This study introduces a novel framework for accurately accounting for greenhouse gas (GHG) emissions in the international shipping sector, with a specific focus on sustainable marine fuel and onboard carbon capture systems (OCCS), using methanol as a case study. The framework proposes the integration of a carbon source factor and a carbon fate factor to effectively measure and report GHG emissions from shipping activities. By examining methanol as sustainable marine fuel, alongside the implementation of OCCS, this research aims to demonstrate the significant potential for reducing life cycle GHG emissions. When OCCS was applied to 49 case ships, not only were Carbon Intensity Indicator (CII) ratings D or E removed, but the proportion of ships rated A or B was confirmed to increase noticeably from 10 % to 41 %. The findings highlight the critical role of renewable feedstocks and effective carbon management strategies in decarbonizing the shipping industry. The proposed framework offers valuable insights for ship owners, industry regulators, and policymakers, guiding the transition towards sustainable shipping practices and contributing to the global efforts against climate change. This study underscores the importance of developing clear guidelines and standards for GHG emissions accounting in shipping, ensuring consistent and transparent reporting to facilitate effective policy formulation and regulatory compliance.

Significant effort has recently been directed towards promoting remanufacturing as a circular and sustainable approach to production. However, current methods for supporting design for remanufacturing and remanufacturability evaluation often lack integration and practical applicability, failing to address the complex trade-offs and interdependencies inherent in remanufacturing processes. To this purpose, this study addresses the need for methods to evaluate the feasibility of product remanufacturing through proposing a novel integrated method named Economic and ENvironmental Impact Assessment for Sustainability (EENIAS), enabling the assessment of remanufacturability for existing products or those in the detail design stage, by analysing diverse remanufacturing scenarios to quantify their economic and environmental impact. The method is demonstrated and validated through two case studies from different industries: an electrical lighting product and an accumulator used in the oil and gas sector, highlighting its applicability. The results quantify how key remanufacturing scenarios are performing economically and environmentally, offering insights into the products' remanufacturability and the design strengths for applying a Circular Business Model (CBM) based on remanufacturing. The luminaire demonstrated strong potential for remanufacturing, with 23 out of 31 remanufacturing scenarios showing significant financial and/or environmental benefits. In the accumulator case, the analysis revealed the dominance of the accumulator's shell as a significant environmental impact driver, though its financial impact was not equally significant. Consequently, the application of EENIAS provided the critical insight that substantial environmental gains could be achieved if the company designs the product in such a way that the shell does not require replacement after the usage stage. The EENIAS approach supports decisions for remanufacturing and sustainable product design practices, such as Design for Remanufacturing, by providing a detailed assessment of the products' remanufacturability and its potential for CBM application.

Higher education institutions (HEIs) are one of the main actors in promoting transformation towards sustainable development because of their leadership role in educating future leaders, their ability to deal with environmental and socioeconomic problems, and their creation of partnerships with social entities. However, HEIs still need to incorporate sustainability principles into their academic, management, and governance practices, and specific actions are observed without a systemic plan. To understand this scenario, this study sought to identify which sustainable practices and discussions are most debated and implemented on university campuses. Through a systematic literature review, 670 articles were selected and categorized into four dimensions highlighting challenges and solutions. The results highlight that universities focus sustainability mainly on the operational dimension without a systematic improvement approach. Governance does not prioritize sustainability plans; only a few sustainability areas are addressed. Reports and rankings lack reliable indicators and adaptability. Academically, both teachers and students need a better understanding of sustainability, with a focus on interdisciplinary and collaborative teaching methods. Sustainable change should not be limited to developed countries and must encompass the university's mission, educational processes, external relationships, management, and extracurricular activities.

Environmentally sustainable and nutritionally adequate food consumption and production can include a wide selection of foods, which requires detailed information on individual food products to enable sustainable food choices. The aim of this study was to integrate nutritional aspects in the assessment of environmental sustainability of food products against the planetary boundaries. Methodologically, the model was built on the approaches of nutritional Life Cycle Assessment (LCA) and a planetary boundary-based LCA (PB-LCA) that compares environmental impacts against the assigned share of planetary boundaries. Thus, the model can identify food products that provide sufficient nutrition in relation to their environmental impacts, in accordance with the criteria of the planetary health diet. As a result, we developed Nutrient Index-based Sustainable Food Profiling Model (NI-SFPM) and tested its applicability in an assessment of 559 food products across various food categories, considering the impact categories corresponding to the planetary boundaries of climate change, nitrogen cycling, phosphorus cycling, freshwater use, land-system change, and biodiversity loss. The results demonstrated the model's effectiveness in discerning between food products and food categories based on their environmental performance and nutrient composition. The resulted sustainability ranking of different food categories was in accordance with the current understanding of healthy and sustainable diets. By evaluating the sustainability of food products, the NI-SFPM enables informed decision-making for consumers, policymakers, and food industry stakeholders, assisting in optimizing production processes, sourcing sustainable ingredients, and enhancing product formulations. Through these insights, the NI-SFPM has the potential to drive positive changes in food industry by promoting the development and consumption of environmentally and nutritionally sustainable food products.

