The considerations and limitations of feedback as a strategy for behaviour change

Design for Sustainable Behaviour (DfSB) is a maturing research area concerned with the application of design strategies to influence consumer behaviour during a products use phase towards more sustainable action. However, current DfSB research has focussed on strategy selection with little research into understanding the real-world impact of the behaviour changing interventions debated. This article presents the results of an extensive literature review of one specific DfSB strategy, feedback – a user agentive performance indicator. These findings exemplify the considerations and limitations of this particular approach to behaviour change, drawing on empirical research conducted by a breadth of authors, including two of the only medium-term case studies in the field of DfSB. Considerations discussed include the frequency, duration and accuracy of feedback; the selection of metrics and the presentation medium and mode; the use of ambience and the location of the installation. Limitations of feedback include the need for additional information and comparisons; the issue with multiple users; technical issues; relegation to background technology and the potential rebound effects. This article provides insights to both improve the effectiveness of future feedback design efforts and also to help facilitate discussion on feedbacks position as a strategy within DfSB.     

Mapping out the design opportunities: pathways of sustainable behaviour

To advance the area of design for sustainable behaviour (DfSB), a common behaviour terminology is needed to enable comparisons of studies across application areas. Thus, the map of pathways of sustainable behaviour was created with the aim of charting different paths that users can follow to reduce environmental impact when interacting with artefacts. The construction of the map results from a comparative analysis of sustainable behaviours identified in previous studies in conjunction with a review of existing behaviour classifications. The proposed map of pathways gives a comprehensive overview of all artefact-related resource-consuming usage behaviours, organised according to a design perspective and divided with regard to aspects of use and obtainment, primary and secondary artefact, duration and type of effort. Through design, the user can be encouraged to take any of the five identified paths: choice of artefact, changed use, maintenance and repair, mediated use and regulated artefact. Using the map in a DfSB process can guide the exploration phase and highlight potential design opportunities when choosing target behaviour. If adopted by the DfSB community, the united typology of the map also provides means necessary to make rigorous comparisons and develop the field and its tools.     

The ethics in balancing control and freedom when engineering solutions for sustainable behaviour

Research suggests that to allow for sustainable development, consumption patterns must be changed. Individual behaviour is central to society's impact on the environment. However, due to the complexity of environmental issues, much of the political debate and technology development is inaccessible to consumers and based on the values, interpretations and priorities of experts. User‐centred, user‐involved and participatory processes are fundamental in design disciplines such as interaction design and participatory design. Research into the possibilities for cross‐pollination of design for sustainability and user‐centred design has distinguished several strategies for design‐led behavioural change. The strategies differ with regard to the levels of control and responsibility that users are left with, ranging from empowerment through information about consequences of behaviour to blocking behaviour or forcing sustainable practices upon individuals. By considering technological behaviour‐steering strategies in the light of science and technology studies and theory on technological mediation, the paper addresses the ethical issues that arise and discusses how designers can contribute to more sustainable consumption patterns without compromising quality of life, individual freedom and democratic rights.     

The implications of cultural differences in laundry behaviours for design for sustainable behaviour: A case study between the UK,India and Brazil

Traditional research into sustainable design has typically focused on reducing the environmental impact of products during the manufacture and disposal stages of a products' lifecycle. The last decade, however, has seen an explosion of research into understanding and moderating user behaviour during the use phase of a products' lifecycle; often the most resource-intensive phase. One of the biggest factors that affects behaviour is a users cultural context; however, the effect of cultural context on design for sustainable behaviour has had little exploration in this relatively new research field.     

Assessing sustainability in nature-inspired design

In the field of sustainable product development, a new perspective for approaching sustainability has been advocated, challenging designers and engineers to aim beyond ‘reducing unsustainability’. Several design strategies – including Biomimicry and Cradle to Cradle – have been suggested for developing truly sustainable, or ‘beneficial’, products. But do these strategies help in developing such products, and how to assess their ‘sustainability’? Based on a review of the objectives in nature-inspired design, we argue that assessing environmental sustainability is not straightforward. Whereas both Biomimicry and Cradle to Cradle build on the perspective of ‘achieving sustainability’, current life-cycle assessment-based tools are geared towards reducing current impacts. As a consequence, existing tools are insufficiently equipped for the purpose of the assessment: they do not cover some of the main results that nature-inspired design is set out to accomplish. To be able to include these results, we propose two new constituents to current life-cycle-based product assessment: assessing against conditions of sustainability and assessing ‘achievement’, the extent to which these conditions of sustainability have been achieved. Furthermore, the product context needs to be included for assessing beneficial impacts. This article discusses how these constituents can contribute to an assessment tool that enables designers and engineers to assess the development of environmentally sustainable solutions.     

