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.     

河北省构建低碳消费模式的法律途径研究

构建低碳消费模式,法律规制十分必要。河北省低碳消费法律规制步伐虽然已启动,但依然面临着缺乏统一法律体系,对企业相应行为规制和保障不力,对消费者低碳消费关注不够以及执法和司法体制不健全等诸多问题。在此背景下,为在河北省构建低碳消费模式,笔者借鉴国外先进做法,提出了在立法层面上构建统一的低碳消费法律体系,将消费者的环境权利和环境义务纳入法律框架;执法层面上完善执法机构,加强执法力度,健全执法机制,加大宣传力度;司法层面上提高认识,完善机构,健全司法程序;社会层面上在政府引导下,要求企业、非政府组织及消费者个人广泛参与的法律对策。     

New concepts in product use for sustainable consumption

The paper presents the main results of a recent study on sustainable use of products. It reveals that strategies of use intensification and useful life extension are environmentally beneficial. Moreover, analysis of household washing and winter sports illustrated that successful implementation of sustainable use patterns occurs as a shift of use regimes. Such regimes are the result of a complex interplay of supply and demand side factors, relationship among actors, technical trajectories, organisational structures etc. One decisive factor is the presence of strategic players, so called “change agents”. In addition, four user types have been identified in a representative survey (“ownership-oriented”, “open-minded”, “consumption-oriented”, “low interest”) to which use intensification and useful life extension can be targeted.     

The role of business in sustainable consumption

This paper explores the role of the business community in promoting sustainable consumption. While businesses play an important role in shaping social trends, including the growth of material consumption, allegations that individual corporations wield excessive power may have been overstated. Most of the time corporations are simply playing by the rules and culture of the market.Businesses have mostly assumed that their contribution to sustainability lies in improving eco-efficiency—staying within the current business framework. But sustainable consumption will require wider change, including shifts in the incentives that shape the actions of businesses and others, and a change in the culture that underlies market expectations. Firms, governments, the media and civil society may need to enter a dialogue together to develop a new story about the nature of prosperity and the role of the business community in promoting it. The initiative is most likely to come from civil society.

The pathway to a sustainable industrial society – initiative of the Research Institute for Sustainability Science (RISS) at Osaka University

While it is widely known that sustainable development is the only sound and viable pathway for humankind’s future, its attainment remains elusive despite intensive efforts and some successes. The current industrial society approach based on product and process innovation in a variety of fields is not providing the expected results in addressing this important issue. In an attempt to carry out this unavoidable task, Osaka University’s Research Institute for Sustainability Science (RISS) introduces an integral and dynamic innovation system where technology plays a key role in fulfilling societal functions. This innovation system adopts a highly solution-driven approach that makes use of backcasting techniques based on long-term visions and mid-term strategic goals. Since technology management is the key to propelling effective innovation towards sustainability, we propose a technology transition management through the interaction of technology push, demand pull and institutional design, along with eight transition principles. RISS will develop this innovation system based on these three components and through the design of dynamic scenarios and their roadmaps.     

Optimum Supportable Global Population: Water Accounting and Dietary Considerations

In this paper we develop a novel, comprehensive method for estimating the global human carrying capacity in reference to food production factors and levels of food consumption. Other important interrelated dimensions of carrying capacity such as energy, non-renewable resources, and ecology are not considered here and offer opportunities for future work. Use of grain production (rain-fed/irrigated), animal product production (grazing/factory farm), diet pattern (grain/animal products), and a novel water accounting method (demand/supply) based on actual water consumption and not on withdrawal, help resolve uncertainties to find better estimates. Current Western European food consumption is used as a goal for the entire world. Then the carrying capacity lies in the range of 4.5–4.7 billion but requiring agricultural water use increase by 450–530% to 4725–5480 km³, the range based on different estimates of available water. The cost of trapping and conveying such water, will run 4.5–13.5 trillion over 50 years requiring an annual spending increase of 150–400%, straining the developing world where most of the population increase is expected. We reconfirm estimates in the literature using a dynamic model. ‘Corner scenarios’ with extreme optimistic assumptions were analyzed using the reasoning support software system GLOBESIGHT. With a hypothetical scenario with a mainly vegetarian diet (grazing only with 5% animal product), the carrying capacity can be as high as 14 billion. Ecological deterioration that surely accompanies such a population increase would negatively impact sustainable population. Using our approach the impact of ecological damage could be studied. Inter- and intra-regional inequities are other considerations that need to be studied.     

