Emission forecast for air pollutants

Plant planners and manufacturers

Plant operators require an emission forecast for air pollutants for air pollutants emitted by the existing or planned plant. The new planning or modification of industrial and commercial plants frequently requires approval subject to emission control law. If relevant levels of air pollution are to be expected from the new or planned plant, the Technical Instructions on Air Quality Control (TA Luft) require an emission forecast for the air pollutants. A dispersion calculation is used to forecast the expected situation with air pollutants. The effects of air pollutants as humans, animals and plants as protected goods objects along with ecosystems can be assessed with the help of such a forecast.

We will be more than happy to assist you with the entire approval process here. The emission forecast is submitted to the competent authority as one of the central reports in the approval application documents. The air pollutants that the plants emit are considered part of the emission forecast, so that a legally certain statement can be made about the approvability of the plant. Our team of experts calculates the expected emissions for air pollutants using the TA Luft-compliant reference model AUSTAL2000. These are then verified using the TA Luft emission values or other recognised assessment values if necessary. In addition, we use the AUSTAL2000N model to calculate the expected deposition of nitrogen and acid as the basis for the assessment as a part of the FFH compatibility test (flora, fauna, habitat).


  • Verification of for the need to determine parameters according to TA Luft
  • Emission forecast for air pollutants according to TA Luft including assessment of measured and diffuse emission sources
  • Chimney height calculation according to TA Luft and other relevant regulation
  • Special case check according to TA Luft
  • Calculation of nitrogen and acid deposition (FFH compatibility)

The advantages for you

  • Our 30 years of expert experience minimises the planning risks for you during approval and planning approval procedures
  • Creation and coordination of the investigation framework for the emission forecast with a proportion relative to the specific project
  • Basis for the detailed assessment of plant-related nitrogen and acid depositions
  • Skilled project-specific advice leads to time and cost savings

When planning new industrial and commercial facilities from which air pollution may emanate, in many cases an immission forecast for air pollutants must be prepared as part of the immission control approval procedure. The aim is to assess the effects of air pollutants on the protected goods humans, animals, plants and ecosystems…
