-This data is made available basically via a co-operation agreement with the nitric acid producers and the IVA (Industrieverband Agrar). As the data provided by the producers has to be treated as confidential, it is anonymised by the IVA before submitting it to the UBA. However, one producer is delivering its data directly to the UBA. After checking this specific data, it is merged with that provided by the IVA.+This data is made available basically via a co-operation agreement with the nitric acid producers and the IVA (Industrieverband Agrar).

-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**.