Recirculation can play an important role minimizing the environmental impact of the textile industry. However, there exist conflicts between recirculation of resources and regulatory strategies for a non-toxic environment. One pathway to remove restricted substances from recirculation is through labelling strategies that inform consumers about the chemical content of products. To date, research on the influence of information about chemical content on consumers' willingness to pay for retail purchases, particular in the clothing sector, is rather limited. Using discrete choice experiments conducted in Denmark, Sweden and the United Kingdom with a sample of 1528 adults, we investigated whether access to information about the chemical content of garments influences consumer willingness to pay across new, recycled and reused clothing. Although access to information about restricted chemicals is enshrined as a right-to-know in the European Union's regulations, the study highlights low awareness of this right: <23 % of respondents in all countries have requested such information. Findings show a strong preference for either instant access to chemical information through a QR code or direct access to information printed directly on a product label. Interestingly, the choice of QR code is preferred over printed product labels. At the same time, information provided in the standard 45-day waiting period is no more preferred than no information at all. Meaningfully, consumers in all contexts are willing to pay a premium for rapid access to information for new and recycled options, but there is uncertainty regarding used options. Our results also show that up to 9 % of the respondents choose according to an elimination-by-aspects strategy, meaning they will avoid purchasing clothes without access to information about chemical content. The results strengthen the need for higher transparency and better exchange of information along textile value chains, however they also emphasize the already high uncertainty faced by circular economy enterprises.

The European bioeconomy offers a sustainable development model, but its successful implementation requires robust sustainability measures. Ensuring sustainability in bio-based value chains requires clearly defined operational characteristics and indicators that comprehensively address key sustainability and circularity aspects. These indicators must align with the European Union (EU) sustainability framework, policies and directives. This study analyzed existing certification schemes and labels (CSLs), benchmarking monitoring systems, and EU policies to identify key sustainability indicators. A grey literature review further supplemented this analysis. Additionally, an alignment study was conducted to assess how EU policies guide the transition towards a bioeconomy. The research identified the key indicators that CSLs should adopt to effectively support the EU sustainability policy framework. A total of 142 sustainability indicators were proposed across environmental (7 areas), social (5), and economic/circularity (4) pillars, along with 60 operational indicators in governance (4 principles), assurance (5), traceability (4), and standard setting (3). The analysis revealed gaps in CSLs and policies, particularly in the economic and circularity pillars, while environmental and social indicators showed better coverage but still need improvements in areas such as land use, air quality, water depletion and consumer feedback. These findings provide valuable insights for certification bodies, industry stakeholders, and policymakers, offering guidance towards the harmonization of CSLs and their alignment with the European bioeconomy policy framework.

Renewable or “green” hydrogen has emerged as a promising option to help mitigate climate change. Given China's abundant solar resources, hydrogen produced using solar energy could be a viable pathway for the country but at present its sustainability is unknown. Therefore, this study evaluates the life cycle environmental and economic sustainability of renewable hydrogen production via polymer electrolyte membrane water electrolysis (PEMWE) using solar photovoltaics (PV) as the main source of energy. Three PV system configurations are considered: a standalone PV (SPV), an off-grid PV with battery storage (BPV) and a grid-connected PV (GPV). The findings reveal the superior environmental performance of SPV. For instance, it has the lowest climate change impact of 4.3–6.5 t CO2 eq./t H2, representing a 14–30 % reduction on BPV and a substantial 84–90 % decrease relative to GPV. SPV also shows notable reductions (4–78 %) across the other impacts in comparison with BPV. While SPV has higher land use and metal depletion (9–170 %) and similar ecotoxicity impacts to GPV, it achieves significant reductions (16–90 %) in the water, soil and air pollution, fossil depletion, freshwater consumption and non-cancer human toxicity (11 out of 18 categories). However, SPV is the second most expensive configuration, with the life cycle costs of 1581–2412 M$ and levelised costs of hydrogen (LCOH) of 3953–6029 $/t. GPV is the best option for costs (1047–1570 M$ and 2741–4048 $/t), while the costs of BPV are around three times as high (4405–5180 M$ and 11,134–12,951 $/t). Looking ahead to 2050, with prospective changes in the grid composition, GPV offers 18–79 % reductions in the climate change, fossil depletion, water consumption, human toxicity and water, soil and air-pollution related impacts, but increases ionising radiation, land use, metal depletion and ecotoxicity by 2–244 % relative to the current grid mix. Currently, SPV outperforms steam methane reforming in four impacts and coal gasification in nine, including climate change, but has a higher LCOH than both conventional processes (1240–2480 $/t). GPV is currently the only option economically competitive with the conventional routes, but it is suboptimal environmentally compared to SPV. This research provides new insights into the selection of optimal configurations for PEMWE hydrogen production in China across different regions and time horizons and will be of interest to technology developers, investors and policy makers.

