Consumption Patterns and Willingness to Pay for Sustainable Aquatic Food in China.

China, as the world's largest producer, trader, and consumer of aquatic foods, lacks comprehensive research on consumption patterns and willingness to pay for sustainable aquatic food. This study addressed this gap through an online survey of 3403 participants across Chinese provinces. A majority of consumers (34.7% of the participants) consume aquatic food twice or more per week, mainly from traditional markets (26%). Most prefer fresh or live products (76%), with 42% seeing no difference between farmed and wild options. Consumption is higher among older, affluent, urban, and coastal residents. Crustaceans, especially shrimp, are frequently consumed species, with growing interest in luxury species like salmon and abalone. Taste and quality emerge as the primary factors motivating consumer choices in aquatic food purchases. Food safety is the primary concern, followed by environmental impact. Notably, 92.4% of participants would pay extra for certified products. Factors influencing a higher willingness to pay include higher income, inland residence, price sensitivity, origin consciousness, and concerns about food safety and the environment. The findings highlight that China's aquatic food industry and consumption can become more sustainable by aligning with consumer preferences for high-quality and diverse aquatic food through both production and import, while also addressing concerns related to food safety and environmental impact. This research provides valuable insights into China's rapidly transforming aquatic food market landscape, offering implications for industry innovation and the promotion of sustainable consumption patterns.

Strengths and weaknesses of food eco-labeling: a review.

Food labeling is increasingly expanding and adding more information to the food package. There is strong evidence about nutrition labeling effectiveness in driving food choice, especially if displayed in the front of package (FoP). Despite the growing attention to nutrition and sustainable diets, few countries have implemented sustainable labels or eco-labels that could address economic, social and/or environmental concerns. Implementing new techniques of eco-labeling emerges as a consumer-focused solution. However, evidence of the effectiveness of eco-labeling in driving consumers' choices is heterogeneous and not univocal. Thus, this review aims to summarize the evidence about the effectiveness of FoP eco-labeling in driving food choice and provide a reference framework of the eco-labeling initiatives relative to food package labeling. This narrative review addresses both the potential benefits as well as the main concerns that arise from the use of eco-labels. Although eco-labeling seems to provide a series of sustainability benefits for producers and consumers, the implementation of such policies should take into consideration potential trade-offs and inter-sectorial coordination to obtain bigger impacts, assuming that a policy itself cannot transform the whole food system. Eco-labeling could be encouraged and implemented within a set of policies shaping sustainable food systems.

Evaluation of Climate-Aware Metrics Tools for Radiology Informatics and Artificial Intelligence: Toward a Potential Radiology Ecolabel.

Radiology is a major contributor to health care's impact on climate change, in part due to its reliance on energy-intensive equipment as well as its growing technological reliance. Delivering modern patient care requires a robust informatics team to move images from the imaging equipment to the workstations and the health care system. Radiology informatics is the field that manages medical imaging IT. This involves the acquisition, storage, retrieval, and use of imaging information in health care to improve access and quality, which includes PACS, cloud services, and artificial intelligence. However, the electricity consumption of computing and the life cycle of various computer components expands the carbon footprint of health care. The authors provide a general framework to understand the environmental impact of clinical radiology informatics, which includes using the international Greenhouse Gas Protocol to draft a definition of scopes of emissions pertinent to radiology informatics, as well as exploring existing tools to measure and account for these emissions. A novel standard ecolabel for radiology informatics tools, such as the Energy Star label for consumer devices or Leadership in Energy and Environmental Design certification for buildings, should be developed to promote awareness and guide radiologists and radiology informatics leaders in making environmentally conscious decisions for their clinical practice. At this critical climate juncture, the radiology community has a unique and pressing obligation to consider our shared environmental responsibility in innovating clinical technology for patient care.

Consumer willingness to pay for shelf life of high-temperature, short-time-pasteurized fluid milk: Implications for smart labeling and food waste reduction.

