Among the Nordic countries, Iceland's cap is zero and other countries' are above zero. For the second commitment period (2013-2020) the issuing of RMUs is based on a country-specific forest management reference level (FMRL) and a cap of 3.5% of emissions in 1990. The RMUs can be used by the party to meet its GHG emissions reduction targets or sold to other parties to meet their targets set under the Kyoto Protocol.
