This paper presents a new household-level methodology for transition towards sustainability. The methodology includes measuring the resource use of households on a micro level, testing relevant measures towards a one-planet resource use, and developing mainstreaming options in co-operation with households and providers of services, products, and infrastructures. We use the MIPS (Material Input Per unit of Service) method to calculate the use of natural resources and concentrate on the material footprint as an aggregated indicator for the overall use of material resources. With HST (Household-level Sustainability Transition) methodology, we extend the material footprint methodology from just measuring household resource use to developing visions, conducting experiments, as well as learning and upscaling, all of which contribute to the whole Transition-Enabling Cycle. Results from the first application of the HST methodology on five households in Jyväskylä, Finland, show that it is possible to achieve a significantly more sustainable level of consumption by a relatively few changes in everyday living. Achieving a one-planet use of material resources, however, also requires systemic changes.
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.
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.
