Main drivers

CO total emissions show a falling trend over the whole interval, with emission reductions of 77.5 % between 1990 and 2017 and a stagnation of emission reductions in the last years. The Main Driver for CO emissions is Fuel Combustion (NFR 1.A) with 90% of total 1990 emissions and an 83% reduction between 1990 and 2017. 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 nearly all of it. Reductions close to 90% in those categories between 1990 and 2017 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 81% reduction between 1990 and 2017.
