Emission factors

Emissions factors for exhaust emissions from road transport are taken from the 'Handbook Emission Factors for Road Transport' (HBEFA, version 3.1) where they are provided on a tier3 level mostly and processed within the TREMOD software used by the party. Therefore, it is not possible to display them in a clear and comprehendible table. - For further information, please see the Handbook Emission Factors for Road Transport and the TREMOD software.

Trend discussion for Key Categories

NFR 1.A.3.b iii - Exhaust emissions from heavy duty vehicles is key source for emissions of

  • NOx regarding level and trend,
  • PM2.5 regarding level and PM10 regarding level and trend.

Nitrogen oxides (NOx)

Until 2005, NOx emissions followed mileage and fuel consumption. Since 2006, in contrast to nearly unchanged fuel consumption, emissions have decreased due to controlled catalytic-converter use and engine improvements resulting from continual tightening of emissions laws.

Non-methane volatile organic compounds (NMVOC) and carbon monoxide (CO)

Since the early 1990s, exhaust emissions of NMVOC and carbon monoxide have decreased due to catalytic-converter use and engine improvements resulting from ongoing tightening of emissions laws and improved fuel quality.

Ammonia (NH3) and sulphur dioxide (SO2)

As for the entire road transport sector, the trends for sulphur dioxide (SO2) and ammonia (NH3) exhaust emissions from heavy duty vehicles show charcteristics different from those shown above: Here, the strong dependence on increasing fuel qualities (sulphur content) leads to an cascaded downward trend of SO2 emissions , influenced only slightly by increases in fuel consumption and mileage. For ammonia emissions the increasing use of catalytic converters in gasoline driven cars in the 1990s lead to a steep increase whereas both the technical development of the converters and the ongoing shift from gasoline to diesel cars resulted in decreasing emissions in the following years.

Particulate matter (PM2.5, PM10, and TSP)

As for all reported exhaust PM emissions from mobile diesel vehicles the party assumes that nearly all particles emitted are within the PM2.5 range, resulting in similar emission values for PM2.5, PM10 , and TSP.

Recalculations

Recalculations were carried out impacting all pollutants due to a regular revision of the HBEFA (Handbook Emission Factors for Road Transport 3.1) and the TREMOD software.

AD: Activity data were revised within the TREMOD model used by the inventory compiler as well as in the CSE data warehouse. Here, changes in data for all years result mostly from reallocations of consumption shares between the different vehicle types and classes with over-all sums remaining nearly unchanged whereas changes in 2009 data also result from a slightly revised Energy Balance.

EF: Emission factors were revised broadly within the 'Handbook Emission Factors for Road Transport' (HBEFA, version 3.1) and, hence, within TREMOD. Due to the number of EFs effected, it is not possible to present old and revised values in a proper way. For further information please refer to HBEFA 3.1 here.

For pollutant specific information on qualitative and quantitative impacts on 1990 and 2008 emission estimates see chapter 11. Recalculations and the following chapters.

Uncertainties

Uncertainty estimates for activity data of mobile sources derive from research project FKZ 360 16 023: "Ermittlung der Unsicherheiten der mit den Modellen TREMOD und TREMOD-MM berechneten Luftschadstoffemissionen des landgebundenen Verkehrs in Deutschland". For detailled information, please refer to the project's final report here (German version only!)

Uncertainty estimates for emission factors for all 1.A.3.b sub-categories were compiled during the PAREST research project. Here, the final report has not yet been published.

Planned improvements

At the moment, no category specific improvements are planned.