Food waste in the United States was valued at $285 billion in 2019, representing 70% of all food surplus; dairy and eggs alone represented 15.90% of food surplus. Milk is the fifth most consumed beverage in the United States, and therefore its contribution to food waste has significant economic and environmental ramifications. Smart labels that provide precise spoilage information for fluid milk may help reduce food waste in fluid milk, but it is unclear if consumers will accept or pay for this novel technology. This paper examines consumer preferences for high temperature, short time pasteurized fluid milk shelf life and smart date labels and tests how information about the environmental impact of fluid milk food waste affects consumers' acceptance and willingness to pay. We used a choice-based conjoint study administered in an online survey, along with a between-subject experiment to measure preferences under different information treatments about the environmental impact of food waste. Our results suggest that consumers' valuations of extended shelf life and an ecolabel is positive; however, using the smart label creates disutility for consumers, thereby hindering acceptance of new labeling technology that may facilitate food waste reduction in the milk industry. These findings imply that retailers should find alternative means to enhance the communication of precise shelf life information and its role in reducing food waste.

Effect and formulation of ecolabel policy: A perspective of green supply chain decision and coordination.

Ecolabel policy has become an important strategy to encourage the consumption of green products throughout the world, contributing to sustainable development which is an inevitable choice for human society. Considering the manufacturer's reputation, consumer's environmental awareness, and effects of ecolabel certification on product demand, this study proposes several Stankelberg game models containing one manufacturer and one retailer to compare the optimal decisions and the impacts on the green supply chain with/without ecolabel certification, where four different scenarios are investigated in the centralized and decentralized situations. The results indicate that the ecolabel policy only functions below a threshold associated with the consumer's environmental awareness, which is higher in the decentralized situation. On the contrary, the optimal ecolabel standard in the centralized decision-making situation is higher than that in the decentralized ones if maximizing the environmental benefit. For the manufacturer, only when producing products as the ecolabel standard can it get the optimal profit. Finally, a wholesale price contract with the manufacturer's reputation is proposed, which improves the product's green degree and the environmental benefit to the optimal level in a decentralized supply chain.

Methodological guidelines for the calculation of a Water-Energy-Food nexus index for seafood products.

Indicators from life cycle assessment methodologies (i.e., footprints) have emerged as useful tools for identifying and communicating the environmental impacts of a system thanks to they are accessible and intuitive and easy to understand to non-expert public. However, the focus on a single environmental problem is one of their main drawbacks. From this idea arises the concept of Water-Energy-Food (WEF) nexus, with the aim of raising awareness of the connections between the universal rights to water supply, energy security and food provision. Regarding the latter, the fisheries sector stands out as a fundamental pillar in the fight against malnutrition. In this sense, the European project "blue growth" aims to ensure that the development of the marine sector is not linked to the degradation of its ecosystems. However, although producers and authorities are willing to communicate the sustainability of products, there is still no standard methodology for reporting it. With the purpose of remedying this current situation, this paper aims to provide technical guidance to calculate a single WEF nexus index for ecolabelling seafood products in the European framework (Atlantic area). Therefore, through this, it is expected to create a useful communication channel between producers and consumers through an easy-to-read ecolabel. Nonetheless, certain aspects, such as the footprints selected or the calculation procedures selected have to be reconsidered to refine the methodology proposed, apart from broadening the approach to other food sectors with the aim that the proposed eco-certification can be present in major supply and retail chains.

Assessing eco-label knowledge and sustainable consumption behavior in energy sector of Pakistan: an environmental sustainability paradigm.

The energy needs of Pakistan have increased many folds in recent years due to improved lifestyle, ever-increasing population, and economic development. Though the government and private sectors are considering efficient energy resources to overcome energy scarcity in the country, studies focusing on assessing consumers' sustainable consumption behavior in the form of energy-saving home appliances are limited in the country. This study aims to address this research gap and also contribute by augmenting the theoretical mechanism of the theory of planned behavior by including three unique dimensions (eco-label knowledge, attitude toward environment, and customer green trust) to comprehensively analyze sustainable consumption behavior in the Pakistani context. An analysis is performed on survey data of 631 consumers in the four largest cities of Pakistan: Karachi, Lahore, Faisalabad, and Islamabad. For the purpose of evaluating formulated hypotheses, the structural equation modeling approach is employed. Empirical findings suggest that eco-label knowledge positively and significantly influences attitude toward environment and consumer green trust. Similarly, attitude toward environment and consumer green trust has a positive and significant influence on purchase intention. Moreover, a significant positive relationship exists between consumer green trust and purchase intention. The research outcomes further disclose that purchase intention positively and significantly influence paying attention to environmental labels. These findings contribute to the literature on sustainable consumption behavior and provide academics and practitioners with future directions to transform social norms, raise consumers' awareness, and redesign policy frameworks through integrative and consistent efforts.