Effect analysis of carbon trading on Economy-Energy-Environment system and calculation of reasonable carbon price intervals

This paper constructs a 4-lier computable general equilibrium model which includes such modules as modeling carbon emission constraints and carbon trading(CT),and incorporates the cost of carbon emissions into constant elasticity of substitute production function.Under scenario settings under different carbon abatement targets,based on 2007 national social accounting matrix and related statistical data about energy consumption and carbon emission,effects on economic outputs,energy consumption,and carbon abatement are estimated and analyzed at both macro and sector level.By calculating selected novel indicators that compromise between macroeconomic opportunity cost and achievable carbon abatement,reasonable carbon price intervals are given for enhancing the robustness and liquidity of carbon market.Further,by decomposition and share-weighted methods,expected carbon abatement and energy price are measured and analyzed in details.Some results are meaningful for fundamental design of the future carbon market.Given constant energy utilization and carbon abatement technologies at the macro level,the higher the carbon price the more actual carbon abatement;the more gross domestic product loss,the less energy consumption.Accwding to the overall situation estimated for 2007 in China,the advice given is to introduce a carbon abatement target rate(R_c)of-10%,which is helpful to make carbon market stable against unexpected carbon price shocks between[6.9,35]/tC with less economic loss.According to Kaya decomposition,after introduction of carbon pricing,carbon abatement is mainly contributed by the effects of energy intensity(EI)and technical progress.Further,CT may help reduce energy consumption and induce transformation to a low-carbon energy structure.At the sector level,the introduction of CT could induce economic recession in all sectors,especially energy.However,the overall economic structure remains unchanged to some extent.CT will help reduce energy consumption in all sectors,especially energy.Overall utilization costs of the energy composite can be divided in two,market price and carbonrelated costs.Carbon-related costs mainly contribute to variation in the utilization cos of the energy composite;carbon pricing may help non-energy sectors achieve sufficient carbon abatement by pushing up energy utilization cost.However,despite achievable carbon abatement by the energy sector being relatively high,induced by carbon pricing,there is still significant potential for other incentive policies to stimulate further abatement,such as energy resources taxation and transportation fuel taxation,especially in the sectors of coal and transportation.Finally,some advice is proposed in regard to policy decisions and further research.     

Rural households’ livelihoods diversification through termite utilization in depressed region of Zimbabwe

This study sought to examine the utility of termites to rural households in depressed regions of Bikita, Zimbabwe. Colonialism and its spread of European culture had viewed entomophagy with contempt resulting in reduced utilization and consumption of termites in most colonies. In our quest to understand how people in depressed regions utilized termites, both quantitative and qualitative methodologies were employed. Questionnaires and in-depth interviews were used to gather data during field work. Purposive and snowball sampling techniques were used in recruiting respondents. Excel and content analysis were used in data presentation and analysis. Results revealed that dampwood and drywood termites are climatic indicators for the rural communal farmers, a low-cost technology in weather forecasting. Subterrain and mold builders provide manure, relish, and are medicinal in nature. They are traded for income generation, and as for the poor, harvesting, processing, storage, and marketing is cost effective. Though considered nostalgic foods, most respondents highlighted that selling termites complimented other off-farm livelihood activities. Termite consumption and utilization provide a sustainable way for livelihood diversification in depressed regions and has partly addressed problems of food insecurity.
