Main drivers

CO total emissions show a falling trend over the whole interval, with emission reductions of 73% between 1990 and 2010 and an expected recovery after the 11% reduction between 2008 and 2009 due to the global economic crisis. The Main Driver for CO emissions is Fuel Combustion (NFR 1.A) with 89.7% of total 1990 emissions and a 77% reduction between 1990 and 2010. 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 2010 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 a 68% reduction between 1990 and 2010.
