In Slovenia, the Decree on renewable energy sources in transport (Official Gazette of the Republic of Slovenia, No. 64/16) has been in force since 2016. The Decree defines the obligations of fuel suppliers who have to achieve an energy share of renewable energy in a calendar year - at least 6.2% in 2017, at least 7.0% in 2018, minimum 8.4% in 2019, and a minimum of 10.0% in 2020. A portion of renewable energy sources is obtained by the energy supplier through the sale of biofuels compatible with criteria of sustainability, electricity from renewable energy sources, hydrogen from renewable energy sources and a combination of these fuels. The Decree, in accordance with the EU Directive 2015/1513, limits the maximum contribution of biofuels, which are produced from cereals and other field crops with a high content of starch, plants for the production of sugar, oilseeds and crops, which are grown on agricultural land as main crops specifically for energy purposes, in 2020 to 7% of final transport energy consumption in the country. The NECP sets an objective for biofuels in transport for 2030 at 11%, whereby the share of advanced biofuels must be increased in accordance with the EU Directive 2018/2001. The target share of RES in transport equals 21% according to the NECP. In 2018, the share of RES in transport was 5.5% in Slovenia.
