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.
