Main drivers

CO total emissions show a falling trend over the whole interval, with emission reductions of 78.6 % between 1990 and 2018 and a stagnation of emission reductions in the last years. The Main Driver for CO emissions is Fuel Combustion (NFR 1.A) with 91% of total 1990 emissions and an 83% reduction between 1990 and 2018. In the Fuel Combustion category, Road Transport (NFR 1.A.3.b) is responsible for 63% of the 1990 emissions, with Passenger Cars (NFR 1.A.3.b.i) emitting nearly all of it. Reductions close to 88% in those categories between 1990 and 2018 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 over a quarter of 1990 Fuel Combustion emissions with a 82% reduction between 1990 and 2018.