The EU sustainable energy policy indicators framework

The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.     

Environmental implications of planned obsolescence and product lifetime: a literature review

The aim of this paper was to explore the implications of planned obsolescence (PO) and the associated product lifetime on the environmental impact of products. To achieve this task, a literature review was performed to assess both the historical context and recent situation of planned obsolescence. A search in scholarly journals was performed to evaluate to what extent product lifetime and PO have been discussed in the recent literature. Based on the findings, selected cases of PO are discussed and trends in the practice of limiting product lifetime are identified. Factors considered to have a significant influence on product lifetime have been identified and discussed. The discussion of case studies made it possible to establish the links between product design, manufacturing and associated impacts of lifetime. The role of the actors along the value chain is also considered to propose a business scheme, where the influences of consumer behaviour and design choices are crucial. Finally, strategies to facilitate the definition of different scenarios are given. These strategies may serve to increase the reliability of environmental assessment throughout a product life cycle.     

Understanding the entrepreneurs’ behavioural intentions towards sustainable tourism: a case study from Greece

This study’s aim is mainly to provide insights into the factors that affect sustainable tourism entrepreneurs’ behavioural intentions, employing data from Greece. Given that intention is a powerful predictor of actual behaviour, to stimulate sustainable entrepreneurial activity in the tourism sector and achieve sustainable development, it is important to study the factors that affect entrepreneur’s behavioural intentions towards sustainability. Findings through this empirical analysis support that entrepreneur’s demographics parameters and firm characteristics have distinctive effects in explaining respondents’ behaviour towards sustainable entrepreneurship and acknowledgement of sustainability options of a community. In particular, results suggest that younger entrepreneurs are probably more informed about the potential of the sustainability for the regions and are more likely to favour sustainable tourism practices. Entrepreneur’s income is also a statistical significant parameter towards sustainable entrepreneurship intentions within the tourism sector. Finally, entrepreneurs reported as important for the promotion of tourism sustainability the creation of knowledge networks and websites to focus on sustainable business and the promotion of environmental labels and certified management systems in tourism businesses.     

Does community resilience decrease social–ecological vulnerability? Adaptation pathways trade-off in the Bolivian Altiplano

Worsening climate change impacts and environmental degradation are increasingly supporting policies and plans in framing a linear understanding of resilience building and vulnerability reduction. However, adaptations to different but interacting drivers of change are unclear in the mix of opportunities and threats related to increasing connections, emerging technologies, new patterns of dependency and possible lock-in effects. This paper discusses a more open-ended understanding of the relationship between resilience and vulnerability, highlighting emerging trade-offs among adaptive capacities and exposures to different (and new) threats as they relate to social–ecological sustainability. The transition of the Southern Bolivian Altiplano, from being a remote rural area of subsistence farming to a global leader in quinoa production and exportation, has been taken as a study case. Results from 18 workshops organised within different communities provide insights about a range of trade-offs between community resilience attributes and social–ecological vulnerability induced from land use changes, livestock strategies, communities’ behavioural change and institutions’ emerging policies. The main theoretical advances of the paper relate to the need for critically framing multiple threat exposures and adaptive capacity trade-offs, contributing to arguing the usually positive meaning of resilience, and taking into account “to whom or to what is positive which adaptation” and “which trade-off should be accepted, and why”. Framing adaptive pathways through these questions would serve as a tool for addressing sustainable development goals, while avoiding lock-ins or unsustainable path dependencies.     

Sustainable product design using CAD: a case study in an Indian rotary switches manufacturing organisation

Sustainability is gaining importance in contemporary manufacturing organisations. Modern design engineers need approaches for creating environmentally friendly products. In this context, this paper reports a case study carried out in an Indian rotary switches manufacturing organisation. A component of the rotary switch has been modelled using computer-aided design. Then, the sustainability analysis has been carried out for determining the environmental impact. The environmental impact has been measured in terms of carbon footprint, energy consumption and air/water impacts. The handle design has been modified to minimise the environmental impact. The results of this case study indicate that appropriate modifications in design could lead to the development of sustainable design with minimal environmental impact.     

