for PM2,5:
|
(a)
|
when 10 years before the AEI was < 10,0 μg/m3: 10 % lower than the AEI was 10 years before or 8,5 μg/m3, whichever is the lower, unless the AEI is already no higher than the average exposure concentration objective for PM2,5 set out in Point C;
|
|
(b)
|
when 10 years before the AEI was < 12,0 μg/m3 and ≥ 10,0 μg/m3: 15 % lower than the AEI was 10 years before or 9,0 μg/m3, whichever is the lower;
|
|
(c)
|
when 10 years before the AEI was ≥ 12,0 μg/m3: 25 % lower than the AEI was 10 years before;
|
|
|

for NO2:
|
(a)
|
when 10 years before the AEI was < 20,0 μg/m3: 15 % lower than the AEI was 10 years before or 15,0 μg/m3, whichever is the lower, unless the AEI is already no higher than the average exposure concentration objective for NO2 set out in Point C;
|
|
(b)
|
when 10 years before the AEI was ≥ 20,0 μg/m3: 25 % lower than the AEI was 10 years before.
|
|
When calculating the levels for the years 2030, 2031 and 2032, Member States may exclude the year 2020 from the calculation of the AEI for the base year. C. Average exposure concentration objectives The average exposure concentration objective shall be the following level of the AEI.

(1) The maximum daily 8-hour mean concentration shall be selected by examining 8-hour running averages, calculated from hourly data and updated each hour. Each 8-hour average so calculated shall be assigned to the day on which it ends, i.e. the first calculation period for any 1 day shall be the period from 17:00 on the previous day to 01:00 on that day; the last calculation period for any 1 day shall be the period from 16:00 to 24:00 on that day.
(2) The maximum daily 8-hour mean concentration shall be selected by examining 8-hour running averages, calculated from hourly data and updated each hour. Each 8-hour average so calculated shall be assigned to the day on which it ends, i.e. the first calculation period for any 1 day shall be the period from 17:00 on the previous day to 01:00 on that day; the last calculation period for any 1 day shall be the period from 16:00 to 24:00 on that day.
(3) The maximum daily 8-hour mean concentration shall be selected by examining 8-hour running averages, calculated from hourly data and updated each hour. Each 8-hour average so calculated shall be assigned to the day on which it ends, i.e. the first calculation period for any 1 day shall be the period from 17:00 on the previous day to 1:00 on that day; the last calculation period for any 1 day shall be the period from 16:00 to 24:00 on that day.
(4) If the 3- or 5-year averages cannot be determined on the basis of a full and consecutive set of annual data, the minimum annual data required for checking compliance with the ozone target values shall be as follows:
|
—
|
for the target value for the protection of human health: valid data for 1 year,
|
|
—
|
for the target value for the protection of vegetation: valid data for 3 years.
|
(5) Until 1 January 2030, 120 μg/m3 not to be exceeded on more than 25 days per calendar year averaged over 3 years.