Telling You More Fluently: Effect of the Joint Presentation of Eco-Label Information on Consumers' Purchase Intention.

An eco-label is an important tool for identifying green products in the marketplace. Most eco-labels, however, present a single icon that is simple and carries limited information, thus creating cognitive barriers for consumers. As a result, eco-labels might not always effectively promote green consumption. Based on dual coding theory and the spatial contiguity effect, this study investigated the effect of the "joint presentation of eco-label information" (JPEI), which adds (functional/emotional) descriptive text to eco-labels, on improving consumers' cognitive fluency in eco-labels and subsequent purchase intention. We conducted three studies and found that, compared with the "single presentation of eco-label information" (SPEI), JPEI improved the cognitive fluency of consumers with low eco-label knowledge. Furthermore, spatially contiguous JPEI was more effective than spatially partitioned JPEI for consumers with low eco-label knowledge. In addition, we specifically explored the information types of JPEI that were effective for consumers with low eco-label knowledge. Low-construal consumers had higher cognitive fluency and higher purchase intentions under functional JPEI, and high-construal consumers had higher cognitive fluency and higher purchase intentions under emotional JPEI. The results of this study enrich eco-label research and can provide theoretical guidance for marketing practices in eco-labels.

Can the Part Replace the Whole? A Choice Experiment on Organic and Pesticide-Free Labels.

Chemical pesticides are a serious impediment to agricultural sustainability. A large-scale reduction in their use to secure food supplies requires more innovative and flexible production systems. Pesticide-free production standards bring together the strengths of all participants in the food value chain and could be the catalyst for this transition. Using a choice experiment approach and green tea as an example, this study investigated consumers' preferences for organic and pesticide-free labels. According to the findings, organic and pesticide-free labels and brands are all major factors that affect consumers' purchase decisions. Consumers are more willing to pay for organic labels than pesticide-free labels. There is a substitution effect between organic labels and pesticide-free labels. Complementary effects exist between organic labels and national brands, pesticide-free labels, and national brands. Consumer trust has an impact on consumers' choice of organic labels and pesticide-free labels. The use of pesticide-free labels is an alternate approach for small- and medium-sized businesses in a specific market to lower the cost of organic certification.

Ecolabeled seafood and sustainable consumption in the Canadian context: issues and insights from a survey of seafood consumers.

The concept of sustainable consumption is a much debated practice that has been seen as an outcome of the emergence of ecological citizenship-a concept that brings together the citizen and the environment in a framework that is underlined by social justice considerations and incorporates a vision of citizenship that involves both the private sphere and the public sphere of human activity. This study examines Canadian consumer awareness and uptake of certified sustainable seafood. We introduce the concepts ecological citizenship and sustainable consumption as a way of framing our research. Seafood ecolabels may be a valuable tool in translating general environmental concern about the marine environment into more sustainable fisheries practices. We conducted an on-site consumer survey in the Greater Toronto Area and a nearby city. Our findings showed that in contrast to high levels of awareness of the importance of the marine environment and the sustainability of seafood, consumers had a limited understanding about the meaning of sustainability in the case of seafood, and little knowledge about actual ecolabels found in the Canadian marketplace. Attitudes towards the marine environment and sustainable seafood, understanding of the meaning of seafood sustainability, and purchasing behaviors of sustainable seafood were significantly different by some socio-demographic characteristics. Positive attitudes towards the marine environment and sustainable seafood and better understanding of seafood sustainability were significantly associated with the increased purchasing of ecolabeled seafood. Lack of understanding of ecolabels, limited information about product sustainability, and lack of in-store guidance were identified as key barriers to purchasing ecolabeled seafood products.

Understanding Students' and Science Educators' Eco-Labeled Food Purchase Behaviors: Extension of Theory of Planned Behavior with Self-Identity, Personal Norm, Willingness to Pay, and Eco-Label Knowledge.

