Recalculations - Zinc (Zn)
With negligibly small changes within NFRs 1 and 2 and re-allocations in sub-categories of 1.A.3.b, the 1990 National Total remains unaltered compared to last year's submission.
However, the strongest percental change occurs in NFR 1.A.3.b ii with plus 25 %.

The changes in the National Total reported for 2020 (+5.13 t and +1 %) are dominated by opposing revisions in NFRs 1.A.3.b vi (-1.52 t) and 1.A.3.c (+6.77 t) where annual mileage and, hence, abrasive emissions were revised for 2020.
The significant percental change occuring in NFR 1.A.3.b iii results from a data error that will be corrected with the next annual submission.
