Does an energy efficiency label alter consumers' purchasing decisions? A latent class approach based on a stated choice experiment in Shanghai

In this paper we conducted a hypothetical choice experiment in Shanghai, China, to examine whether the China Energy Efficiency Label influences consumers' choices of air conditioners and refrigerators. A latent class approach was applied to observe both heterogeneities among the respondents and product brands. Our results suggested that consumers in Shanghai were well aware of the China Energy Efficiency Label and tended to pay more attention to products with such labels. In addition, air conditioners and refrigerators affixed with a hypothetical label that indicates saving in electricity bills compared with a standard model received significant preferences, which suggested that the more information manufacturers provide, the more their products would be preferred by consumers. Finally, weighted by class probability, the willingness to pay values for more energy efficient refrigerators were higher than those for more energy efficient air conditioners, implying that Shanghai consumers have greater incentive to pay more for appliances they use more frequently.     

Consumer Autonomy and Sufficiency of GMF Labeling

Individuals’ food choices are intimately connected to their self-images and world views. Some dietary choices adopted by consumers pose restrictions on their use of genetically modified food (GMF). It is quite generally agreed that some kind of labeling is necessary for respecting consumers’ autonomy of choice regarding GMF. In this paper, we ask whether the current practice of mandatory labeling of GMF products in the European Union is a sufficient administrative procedure for respecting consumers’ autonomy. Three issues concerning this question are discussed. First, we argue that labeling needs to be accompanied by relevant and understandable information on genetic modification, genetically modified food, and the European practice of GMF labeling. Second, we claim that this type of informing makes it less likely that consumers start to avoid GMF products just because labels make them suspicious of the products. It is further noted that even though some consumers may react to labels this way, labels do not restrict their autonomy of choice. Third, a need for more precise labels indicating the source of the transferred gene is considered. It is found out that such labels are not morally necessary when also non-GMF products are available and no relevant differences (such as differences in price and healthiness) exist between them and GMF products. However, in some other cases more precise labels may be needed for respecting consumers’ autonomy of choice.     

Linking sustainable consumption and production: The government role

Achieving sustainable development depends on comprehensive approaches which integrate consumption and production initiatives. At present, sustainable consumption is being overemphasized to the neglect of the more important production side. This paper examines the role of governments in promoting sustainable consumption and production to identify gaps in national schemes which reduce their overall effectiveness. Public policy tools promoting sustainable consumption and production are discussed in terms of whether they are aimed at correcting: 1) market failures (regulations, taxes, subsidies); or 2) systems failures (labels, communications, education, public procurement). The challenge for governments is to link sustainable consumption initiatives to policies aimed at increasing the sustainability of production in the private sector in both their national and international dimensions. In this way, governments can enlist the aid of consumers in pushing producers towards sustainability and to achieve the ultimate goal of sustainable development.     

Practices of energy use management and sustainable performance in Brazilian mineral industries

Energy is an essential asset for the existence of industrial activities, however, the absence of energy use management may lead to numerous environmental, economic, and social impacts. Thus, industries, which are major consumers of energy, play an essential role in seeking to preserve the energy system. This study aimed at analyzing the practices of energy use management and their relation to sustainable performance in the industries within the Brazilian mineral sector. The practices of energy use management were measured using the model proposed by Liu et al. (2012, Journal of Cleaner Production, 26, 79–89). After that, evidence of sustainable performance was identified based on performance indicators developed by the Global Reporting Initiative (2006, 2010, 2014). The study is characterized as quantitative, and it was conducted through a survey of industries linked to the Brazilian Mining Association. Through our results, we verified that the practices related to energy use management existent in the companies that we studied are subjected to periodic verification of the impacts caused by company activities on the environment, and that attention to energy use provides an incentive to daily practices of energy saving. On the other hand, the practices of energy use management are still little disseminated among these companies, as is certification to the International Organisation for Standardization's (ISO) Energy Management Systems framework, ISO 50001. In general, through the analyses that we performed, we can verify the existence of positive associations between the factors related to the practices of energy use management and to corporate sustainable performance.     