CAD and DFM: enablers of sustainable product design

Sustainability has been regarded as an important concept for survival in the contemporary scenario. Modern design engineers are in need of approaches for creating sustainable products. In this context, this paper reports a case study carried out in an Indian modular switches manufacturing organisation. The existing handle of the switch has been modelled using computer-aided design (CAD). Then, the sustainability analysis has been carried out for determining the environmental impact. This is followed by the redesign of the handle using design for manufacturability (DFM) principles. The sustainability has been measured in terms of carbon footprint, energy consumption and air–water impacts. It has been found that the redesigned handle possesses minimal environmental impact. It could be inferred from the results of the case study that CAD and DFM could lead to the development of sustainable product design with minimal impact on the environment.     

Design concept for an ecological relaxing textile product using solar energy

We can enhance our quality of life and reduce environmental impacts by making improvements in textile product design. By thinking about the environment when we design, choose and use technology, we can play an important part in building a better world for the future. If we are going to live in a sustainable way, the technology that we use has to be sustainable.

This paper provides an insight into how the design of textile products could provide for a more sustainable future. It describes a design concept for an ecological relaxing textile that uses photovoltaic cells to collect and store solar energy and to power an electronic relaxing system. This design may help improve our quality of life now and in the future.

The raw materials and processes, the electronic devices and the dimensions of solar energy for this application are analysed from an environmental perspective. The solar relaxing textile can facilitate our daily life by providing increased comfort and well being, and also acts as an indirect message to use renewable energy within textile support, in order to preserve our ecology.     

Making the user more efficient: design for sustainable behaviour

User behaviour is a significant determinant of a product's environmental impact; while engineering advances permit increased efficiency of product operation, the user's decisions and habits ultimately have a major effect on the energy or other resources used by the product. There is thus a need to change users' behaviour. A range of design techniques developed in diverse contexts suggest opportunities for engineers, designers and other stakeholders working in the field of sustainable innovation to affect users' behaviour at the point of interaction with the product or system, in effect ‘making the user more efficient’. Approaches to changing users' behaviour from a number of fields are reviewed and discussed, including: strategic design of affordances and behaviour‐shaping constraints to control or affect energy‐ or other resource‐using interactions; the use of different kinds of feedback and persuasive technology techniques to encourage or guide users to reduce their environmental impact; and context‐based systems which use feedback to adjust their behaviour to run at optimum efficiency and reduce the opportunity for user‐affected inefficiency. Example implementations in the sustainable engineering and ecodesign field are suggested and discussed.     

Strategic environmental assessment in Hong Kong

This review examines the development and application of strategic environmental assessment (SEA) process in the planning framework of Hong Kong. Two strategic planning case studies are evaluated within the context of SEA, namely the Territorial Development Strategy Review (TDS Review) and the Third Comprehensive Transport Study (CTS-3). Rapid population growth and urbanisation in Hong Kong, coupled with a historic lack of planning controls and inherent conflicts between government departments have been major obstacles to achieving sustainable development in the territory. Despite these challenges, Hong Kong was one of the first Asian countries to apply SEA to major development plans, where the implementation of the 'SUSDEV 21' study on sustainable development has demonstrated the government's commitment towards integrated environmental protection. The application of SEA has provided decision-makers with key information on potential environment impacts arising from proposed developments, resulting in greater accountability and transparency in the decision-making process. SEA in Hong Kong has also prompted an increased level of environmental awareness and co-operation between government departments and agencies responsible for the management of Hong Kong's natural and urban environments. However, the application of SEA in Hong Kong continues to have notable limitations. SEA needs to evolve beyond its current sectoral application to examine ways in which development decisions can not only pre-empt and prevent environmental damage, but also positively enhance and restore existing natural resources. Current land use plans and transportation strategies still largely determine the pattern of development in the near future without adequate longer-term environmental cost-benefit analysis. Sustainable development includes environmental, social and economic considerations, and these inter-related elements need be suitably balanced. SEA is not a means to obstruct development in Hong Kong, but should be recognised for its inherent socio-economic and ecological value, and fully integrated with the decision-making process. Whilst it is admirable that Hong Kong has taken positive steps in this direction, it is now an opportune moment for the government to have the foresight and tenacity to create a sustainable development framework for Hong Kong into the future.     

