This thesis justifies and develops a sustainable level of Lifestyle Material Footprint (LMF) as a benchmark for designing sustainable lifestyles. It shows the application of the benchmark in a Household-level Sustainability Transition method and presents a framework for inspiring design solutions towards a Design for One Planet (Df1P).
The thesis shows how the Material Input per unit of Service (MIPS) concept has developed from product orientation to the application to household consumption and from technically-focused measurement into an integral part of methods for designing one-planet lifestyles and supporting solutions. This provides both an advanced application of the concept and its opening to new purposes and users.
The core of the thesis is the suggestion of a sustainable material footprint benchmark of 8 tonnes per person per year as a resource cap target for household consumption in Finland, an 80% (factor 5) reduction from present average. The 8 tonnes benchmark opens the possibility for a target-oriented, planned reduction of LMFs by target-setting, experimenting and up-scaling of sustainable solutions. The method enabled the participating households to perform footprint reductions of 26–54% during the one-month experiment phase. Notable footprint reductions are thus possible even in the short term, which is an important message to other households and other actors in society. Calculating households' LMFs makes visible the structures underlying household consumption and the need for change not only in household consumption but also in the supply of products, services and infrastructure, and thus systemic changes initiated by others than households.
The orientation framework of Df1P suggests measures that could be promoted by means of design, and structures them in a matrix incorporating priority action areas in the fields of housing, nutrition and mobility, and the domains of product design, service design, infrastructure planning and communication design. Mainstreaming sustainable lifestyles will potentially require a new design culture, but at least significant efforts in product design, service design and infrastructure planning as well as in making sustainable solutions attractive to consumers and disrupting existing routines. The more technology and infrastructure can be integrated into this change, the more space will be left for individual diversity in achieving sustainable household consumption. The orientation framework could provide a first step towards Df1P practice by inspiring designers to integrate the recognition of the planetary boundaries into their work.
The paper presents a case study of applying crowdsourcing to library deliveries. The trial was conducted in the city of Jyväskylä in Finland as part of the Resource Wise Communities program funded by The Finnish Innovation Fund Sitra. The city has a population of 120 000 inhabitants and is facing the shut-down of half of the public libraries in order to adapt its economy to lowered revenues and compulsory cost savings. The assumption was that the level of service for customers not able to settle for e-books would be lowered and/or customers would have to travel longer distances. However, a research pilot was carried out where - instead of lowering the level of service in the area - books and other library media were delivered to customers' homes by utilizing a novel crowdsourced delivery service called PiggyBaggy.
Crowdsourced delivery means that citizens deliver goods to each other along their way. Ideally, the deliveries would be made with minimal detour, along the way, thus maximizing the reduction in natural resource use and related environmental impacts from the transport. However, the transport fuel forms only one part of the overall footprint and in practice rebound effects such as drivers travelling longer distances motivated by monetary compensation, can reduce the targeted environmental improvement.
The objective of our study was to investigate whether an existing consumer service, in this case the library public service, can adopt crowdsourced deliveries quickly from scratch, and to whether consumers participate in the deliveries in a way that has real sustainability benefits. Despite prevailing regulative challenges, the study found that existing library deliveries can be successfully crowdsourced. Each crowdsourced delivery reduced an average of 1.6 kilometers driven by car, despite 80 percent of the deliveries being made within less than a five-kilometer distance. Mobility related footprint reduction potential for Finland is also estimated.
Ressourceneffizienzpotenziale in der Lebensmittelproduktion an den Beispielen Obst, Gemüse und Fisch
(2013)
Ressourceneffizienz verspricht geringere Materialkosten, Importunabhängigkeit und geringere Umweltbelastungen. Die Einspareffekte lassen sich auf vielfältige Art erreichen: Sei es durch Einsatz neuer Technologien, Optimierung bestehender Technologien oder Strategien, die Produktion und Konsum aufgreifen. Das Buch zeigt anhand von 18 Beispielen, wie sich Ressourceneffizienz erfolgreich in Deutschland umsetzen lässt und welche Einspareffekte zu erzielen sind.
A decent, or sufficient, lifestyle is largely considered an important objective in terms of a sustainable future. However, there can be strongly varying definitions of what a decent lifestyle means. From a social sustainability point of view, a decent lifestyle can be defined as the minimum level of consumption ensuring an acceptable quality of life. From an ecological sustainability point of view, a decent lifestyle can be defined as a lifestyle that does not exceed the carrying capacity of nature in terms of natural resource use. The paper presents results of a study on the natural resource use of 18 single households belonging to the lowest income decile in Finland. The yearly "material footprint" of each household was calculated on the basis of the data gathered in a questionnaire and two interviews. The results show that the natural resource use of the participating households was lower than the one of the average consumer. Furthermore, 12 of 18 households had a smaller material footprint than the "decent minimum" reference budget defined by a consumer panel. However, the resource use of all the households and lifestyles studied is still higher than long-term ecological sustainability would require. The paper concludes that the material footprint is a suitable approach for defining and measuring a decent lifestyle and provides valuable information on how to dematerialize societies towards sustainability.
Designguide background
(2013)
Current well-being research often overlooks human dependency on natural resources and undervalues the way environmental impacts affect human activities. This article argues that the capability approach provides an applicable framework for inquiring into ecologically sustainable well-being. Therefore, this pilot study aims to develop a research method for integrating the measurement of natural resource use with capability-based well-being research. Semi-structured interviews were carried out with 18 Finnish minimum income receivers and their natural resource use (material footprints) was measured in five central functionings by using the Material Input Per Unit of Service (MIPS) method. The connections between capabilities, functionings and material footprints are interpreted from a person-centered perspective in order to explain the individual variety in material footprints. The results show that the material footprints of minimum income receivers are smaller than with an average Finn but they still exceed what is estimated to be an ecologically sustainable level of natural resource use.
The field of nutrition is facing numerous social, ecological and economic challenges in the coming decades. The food industry belongs to the most significant economic sectors worldwide and the increasing population of 9 billion in 2050 will cause a growing demand on food. So far, changing lifestyles, especially the global rising consumption of meat and dairy products are increasing environmental damage. Moreover our health and wellbeing are the direct result of healthy or unhealthy nourishment and influence follow-up indicators like individual and public health, the expense of the health sector and work productivity.
The material footprint is a tool to measure and optimize the resource consumption of both products and their ingredients and the production processes along the whole value chain. It covers the whole life cycle of the products, from the extraction of raw materials to the processing industry, distribution, consumption, recycling, and disposal. In order to decrease resource consumption to a level in line with the planetary boundaries, the material footprint of household consumption should achieve a level of six to eight tonnes per capita in a year by 2050. This means a reduction in natural resource consumption by a factor of 5 to 10 in Western European countries. In order to ensure a decent lifestyle for all people in 2050, also the material footprint of nutrition has to be reduced significantly by 2050.
The paper shows the relevance and role of nutrition in the overall material footprint of households on the basis of existing studies on the overall resource consumption caused by household consumption. Quantified meal and diet examples are given. It also discusses the causes of food waste and raises the question how a reduction of food waste is possible and can help decreasing the resource consumption in the food sector.
