The Danish Minister of Finance, Nikolaj Wammen, has set out that the green transition should become a  central part of the Finance Ministry’s core business. As part of this, Denmark is developing a new macro economic model, GreenREFORM, designed to assess the economic and fiscal impact of climate and  environmental policies, as well as the climate and environmental impact of economic policies.  The GreenREFORM model consists of a main dynamic computable general equilibrium model (CGE model) and several sub-models that describe sectors in the economy that are particularly important in terms of climate and environmental impact (for instance, transport and agriculture). The model  describes the total economic activity in Denmark and combines the results of the sub-models. Green REFORM is designed as a fully integrated model system where all sub-models and the main model are  linked and solved simultaneously.
