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 {it Joint-Implementation}. It is an international program which intends to strengthen international cooperations between enterprises in order to reduce CO₂-reductions. For that reason the nonlinear time-discrete TEM model (Technology-Emissions-Means model) was developed, giving the possibility to simulate such an extraordinary market situation. Within the TEM-model we are able to introduce control parameters.
In this paper we consider the problem of local controllability of such a nonlinear time-discrete dynamical system by norm bounded controls. This problem is solved with the aid of minimum norm control problems. At the end numerical examples of the implemented algorithm are presented.
