The rather remarkable changes within the National Total reported for 1990 (+1.94 t or +1.68 %) are dominated by newly implemented emission estimates for B[b]F, B[k]F and I[x]P from NFR sub-category 2.C.3, increasing the PAH emissions from this specific source by more than 200 %. Furthermore, a variety of often opposing revisions occurs for sub-categories throughout NFR 1.

The significant changes within the National Total reported for 2022 (+1.28 t or +4.92 %) are dominated by revisions in NFR sub-categories 1.A.4.b i with +1.39 t and 1.A.4.a i with -0.11 t togehter with a variety of small revisions throughout NFR 1.
However, the most significant percental change occurs in NFR 1.A.4.a ii with minus 16 %.
