Quantification Of Non-Exhaust Road Transport PM Emissions

About

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.

Introduction

• 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.

Method

• 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

Conclusions

• 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.
