Trend discussion for Key Categories

NFR 1.A.3.b v - Gasoline evaporation is key source for emissions of

  • NMVOC regarding the emissions' declining trend.

Non-Methane Volatile Organic Compounds - NMVOC

(fugitive emissions only; no NMVOC emissions from fuel combustion included)

Since its maximum level of over 11 kilotonnes in 1990, the amount of evaporated gasoline is decreasing - and so are the related NMVOC emissions. The amounts of evaporated gasoline are connected directly with those of gasoline consumed. Here, the decrease becomes sharper from 2000 onwards following a growing switch from gasoline to diesel oil especially in passenger cars. Here, the annual amounts of NMVOC emissions from evaporation not only depend directly on the amount of evaporated gasoline but also on the number of vehicles equipped with mitigation technologies. Thus, the decrease is sharpest straight after 1990 and since then slowing down.

Recalculations

Recalculations were carried out due to a regular revision of the HBEFA (Handbook Emission Factors for Road Transport 3.1) and the TREMOD software.
Here, the by far biggest impact results from significantly changed emission factors and much smaller changes within the annual amounts of evaporated gasoline

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 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.
