European Union flag

The figure shows the base AEI as the complete bar (consisting of the blue and the orange parts) and the 2023 AEI as the blue part of the bar. Furthermore, it indicates the concentration corresponding to the required percentage reduction (NERT), dependent of the base AEI, as dark blue triangles.

Total stacked bars indicate the initial baseline AEI for 2010 or 2011 (AEI 2015 in the case of Croatia, see the main text).

Triangles indicate the NERT to be met in 2023, applying the percentage reduction to the AEI baseline.

Blue bars indicate the reported AEI2023. If the triangle is to the right of the blue bar, the NERT was achieved in 2023.
