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. In 2021 the consumption of lubricants slightly rebound. | 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< | 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.
