===== Recalculations ===== | ===== Recalculations ===== | ||
- | With emission factors revised for each plant, recalculations of NOx have been carried out compared to last year's submission. So far a T1 method with a T1 Default EF was used. With the sabmissionsubmission 2022 a T2 method is applied with T2 EFs. The total emissions from 1990 to 2019 for the latest two submissions and their difference are listed in **Table 2**. | ||
