Decisions should rely more on analysis, including the calculation of CO2 abatement costs, to identify the least costly options for mitigation and to target measures accordingly. In addition, evaluations of different programmes were initially not designed to strongly influence decisions on environmental policies as the monitoring process did not rely on interim targets and indicators w'hich w'ould facilitate continued assessment of the impact of policies. Thus, the recent decision to evaluate the implementation of the Energy Concept every year, based on selected indicators in order to make rapid adjustments to the policies possible is a step in the right direction.