Knowledge, values, uses and management of the Araucaria araucana forest by the indigenous Mapuche Pewenche people: A basis for collaborative natural resource management in southern Chile

One of the most important endemic tree species of Chile and at the same time one of the most endangered ones is Araucaria araucana (Mol.) C. Koch, the monkey‐puzzle tree. It grows in the Andes Mountains, homeland of the indigenous Mapuche Pewenche people who depend on this tree. This paper is based on field research that investigated the ecological knowledge, uses and management of the Araucaria araucana forest by indigenous Mapuche Pewenche people based on the socio‐cultural, spiritual and ecological relationships they have with the Araucaria forest, to find out how indigenous people and their knowledge could contribute to sustainable Araucaria forest management. A Mapuche Pewenche community located in the IX region of Chile contributed to this study. Based on the analyses this paper illustrates the nature of indigenous ecological knowledge of Araucaria araucana on the one hand, and its utility in native forest management on the other. The research shows that the Mapuche Pewenche hold ecological knowledge and conduct practices to manage their Araucaria forest in a balanced way. They conserve and use forest biodiversity at one and the same time. This paper provides recommendations for sustainable Araucaria forest management and conservation strategies ex‐situ and in‐situ incorporating indigenous knowledge and scientific knowledge and for promoting a collaborative natural resources management.     

Consumer understanding of product lifetimes

Throwing products away before they fail or are broken is at the heart of consumer behaviour in developed economies such as the UK. Products are often discarded for reasons of fashion, or to keep up with technological advances, rather than because they have reached the end of their functional life. Such behaviours contribute to resource depletion, greenhouse gas emissions, and physical waste which needs to be managed. Extending the length of time that products are kept in use (whether by their original or subsequent owners) can contribute to greater resource efficiency, with significant potential to reduce greenhouse gas emissions. This research was undertaken to support the development of evidence-based policy in the UK on the role of longer product lifetimes in achieving sustainable consumption and waste prevention. Twelve qualitative discussion groups, involving 115 consumers, were carried out to explore consumer influences on product lifetimes including: which factors influence purchase decisions; the care of products in use; and disposal decisions. A new typology was developed to describe how products meet consumers’ various needs for ‘workhorses’, ‘investment’ and ‘up-to-date’ products; and how lifetime is an outcome of the ‘nature’ of a product (functional life) and its ‘nurture’ (lifetime in use) by consumers. The results demonstrate that consumers have come to expect constant and rapid up-dating of products. In particular, having the latest versions of products is strongly associated with personal identity and feelings of success in life. There is little evidence of concern about the environmental consequences of a ‘throwaway society’. The low cost of new products, which enables rapid updating for reasons of fashion, is a key barrier to encouraging consumers to keep products in use for longer. Some opportunities were identified however for certain ‘workhorse’ and ‘investment’ products that are valued more for their functionality than fashion.     

Pessimism and Optimism in the Debate on Climate Change: A Critical Analysis

Successful transitions to a sustainable bioeconomy require novel technologies, processes, and practices as well as a general agreement about the overarching normative direction of innovation. Both requirements necessarily involve collective action by those individuals who purchase, use, and co-produce novelties: the consumers. Based on theoretical considerations borrowed from evolutionary innovation economics and consumer social responsibility, we explore to what extent consumers’ scope of action is addressed in the scientific bioeconomy literature. We do so by systematically reviewing bioeconomy-related publications according to (i) the extent to which consumers are regarded as passive vs. active, and (ii) different domains of consumer responsibility (depending on their power to influence economic processes). We find all aspects of active consumption considered to varying degrees but observe little interconnection between domains. In sum, our paper contributes to the bioeconomy literature by developing a novel coding scheme that allows us to pinpoint different aspects of consumer activity, which have been considered in a rather isolated and undifferentiated manner. Combined with our theoretical considerations, the results of our review reveal a central research gap which should be taken up in future empirical and conceptual bioeconomy research. The system-spanning nature of a sustainable bioeconomy demands an equally holistic exploration of the consumers’ prospective and shared responsibility for contributing to its coming of age, ranging from the procurement of information on bio-based products and services to their disposal.

     

Environmental labelling in The Netherlands: a framework for integrated farming

This article compares four Dutch environmental certification schemes for agricultural food crops, analysing their methodology and the completeness of their criteria on five aspects: pesticide use, nutrient use, water management, energy and materials consumption, and habitat management. The least stringent of the labels, the MBT ('Environmentally Aware Cultivation') certificate, serves mainly to increase farmers' awareness of nutrient and pesticide use. With regard to both administrative obligations and actual management practices, the MBT label largely mirrors the terms of standing Dutch legislation. The CC ('Controlled Cultivation') and AMK ('Agro-Environmental') labels comprise more and more stringent criteria. With their restrictions on nutrient and pesticide use, these two labels serve as the two principal labels in the field of integrated agriculture. There is little difference between the two and it is recommended that they be merged, on the basis of a standardised definition of integrated agriculture. The EKO ('Organic Agriculture') label proceeds from different principles, but as a minimum should also comply with Dutch legislation without exception. For both integrated and organic agriculture, in addition to criteria on pesticide and nutrient use, criteria should also be developed for water management, energy and materials use and habitat management. The relationship between the criteria and their respective thresholds and Dutch legislation is also addressed. Existing criteria are frequently specified in such a way that the environmental benefits cannot be ascertained. This is a serious drawback for the parties further down the chain: auctioneers, retailers and consumers. It is recommended to develop qualitative guidelines for an Agricultural Stewardship Council at international level, like the Forest Stewardship Council, and a separate label for integrated agriculture per country comprising quantitative criteria for all relevant aspects of farming operations.     

