However, few studies have examined the environmental impacts of apples from production to consumption in China concerning apple losses. Adopting reasonable initiatives in the apple industry from a whole life-cycle perspective can guide sustainable decision-making and support the formulation of policies for achieving carbon neutrality. This study utilized the ReCiPe2016 methodology because it covers a broad spectrum of possible environmental impacts. The aim of the paper was to conduct a comprehensive life cycle assessment of the environmental impacts of apples from production to consumption in China and the associated apple losses along the supply chain. The results showed that producing 1 kg of apples produced the global warming potential of 0.842 kg CO<sub>2</sub>-eq. Nitrogen fertilizer was the most critical environmental hotspot in the apple production phase and contributed more than 60 % in 11 of the 18 environmental impact categories. The environmental impacts in the apple consumption phase generally increased with transport distance. However, short-distance air transport (domestic market) had a higher impact than long-distance truck transport (international market). Among the five consumption scenarios in the domestic market, packaging had a higher environmental impact (1.767-17.926 mPt), exceeding transportation (0.729-14.949 mPt); conversely, in the international market, packaging (10.968 mPt) had a lower impact than transportation (12.181 mPt). Additionally, the study found that more complex sales models resulted in higher apple loss rates, requiring more adequate apple production to meet demand and thereby increasing environmental pollutant emissions. China can take measures such as reducing nitrogen fertilizer usage, designing sustainable packaging, discouraging air transportation, and concerning apple losses to address these challenges. These actions are essential for improving the environmental performance of the apple supply chain in China. Therefore, there is an urgent need to make some recommendations for different stakeholders in the whole life cycle, from production to consumption, to achieve sustainable development. Our work can contribute to offering a blueprint for unlocking unknown knowledge for the apple industry, ultimately catalyzing the realization of sustainable production and consumption in apple systems.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"55 ","pages":"Pages 100-116"},"PeriodicalIF":10.9,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445251","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 impacts embodied in Africa's trade with the rest of the world exceed those related to intra-African trade. African regions exhibit notably higher impact intensities than importing regions.

This study introduces a novel approach integrating life cycle assessment (LCA) with ecodesign to optimize both environmental performance and product effectiveness. The approach was validated through a case study of a large Brazilian chemical industry producing sanitizers. A degreaser floor cleaner was selected for cradle-to-grave assessment, considering raw materials, manufacturing, transport, use, and end-of-life stages. While previous research has focused on LCA and ecodesign separately, this work combines the two to address these dual objectives. Environmental performance was evaluated using a single indicator encompassing and weighing five impact categories: Primary Energy Demand, Water Consumption, Global Warming Potential, Ozone Formation Potential, and Eutrophication. Ecodesign principles guided the redesign of the cleaning product, and its effectiveness was assessed through use tests, for the proposal of 8 improvement scenarios. After redesigning with three optimization strategies (formula, dilution rate, and use method), the solutions led up to 72 % environmental impact reduction. Five of the scenarios also improved product effectiveness, i.e. cleansing. A matrix integrating both environmental and effectiveness scores was developed to select the optimal solutions. This approach could be extended to other industries to support decision-makers in the stages of product development, manufacturing, use and end-of-life, by simultaneously enhancing sustainability and effectiveness.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"55 ","pages":"Pages 76-89"},"PeriodicalIF":10.9,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419233","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}

Notably, the extensive use of steam in silk reeling, urea in mulberry cultivation, and electricity in silkworm farming substantially contributed to both economic and environmental burdens.

The AEE model was applied in Heilongjiang Province of China, to investigate how stakeholder decisions affect CRB's GHG reduction potential and government subsidies. Scenario analyses explore the effects of grain markets, subsidies, and collection distance on environmental and economic outcomes. The findings indicate that more farmers are willing to adopt crop residues collection than those currently practicing it, primarily due to logistical constraints. Key factors influencing adoption include farming income, age, farm size and crop types. CRB contributed to 70.6 % of overall GHG reductions with only 41.6 % of the subsidy, demonstrating higher mitigation efficiency. In conclusion, the government must address the deficiency in crop residues logistics to promote CRB development. Additionally, agricultural policies play a crucial role in ensuring CRB feedstock availability by guiding crop types selection.

However, a dilemma arises when different companies in the same industrial symbiosis network desire to claim for themselves the benefits of such symbiosis and of the upcycling of materials. This study investigates how this upcycling dilemma can be solved, and which solution is obtained following different guidelines for Life Cycle Assessment, namely the Greenhouse Gas Protocol, the ISO standards, and the Product Environmental Footprint. Firstly, a qualitative assessment of the three guidelines is performed to evaluate their normative and empirical elements and their potential to drive change. Secondly, a quantitative assessment is performed by modelling three real-world cases according to each guideline. In each case a residual material from a “supplier” company is upcycled into a new product by a “user” company. Results show that the choice of guideline has a large impact on the results and the incentive created to enter the industrial symbiosis network. The Greenhouse Gas Protocol and the Product Environmental Footprint have several normative elements. Although simple to apply in theory, they leave space for interpretation and ambiguity and tend favour the user company. The ISO standards have empirical elements leading to case-dependent results and requiring a thorough understanding of the system under study to be effectively applied. All guidelines show an improvement when the assessment is performed at system level instead of focusing on one or the other company in isolation, even though such improvement is small in magnitude. The conclusion is that the idea of “sharing” environmental savings is unsound, as upcycling is only obtained in a joint effort, and the recommendation is to evaluate upcycling systemically.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"54 ","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143158705","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}
