The concept Material Input per Service Unit (MIPS) was developed 20 years ago as a measure for the overall natural resource use of products and services. The material intensity analysis is used to calculate the material footprint of any economic activities in production and consumption. Environmental assessment has developed extensive databases for life cycle inventories, which can additionally be adopted for material intensity analysis. Based on practical experience in measuring material footprints on the micro level, this paper presents the current state of research and methodology development: it shows the international discussions on the importance of accounting methodologies to measure progress in resource efficiency. The MIPS approach is presented and its micro level application for assessing value chains, supporting business management, and operationalizing sustainability strategies is discussed. Linkages to output-oriented Life Cycle Assessment as well as to Material Flow Analysis (MFA) at the macro level are pointed out. Finally we come to the conclusion that the MIPS approach provides relevant knowledge on resource and energy input at the micro level for fact-based decision-making in science, policy, business, and consumption.
Article 0 Reads 25 Citations Eight Tons of Material Footprint—Suggestion for a Resource Cap for Household Consumption in Finland Michael Lettenmeier, Christa Liedtke, Holger Rohn Published: 09 July 2014

The paper suggests a sustainable material footprint of eight tons, per person, in a year as a resource cap target for household consumption in Finland. This means an 80% (factor 5) reduction from the present Finnish average. The material footprint is used as a synonym to the Total Material Requirement (TMR) calculated for products and activities. The paper suggests how to allocate the sustainable material footprint to different consumption components on the basis of earlier household studies, as well as other studies, on the material intensity of products, services, and infrastructures. It analyzes requirements, opportunities, and challenges for future developments in technology and lifestyle, also taking into account that future lifestyles are supposed to show a high degree of diversity. The targets and approaches are discussed for the consumption components of nutrition, housing, household goods, mobility, leisure activities, and other purposes. The paper states that a sustainable level of natural resource use by households is achievable and it can be roughly allocated to different consumption components in order to illustrate the need for a change in lifestyles. While the absolute material footprint of all the consumption components will have to decrease, the relative share of nutrition, the most basic human need, in the total material footprint is expected to rise, whereas much smaller shares than at present are proposed for housing and especially mobility. For reducing material resource use to the sustainable level suggested, both social innovations, and technological developments are required.

The article assesses the material footprints of households living on a minimum amount of social benefits in Finland and discusses the consequences in terms of ecological and social sustainability. The data were collected using interviews and a questionnaire on the consumption patterns of 18 single households. The results are compared to a study on households with varying income levels, to average consumption patterns and to decent minimum reference budgets. The low-income households have lower material footprints than average and most of the material footprints are below the socially sustainable level of consumption, which is based on decent minimum reference budgets. However, the amount of resources used by most of the households studied here is still at least double that required for ecological sustainability. The simultaneous existence of both deprivation and overconsumption requires measures from both politicians and companies to make consumption sustainable. For example, both adequate housing and economic mobility need to be addressed. Measures to improve the social sustainability of low-income households should target reducing the material footprints of more affluent households. Furthermore, the concept of what constitutes a decent life should be understood more universally than on the basis of standards of material consumption.
