Accurate and transparent Life Cycle Assessment (LCA) datasets are essential for reliable sustainability evaluations, particularly in the complex and varied textile industry. Historically, the ecoinvent database has been a foundational source for LCA studies in the textile sector. This paper critically examines the limitations of the ecoinvent v3.7 dataset, which is widely used in academic research, industry tools, and policymaking. While newer versions, such as v3.11, released in 2024, have addressed many issues, including enhanced geographical representation and updated emission profiles for chemicals, this study emphasises the historical implications of earlier data versions. By comparing the cradle-to-gate Global Warming Potential (GWP) of wool and polyester jumpers, this research reveals how aggregated and outdated data underestimated the polyester’s environmental impact while overestimating that of wool. These discrepancies have shaped fibre certification, eco-labelling, and consumer perceptions for years. Understanding the legacy of these datasets is vital for re-evaluating past LCA-based decisions and guiding future assessments toward greater regional relevance and transparency. Full article

Background: Sustainability is a critical concern in transportation, notably in light of governmental initiatives such as cap-and-trade systems and eco-label regulations aimed at reducing emissions. In this context, collaborative approaches among carriers, which involve the exchange of shipment requests, are increasingly recognized as effective strategies to enhance efficiency and reduce environmental impact. Methods: This research proposes a novel collaborative planning model for multimodal transport designed to minimize the total costs associated with freight movements, including both transportation and $C{O}_2$ emissions costs. Transshipments of freight between vehicles are modeled in the proposed formulation, promoting carrier coalitions. This study incorporated eco-labels, representing different emission ranges, to capture shipper sustainability preferences and integrated authority-imposed low-emission zones as constraints. A bi-objective approach was adopted, combining transportation and emission costs through a weighted sum method. Results: A case study on the Naples Bypass network (Italy) is presented, highlighting the model’s applicability in a real-world setting and demonstrating the effectiveness of collaborative transport planning. In addition, the model quantified the benefits of collaboration under low-emission zone (LEZ) constraints, showing notable reductions in both total costs and emissions. Conclusions: Overall, the proposed approach offers a valuable decision support tool for both carriers and policymakers, enabling sustainable freight transportation planning. Full article

This study examined the diverse factors influencing green consumption behavior among Chinese consumers through a comprehensive, data-driven approach that integrated multiple machine learning models, including Gaussian naïve Bayes, K-nearest neighbor, multilayer perceptron, and XGBoost models. By analyzing emotional, product-related, cultural, social, and personal dimensions, this research identified key determinants that shape consumer engagement in sustainable consumption. Unlike conventional studies that rely on linear models or survey-based analyses, this study leveraged machine learning to uncover complex, nonlinear interactions between these factors. The findings reveal that emotional drivers, particularly guilt and pride, play a pivotal role in green consumption decisions, while cultural and product-related factors also exhibit significant influence. This study contributes methodologically by employing a multidimensional, multilevel analytical framework, enhancing the robustness of the findings. Furthermore, the results underscore the importance of policy and marketing strategies that effectively target emotional and social influences to cultivate a sustainable consumer culture. These insights provide actionable recommendations for policymakers and businesses seeking to promote green consumption and advance global sustainability efforts. Full article

Background/Objectives: The effectiveness of eco-labels in encouraging more sustainable food choices varies across studies. We investigate whether consumers’ characteristics may explain this heterogeneity in the context of carbon footprint labeling by studying the moderating role of sociodemographic factors (age, gender, ethnicity, occupation), socioeconomic status (education and subjective socioeconomic position), place of residence (rural to urban), and political ideology. Methods: We manipulated the proportion of carbon-labeled products in two incentive-compatible and pre-registered choice experiments. The first (n = 715) asked consumers to shop for instant meal products in an online grocery store containing a food category’s complete product assortment. The second (n = 1233) forced consumers to make tradeoffs between product preferences and carbon emissions in two consecutive food choices for cut fruit products, one without and another with carbon labels. To capture potential lasting effects, we collected purchase intention data from the same respondents several months after the labeling exposure in both studies. Results: Across both studies, increasing the proportion of products with a carbon label led liberals and centrists to choose lower-emission foods but had minimal or no impact on conservatives (although it never backfired). None of the other individual characteristics moderated the effects of labeling after controlling for political ideology. However, a young age, a low subjective socioeconomic position, and an urban residence indirectly improved responsiveness to labeling by predicting a more liberal political ideology. The labeling effects observed for liberals persisted for four months but not longer. Conclusions: These findings demonstrate the critical moderating role of political ideology and provide actionable insights to improve the targeting and design of sustainability interventions.

