1.The central administrator shall ensure that on 1 May of each year, the Union Registry indicates the compliance status figure for the preceding year for every installation and aircraft operator with an operator or aircraft operator holding account that is not in a closed status by calculating the sum of all allowances surrendered for the current period less the sum of all verified emissions in the current period up to and including the preceding year, plus a correction factor. The compliance status figure shall not be calculated for accounts that had their previous compliance status figure zero or positive and the year of last emissions was set to a year before the preceding year. The calculation shall not take into account the surrender of allowances issued for a period subsequent to the current compliance period.
The central administrator shall ensure that the Union Registry calculates the compliance status figure before the closure of the account pursuant to Articles 25 and 26.
2.For the trading periods 2008-2012 and 2013-2020, the correction factor referred to in paragraph 1 shall be zero if the compliance status figure of the last year of the previous period was greater than zero, but shall remain the same as the compliance status figure of the last year of the previous period if this figure is less than or equal to zero. For the trading periods starting on 1 January 2021, the correction factor referred to in paragraph 1 shall be the same as the compliance status figure of the last year of the previous period.
3.The central administrator shall ensure that the Union Registry records the compliance status figure for every installation and aircraft operator for each year.
