Main drivers

CO total emissions show a falling trend over the whole interval, with emission reductions of 78.6 % between 1990 and 2015 and a continuing decrease of emissions starting in 2011 and continuing to 2015. The Main Driver for CO emissions is Fuel Combustion (NFR 1.A) with 90% of total 1990 emissions and an 84% reduction between 1990 and 2015. In the Fuel Combustion category, Road Transport (NFR 1.A.3.b) is responsible for more than half of the 1990 emissions, with Passenger Cars (NFR 1.A.3.b.i) emitting over 90% thereof. Reductions over 88% in those categories between 1990 and 2015 are mainly due to constantly improving fuels and increasingly stricter regulations resulting in technical improvements. Other Sectors (1.A.4, including commercial/institutional and residential sources) are responsible for nearly a third of 1990 Fuel Combustion emissions with a 82% reduction between 1990 and 2015.