Fish sustainability has become an ever more important issue in recent years, as increases in consumption are leading to overfishing practices, resulting in the depletion of the seas and environmental damage. Therefore, fish companies have been adhering to sustainability programs, although these sustainable practices are not well valued and thus well known by end consumers. Therefore, this study aimed to assess the impact of sustainability label information on the hedonic perception of a consumer group regarding two fish species threatened by overfishing: European anchovy (Engraulis encrasicolus) and Bluefin tuna (Thunnus thynnus). The approach used was a blind–expected–informed evaluation. The results showed a positive perception of the species with the sustainability label by recording higher informed hedonic scores than blind ones. Thus, in conclusion, fish sustainability positively influenced the consumers, increasing their liking scores from the blind to the informed session. This study can expand previous knowledge on environmental sustainability, especially fisheries sustainability, and understand the relationships between sustainability eco-labels and consumer behaviour.

Sustainable food consumption is crucial for mitigating environmental degradation and promoting social and economic well-being. Despite growing interest in sustainability, significant challenges persist in consumer adoption and market integration. This study conducted a systematic literature review (SLR) to explore the key drivers, obstacles, technological innovations, and corporate strategies shaping sustainable food consumption. The review synthesizes findings from peer-reviewed research published between 2015 and 2024, analyzing patterns across economic, geographic, and sociobehavioral contexts. Health concerns and environmental awareness are primary drivers, complemented by ethical values, taste perception, and social norms. However, economic constraints, limited product availability, lack of awareness, and behavioral inertia hinder its widespread adoption. Technological advancements, including digital platforms, AI-driven food safety solutions, blockchain for traceability, and alternative proteins, present opportunities to address these challenges. Corporate initiatives such as corporate social responsibility (CSR), fair-trade programs, and eco-labeling enhance consumer trust and accessibility. This study highlights key research gaps, particularly regarding cross-cultural variations in sustainable consumption patterns, long-term behavioral shifts, and the role of digital interventions in influencing consumer decision-making. A multi-stakeholder approach involving academia, businesses, and policymakers is crucial for developing strategies to facilitate the transition toward a sustainable and resilient food system.

Over the past few decades, many environmental labels and schemes have been established at different levels to verify the degree to which businesses are operating in an environmentally sustainable manner and to inform tourist choices. These voluntary tools are used by tourist accommodation services to guarantee quality and conformity to high environmental and sometimes broader performance criteria, drive sustainability awareness and act as a marketing tool. According to the EU’s “Transition Pathway for Tourism” and “European Agenda for Tourism 2030”, environmental labels and schemes can play a role in driving the green transition and strengthening the contribution of tourism to the European Green Deal. This article summarises the main findings from an online survey conducted among global entities managing environmental labels and schemes for tourist accommodation services. The aim of this study is to provide a first characterisation at the European Union level. The results show that, in addition to EU tools such as the EU Ecolabel and the EU Eco-Management and Audit Scheme, a diverse range of other labels and schemes is available on the market, but further harmonisation, clarity, and transparency are required to enhance the uptake and effectiveness of these tools for the accommodation sector.

