The small changes in the National Total reported for 1990 (-0.08 t | -0.23 %) result almost entirely from revisions in NFRs 1.A.3.b vi (-0.07 t) and 5.E (-0.01 t).

The significant changes in the National Total reported for 2017 (-0.81 t | -8.64 %) are by far dominated by revised estimates for NFR 1.A.1.a (-0.58 t) and 1.A.3.b vi (-0.11 t), accompanied by several less significant revisions throughout NFRs 1 and 5.
