Emission trends of nitrogen oxides (EEA member countries, EU-27 Member States)
The 'with measures' (WM) projections reported by Member States take into account currently implemented and adopted policies and measures. Where countries have instead reported 'business as usual' or 'current legislation' projections, it is assumed for comparison purposes that these are equivalent to a WM projection. The 'with additional measures' projections reported by Member States take into account additional future planned policies and measures but which are not yet implemented.
- In 1990, the total emissions of nitrogen oxides to the air in the EU were around 17 000 kt.
- Between 1990 and 2006, the total emissions of nitrogen oxides have steadily declined.