Roles of State Strategy of Adaptation to Climate Change in China

For the adverse impacts of climate change, China government should place the problem of adaptation to climate change on the agenda. It is time to institute and implement a state adaptive strategy to reduce the adverse impacts on economy, community and people＇s health and life by international cooperation and our own endeavor. A state strategy of adaptation to climate change should be closely linked with other current interrelated national strategies, and they should be supplemented and improved by each other. This paper discusses the roles of the state strategy of adaptation to climate change in the state climate change integrative strategy, the environmental protection strategy, and the sustainable development strategy in China. Furthermore, it proposes the main aims of the state adaptive strategy of China.     

A hybrid approach using AHP–TOPSIS–entropy methods for sustainable ranking of structural materials

Nowadays, many countries are looking towards sustainability as a goal because our world has limited resources and serious environmental impacts. In the construction industry, the process of sustainable selection of structural material is considered one of the keys to achieve more sustainable construction. In this paper, the theories of decision making are utilised to develop an approach for evaluation and ranking the structural materials over their total life based on sustainability criteria using multi-attribute decision-making methods. One of them is Analytical Hierarchy Process which is utilised to build the problem hierarchical structure and assign weights of the predetermined sustainable factors. The other is Technique for Order Preference by Similarity to the Ideal Solution which is utilised to rank the structural materials within both each material life cycle phase and the complete material life cycle phases. The third is the concept of entropy by Shannon to evaluate the weight factor for each phase of material life cycle. The proposed approach presents an objective, systematic and comprehensive method for the sustainable ranking of materials that links between the structural element design and the sustainable selection of materials.     

Environmental perception during rapid population growth and urbanization: a case study of Dhaka city

Dhaka city in Bangladesh has been passing through a hasty process of urbanization and population growth since the last few decades. Rapid growth of population, unplanned urbanization and industrialization in the periphery has generated pressure to the changes in land use pattern, which has also caused huge urban expansion. This expansion process is engulfing cultivated land, vegetation, wetlands and water bodies without considering their environmental impacts. This study argues that these changes and their scale of environmental impacts or sufferings are not equally distributed among the dwellers in Dhaka city. It seeks to explore variations of environmental qualities on the basis of people’s perceptions. The study finds that the dwellers in the city perceive their neighborhood environment differently, which may affect environmental qualities of the area and their sustainable management as well. Therefore, it is imperative to consider spatial variations and inequalities of environmental opportunities or sufferings in urban planning of Dhaka city.     

Integration of DFE and DFMA for the sustainable development of an automotive component

The recent developments in manufacturing organizations recognize sustainability as an important value addition for survival in the competitive scenario. The design engineers are in search of approaches for creating environmental conscious products. The purpose of this paper is to report a research carried out for ensuring sustainable product design by the integration of Design for Environment (DFE) and Design for Manufacture and Assembly (DFMA) methodologies. In this context, this paper reports a case study carried out in an automotive component. The candidate product is the charge alternator pulley. The existing pulley has been created using Computer Aided Design. Then sustainability analysis was conducted on the existing component for determining environmental impact. This is followed by the engineering analysis of the component using ANSYS. Then conceptual design changes were developed in the proposed product using DFMA concept. Then the environmental impact has been evaluated in terms of carbon footprint, energy consumption and air/water impacts on proposed product. It has been found that the optimized pulley design possesses minimal environmental impact. The result of the case study indicated that the integration of DFE and DFMA concept could initiate new developments in sustainable designs with minimal impact to the environment and it also reduces the product cost.     

Assessing agricultural land-use change in the Midlands region of KwaZulu-Natal,South Africa: application of mixed multinomial logit

On-farm tree cultivation is considered an important strategy to mitigate detrimental environmental impacts of agricultural land-use change (ALUC). In South Africa, however, little is known about farm-level incentives and constraints that govern ALUC decisions among small-scale farmers. To address this knowledge gap, this study employs a mixed multinomial logit model by using a combination of revealed and stated preference data. After correcting for endogeneity, the estimated results show that decisions about ALUC are rationally derived and driven by clear but heterogeneous preferences and trade-offs between crop productivity, food security and labour saving. The results further show that the decision to plant sugarcane is constrained by landholding, whilst farmland afforestation is negatively influenced by household size. Decisions to convert land use are also driven by the behaviour of peer groups and agro-ecological conditions. Based on these findings, important policy implications for sustainable land use are outlined.
