Recalculations - Nitrogen Oxides

Revision of NO_x emissions over time

The small changes within the National Total reported for 1990 (-4.38 kt | -0.15 %) are dominated by changes in NFRs 1.A.3.b i, 1.A.3.b ii and 1.A.3.b iii together with less significant revisions throughout NFRs 1, 2 and 3.
Here, the strongest relative change occurs for NFR 1.B.2.a iv (+222,250 %).
