uncertainty analysis; and (3) a 30-years projection of use-phase impacts. Primary data were obtained from GR experimental prototypes monitored over one year, including irrigation volumes, plant development, and rainwater retention from 50 rainfall events. Secondary data were modeled using the ecoinvent database and literature sources. In the first stage, GR outperformed CR in 11 of 14 impact categories, with total normalized impacts 13 % lower. In CR, 80 % of impacts were from ceramic tile production, while in GR, polymer components were most impactful, polypropylene accounted for 82 % of Fossil Depletion and polyester for 95 % of Ozone Depletion. Sensitivity analysis showed that substituting the module and filter layers' materials with alternative polymers in GR reduced Marine and Freshwater Ecotoxicity by over 70 %. The optimized GR scenario achieved 71 % lower normalized impacts than CR and performed better in 13 of 14 categories. The 30-years projection reinforced the GR's superior performance over time. In conclusion, GR demonstrated substantial environmental advantages over CR. Additionally, GR adds value through food production, making it a promising strategy for promoting urban agriculture.

Given this, the objective of the present study was to assess the net environmental impact of adopting different nutrition strategies with and without supplementing rumen-protected B vitamins (RPBV, B vitamins that are microencapsulated to bypass rumen degradation in cows and be absorbed in the small intestines) in dairy milk production. Seven representative regional dairy production systems across the United States, Canada, Mexico, Chile, Colombia, Australia, and France were investigated, utilizing a total mixed ration (TMR) feeding program supplemented with 3 g of RPBV. The estimated climate change impact scores for all control production scenarios ranged from 1.08 to 1.65 kg CO₂-eq/kg fat protein-corrected milk (FPCM). However, the impact of climate change per kg of FPCM decreased by 5.6–18.0 % when RPBV was supplemented on top of the TMR feeding program. The highest and lowest climate change impact reductions were observed for the RPBV production scenarios in Mexico and Colombia, where the impacts decreased from 1.65 to 1.36 kg CO₂-eq/FPCM and from 1.49 to 1.41 kg CO₂-eq, respectively. Additionally, the impacts of agricultural land use, water consumption, and acidification, as well as eutrophication potential, were reduced by 3.0–16.3 % (with an average reduction of 7.4 % across all scenarios) when the TMR feeding programs were supplemented with 3 g of RPBV. The observed impact reduction could be attributed to improvements in milk production, which varied across different regions, with milk yields ranging from 3.3 % to 19.4 % above those of the control production scenario. Additionally, there were reductions in enteric methane (up to 2.4 %) and nitrogen emissions (up to 10 %). In dairy cows, RPBV acts as an enzyme co-factor at the cellular level by improving the efficiency of key pathways involved in energy, fat, and protein metabolism, which consequently increases milk yield and feed efficiency. The manufacturing and transportation of RPBV to the seven regional destinations examined in the current study had a minimal impact on the total environmental footprint of dairy production systems. The null hypothesis was rejected, indicating significant differences in results, as the p-value for all impacts and pairs (control and RPBV scenarios per 500 Monte Carlo runs) was less than 0.05, which is considered statistically significant. Overall, supplementation with RPBV constitutes a valuable nutritional strategy to support ongoing efforts and innovations in driving sustainable dairy production.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 339-358"},"PeriodicalIF":9.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010443","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}

With approximately two-thirds of global greenhouse gas emissions linked to household consumption, reducing demand-side emissions through low-carbon lifestyle changes is critical. While major emissions hotspots and high-impact consumption changes are known, a cross-country prospective analysis of their emissions reduction potential has been missing. This study quantifies the avoided greenhouse gas emissions from 47 consumption changes across five diverse European countries. We assess how socioeconomic and technological changes influence emissions reduction potentials by comparing such potentials in a baseline year (2015) with those in 2030 and 2050 under a sustainable development scenario. Our findings highlight that the most effective mitigation options involve reducing conventional vehicle use, decarbonizing household heating, and shifting to predominantly plant-based diets. Though country-specific variation exists, we observed that the emissions reduction potentials of many consumption changes evolve proportionally to technological changes. Behaviors involving direct fossil fuel combustion, such as car travel or fossil-fueled heating, remain largely unabated by technological shifts without lifestyle change, thus increasing in relative mitigation potential. Changes relying on electricity substitution, such as switching to a heat pump, were most dependent on systemic decarbonization. These insights demonstrate which household-level actions consistently offer high emissions mitigation potential and which are more sensitive to broader system changes. Our results provide a clearer understanding of how individual climate change mitigation actions intersect with long-term industrial decarbonization strategies, supporting more targeted policymaking for demand-side climate change mitigation.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 408-421"},"PeriodicalIF":9.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048978","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}

The region-specific reference diet (RRD), a culturally appropriate variant of EAT-Lancet Planetary Health Diet, has been recently proposed for China, but its role in promoting sustainable healthy aging remains unclear. We hypothesize that combining RRD with social determinants can enhance sustainable healthy aging and reduce health disparities. Using 2020 food consumption data from the National Bureau of Statistics of China (NBSC), we estimated provincial RRD adherence and its association with healthy life expectancy (HLE) and Green Development Index (GDI). Based on the data from NBSC, the social return on investment identified five core social determinants, pension coverage, telephone subscriptions, senior care workforce, physician access, and internet use, that significantly reduced the unexplained variance in sustainable healthy aging after adjusting for RRD. Scenario-based simulations were performed by comparing four conditions: (1) 2020 status, (2) 2030 projection, (3) RRD adoption alone, and (4) RRD combined with synergistic social determinants. The integrated strategy based on RRD yielded greater improvements in HLE and GDI compared to the 2020 status and 2030 projection, while also significantly reduced regional and gender disparities compared to all other three conditions. These findings underscore the limitations of dietary interventions in isolation and highlight the potential of a multi-sectoral strategy for advancing equal sustainable healthy aging.
