However, large-scale deployment remains limited due to its poor investment attractiveness. Traditional Techno-Economic Assessments (TEA), even when accounting for carbon credits revenue, show that BECCS systems are not financially competitive with conventional or renewable energy sources. This study introduces a Techno-Socio-Economic Assessment (TSEA) framework that integrates overlooked societal benefits, such as indirect emission displacement and job creation, by monetising them through the social cost of carbon (SC) and the opportunity cost of labour. A case study evaluates a wheat-straw-fuelled combined heat and power BECCS facility operating under three strategies: electricity and heat cogeneration, carbon credit maximization, and electricity maximization. Conventional TEA results show negative profitability (NPV = −$460 million) and reveal that carbon credit prices must exceed $240/tCO₂ for the levelized cost of electricity to reach parity with renewable energies. Under the TSEA framework, all configurations become profitable with the electricity-maximizing mode reaching an NPV of $2.28 billion. Sensitivity analysis highlights profitability's strong dependence on the assumed social cost of carbon, underscoring the uncertainty and policy sensitivity of BECCS economics. These findings underscore the need to recognize and monetise BECCS's full societal value. Future policies must determine who bears the cost of carbon damages and must establish mechanisms to ensure stakeholders are fairly compensated for the broader social benefits delivered by BECCS, thus fostering investment and enabling real-world deployment of this essential technology.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 255-273"},"PeriodicalIF":9.6,"publicationDate":"2025-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144932824","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":"2025-08-25","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}

This study examines the potential of an increased use of biobased materials in the Swiss residential building stock to mitigate emissions while increasing biogenic carbon storage. Using a Python-based building stock model, the study evaluates the effectiveness of increasing the share of biobased materials in both renovations and new constructions under different scenarios compared to climate goals. Results indicate that renovations will become the dominant driver of building stock emissions and biogenic carbon storage potential by 2050. While new construction activities will decline due to demographic trends, renovations will contribute nearly four times more to GHG emissions than new buildings. Nevertheless, new constructions are more effective at storing biogenic carbon, achieving a biogenic-to-emissions ratio of 300 % by 2050, compared to 176 % for renovations. By mid-century, the yearly biogenic carbon storage in buildings could reach 2.5 Mt. CO₂, approaching a balance with yearly GHG embodied emissions. However, even in the most optimistic scenario, increasing biobased material use alone reduces cumulative emissions by only 5–8 % compared to business as usual, underscoring the need for additional emission reduction strategies, including decarbonizing material production and reducing construction activities. The long-term analysis reveals that biogenic carbon storage potential is constrained by demolition rates (assuming full re-emission at the end of life), with a higher demolition rate accelerating carbon turnover and limiting storage capacity. A cumulative maximum biogenic carbon stock of 300–400 Mt. CO₂ is projected in the long-term, surpassing Switzerland's expected cumulative net emissions removals by 2050 by 6 times. This study highlights the built environment's potential as a long-term carbon reservoir and emphasizes the necessity of targeted renovation strategies, regulatory policies, and material production improvements to achieve climate goals effectively.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 229-240"},"PeriodicalIF":9.6,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144906926","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}

However, there are other crucial sustainability aspects including animal welfare and antibiotic use that sustainability assessments usually neglect due to methodological challenges and lack of available data. This study contributes to the improvement of sustainability assessments of food systems by advancing methods to include animal welfare and antibiotic use. The proposed animal welfare indices reflect the number of animals affected per kilogram of animal product, the animals' cognitive ability to experience negative effects, and the quality of the production system, including disease frequency and space limitations. The proposed antibiotic use indicator acts as a proxy for the risk of bacteria developing resistance to antibiotics that threatens health of humans and animals. It was developed based on national sales data, adjusted for species-specific differences. The animal welfare indices and the antibiotic use indicator were applied to a range of animal products commonly consumed in a set of European countries, revealing substantial variations in animal welfare loss and antibiotic use across species and production systems. For example, rabbit and chicken production showed high welfare loss per kilogram of meat due to the number of animals affected and the relatively poor conditions in intensive livestock systems. Meat from cattle and wild-caught species had lower welfare loss (<em>i.e.</em> favourable) per kilogram, attributed to the larger body mass of these animals and less suffering in production. The methodologies developed here offer a much needed tool for evaluating trade-offs between animal welfare, antibiotic use, and environmental sustainability in food production.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 288-304"},"PeriodicalIF":9.6,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144988177","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 performance of the enhanced system is compared to that of a reference system currently available on the market, under two scenarios: an overnight charging scenario and a fast-charging scenario. An additional scenario is modeled to reflect a limit on the number of fast charges per month to avoid battery replacement. While most existing studies that include battery degradation look at fast-charging effects, they often do not define scenarios based on individual user charging choices and therefore, potential switch between fast and slow charging. In this study, the functional unit is 1 km driven, and the need for battery replacement is calculated using results from ageing tests at the cell level. A sensitivity analysis is also conducted to evaluate the influence of a more decarbonized electricity mix. In the overnight charging scenario, for Ecotoxicity Freshwater, the reference system performs better. Under fast-charging scenario, the improved system outperforms the other across all impact categories. With a decarbonized electricity mix, the reference system performs better across more categories in the overnight charging scenario.
