TL;DR: The TEM-model can be regarded as a useful tool to implement and verify a technical Joint-Implementation Program, where its necessary fund is represented by the non-empty core of the analyzed game.
Abstract: The presented TEM-model describes the economical interaction between several actors (players) which intend to minimize their emissions (E
i) caused by technologies (T
i) by means of expenditures of money (M
i) or financial means, respectively. The index stands for the i-th player, i=1, … ,n. The players are linked by technical cooperations and the market, which expresses itself in the nonlinear time-discrete dynamics of the Technology-Emissions-Means-model, in short: TEM-model. In the sense of environmental protection, the aim is to reach a state which is mentioned in Kyoto Protocol by choosing the control parameters such that the emissions of each player become minimized. The focal point is the realization of the necessary optimal control parameters via a played cost game, which is determined by the way of cooperation of the actors. In application to the work of Leitmann, but not regarding solution sets as feasible sets, the τ-value of Tijs [13] is taken as a control parameter. This leads to a new class of problems in the area of 1-convex games. We want to solve the problem for a special case. With this solution a reasonable model for a Joint-Implementation process is developed, where its necessary fund is represented by the non-empty core of the analyzed game. Steering with parameters of this feasible set, the TEM-model can be regarded as a useful tool to implement and verify a technical Joint-Implementation Program. For the necessary data is given to the Clearing House, we are able to compare the numerical results with real world phenomena.

TL;DR: In this article, the Kyoto Game is introduced and a first approach to Joint International Emissions Trading (JET) is given, which is an international program which intends to strenghten international cooperations between enterprises in order to reduce CO 2-emissions.
Abstract: The conferences of Rio de Janeiro 1992 and Kyoto 1997 demand for new economic instruments which have a focus on environmental protection in the macro and micro economy. An important economic tool being part of the treaty of Kyoto in that area is Joint-Implementation. It is an international program which intends to strenghten international cooperations between enterprises in order to reduce CO 2-emissions. A sustainable development can only be guaranteed if the instrument is embedded into an optimal energy management. For that reason, the Technology-Emissions-Means (TEM) model was developed, giving the possibility to simulate such an extraordinary market situation. In this paper, the Kyoto Game is introduced and a first approach to Joint International Emissions Trading (JET) is given.

Abstract: This volume collects the extended abstracts of the 36 contributions that have been selected for presentation at the 1st CologneTwenteWorkshop on Graphs and Combinatorial Optimization 6-8 June, 2001 Center of Applied Computer Science University of Cologne Cologne, Germany The CologneTwenteWorkshop on graphs and combinatorial optimization is organized biennially at the Department of Mathematics at the University of Cologne and at the Faculty of Mathematical Sciences at the University of Twente. There are no “main speakers” and young researchers are particularly encouraged to discuss their work on algorithmic as well as structural aspects of graphs and combinatorial optimization problems. As this volume demonstrates, research in this area is lively and successful. The local organizers want to thank the members of the programming committee J. Fonlupt (Paris) M. Junger (Cologne) H.J. Promel (Berlin) C. Thomassen (Copenhagen) G. Woeginger (Graz) for their help in setting up such an attractive program. An additional special volume of Discrete Applied Mathematics devoted to the 1st CologneTwenteWorkshop will be prepared. This volume will contain full-length versions of presentations at and results of the workshop as well as other contributions relating to the topics of the workshop. Details can be obtained from the local organizers and the webpage www.zpr.uni-koeln.de/AFS/conferences/CTW2001/CTW2001.html http://www.zpr.uni-koeln.de/AFS/conferences/CTW2001/CTW2001.html Cologne, May 2001