Labeling Products of Biotechnology: Towards Communication and Consent

Recently, both consumers and producers ofbiotechnology products have insisted thatcommunication between the two be improved. The formerdemand more democratic participation in the riskassessment process of biotechnology products. Thelatter seek to correct misinformation regardingalleged risks from these products. One way to resolvethese concerns, I argue, is through the use ofbiotechnology labels. Such labeling fosters consumerautonomy and moves toward more participatory decisionmaking, in addition to ensuring that informed consentfrom consumers is maintained. Furthermore, althoughvoluntary biotech-free labeling in lieu of biotechlabels may uphold consumer sovereignty, the latterremains a more effective strategy for achievingethical communication between consumers and producersof biotechnology products.     

Elderly Adi Women of Arunachal Pradesh: “Living Encyclopedias” and Cultural Refugia in Biodiversity Conservation of the Eastern Himalaya, India

Elderly women of a particular socioecological system are considered to be “living encyclopedias” in biocultural knowledge systems. These women play a pivotal role in retaining and passing on biodiversity-related traditional knowledge to the next generations. Unfortunately the fast changing sociocultural values and the impact of modernity have rendered their knowledge somewhat less valuable and they are being treated as “cultural refugia.” Our study on the importance of these women in the conservation of indigenous biodiversity was conducted in 14 randomly selected villages dominated by the Adi tribe of East Siang District, Arunachal Pradesh (northeast India). Data were collected from 531 women (381 elderly and 150 young to middle aged) during 2003–2008 using conventional social science methods and participatory rural appraisal. One innovative method, namely “recipe contest,” was devised to mobilize Adi women of each village in order to energies them and explore their knowledge relating to traditional foods, ethnomedicines, and conservation of indigenous biodiversity. Results indicated that 55 plant species are being used by elderly Adi women in their food systems, while 34 plant species are integral parts of ethnomedicinal practices. These women identified different plant species found under multistory canopies of community forests. Elderly women were particularly skilled in preparing traditional foods including beverages and held significantly greater knowledge of indigenous plants than younger women. Lifelong experiences and cultural diversity were found to influence the significance of biodiversity use and conservation. The conservation of biodiversity occurs in three different habitats: jhum lands (shifting cultivation), Morang forest (community managed forests), and home gardens. The knowledge and practice of elderly women about habitats and multistory vegetations, regenerative techniques, selective harvesting, and cultivation practices contribute significantly to food and livelihood security while sustaining an array of threatened plant species. Basically, knowledge of elderly women on using biodiversity in food and medicinal systems was found in three categories namely: “individual,” “community,” and “refined.” We identified a need to develop holistic policies to recognize and integrate knowledge and practices of elderly women with local level of planning on sustainable conservation of biodiversity as well as community-based adaptations.     

Sustainable Engineering Science for Resolving Wicked Problems

Because wicked problems are beyond the scope of normal, industrial-age engineering science, sustainability problems will require reform of current engineering science and technology practices. We assert that, while pluralism concerning use of the term sustainability is likely to persist, universities should continue to cultivate research and education programs specifically devoted to sustainable engineering science, an enterprise that is formally demarcated from business-as-usual and systems optimization approaches. Advancing sustainable engineering science requires a shift in orientation away from reductionism and intellectual specialization towards integrative approaches to science, education, and technology that: (1) draw upon an ethical awareness that extends beyond the usual bounds of professional ethics or responsible conduct of research to include macroethics, (2) adopt anticipatory and adaptive approaches to unintended consequences resulting from technological innovation that result in more resilient systems, and (3) cultivate interactional expertise to facilitate cross-disciplinary exchange. Unfortunately, existing education and research training programs are ill-equipped to prepare scientists and engineers to operate effectively in a wicked problems milieu. Therefore, it is essential to create new programs of graduate education that will train scientists and engineers to become sustainable engineering science experts equipped to recognize and grapple with the macro-ethical, adaptive, and cross-disciplinary challenges embedded in their technical research and development programs.     

Is animal welfare a central issue for consumers of luxury goods?

