An input-output approach to analyse the Total Material Requirement (TMR) of national economies
(1999)
The adoption of the Kyoto Protocol in December 1997 was a major achievement in the endeavour to tackle the problem of global climate change at the dawn of the 21st century. After many years of involvement in the negotiation process, the book's two internationally recognised authors now offer the international community a firsthand and inside perspective of the debate on the Kyoto Protocol. The book provides a comprehensive scholarly analysis of the history and content of the Protocol itself as well as of the economic, political and legal implications of its implementation. It also presents a perspective for the further development of the climate regime. These important features make this book an indispensable working tool for policy makers, negotiators, academics and all those actively involved and interested in climate change issues in both the developed and developing world.

"Planet Dialectics" explores the ambivalences and ironies, the controversies and conflicts that pervade the terrain of global environmental politics. Most inquiries turn around one nagging suspicion: that the Western development model is at odds with both the quest for justice among the world's people and the aspiration to reconcile humanity and nature. By any stretch of imagination, it will not be possible that all citizens of the world will share in the fossil fuel-based, money-driven development model - with all its attendant paraphernalia - that has come to hold sway in the world today. The biosphere, as we know it, may give in. Against this background, the book probes Western-style development, examines its hidden assumptions, its glamour, its obsessions and the hopes it holds out for a better life. Moreover, it examines under various aspects if sustainability (truly conceived) - comprising both ecology and social fairness - is incompatible with the worldwide rule of economism. And finally, it suggests ways to leave conventional modernity behind by creating sophisticated but moderate-impact technologies, redirecting relentless accumulation, and appreciating ways of living that are simpler in means, but richer in ends.

This book on Green Budget Reforms (GBR) provides comprehensive insight into how forerunner countries such as Denmark, the Netherlands, Norway, Sweden and Switzerland, but also Hungary and Poland, have designed and taken first steps toward GBR, with emphasis on Ecological Tax Reform (ETR). The book covers the proceedings of an international seminar held in Slovenia with contributions from economists of the European Commission, the OECD, finance ministries and researchers. It also includes the first comprehensive case study of Slovenia, demonstrating the unique opportunities for GBR in Central and Eastern European Countries in particular. The book is for policy makers, consultants, lecturers, and scientists who wish to make and measure progress in sustainable development. Readers can choose from a range of market-based instruments applied in various countries and adapt them according to the requirements of their countries.
It is not the scarcity of resources that constitutes environmental problems, but their use, the physical throughput of our economies. Material flows are a proxy for the totality of the unspecific environmental risks from human activities. As a strategic goal, an increase of the life-cycle-wide resource productivity by a factor 10 is suggested, including the materials bought and sold and the not-valued materials: we have to take into account the product itself and its "ecological rucksack". Material flows are best measured at the input side of the economy, where their number as well as the number of entry gates is limited. Thus here regulation and economic incentives can work more efficiently and less bureaucratically than today. The material intensity of products and services can be expressed as MIPS, the material input per unit of service, and as TMR, the total material requirement on the macro level, an important element in physical input–output tables.
In this paper the results of an analysis of the material intensity of advanced composite materials are presented. The analysis is based on the MIPS-concept of the Wuppertal Institute which allows the calculation of the overall material intensity of products and services. It can be shown that the production of one kg of E-Glass fibers is connected with the consumption of 6.2 kg materials, 95 kg water and 2.1 kg oxygen which is of similar size compared to the inputs required in steel production. Material inputs required to produce one kg of p-aramid are 37 kg of materials and 19.6 kg air. Values for carbon fibers are even higher yielding to 61.1 kg of abiotic materials and 33.1 kg of air. Similarly, the production of epoxy resins is connected with larger material flows than the production of polyester resins. Of core materials, inputs per kg for PVCfoam exceed those in PUR-foam production by a factor of 1.4 in water to 2.3 in abiotic material consumption. However, ecologically decisive are not the inputs per kg but the material input per service unit. Therefore, the material input per service unit computed for the body of a passenger ship and a robot arm are compared with alternative steel and aluminium versions. Both examples show that in the case of significant inputs during the user phase of products, even a more material intensive investment in the production phase can yield significant ecological benefits over the whole life-cycle compared to metal versions. Improvements can easily reach a factor of two albeit significant potential for engine optimizations have still been neglected. Results already include the actual recycling quota of metals whereas for composites only virgin material has been calculated as any form of real recycling does not actually exist but only certain types of downrecycling. Of those treatment options, first material recycling and second the use in blast furnaces would lead to better results in resource productivity than incineration and landfills. The paper finally draws some conclusions about the potential advantages of material substitution in the automotive industry. Due to the rather short real operation time of cars during their user phase - around six months - an investment in advanced composite materials in car production only results in a significant improvement of the overall eco-efficiency of cars if it allows a substantial weight reduction of the overall vehicle.

Für Ernst Ulrich von Weizsäcker steht fest, daß das nächste Jahrhundert das Jahrhundert der Umwelt sein wird. Wenn die Menschheit überleben will, muß dem Schutz der Natur höchste Priorität eingeräumt werden. Von Weizsäcker entwirft ein neues Leitbild für zukunftsfähiges Wirtschaften und demonstriert anhand der weltweiten Projekte der EXPO 2000 - vom abwasserfreien Haus über die Solarsiedlung Freiburg bis zum Rottaler Modell für Strom aus der Biotonne -, daß Öko-Effizienz nicht mehr reine Theorie ist, sondern bereits umgesetzt wird: So könnte eine Zukunft aussehen, in der weniger Naturressourcen verbraucht werden, ohne daß der Lebenssstandard sinkt.
Namhafte Autoren aus führenden nicht-staatlichen Organisationen ergänzen den Band um faszinierende Visionen, wie eine zukunftsfähige Welt zu gestalten ist. Sie beschreiben u.a. Szenarien für Nachhaltigkeit in Europa und Lateinamerika, fordern einen globalen Technologiepakt und fragen nach der Rolle der Entwicklungsländer im Globalisierungsprozeß.
The discussion of sustainable development focused attention on new environmental goals and raised the issue of improving resource productivity. A first step towards sustainability would be to slow-down and reduce the man-induced movements of materials: this is the focus of dematerialization approach which emphasizes what socialist countries used to neglect most – minimizing the use of scarce input factors. This paper applies the dematerialization approach to the discussion on sustainable development in central and eastern Europe. In the early 1990s all countries in eastern Europe have developed new environmental programs which mainly focus on reducing pollution. Environmental strategies focusing on reducing emissions are important but not sufficient for reaching sustainability. A new orientation in the environmental policy in the young market economies is required. Dematerialization approach can be a new option for environmental policy in central and eastern Europe. Dematerialization requires a mix of instruments. Important role can be played by an ecological fiscal reform which covers ecological tax reform and the restructuring of subsidies.

Ökoeffizienz ist die Grundlage eines zukunftsfähigen Managements, dessen Ziel es ist, Ökonomie und Ökologie zu vereinen. Ernst Ulrich von Weizsäcker und Jan-Dirk Seiler-Hausmann zeigen, daß diese Kombination den Unternehmen in Zukunft sogar mehr Gewinn bringen kann als herkömmliche Unternehmensführung.
