Climate change is a subject that has been largely addressed from both macroeconomic and energetic standpoints. Integration of climate variables and natural capital into the traditional economic framework can appear conflicting with the notion of infinitely growing economies exploiting finite resources, which questions the sustainability of neoclassic economic growth models. Moreover, the temporal dimension is of paramount importance and the integration of inter-temporal utility is not a trivial issue. The construction of complex general equilibrium models is a way to model the response of economic systems to shocks.