The demand for natural fibers, including silk, is steadily rising, yet research on transitioning the silk industry from a traditional linear model to a circular economy still needs to grow. This study addresses this gap by outlining areas of interest to support silk companies in applying circular practices to achieve sustainability. To this end, ten semi-structured interviews with silk industry experts were carried out, and a thematic analysis was conducted, integrating findings from the extant literature to enhance the depth and contextualization of the results. Six critical themes emerged: waste utilization, circular approaches, consumer education, technology advancement, traceability and transparency, and governmental regulations. The findings reveal that production waste, such as mulberry branches, silkworm litter, low-grade cocoons, and sericin, can be repurposed into fertilizers, animal feed, cosmetics, and textiles, offering both environmental and economic benefits. Circular practices like designing for product longevity, minimizing chemical usage, reusing silk garments, and promoting recycling are key to achieving resource optimization and waste reduction. Technology advancements, including artificial intelligence and blockchain, enhance efficiency and ensure traceability and transparency, fostering stakeholder trust. Consumer education is also vital for creating awareness regarding sustainable practices. Additionally, government policies play a transformative role by supporting training programs, incentivizing innovation, and driving circularity within the industry. This study proposed a theoretical framework that offers actionable insights to industry practitioners, researchers, and policymakers for embedding circularity throughout the silk industry, contributing to global Sustainable Development Goals (SDGs), particularly responsible consumption and production. Future research should explore barriers to attaining circularity and use mixed methodologies to accelerate the silk industry's transition to a circular economy.

In the realm of sustainable manufacturing and end-of-life management, efficient disassembly processes and their measurement have become increasingly vital, especially in light of the Circular Economy principles, which emphasize efficient resource management. However, traditional product designs often neglect disassembly considerations, leading to challenges in resource recovery and reuse at the product's end-of-life. To overcome the above challenge, this study introduces the Multidimensional Disassembly Index (MDI), a structured framework to evaluate the disassembly efficiency of a product during its early design phase. The proposed approach systematically analyzes independent variables that directly impact the disassembly process and evaluate the disassembly effectiveness based on these independent variables. Through a case study, the paper demonstrates how the proposed methodology supports design improvements for easy disassembly. Using the MDI approach, the effectiveness of disassembly for remanufacturing and recycling was evaluated in a case study on a retractable ballpoint pen's design. The MDI score for remanufacturing is 9.01, reflecting ease of disassembly, while recycling MDI scored 8.74, highlighting design improvement on plunger accessibility and clicker material compatibility. The study concludes that the MDI is a valuable tool for advancing Design for Disassembly (DfD), enabling the development of products optimized for circular lifecycle strategies at earlier design stages.

Nowadays, industries face increasing pressure to enhance their environmental sustainability scores, particularly in reducing carbon footprints. Life Cycle Assessment (LCA) tools are commonly used to evaluate environmental impacts across organizational levels, enabling predictions for potential improvements. But complexity and diversity of factors influencing these assessments make prediction models difficult to build and validate. Machine learning (ML) techniques present viable solutions to these challenges.
This study presents a systematic literature review (SLR) of seventy-eight peer reviewed articles, evaluating the performance of different ML models in Life Cycle Assessments applications. An analytical ranking of these models is provided based on their effectiveness for LCA predictions using the Analytical Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Results indicate that Support Vector Machine (SVM) achieve a score of 0.6412, followed by Extreme Gradient Boosting (XGB) at 0.5811 and Artificial Neural Networks (ANN) at 0.5650, and, positioning them as the most suitable models for LCA studies for prediction application. Random Forest (RF), Decision Trees (DT), and Linear Regression (LR) follow with scores of 0.5353, 0.4776, and 0.4633, respectively, while Adaptive Neuro-Fuzzy Inference System (ANFIS) and Gaussian Process Regression (GPR) rank lowest with scores of 0.4336 and 0.2791. Detailed interpretations and implications of these findings are discussed.
