As I promised you in my last post, here is another poster that was presented at the TRA conference during the previous week, which deals with non-exhaust road transport emissions. The particular poster is quite related to the previous poster. More precisely, the research work – both calculations and literature review – was carried out simultaneously and, in the end, it was divided into two separate papers/posters. In any case, if you are interested in any of these posters send me an email and I will send you back the corresponding paper (around 10 pages). I hope that you will find this poster interesting.
- Non-exhaust emissions are not regulated. Today emissions of PM10 from wear processes are about equal to exhaust emissions and will dominate traffic-related PM emissions in the near future.
- Improvement, determination, and harmonization of road transport non-exhaust PM emission factors (EFs) – 40 compounds in total.
- EFnon-exhaust = tyre wear + brake wear + road wear and resuspension
- COPERT 4 and a combined methodology (literature review plus COPERT 4).
- EFs correspond to urban, rural, and highway conditions.
- Only one EF for each pollutant for all EU-27 countries.
- For technologies up to Euro 6, Euro VI, and Euro 4, EFs are taken equal to those of Euro 4, Euro IV, and Euro 2 (no improvement).
- For future technologies, Euro 7, Euro VII, and Euro 5, EFs are taken to be 30% lower (assuming the maximum technically feasible future reductions due to):
a. better brake pads and discs
b. reformulated rubber mixtures for tires
c. appropriate adjustment of pavement properties
d. use of dust suppressants to keep road surfaces wet
Non-exhaust EF Results
- A database of road transport non-exhaust EFs was developed based on COPERT 4 and a detailed survey of the available literature.
- Resuspension, road surface wear, and studded tire effects were included.
