Main drivers

CO total emissions show a falling trend over the whole interval, with emission reductions of over 75% between 1990 and 2013 and stagnating emissions in 2013 compared to the previous year. The Main Driver for CO emissions is Fuel Combustion (NFR 1.A) with close to 90% of total 1990 emissions and a 73% reduction between 1990 and 2013. 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 80% in those categories between 1990 and 2013 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 70% reduction between 1990 and 2013.
