Revision of Zinc emissions over time

The significant changes in the National Total reported for 1990 (-1,212 t | -72 %) result almost entirely from recalculations in NFR 1.A.3.b vi (-1,212 t | -93 %) where the EF for zinc emissions from tyre and brake wear have been aligned with the EMEP Guidebook 2019.

The fundamental changes in the National Total reported for 2017 (-1,782 t | -85.67 %) result almost entirely from recalculations in NFR 1.A.3.b vi (-1,808 t | -93 %).
However, the most significant relative change occurs in NFR 1.A.4.a i with + 215,610 % compared to last year's submission.
