 The emissions calculation method follows a Tier-2 approach. It uses national statistical data <sup>**[[#Bibliography| [Lit. 1]]]**</sup> for the quantities placed on the market specific per lubricant types as activity rate and specific emission factors for each lubricant type. It is assumed that the amount of lubricants placed on the market per year equals the lubricant use (consumption) in the same year. The emissions calculation method follows a Tier-2 approach.

 The consumption of lubricants in Germany has remained at a relatively constant level since 1990, apart from a sharp decrease in 2009 and in 2020.

 Along the life cycle of the different lubricant types, different kinds of losses occur. Only some types of losses are of relevance with regard to air emissions and the different lubricants types differ significantly from each other. Relevant emitted pollutants identified for lubricants are NMVOC and CO<sub>2</sub>. But only for engine oils used in machinery and in vehicles emission of both could be accounted for due to combustion of a small fraction of lubricating oils directly resulting in CO<sub>2</sub> emissions. Along the life cycle of the different lubricant types, different kinds of losses occur.

 The modifications of the Mineral Oil Statistics in 1995 show no impact of overall amount of lubricants. Only a reclassification of lubricants from unspecified application categories to specified application categories was made. The emissions for the years 1990-1994 could therefore be just up to 25% to high. The modifications of the Mineral Oil Statistics in 1995 show no impact of overall amount of lubricants.
