The quantity of consumed tobacco has decreased in 2022 on a historical low value of 103854 t.


===== Method =====

==== Activity data====

Statistical data from the tax registration of sold tobacco, cigarettes and cigars<sup>**[[#Bibliography| [Lit. 1]]]**</sup> are used as **activity data**.\\
For the calculation of the **overall consumption quantity of tobacco** the default quantity of tobacco for cigarettes and cigars of the emission guidebook 2023(note to table 3-15 p. 23)<sup>**[[#Bibliography| [Lit. 2]]]**</sup> is chosen: a cigarette contains 1 g of tobacco and a cigar contains 5 g of tobacco.

==== Emission factors====

Here, as study was made and published in October 2016 "Entwicklung von Methoden zur Berechnung von Emissionen von Luftschadstoffen aus der Verwendung von Holzkohle, Tabak, Feuerwerk und Kerzen sowie aus dem Entfachen von Brauchtumsfeuern" from Nicola Toenges-Schuller et al., AVISO GmbH, for the Umweltbundesamt Germany. Based on this study, most of the EFs are an average value<sup>**[[#Bibliography| [Lit. 3]]]**</sup> from different studys.

==== Uncertainties ====

The tax registration statistics has a high level of accuracy. Therfore the uncertainty is only expected to be lower than 5%. The uncertainty for the amount of tobacco in cigarettes is set to 20%. As the tobacco quantity varies for cigars much more than for cigarettes the uncertainty is set to 100%.
===== Recalculations =====