The compatibility between luxury and sustainable development has been increasingly examined in recent literature, but a number of ethical issues remain unexplored. One such concern is animal welfare, a recurrent question in the luxury goods sector. This is one of the first research articles to shed light on this subject, utilising two studies, one qualitative and the other quantitative with conjoint analysis, conducted among 12 and 253 French consumers, respectively. The results reveal that consumers are sensitive to the challenge of animal welfare in luxury, but fall into two different groups. Some have a preference for animal‐based raw materials sourced from livestock farms that respect animal welfare, whilst others are more favourable to the use of synthetic raw materials. In particular, the results show that the use of synthetic raw materials is accepted by some consumers but can lead to a reduction in the perceived value of luxury products.     

Thinking Habits into Action: The role of knowledge and process in questioning household consumption practices

Despite occupying a central place in the sustainable development paradigm, calls for individuals in high-income countries to adopt patterns of sustainable consumption have failed to gain ground in the past decade. The low uptake of public messages that emphasise links between the environment and the home are caused by a plethora of 'barriers to action', which range from individual circumstances to public norms and structures. This article argues that in addition to these barriers, consideration of how individuals read and react to sustainable consumption information is important. Based on interviews with participants of a sustainable behaviour change programme called Action at Home, this article considers both how, and in what form, knowledge is mobilised when individuals rethink their personal practices. Using Giddens' structuration theory, a framework is presented. This framework emphasises the importance of 'known' or 'local' information, as well as discursive processes, in addressing individual consumption practices and argues that a 'cultural politics' of sustainable consumption needs to be factored into on-going academic and policy debates.     

PET containers in Brazil: Opportunities and challenges of a logistics model for post-consumer waste recycling

The use of post-consumer materials is directly related to reducing the cost of production and extraction of natural resources. Non-recyclable materials are randomly disposed in the environment. Brazil is one of the largest consumers of PET (polyethylene terephthalate) bottles. The purpose of this paper is to describe the opportunities and challenges of the logistics model for post-consumer PET bottle recycling in Brazil, while providing knowledge of its practices along the recycling chain. The results describe the need to educate those directly and indirectly involved in the process; to reduce consumption in order to reduce the amount of waste generated; to structure the post-consumer reverse chain and engage industrial sectors and government, through public policies, to support cleaner technologies along the PET bottle production chain.     

Myths and realities of the “new” green economy

This article details new research showing that the majority of U.S. consumers have strong inclinations to buy earth-sustainable food products. Contrary to prevailing beliefs in the industry, the market potential for these products is enormous—52 percent of consumers are willing to buy “green,” and nearly one-third (30 percent) can actually be considered as the core market for earth-sustainable food products. Yet these products currently represent only 2 percent of all food sales. This immense gap can be eliminated by turning our focus from supply (an endless stream of new product introductions) to demand (the needs of the consumer). Doing so requires a clear understanding of the consumer and the dispelling of several myths that pervade the marketplace today. Information in this article was taken from Phase 1 of The Hartman Report—Food and the Environment: A Consumer's Perspective, which examines the consumer segments in much more detail with regard to attitudinal, demographic, and psychographic profiles. The report was commissioned, in part, by The Kellogg Foundation, The Food Alliance, and Cascadian Farm. Phase II of the research more closely examines those segments that represent the key target markets for these products, including information on the effects of advertising, public relations, and labels in communicating environmentally sustainable product messages. Phase III will develop specific retail tactics that can be effective in delivering products and services to the most important segments.

An Interpretive Approach to Developing Volunteer-based Coastal Monitoring Programmes

The concept of sustainable development has highlighted the need to involve those who use a natural resource in helping to manage and maintain it. This has prompted the development of monitoring programmes involving volunteers who collect scientific data on the state of the natural environment. This paper argues that interpretation theory and practice provide a sound basis for the design and implementation of volunteer-based coastal monitoring programmes. Integration of multiple interrelated objectives in programmes relies on sound ‘audience’ research, including planned evaluation procedures. Three case-studies are presented which serve to identify and highlight the benefits of broadening the primary scientific focus of monitoring programmes to include greater consideration of participant motivations, skills and knowledge in the design and delivery of programmes. Discussion in this paper focuses on coastal monitoring programmes but the stated benefits might also be expected when applying this approach to other natural resource monitoring programmes.     

