The objective of this plan is to promote energy efficiency and energy production from renewable sources. A specific target for renewable energies was set in 1997: to attain at least 3.2% of electricity distributed from renewable sources by the end of 2000. MAP was a voluntary agreement between the energy sector and the Ministry of Economic Affairs. A MAP levy was charged at about 1.8% on energy consumption. This levy was used to finance programmes to meet the objective and target, which were designed and implemented by utilities. In 1997, a system of green labels was introduced by the utilities to distribute the cost burden of the renewable electricity target over the utilities in a more equal manner. This is effectively a quota system with tradable certificates.
