- 
-=== Emission factors === 
- 
-The majority of emission factors for exhaust emissions from road transport are taken from the 'Handbook Emission Factors for Road Transport' (HBEFA, version 4.1) [((bibcite 2))] where they are provided on a tier3 level mostly and processed within the TREMOD software used by the party [((bibcite 1))].  
- 
-However, it is not possible to present these highly specific tier3 values in a comprehendible way here.

-> **NOTE:** With respect to the country-specific emission factors applied for particulate matter, given the circumstances during test-bench measurements, condensables are most likely included at least partly.[[footnote]] During test-bench measurements, temperatures are likely to be significantly higher than under real-world conditions, thus reducing condensation. On the contrary, smaller dillution (higher number of primary particles acting as condensation germs) together with higher pressures increase the likeliness of condensation. So over-all condensables are very likely to occur but different to real-world conditions. [[/footnote]]

-For heavy-metal (other then lead from leaded gasoline) and PAH exhaust-emissions, default emission factors from (EMEP/EEA, 2019) [((bibcite 3))] have been applied. 
-Regarding PCDD/F, a tier1 EF from (Rentz et al., 2008) [((bibcite 4))] is used.

-===== Discussion of emission trends ===== 
- 
-> **NFR 1.A.3.b i** is key category for **NH,,3,,**, **NO,,x,,**, **NMVOC**, **CO**, **PM,,2.5,,** and **PM,,10,,**. 
- 
-== Non-methane volatile organic compounds (NMVOC), nitrogen oxides (NO,,x,,), and carbon monoxide (CO) == 
- 
-Since 1990, exhaust emissions of **nitrogen oxides**, **NMVOC**,  and **carbon monoxide** have decreased sharply due to catalytic-converter use and engine improvements resulting from ongoing tightening of emissions laws and improved fuel quality.

-[[/gallery]] 
- 
-== Ammonia and sulphur dioxide == 
- 
-As for the entire road transport sector, the trends for **sulphur dioxide** (SO,,2,,) and **ammonia** (NH,,3,,) exhaust emissions from passenger cars show charcteristics very different from those shown above: Here, the strong dependence on increasing fuel qualities (sulphur content) leads to an cascaded downward trend of SO,,2,, 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 == 
-//(from fuel combustion only; no wear/abrasion included)//  
- 
-Starting in the middle of the 1990s, a so-called "diesel boom" began, leading to a switch from gasoline to diesel powered passenger cars. As the newly registered diesel cars had to meet the EURO2 standard (in force since 1996/'97) with a PM limit value less than half the EURO1 value, the growing diesel consumption was overcompensated qickly by the mitigation technologies implemented due to the new EURO norm. During the following years, new EURO norms came into force. With the still ongoing "diesel boom" those norms led to a stabilisation (EURO3, 2000/'01) of emissions and to another strong decrease of PM emissions (EURO4, 2005/'06), respectively. Over-all, the increased consumption of diesel in passenger cars was overastimated by the implemented mitigation technologies. The table below shows the evolution of the limit value for particle emissions from passenger cars with diesel engines. 
- 
-With this submission, Black Carbon (BC) emissions are reported for the first time. Here, EF are estimated based on as fractions of PM as provided in [((bibcite 3))]. 
-Due to this fuel-specific fractions, the trend of BC emissions reflects the ongoing shift from gasoline to diesel ("dieselisation").

-===== Recalculations===== 
- 
-Compared to submission 2020, specific **activity data** for passenger cars were revised within TREMOD for all years due to re-allocations of consumption shares between the different vehicle types and classes. 
-In contrast, the **over-all fuel consumption** in road transport remains **unaltered**, with the only changes occuring for 2017 due to the implementation of the now finalised NEB 2017 (see [[[1-a-3-b-road-transport | superordinate chapter]]]).