This study aims to understand antecedents of students' and science educators' purchasing behaviors for eco-labeled foods with the extended Theory of Planned Behavior (TPB) model including self-identity, personal norm, willingness to pay, and eco-label knowledge in the Turkish context. A web-based survey was used to collect data from 3,393 people including middle school students, high school students, pre-service science teachers, science teachers, and academic staff. The results revealed that both the original (32%) and extended (37%) TPB models successfully explained intentions to purchase eco-labeled foods. In addition, personal norm, eco-label knowledge, and intention explained 25% of the variance in purchase behaviors indicating an acceptable explanatory power. In the original TPB model, attitude and perceived behavioral control had positive influence on intention, and in addition to those factors, willingness to pay and self-identity had a positive effect on intention in the extended TPB model. However, subjective norm had no significant influence on intention for both models. As a result, the study has important practical implications for policy and curriculum makers, education stakeholders, and science educators.

Trends in biodiversity and habitat quantification tools used for market-based conservation in the United States.

Market-based conservation mechanisms are designed to facilitate the mitigation of harm to and conservation of habitats and biodiversity. Their potential is partly hindered, however, by the quantification tools used to assess habitat quality and functionality. Of specific concern are the lack of transparency and standardization in tool development and gaps in tool availability. To address these issues, we collected information via internet and literature searchers and through conversations with tool developers and users on tools used in U.S. conservation mechanisms, such as payments for ecosystem services (PES) and ecolabel programs, conservation banking, and habitat exchanges. We summarized information about tools and explored trends among and within mechanisms based on criteria detailing geographic, ecological, and technical features of tools. We identified 69 tools that assessed at least 34 species and 39 habitat types. Where tools reported pricing, 98% were freely available. More tools were applied to states along the U.S. West Coast than elsewhere, and the level of tool transferability varied markedly among mechanisms. Tools most often incorporated conditions at numerous spatial scales, frequently addressed multiple risks to site viability, and required 1-83 data inputs. Most tools required a moderate or greater level of user skill. Average tool-complexity estimates were similar among all mechanisms except PES programs. Our results illustrate the diversity among tools in their ecological features, data needs, and geographic application, supporting concerns about a lack of standardization. However, consistency among tools in user skill requirements, incorporation of multiple spatial scales, and complexity highlight important commonalities that could serve as a starting point for establishing more standardized tool development and feature-incorporation processes. Greater standardization in tool design may expand market participation and facilitate a needed assessment of the effectiveness of market-based conservation.

Tendencias en la Biodiversidad y en las Herramientas de Cuantificación de Hábitat Usadas para la Conservación Basada en el Mercado en los Estados Unidos Resumen Los mecanismos de conservación basada en el mercado están diseñados para facilitar la mitigación del daño y la conservación de los hábitats y la biodiversidad. Sin embargo, el potencial de estos mecanismos está parcialmente reducido por las herramientas de cuantificación usadas para evaluar la calidad y funcionalidad del hábitat. Son de preocupación específica la falta de transparencia y la estandarización del desarrollo de herramientas y los vacíos en la disponibilidad de las herramientas. Para tratar estos temas recolectamos información por medio del internet y los buscadores de literatura y a través de conversaciones con los desarrolladores y usuarios de las herramientas utilizadas en los mecanismos de conservación en los Estados Unidos, como la eco-etiqueta y los programas de pago por servicios ambientales (PES, en inglés), el banco de conservación y el intercambio de hábitats. Resumimos la información sobre las herramientas y exploramos tendencias entre y dentro de los mecanismos basados en criterios que detallan las características geográficas, ecológicas y técnicas de las herramientas. Identificamos 69 herramientas que evaluaron al menos a 34 especies y 39 tipos de hábitat. En donde las herramientas reportaron tarificación, el 98% estaban disponibles gratuitamente. Más herramientas estaban aplicadas a estados ubicados a lo largo de la costa oeste de los Estados Unidos que en cualquier otro sitio y el nivel de transferibilidad de las herramientas varió notablemente entre los mecanismos. Las herramientas comúnmente incorporaron las condiciones a numerosas escalas espaciales, trataron con frecuencia los múltiples riesgos para la viabilidad de sitio y requirieron 1 - 83 entradas de datos. La mayoría de las herramientas requirió un nivel moderado o mayor de habilidad para el usuario. Los estimados medios de la complejidad de las herramientas fueron similares entre todos los mecanismos, a excepción de los programas PES. Nuestros resultados ilustran la diversidad de características ecológicas, necesidades de datos y aplicación geográfica que existe entre las herramientas, lo que respalda las preocupaciones sobre la falta de estandarización. Sin embargo, la consistencia entre las herramientas en cuanto a los requerimientos de habilidades para el usuario, la incorporación de múltiples escalas espaciales y la complejidad resaltan las similitudes importantes que podrían servir como punto inicial para el establecimiento de un desarrollo más estandarizado de herramientas y procesos que incorporen las características del sitio. Una mayor estandarización del diseño de herramientas podría expandir la participación del mercado y facilitar una urgente evaluación de la efectividad de la conservación basada en el mercado.

