Das Erneuerbare-Energien-Gesetz wird zurzeit heftig diskutiert. Es hat zwar eine stark zunehmende Stromerzeugung aus erneuerbaren Energiequellen ermöglicht, wird aber mit Strompreiserhöhungen und Ineffizienzen in Verbindung gebracht. Die Autoren fordern eine grundsätzliche Anpassung der...

The amount of materials used worldwide in production and consumption increased by 56 per cent from 1995 to 2008. Using an index decomposition analysis based on the logarithmic mean divisia index, we investigate the drivers of material use, both on a global and a country scale. We exploit a panel...

Der Einsatz von Stahlschrott als Rohstoff der Stahlherstellung vermeidet Treibhausgasemissionen (THG) in erheblichem Umfang. Ambitionierte Klimaziele lassen somit einen steigenden Bedarf an Stahlschrott erwarten. Diese Studie quantifiziert plausible Bandbreiten für den Stahlschrottbedarf der...

A diverse set of tools has been developed in Industrial Ecology to tackle the problems caused by human economic activity. These instruments include Life Cycle Assessment (LCA) and Material Flow Analysis (MFA). Especially LCA is now increasingly used in policy making. Design and Evaluation of...

The German electricity market is changing fundamentally as renewable energy replaces conventional sources. Simultaneously, regional imbalances between generation and consumption are appearing. The authors sketch a new market design for the German electricity market, jointly taking into account...

Compared to oil and gas, metals have been rather a side issue in the economic analysis of natural resources in the last decades. However, in the recent past we saw an increase of interest in the topic, mainly driven by the heated discussion about critical metals. Rare Earth Elements (REE) are...

Rare Earths are a group of 17 metals which were presumably unknown to the vast majority of people until very recently. The combination of growing demand and tightened export restriction by China, which holds almost monopolistic power in their supply, has led to massive price increase in 2011....

This report presents the Basic WIOD CGE model. The model represents the first implementation of the World Input-Output Database (WIOD) into the CGE framework and is tailored to provide a maximum fit with WIOD data. The model is specifically designed such that it can serve as the basis for...

Using an index decomposition analysis based on the logarithmic mean divisia index, we investigate the drivers of material use, both on a global and a country scale. We exploit a panel...

This paper presents the METal ResOurces (METRO) model, a partial equilibrium model tailored for metal markets. It allows for a disaggregated representation of the mining sector and endogenous investment in extractive capacities. It can be calibrated to a large number of metal markets. Rare Earth...
