4 and 4(a). The latter shall be filled with "NA" for not applicable, with the explanation "Numbers for LULUCF are not reported because this sector is not included under the Convention target". The use of flexible mechanisms takes place on the one hand by operators in the EU ETS, on the other hand by governments for the achievement of ESD targets. For information on the use in the ETS please see the Third Biennial Report of the European Union (section 3.2.2.1). The use of flexible mechanisms in Slovakia currently takes place only by operators in the EU ETS. Slovakia is not planning to use international credits in the ESD scheme for meeting the annual trajectory target. Slovakia is well on track for meeting its emission reduction targets resulting from international and EU commitments. In 2015 anthropogenic GHG emissions decreased by 44.6% compared to 1990. Considering EU commitment for sectors covered by the EU ETS and sectors not covered by the EU ETS and covered by the ESD to decrease its emissions by 20% compared to 1990 Slovakia is also on the track to meet its commitments. GHG emissions in the ETS decreased in 2015 by 16.05% compared to 2005 and ESD emissions, even Slovakia has positive target of 13% up to 2020, decreased in 2015 by 23.24% compared to 2005.