A cross-cultural perspective on impact of health and nutrition claims, country-of-origin and eco-label on consumer choice of new aquaculture products.

Over the last decade, an increasing number of new value-added aquaculture products made their way onto the European market, as a response to growing demand for healthier diet, and more sustainable and locally produced protein sources. The importance of these drivers of consumer choice for aquaculture products' acceptance paves the way for a relevant reorientation of the European aquaculture industry towards a more consumer-centred approach. This research uses discrete choice experiments to examine the effect of health and nutrition claims, country-of-origin (COO), and eco-labels on consumer choice of new aquaculture products in a cross-cultural context. Three products with different preserving methods have been chosen for the study: fresh (chilled), canned, and smoked product. Results indicate that COO label "produced in own country" together with ASC eco-label function better than the health and nutrition claims as driver of choice. Results further point to the existence of different segments of "nutrition conscious", "ethnocentric", "price conscious", and "eco-conscious" consumers.

Who determines sustainability?

Over the past 20 years many different certification or rating schemes for sustainable fisheries have evolved, that attempt to influence consumer tastes and preferences and thereby incentivise better fisheries practices. This short review paper aims to document the history of such schemes, to consider their apparent differences and the basis upon which sustainability standards were developed. While there is some consistency between schemes in terms of the elements that should be considered as part of sustainability, and the general outcomes that sustainable fisheries should strive for, with the exception of maximum sustainable yield (MSY) there is less agreement on the specific details of how this should be measured or what reference points should be considered as sustainable. This arises from a lack of specific consideration or agreement on these issues in the international policy community.

To clean or not to clean? A critical review of beach cleaning methods and impacts.

Cleaning is a fundamental concern of beach managers in many destinations as well as an important requirement in beach quality awards. However, it has been largely neglected in the literature. This paper provides an overview of empirical studies on beach cleaning and analyzes cleaning-related requirements of 11 beach awards that generate controversy in the literature. This study comments on key aspects of beach cleaning, resolves various misconceptions, and provides new perspectives by integrating related topics drawn from a wide range of literature. The arguments based on both the ecological and tourism managerial perspectives are presented, indicating the gaps and proposing research solutions. The paper calls for empirical studies with regard to the efficiency of different cleaning approaches on beaches with varying levels of use intensity and for methodological designs that separate the impacts of mechanical grooming from those of trampling, dune destruction, shore armoring, artificial lighting, among others.

Environmental impacts and consumer preference for sustainably cultivated Japanese mustard spinach, komatsuna.

Sustainable agriculture is spreading in Japan in response to growing concerns about the environmental burden of the agriculture sector, but less than 1% of the total crop area for each vegetable in Japan is grown sustainably. Environmentally friendly agricultural products are produced by using organic and low-input farming techniques; low-input farming aims to reduce chemical inputs, such as fertilizers, pesticides, and herbicides, by half. Here, we used komatsuna (Japanese mustard spinach, Brassica rapa var. perviridis) as a model vegetable to study the environmental impact of low-input farming and ways to promote the purchase of organically and low-input farmed vegetables. We first assessed greenhouse gas emissions resulting from organic, low-input, and conventional farming of komatsuna. We also evaluated the effectiveness of providing consumers with detailed farm management and seasonality information to market organically and low-input farmed vegetables. We estimated marginal willingness-to-pay (MWTP) using choice-based conjoint analysis, based on attributes of price, fertilizer use, pesticide use, and region of origin. For seasonality, the questionnaire incorporating these attributes was conducted twice: once assuming purchasing in season, the other out of season. The greenhouse gas emissions of organic farming per area (196.7 kg CO2-eq/10 a/year) and per yield (72.3 kg CO2-eq/t/year) were less than those of low-input (322.6 kg CO2-eq/10 a/year, 120.7 kg CO2-eq/t/year) and conventional (594.0 kg CO2-eq/10 a/year, 220.7 kg CO2-eq/t/year) farming. MWTPs were highest for pesticide-free komatsuna (76.9 yen out of season, 66.2 yen in season), followed by full organic fertilizer (66.0 yen out of season, 63.4 yen in season), half organic fertilizer (35.8 yen out of season, 19.8 yen in season), and half pesticide (29.2 yen out of season, 21.0 yen in season). Consumers showed greater preference for organically and low-input farmed komatsuna out of season than in season. Consumers were more interested in pesticide information than in fertilizer and region of origin information. Our findings suggest that providing detailed cultivation and seasonality information would be a beneficial consumer communication tool to increase the market for sustainable agricultural products.

