GHG emissions from energy sector in comparison to other sectors most dramatically decreased during the 1990 - 1995 followed by a slight increase, because this sector is a major consumer of fossil fuels, which is characterized by a sharp decrease in consumption (see Fig. 2.22). The total GHG emissions of the sector in 2010 amounted to 33.1% of 1990 emissions. Simultaneously, with emissions cuts, its distribution to individual source categories has significantly changed. The share of GHG emissions in the energy production category was 39% in 1990, then by 1997 had risen to 51%, finally decreasing consistently and reaching 21% by 2010. The share of emissions in the industry and construction category was 8% in 1990 and by 2000 had increased to 9%, decreasing to 6% by 2010. The share of emissions in the transport category steadily grew over the entire period under review, from 15% in 1990 to 38% in 2010. The share of emissions in the other sectors category in 1990 was 33.5%, and decreased to 16% in 1997, with a consequent increase in 2010 to 23%. Emissions by the fugitive emissions from fuels category in 1990 amounted to 4.5% of the total emissions and for a long time did not significantly change, but after 2000, there was a sharp increase and by 2005 emissions peaked at 24.5% before decreasing to 11% in 2010. As a result, in 2010 the transport category became the category with the highest emissions, whereas in 1990 the highest emissions were observed in the energy category.
