Revision of SO2 emissions over time

The small changes in the National Total reported for 1990 (-12.92 kt | -0.24 %) result mainly from revised emission estimates in NFRs 1.A.3.b iii and 1.B.2.a iv together with less significant changes throughout NFRs 1 and 2.
However, the strongest relative change occurs for NFR 1.B.2.a iv (+2,797,210 %).
