+ | As the emission data for the 2021 reporting could not be completely revised due to staff constraints and for these reasons the emission data for 2018 had to be updated in last year's reporting, a complete recalculation of the emission data for 2019 and 2020 was carried out for this year's reporting. In doing so, it was also possible to take into account the current changes in the systematics of the national production statistics and the foreign trade statistics. | ||
