Main drivers

CO total emissions show a falling trend over the whole interval, with emission reductions of over 73% between 1990 and 2011 and a slight decrease of emissions in 2011 compared to the very strong year 2010. The Main Driver for CO emissions is Fuel Combustion (NFR 1.A) with 89.5% of total 1990 emissions and a 77% reduction between 1990 and 2011. 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 2011 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 30% of 1990 Fuel Combustion emissions with close to a 70% reduction between 1990 and 2011.
