Footnotes: 

a  Note that for most UK reporting we present CRT codes without full stops between characters, however, the formal CRT includes these. For example, in most NAEI datasets, we present 2B10b, but in the formal CRT this would appear as 2.B.10.b
b  Note that or most UK reporting we present LULUCF CRT codes with a modification where the roman numerals in brackets appear in the code when it starts deviating from what the categories without roman numerals in brackets mean, wheras in the formal CRT, the roman numerals in brackets always appear immediately after the first character. For example, in most NAEI datasets, we present 4A1(IV)b, but in the formal CRT this would appear as 4(IV).A.1.b; in this example, 4A1 has the same meaning as elsewhere (i.e. Forest Land remaining Forest Land), but the b after the (IV) has a different menaing to a b after (I) (i.e. wildfires and organic N fertilisation respectively).
