The energy sector covers all activities that involve fuel combustion from stationary sources and fugitive emission from fuels. The emission from energy sector in 2014 amounted to 10,817 kt CO and it is the main source of anthropogenic emission of greenhouse gases, it accounts approximately 46.9% of the total greenhouse gases emission in 2014. In scenario without measures', i.e. without implementation of energy efficiency measures and renewable energy policy and with the increase in a number of fossil fuel power plants to reduce the import of electricity by 2030, projections show steady growth until 2035. In the 'with existing measures' scenario, projections show stagnation of emissions until 2020 as the growth of demand is mainly satisfied by the development of the renewable energy sources and energy efficiency. In the period from 2020 to 2035, this scenario shows a slight decrease due to expected development of the renewable energy sources even without the additional measures, only due to market competitiveness and impact of the EU ETS. Most measures to reduce emissions in the energy sector are defined by 2020, so it has not yet been determined which will be implemented after 2020. In scenario 'with additional measures', all measures planned in the energy sector were taken into account and projections show a steady trend of emission reduction.
