The transport sector includes emissions from fuel combustion in road transportation, civil aviation, railways and navigation. The emission from transport sector in 2016 amounted to 6,137 kt CO-eq, which makes about 24.9% of total Croatia's greenhouse gases emission. In the 'with existing measures' scenario in the period from 2020 to 2035, projections indicate a slight increase in emissions by 2030 and a slight decrease in emissions in 2035. Factors that encourage the growth of emissions are expected increase in economic activities and living standards, while the emission reductions are primarily affected by the measures to increase energy efficiency and use of electric energy and renewable sources in transport. Most of the existing measures have defined duration by 2020 so in this scenario not many measures are simulated after 2020. In scenario 'with additional measures', in the period from 2020 to 2035, projections show a slight increase in emissions in 2020 and a stagnation and a slight decrease in emissions in 2035, primarily due to planned measures to increase the share of rail transport and development of electric vehicles, which will be the key condition for the strong reduction of emissions in transport sector in long term.
