According to Head of Department of Environmental Research dr. Steigvilė Byčenkienė the largest source of main GHG - CO2 emission is the energy sector (including transport) that accounted 79.7% of the total national CO2 emission (excl. LULUCF) in 2017. The energy industries contribute 23.5% and the transport sector accounts for 53.2% of the CO2 emission in energy section. During the period 1990-2017 the share of transport sector significantly increased. In 1990 transport sector accounted for 17.6% of total GHG emission in energy sector whereas in Lithuania’s – 50.7%.This growth is influenced by the rapid increase of the density of transport routes and the number of road vehicles.
The estimated total GHG emissions in CO2eq. from 1990 to 2017 and sectoral share of emissions in 2017.
Upon its independence from the Soviet Union in 1990, Lithuania inherited an economy with high energy intensity. A blockade of resources, imposed by USSR during 1991-1993 led to a sharp fall in economic activity, as reflected by the decrease of the Gross Domestic Product (GDP) in the beginning of nineties. The economic situation improved in the middle of the last decade and GDP has been increasing until 1999 (during 1999-2000, GDP decreased due to the economic crisis in Russia) and GDP continued increasing from 2001 to 2008. In 2009 GDP decreased due to the world economic crisis and the slight growth of GDP in 2011 was observed. These fluctuations were reflected in the country’s emissions of greenhouse gases.
