Klimawandel, Hungerkrise, Rohstoffknappheit und Naturzerstörung stehen auf der internationalen Tagesordnung. Dennoch geht in der Politik, in der Wirtschaft und im Alltag Vieles weiter wie bisher: Für Flughäfen werden neue Start- und Landebahnen geplant, neue Kohlekraftwerke sollen gebaut werden und Heizpilze sprießen aus dem Boden. Im Zweifelsfalle sind der Politik die Ankurbelung der Nachfrage und die Interessen der Autoindustrie wichtiger als der Klimaschutz. Und selbstverständlich sollen Lebensmittel, T-Shirt und Turnschuhe wenig kosten. Armut in Entwicklungsländern hin, Umweltverschmutzung in Schwellenländern her. Die Notwendigkeit einer nachhaltigen Politik wird vielfach beschworen - und ungebrochen dem Wirtschaftswachstum Vorrang eingeräumt.
Der Klimawandel ruft nach nichts weniger als einem Zivilisationswandel. Das war die Ausgangslage für ein interdisziplinär angelegtes Forschungsprojekt des Wuppertal Instituts unter der Leitung von Prof. Dr. Wolfgang Sachs. Es wurde im Sinne einer Zwischenbilanz gefragt, "ist Deutschland zukunftsfähiger geworden und wie haben sich die Bedingungen mit der Globalisierung verändert?".
Economic performance of a country is generally being measured through GDP (Gross Domestic Product), a variable that has also become the de facto universal metric for "standards of living". However, GDP does not properly account for social and environmental costs and benefits. It is also difficult to achieve sustainable decision-making aiming at sustainable progress and well-being if welfare is being considered from a purely financial point of view. The study highlights the benefits and some of the shortcomings of GDP. It serves as a helpful and practicable instrument for monetary and fiscal policies. The real problem presumably is that GDP growth is too often confused with (sustainable) welfare growth in people's minds. While there certainly is a correlation between the two, this study shows that this is a highly conditional correlation, void of substantial causality for GDP levels observable in the European Union. In order to be able to assess people's well-being and general sustainable development in the sense of sustainability, an alternative instrument going beyond GDP is necessary. Using so called SWOT analyses, several alternative progress indicators have been assessed in the context of this study. On the one hand it was analysed how far ecological and social factors can be integrated in the GDP measurements. Thereby difficulties arose then trying to monetise these factors. As a further possibility indicators were analysed which are to replace GDP as a whole. The category supplementing GDP seems to be the most realistic and acceptable option for going beyond GDP. Within this approach, GDP is being complemented with additional environmental and/or social information. In order to make this kind of solution feasible the study claims the establishment of an overarching and transparent indicator system for improving economic decision-making in support of sustainable development.
Material flows induced by national economies can be regarded as indirect pressure indicators for environmental degradation. Economy-wide material flow analysis and indicators have been designed to monitor material and energy flows at the macroeconomic level and to provide indicators, which could contribute to management of resourceuse and output emission flows from both economic, environmental and broader sustainability points of view. These indicators can serve various purposes including monitoring the material basis of national economies and related environmental pressures, assessment of the material and resource productivity and monitoring the implications of trade and globalisation.
The main part of this paper compares the material and resourceuse of the Czech Republic, Germany and the EU-15 by means of DMI and TMR indicators over the period of 1991–2004 (1991–2000 for EU-15). At the aggregate level both indicators in all three economies do not show any clear decreasing or increasing trends over the period considered. This means that environmental pressure related to use of materials for production and consumption purposes remains rather stable. All the economies however, recorded an increase in the efficiency of transforming the material/resource inputs into economic output. The analysis further revealed that most of the dynamics of DMI and TMR in the Czech Republic tended towards a higher similarity with Germany and the EU-15. In the future, further decreases in DMI as well as in TMR of fossils fuels might be expected in the Czech Republic, which could be counteracted by increase in DMI and TMR of metal ores/metal resources and non-metallic minerals/non-metallic resources. The future development of total DMI, TMR and material/resource intensity in both the Czech Republic and Germany will depend on further shifts to less material intensive industries and services and on increasing material efficiency in production and consumption of particular products. This is not only a technological, but also a social challenge, as there are barriers in current mode of governance and in shaping of current economic and social systems to do so.
