Decarbonizing the transport sector, a key contributor to climate change, is challenging. While battery electric vehicles offer relative improvements in the use stage, they must be evaluated against absolute sustainability targets, taking into account the entire life cycle. This study develops a simplified life cycle assessment (LCA) model based on parametric modelling for the absolute environmental sustainability assessment of NMC811 battery pack production. Simplified LCA models are constructed through variance decomposition based on first-order Sobol indices.</div><div>The estimated climate change impacts are compared against absolute sustainability targets to determine the probability of achieving them. Climate impacts for the battery pack range from 87.9 kg CO₂-eq/kWh at the 5th percentile to 134.0 kg CO₂-eq/kWh at the 95th percentile, with a mean value of 108.0 kg CO₂-eq/kWh. The mean climate change target value, representing the maximum allowable climate impact, for a 58-kWh battery pack is estimated at 27.25 kg CO₂-eq/kWh. Extending the battery pack's lifetime from 10–15 years to 15–25 years increases the target value to 36.20 kg CO₂-eq/kWh. The use of secondary aluminium in battery production has the highest potential for reducing climate change impact. The results of the local sensitivity analysis indicate that using 100 % secondary aluminium reduces the climate change impact by 22.65 %. This also reduces the impacts in 14 other ReCiPe method midpoint impact categories.

This European framework also requires that consumers be provided with clear and accessible information on their options to repair or replace broken appliances, emphasising the environmental and economic advantages of repair. Focusing on the product category of ‘capsule coffee machines’, this research aims to provide consumers with comprehensive information to support decision-making regarding repair costs and environmental performance. The study's novel approach integrates Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) methodologies, enabling a holistic evaluation of the environmental and economic impacts of repair versus replacement decisions. Additionally, it introduces repairability indices for specific components and presents the findings in a consumer-friendly format, aligned with the European ‘Right to Repair’ initiative. To this end, four capsule coffee machines were selected as a case study. A diagnosis of the current repair landscape was conducted using data from the Open Repair Alliance, which provided information on priority parts, failure rates, failure ages, and repair success rates. Repairability indices for each machine and its priority components were then calculated in accordance with the EN 45554 standard. Finally, replacement and repair scenarios were analysed to assess their environmental and economic performance. The results indicated that prioritising the repair of components with high failure rates and ease of repair offers significant environmental and economic benefits. This transparent information can be provided to consumers, enabling them to decide between repairing or replacing their equipment. In theoretical terms, this framework enhances understanding of integrated sustainability assessments by combining environmental and economic analyses. In practical terms, it provides actionable insights for manufacturers and policymakers to design products for repairability. For society, it empowers consumers to make informed decisions that foster sustainable consumption and production.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"57 ","pages":"Pages 226-245"},"PeriodicalIF":10.9,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222837","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 findings reveal that although these start-ups act as catalysts for change at the niche (micro) level, their broader impact depends on meso-level factors (stakeholder networks) and macro-level conditions (public policies). The adoption of digital technologies and collaboration with actors such as universities, governments, and investors are critical to their scalability.

Climate change (CC) was significantly attributed to human health and ecosystem quality impacts, while the major contributor to resource scarcity impact was fossil resource scarcity (FS). In some scenarios, non-exhaust emissions, particularly from freight trucks, accounted for 40–60 % of the total PMF impacts.

Both operational GHG emissions from energy consumption in buildings and embodied GHG emissions from new constructions, renovations and demolitions are included. The Morris screening analysis and the Sobol global sensitivity analysis are applied to a building stock model that combines dynamic material flow analysis with prospective life cycle assessment. The two sensitivity analysis methods produce different rankings of the most influential parameters, underscoring the need to combine them for a more comprehensive analysis. In addition to energy-related parameters, the average living area per person also emerges as one of the most influential parameters, emphasizing the importance of incorporating efficient use of space into current policies. The study also evaluates the impact of the rate at which each parameter will evolve by 2050. For instance, if GHG reduction measures are implemented slowly, reducing personal heating consumption or changing construction material production will have a greater impact than changing heating systems. However, if heating system upgrades can be quickly implemented, they would have a greater effect than the other two measures.

Finding sustainable protein sources is fundamental to reducing the impact of our food system, but more research is needed to bring novel products into consumers' diet. Mycoprotein is a meat substitute obtained from fungal biomass showing an improved environmental profile and unexplored market potential. In this study, we evaluated the environmental performance of a novel mycoprotein obtained from <em>Yarrowia lipolytica</em> and suggested optimization strategies. From a lab-scale proof of concept, we designed a commercial production plant simulation to retrieve a cradle-to-gate inventory. Mycoprotein and most consumed meats were compared across United States, Europe and Brazil in a cradle-to-grave life cycle assessment, while the planetary boundaries framework added an absolute sustainability perspective. Results show a superior environmental performance of mycoprotein compared to beef in all impact categories except water use, where it shows 40 % increased impact. No significant variation is observed across mycoprotein production locations. Mycoprotein shows significant sensitivity (up to a 2.2-fold increase) to the selected functional units, based on different protein digestibility scores. From an absolute sustainability perspective, completely replacing beef with mycoprotein in an average diet shows the least transgression levels of planetary boundaries, although optimization of the food supply chain is necessary to stay within the limits. The major hotspot is found in the egg white used as binder in the formulated product, suggesting a plant-based substitute. With potato starch as potential replacement, we observe up to a 97 % impact reduction, achieving better performance than beef, pork and chicken meat in all impact categories with the except of climate change, where mycoprotein still shows 33 % higher impacts than chicken.