Dilemmas and advances in corporate social responsibility in Brazil. The work of the Ethos Institute

This article discusses the development of corporate social responsibility (CSR) in Brazil from the perspective of the Ethos Institute of Business and Social Responsibility. The Institute is a not‐for‐profit, non‐governmental organization, that has played a leading role in the Brazilian CSR effort. In Brazil, CSR initiatives have a long tradition of philanthropy, a consequence of the country's great social inequalities. The increased attention to corporate social responsibility has paralleled growing concern about sustainable development and the intensifying activities of pressure groups (consumers, customers, investors, NGOs, labour unions, the media, among others) that have been increasing since the 1990s as natural resources are progressively becoming exhausted, social tensions rising and environmental conditions deteriorating worldwide. This article identifies problems and obstacles to the growth of corporate social responsibility in Brazil, as well as advances and alternatives for CSR and towards creating conditions for the country to be internationally competitive and sustainable in the financial, social and environmental areas.     

The potential contribution of sustainable waste management to energy use and greenhouse gas emission reduction in the Netherlands

Future limitations on the availability of selected resources stress the need for increased material efficiency. In addition, in a climate-constrained world the impact of resource use on greenhouse gas emissions should be minimized. Waste management is key to achieve sustainable resource management. Ways to use resources more efficiently include prevention of waste, reuse of products and materials, and recycling of materials, while incineration and anaerobic digestion may recover part of the embodied energy of materials. This study used iWaste, a simulation model, to investigate the extent to which savings in energy consumption and CO₂ emissions can be achieved in the Netherlands through recycling of waste streams versus waste incineration, and to assess the extent to which this potential is reflected in the LAP2 (currently initiated policy). Three waste streams (i.e. household waste, bulky household waste, and construction and demolition waste) and three scenarios compare current policy to scenarios that focus on high-quality recycling (Recycling+) or incineration with increased efficiency (Incineration+). The results show that aiming for more and high-quality recycling can result in emission reductions of 2.3 MtCO₂ annually in the Netherlands compared to the reference situation in 2008. The main contributors to this reduction potential are found in optimizing the recycling of plastics (PET, PE and PP), textiles, paper, and organic waste. A scenario assuming a higher energy conversion efficiency of the incinerator treating the residual waste stream, achieves an emission reduction equivalent to only one third (0.7 MtCO₂/year) of the reduction achieved in the Recycling+ scenario. Furthermore, the results of the study show that currently initiated policy only partially realizes the full potential identified. A focus on highest quality use of recovered materials is essential to realize the full potential energy and CO₂ emission reduction identified for the Netherlands. Detailed economic and technical analyses of high quality recycling are recommended to further evaluate viable integrated waste management policies.     

Pesticide tolerance of Paenibacillus sp. D1 and its chitinase

Excessive use of pesticides in agriculture has led to several problems pertaining to loss of soil fertility and environmental degradation. Biological control agents offer the best alternative to reduce use of toxic pesticides. Paenibacillus sp. D1 isolated from the effluent treatment plant of a seafood processing industry exhibited broad spectrum tolerance towards a number of pesticides at concentrations higher than recommended for field applications. The isolate showed enhanced growth and chitinase production in the presence of some protectant fungicides. None of the tested demethylase inhibitor (DMI) fungicides inhibited growth and chitinase production except triadimefon. The isolate was also tolerant to most commonly used insecticides belonging to the organophosphate, carbamate and cyclodiene organochloride classes. Chitinase of Paenibacillus sp. D1 was found to be more tolerant than the organism itself and was highly stable in the presence of pesticides at the temperature under field conditions in Gujarat, India, i.e. 40 °C. This was suggestive of its potential in integrated pest management (IPM) to significantly reduce the use of harmful chemicals. To our knowledge this is the first extensive study on pesticide tolerance of the Paenibacillus species and its chitinase.     

Youth environmental attitudes in Australia and Brunei: implications for education

This paper explores similarities and differences in the knowledge, beliefs and actions that comprise the environmental attitudes of senior secondary school students in Australia and Brunei. Utilising data from a wider international study in Asia and the Pacific (Yencken et al. , 2000), the paper uses findings from these two countries to illustrate the pervasiveness of global environmental concerns over local cultural influences in the construction of youth environmental attitudes in Australia and Brunei. Thus, young people in these countries, as they do in all parts of the Asia-Pacific region, have very similar levels of environmental awareness and knowledge, sources of environmental, beliefs, systems or world views about the environment, and levels of perceived control over environmental trends. They also have a shared desire for schools to do more in the area of environmental education. The paper concludes that much more effort needs to be made in certain areas. The first is to encourage teachers and others who have influence over young people to develop their own knowledge and skills to be able to teach environmental education effectively. The second is in the area of curriculum and pedagogical reform so that young people explore the many possible ways in which current systems can change to support sustainability, in which current lifestyles reflect these systems, and in which their own actions can contribute to a sustainable future.