Estimating chemical ecotoxicity in EU ecolabel and in EU product environmental footprint.

The EU Commission Ecolabel and the Product and Environmental Footprint (PEF) aim at promoting the development and consumption of greener products. The product aquatic toxicity score from these 2 methods may lead in some circumstances to opposite conclusions. Although this could be interpreted as an inconsistency, the score should not be compared to each other but used in a complementary way. In short, CDV provided a "full" product formula aquatic toxicity score, even if some chemicals may never reach or persist in freshwater ecosystems. The USEtox® score, by integrating fate and exposure, focuses on the potential toxicity of persistent-water-soluble chemicals at steady state. Since no risk or safety assessment can be conducted with USEtox® nor with the CDV, both are a hazard-based scoring system. This short communication clarifies the difference between approaches underpinning the toxicity scores used in Ecolabel and PEF, providing guidance on how to interpret the results.

Development and use of microbial-based cleaning products (MBCPs): Current issues and knowledge gaps.

Cleaning products containing microbes as active ingredients are becoming increasingly prevalent as an alternative to chemical-based cleaning products. These microbial-based cleaning products (MBCPs) are being used in domestic and commercial settings (i.e., households and businesses) and institutional settings (e.g., hospitals, schools, etc.), in a variety of cleaning activities (hard surface cleaning, odour control, degreasing, septic tank treatments, etc.). They are typically described as "environmentally friendly" and "non-toxic". Publicly available information sources (scientific literature, patent databases, commercial websites) were searched for information on microbial species contained in MBCPs, their mode of action, cleaning applications in which they are used, and their potential impacts on human health and the environment. Although information was found providing a broad indication of microbial genera/species used, information on specific species/strains and quantities produced and sold is generally lacking. This makes it difficult to conduct a meaningful examination of any risks to human health and the environment from the production and use of MBCPs and to determine how effective current policies and regulatory frameworks are in addressing these issues. These and other challenges were addressed at an international workshop in Ottawa, Canada in June 2013 by a number of stakeholders, including industry, government, academic and non-governmental organizations.

Role of ecolabeling in reducing ecotoxicology.

Ecolabeling helps consumers to select environment friendly products, while meeting high demands on occupational health, safety, and usability. Ecolabeling undertakes cradle-to-grave approach which helps in minimizing the toxicological impacts at every stage of the product life cycle. The ecolabeling procedure calls for substitution or reduction of hazardous substances thereby reducing the toxicity caused due to these chemicals. China, Japan, Australia, European Union, and Nordic countries are leading in the race of awareness and implementation of ecolabeling schemes. In India, the ecolabeling scheme (Ecomark) was initiated in 1991. The Ecomark scheme lacked adoption of the green marketing principles and thus failed to create an impact. This study presents an overview of ecolabels in European Union, Nordic countries, Germany, China and India. Furthermore, it assesses the awareness of ecolabels among the retailers and traders of environment friendly products in India through a survey. The study highlights that the ecolabels are a success in most of the countries studied and are applied across a range of industrial sectors. The survey is administered to 80 retailers and traders of stores selling environment friendly products across different Indian cities. A correlation is established with the variables identified. The survey results indicate that although the retailers and traders of environment friendly products have low awareness of the ecolabels on environment friendly products, they are taking considerable efforts to promote and deliver environment friendly products to consumers. Large-scale awareness drives initiated by the Ministry of Environment, Forests & Climate Change permeating at grass root levels with the involvement of stakeholders could prove beneficial for promotion of the ecolabeling schemes.
