Division B National exposure reduction target
United Kingdom
| Exposure reduction target relative to the AEI in 2010 | Year by which the exposure reduction target should be met | |
|---|---|---|
| Initial concentration in μg/m3 | Reduction target in percent | 2020 |
| < 8,5 = 8,5 | 0 % | |
| > 8,5 — < 13 | 10 % | |
| = 13 — < 18 | 15 % | |
| = 18 — < 22 | 20 % | |
| ≥ 22 | All appropriate measures to achieve 18 μg/m3 | |
Where the AEI in the reference year is 8,5 μg/m3 or less the exposure reduction target shall be zero. The reduction target shall be zero also in cases where the AEI reaches the level of 8,5 μg/m3 at any point of time during the period from 2010 to 2020 and is maintained at or below that level.