In this study, several professional cleaning products were analyzed for their impact on local air and sewage contamination. The products were first analyzed for their content of potentially harmful ingredients, their biodegradability, and the potential for the mobilization of hazardous substances from the floorings that were cleaned. The contribution of the cleaning products to sewage pollution with environmentally hazardous substances was studied at full scale. All commercially available cleaning products studied were declared to be environmentally friendly (labeled with the EU Ecolabel). However, despite being labeled as “green” products, between 16 and 24 volatile harmful ingredients were identified. An optimized experimental product, produced completely from natural raw materials, also contained several harmful substances originating from the herbal raw materials themselves. During the field study, we identified a range of trace substances in the sewage. Eight of these substances (e.g., p-cymene, butanone, eucalyptol) significantly originated from the cleaning products. Several others may have originated from the cleaning products, but other sources were also possible. The flooring materials that were cleaned contained several harmful substances themselves. The release of some substances (e.g., toluene) into the sewage significantly increased during the cleaning process. Full article

This study investigates the effects of information disclosure on consumer acceptance of organic and conventional rice, focusing on sensory experiences and repurchase intentions. Two randomized controlled trials were conducted with 211 university staff members to examine how farming practice information, package design, and producer information influence taste perception and willingness to eat rice again. In the first trial, disclosure of organic farming information significantly improved both taste perception and willingness to eat organic rice again. The proportion of participants preferring organic rice taste increased from 31.8% to 44.8%, while willingness to eat organic rice again rose from 16.4% to 34.4% with information disclosure. The second trial, focusing on conventional rice, revealed that while package design and producer information did not significantly affect taste perception, they positively influenced repurchase intentions. Willingness to eat rice in a designed package again increased from 17.3% to 29.4% when producer information was disclosed. Across both trials, a strong relationship between taste evaluation and willingness to eat again was observed. Individual attributes, such as being particular about food, showed complex relationships with rice evaluation. Notably, environmental awareness, despite being prevalent among respondents, had limited effect on organic rice evaluation. These findings have important implications for organic rice marketing strategies and the promotion of sustainable agricultural practices. They suggest that providing clear information about organic farming practices could enhance consumer acceptance and potentially increase market share for organic rice. For conventional rice producers, results highlight the importance of package design and producer information in influencing repurchase intentions. Full article

Ecotourism represents a modern form of tourism that accepts the principles of sustainable development and the adequacy of the conditions of tourist destinations. The environmental awareness of all parties participating in tourism, objects, and subjects of tourism determines the development of ecotourism. Ecohotels, or “green hotels”, as an integral part of ecotourism, represent tourist accommodation facilities that have the “The Flower” certificate, their business activities minimize the impact on environmental quality. The management of ecohotels therefore implements programs and measures determining sustainable competitiveness at the local, regional, and supra-regional levels in the business in interaction with reducing the carbon footprint, water consumption, energy consumption, and waste production. They also support the use of recyclable materials and bio-products and the introduction of environmental management respecting the principles of green management in all areas of the tourism business. The competitiveness of ecohotels is in interaction with the willingness of tourists to use their pro-environmental services. The presented study is focused on the willingness of tourists to use the services of ecohotels, with an emphasis on identifying an effective strategy for supporting the development of ecotourism in the Slovak Republic. The study concentrates on the willingness of tourists to use ecohotels as part of their tourist activities based on a questionnaire survey. The study identifies the factors of strengths and weaknesses as well as the opportunities and threats of the use of ecohotels by tourists in supporting the development of ecotourism. Through the exact quantification of the weights of individual factors in terms of Saaty’s matrix and a SWOT analysis, an effective strategy for the use of ecohotels in supporting the development of ecotourism is defined. In recent years, the stimulation and use of tourists’ interest in environmental quality, with an emphasis on reducing negative impacts on the environment, has resonated; thus, a model of effective marketing strategy is presented.

