Revisions in these statistics

The emission and removal figures for the greenhouse gas inventory become revised every year in the entire time series, because constant improvements are made to the inventory, taking into account the international review recommendations of inventories and the development of the scientific basis for emission calculation methods. In addition, the preliminary data are based on more detailed activity data than the instant preliminary data, which is compiled when not all the necessary data are yet available. The changes in calculations are described in the annual National Inventory Report submitted to the UN and the EU.

The now released preliminary total emissions without the LULUCF sector for 2020 are 0.2 million tonnes of CO2 equivalent (0.4%) lower than in the instant preliminary data released in May. Emissions from both the energy sector and industrial processes and product use are 0.08 million tonnes of CO2 equivalent lower than in the instant preliminary data, which is mainly due to the revisions in the emission coefficients for the recovery of F-gases and in the allocation of emissions from energy and process-based steel production. Emissions from agriculture are 0.06 million tonnes of CO2 equivalent lower than in the instant preliminary data. The emission data of the waste sector are on level with those given in the instant preliminary data.

For the LULUCF sector, calculation of the net sink becomes revised yearly for the penultimate years. This is due to utilisation of updated data, e.g. national forest inventory data, in the calculation. These data affect, e.g. the areas and growing stock which, in turn, affect the litter input to the soil and thus the soil carbon stock. According to the preliminary data of the latest release, the net sink of the LULUCF sector for 2020 is 5.7 million tonnes of CO2 equivalent lower than in the instant preliminary data based on more incomplete data published in May (see review of this release).
