Ozone 2010 - Target value for the protection of vegetation: In the air quality directive (2008/EC/50), the EU has set a target value and a long term objective value for ozone (O3) for the protection of vegetation. Target value: the AOT40 may not exceed 18000 (µg/m3) per hour in the period from 1 May to 31 July averaged over five years. Long term objective value: the AOT40 may not exceed 6000 (µg/m3) per hour in the period from 1 May to 31 July within a calendar year. AOT40 (expressed in (μg/m3) ∙ hours) means the sum of the difference between hourly concentrations greater than 80 μg/m3 (= 40 parts per billion) and 80 μg/m3 over a given period using only the one-hour values measured between 8.00 and 20.00 Central European Time (CET) each day. More information is provided in Annex VII of directive (2008/EC/50).

Ozone 2010 - 8 hour mean target value for the protection of human health: In the air quality directive (2008/EC/50), the EU has set a target value and a long term objective value for ozone (O3) for the protection of human health. Target value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) on more than 25 days per calendar year averaged over three years. Long term objective value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) within a calendar year.

Emission trends of tropospheric (ground-level) ozone precursors (EEA member countries, EU-27): This chart shows past emission trends of nitrogen oxides (NOx), non-methane volatile organic compunds (NMVOC), carbon monoxide (CO) and methane (CH4) in the EEA-32 and EU-27 group of countries. In addition - for the EU-27 - the aggregated Member State 2010 emission ceilings for NOx and NMVOC are shown.

Production of ozone depleting substances (EEA-32), 1986-2011: Production is defined under Article 1(5) of the Montreal Protocol as production minus the amount destroyed minus the amount entirely used as feedstock in the manufacture of other chemicals.
