Why do we estimate?

National Emissions Ceilings Directive (NECD)

Air pollution travels over long distances, affects human health, degrades buildings and other man-made structures and adversely affects the natural environment through acidification, eutrophication and ground-level ozone.  The European Community agreed to set emission ceilings through the National Emission Ceilings Directive (NECD) to protect its citizens, its man-made structures and its diverse environments.  The revised NECD (2016/2284/EU), which entered into force on 31 December 2016, sets new emission reduction commitments for each Member State for the total emissions of NOx, SOx, NMVOC, NH3 and PM2.5 in 2020 and 2030. The new Directive repeals and replaces Directive 2001/81/EC to ensure that the emission ceilings for 2010 set in that Directive shall continue to apply until 2020.  Member States have to report their emission inventories annually to the European Environment Agency (EEA) and the European Commission in order to monitor progress and verify compliance.  The reporting requirement is closely aligned with those for the Convention on Long-range Transboundary Air Pollution (CLRTAP), which include a common scope of reporting of pollutant inventories and similar reporting timeframe.  Under the revised NECD, each Member State is required to publish by April 2019 a National Air Pollution Control Programme, setting out the measures it will put in place to reduce emissions to meet the 2020 and 2030 emission reduction commitments. 

The UK is meeting its targets:  Analysis of compliance is undertaken every year and presented in the EEA’s NECD status reports (latest version 2015).  The UK has met its targets for all four pollutants for all years since 2010 inclusive.
