TY - JOUR A1 - Spangenberg, J. H. A1 - Lorek, S. T1 - Environmentally sustainable household consumption: from aggregate environmental pressures to priority fields of action JF - Ecological Economics N2 - Unsustainable consumption patterns of the North (or rather of the global affluent consumers class) have been identified by Agenda 21 as one of the key driving forces behind the unsustainable development. However, neither accounting based on the system of national accounts SNA nor household economics provide the proper instruments to assess the environmental impact of household decision making. Eco-efficiency assessments as familiar in the business sector provide no appropriate tool for households. As an alternative an environmental space based assessment scheme is suggested covering the major pressures on the environment caused by household decisions. The methodology is used twice: once to analyse the environmental relevance of the main activity clusters of household consumption and once to identify the dominant acts of consumption within each cluster. The latter provide the basis for deriving environmental performance indicators. A rough analysis of household influence potentials permits to identify housing, eating and mobility as the three priority fields for action for minimising the environmental impact of households. Extending the influence analysis actor matrixes are derived allocating influence and thus responsibility for environmental pressures to different groups of economic agents.

H. A1 - Lorek, S. T1 - Indicators for environmentally sustainable household consumption JF - Int. J. Sustainable Development N2 - The objective of this paper is to identify those areas of consumption, in which private households can make significant contributions to environmental sustainability, and to present a transparent and comprehensive set of indicators for them. The analysis of the environmental impacts of households focuses on consumption clusters that permit to depict different life spheres of private households. Two criteria guided the investigation of the relevance of these clusters: · The significance of the consumption cluster, and · The potential influence of households. Resource consumption was chosen as simplified, but reliable representation of environmental pressure dynamics. Growing resource consumption goes together with growing environmental pressures and vice versa, although not necessarily proportionally. The key resources analysed are energy and material consumption, and land use. Based on this analysis, three priority fields for action by households were identified: construction and housing, food/nutrition and transport (in this order). All other consumption clusters can be considered environmentally marginal, providing combined saving potentials of less than 10% of the total resource consumption. Finally, from description of the respective roles of actors based on anecdotal evidence a semi-quantitative "actor matrix" is presented indicating the relative influence of different actors per consumption cluster.

A1 - Lorek, S. T1 - Sustainable Consumption Governance in a Globalizing World JF - Global Environmental Politics 2:1, February 2002 N2 - The influence of globalization on the sustainability of consumption is a frequent topic in academic and political debates. Despite this, the scientific understanding of this influence and, even more so, of the consequences for governance strategies in pursuit of sustainable consumption are still weak. In this paper, we therefore inquire into the specific channels of the influence of globalization on the sustainability of consumption. Based on our analysis, we develop guidelines for sustainable consumption governance.

Therefore to be effective, efficiency measures have to be embedded in a concept of sufficiency which strives for limits and absolute reduction of energy consumption. While the sufficiency concept is not new, it only recently gained attention in the field of housing. This paper provides a basis for broader and more informed debates in policy and research on the potential of sufficiency considerations to contribute to the overall reduction of energy consumption in the residential sector. It recommends shifting the attention from energy consumption of buildings towards a concept of sustainable homes in which e.g. the size of the living area plays a crucial role. A further important aspect is the possibility to fulfil other basic needs like the provision with food, recreation and social contacts in the nearby environment. The paper describes first examples of housing projects guided by sufficiency criteria, depicts the potential roles of different actor groups and points towards some general policy recommendations.

The Theory of Planned Behaviour TPB and Social Practice Theory SPT offer different views on consumer behaviour, and on ways to change it. This paper briefly describes the challenges, discusses the applicability of both theories and their meaningfulness for policy recommendations. We suggest an approach combining results of both bodies of theory, complemented by ideas from political economy, to substantiate the Prism of Sustainable Consumption we introduce as a heuristic sufficiency policy tool. It is useful to identify affordability criteria for change in each dimension, as the basis for deriving suggestions for effective policy interventions. We conclude that (i) effective interventions are possible, (ii) they have to address several dimensions of affordability simultaneously, and (iii) the sufficiency policy space prism can be a useful tool in structuring planned interventions.

Moreover, in the face of demographic change and a growing global population, sus-tainability problems arising from food systems will likely become more serious in the future. For example, agricultural production must deal with the impacts of climate change, increasingly challenging land-use conflicts, and rising health and social costs on both individual and societal levels. The unsustainability of current arrangements arises from the industrialization and globalization of agriculture and food processing, the shift of consumption patterns toward more dietary animal protein, the emergence of modern food styles that entail heavily processed products, the growing gap on a global scale between rich and poor, and the paradoxical lack of food security amid an abundance of food. These factors are attributable to national and international policies and regulations, as well as to prevalent business prac-tices and, in particular, consumers’ values and habits. The most effective ways for affluent societies to reduce the environmental impact of their diets are to reduce consumption of meat and dairy products (especially beef), to favor organic fruits and vegetables, and to avoid goods that have been transported by air on both individual and institu-tional levels (e.g., public procurement, public catering). In examining the unsustainability of the current food system this article reviews the pertinent literature to derive a working definition of sustainable food consumption, outlines the major issues and impacts of current food-consumption practices, and discusses various policy interventions, including information-based instruments, market-based initiatives, direct regulations, and “nudges.” It concludes with a call for integrative, cross-sectoral, and population-wide policies that address the full range of drivers of unsustainable food production and consumption.