In recent years, consumer concern about the origin, process and environmental impact of food and beverages has increased significantly, due to sustainability and food safety issues. However, studies of consumers’ willingness to pay for these types of attributes in traditional agave distillates are scarce. In this article, a discrete choice experiment was carried out on a sample of Mexican Raicilla consumers (n = 300) to estimate their willingness to pay for attributes such as ecolabels, protections of origin and the production process; the analysis was performed using a mixed logit model. The results showed that consumers are willing to pay a higher price for a Raicilla that contains on the label the region of origin, the production process (ancestral or artisanal), that has some legal-economic protection, such as geographical indication or designation of origin, and certifications in water management and organic production. The methodology of discrete choice experiments made it possible to jointly evaluate the extrinsic attributes in the willingness to pay for a traditional agave distillate, allowing its influence on the decision to purchase to be determined.

The increasing awareness of environmental, social and cultural issues has highlighted the concept of sustainable certification. The aim of this study is to understand the main drivers and constraints for companies to join certification schemes and compare possible changes between the years 2021 and 2024 among tourism companies. A total of 417 online questionnaires were collected, and a comparative study was conducted. The findings show that the drivers for implementing certification schemes are improving the company’s image and customer-based brand equity, strengthening competitiveness, achieving eco-efficiency, cost reduction, and competitive advantage. On the side of the obstacles that discourage the adoption of certification schemes, there are difficulties in meeting the criteria of the certifications, adapting working methods, higher costs, and lower price competitiveness. The results also show that there was a significant increase in the number of certified companies and that women and young entrepreneurs are more sensitive to the implementation of good practices. It has been concluded that although there is greater demand and interest in implementing good tourism practices, people who know less about certification schemes and companies that are not certified have a weaker opinion regarding this topic.

The rise of sun and beach tourism has led to concerns about the environmental impact of sunscreens on marine ecosystems. Although the contaminants included in sunscreens are being studied from various perspectives, there are still gaps in the understanding of beachgoers’ habits and sunscreen use, and their awareness of the problems these products can cause. But do we even know how much sunscreen ends up in the ocean when beachgoers apply it? To estimate the amount of sunscreen entering coastal waters during a summer season, a survey (n = 429) was conducted at two urban beaches in southern Spain (La Caleta and La Bajadilla). It was estimated that 76.3 to 109.3 mL of sunscreen per beachgoer enters the water during the season. For this estimation, it was crucial that we the analyze beachgoers’ behavior statistically. Additionally, our study calculated their willingness to pay (WTP) for eco-labeled sunscreen alternatives. The results showed significant differences between the two sites, with La Bajadilla reporting higher sunscreen usage (11.9 mL vs. 7.9 mL per application) and a greater WTP for eco-labeled sunscreen (€14.2 vs. €11.5). These findings highlight the need for more field studies to better understand the input of sunscreen into coastal waters, which is closely linked to beach use and its social factors. This approach, which considers specific sunscreen input and characterizes beachgoers’ habits, behaviors, and preferences for alternatives, provides valuable insights for decision-makers and may guide future research on the potential impact of sunscreens on marine ecosystems using behavioral data as well as alternative approaches to solving the problem.

The environmental impact of the fashion and textile industry (FTI) is measured and communicated through several interrelated methods, tools and platforms. In this paper, scholarly and grey literature have informed the mapping of the sector’s environmental impact assessment (EIA) landscape to identify key gaps and challenges in effectively quantifying and communicating environmental product performance. These preliminary insights informed the design of multiple focus group discussions where the on-the-ground challenges of EIA implementation were discussed with 85 FTI stakeholders, including industry professionals, academics, non-governmental organisations and local government. Key findings highlight the need for further refinement and harmonisation of assessment methodologies and approaches such as Life Cycle Analysis (LCA) to consider a wider range of impact categories to increase the comparability of results. Similarly, the communication asymmetries linked to a profusion of eco-labelling and ranking systems necessitates the development of better tools to communicate the environmental performance for the sector. Furthermore, as all EIA methods require the movement of data between various actors, there is a need for improvement and innovation in data-gathering and management systems to ensure greater quality and reliability.
