  1. NUTS level: hierarchical system to divide the territory from national level (NUTS 0) to small regions (NUTS 3). SoEF: Data derived from SoEF 2020 database, available only at national level. The SoEF data have been modified with gap-filling procedures compared to the original values only where indicated. NFI: Data derived from the harmonised NFI data, available at sub-national level, updated using SoEF data but not matching the SoEF values. The NFI data used in this study have been always processed, updated and harmonised, and thus differ from the NFI data provided by the original data source. CBM: Data derived from the Carbon Budget Model (CBM). SoEF & NFI: Data derived from the harmonised NFI data at sub-national level, updated to match the SoEF values at national level. When the data source did not provide all variables, the missing values were estimated using gap-filling procedures. GF: Data completely derived using gap-filling procedures, using data from other countries. gf1: Data partly derived from gap-filling procedures, using data from the same country. gf2: Data partly derived from gap-filling procedures, using data from other countries.
