Large combustion plants are still a major source of emissions of various air pollutants. By the mid-1990s emissions of particulate matter sulphur dioxide nitrogen dioxide and carbon monoxide had declined significantly. Thereafter the specific emissions remained largely stable over many years. In the course of regulatory changes a changing composition of the plant park as well as changes in fuel usage there has been a significant reduction for sulphur dioxide (SO2) in recent years but also changes for NOX and particulate matter. It was therefore essential to update the existing factors. Due to the regulatory requirements and the associated monitoring obligations extensive data are available for these pollutants. The available emission values were evaluated for various years. As a result the specific emission factors are presented in the following document and if necessary qualitatively evaluated. |
