Recalculations - Sulphur Oxides

The negligibly small changes in the National Total reported for 1990 (-4.15 kt or -0.08 %) result almost entirely from revised emission estimates in the sub-categories of NFR 1.A.3.b together with less significant changes throughout NFR 1 with the strongest change occuring for 2.C.1 with minus 25 kt but resulting from a re-allocation of emissions to NFR 2.C.7.c.

The strongest percental change, however, occurs for 2.C.1 with minus 85 %.
