Are energy-related emissions of ozone precursors decreasing?

Energy-related emissions accounted for 87% of all Carbon Monoxide (CO) emissions, 44% of all Non-Methane Volatile Organic Compounds (NMVOC) emissions, 95% of all Nitrogen Oxide (NOx) emissions and 48% of all Methane (CH4) emissions from the EEA-32 in 2008. Energy related emissions of these pollutants in the EEA-32 fell by 4%, 3%, 5% and 1% respectively between 2007 and 2008, and since 1990, these emissions have declined by 53%, 59%, 30% and 44% in EEA member countries. The largest reductions in emissions occurred in the road transport sector, largely as a result of the continued introduction of catalytic converters in new vehicles during this period. Energy production and use still remains a significant source of emissions for these precursor pollutants. Reducing energy-related emissions of ozone precursors therefore is a key priority for reducing local and transboundary air pollution and in ensuring that the EU and individual countries meet emission ceiling targets under the National Emissions Ceilings Directive (NECD) and the UNECE Gothenburg Protocol, meet their limit values under Directive 2008/50/EC on ambient air quality and cleaner air for Europe and the Air Quality Framework Directive and its daughter directives.
