2.G(b) - Other Product use: Tobacco

In this sub-category of 2.G(b) - Other product use: Tobacco Germany reports NOₓ, NH₃, NMVOC, TSP, PM₁₀, PM2.5, Cd, Co, Cu, Ni, Zn, Benzo(a)pyrene (B[a]P), Benzo(b)fluoranthene (B[b]F), Benzo(k)fluoranthene (B[k]F), Indeno(1,2,3-cd)pyrene (I[1,2,3-c,d]P), PAH 1-4 and PCDD/F emissions from the smoking of cigarettes and cigars.

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 ^{[Lit. 1]} 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) ^{[Lit. 2]} 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 ^{[Lit. 3]} from different studys.

In contrast, as the tobacco quantity for cigars varies much stronger, the uncertainty is set to 100% here. ===== Recalculations =====
