The PAREMPI project made a significant impact at the European Geosciences Union (EGU) General Assembly 2025, held from April 27 to May 2 in Vienna, Austria. Focusing on advancing research in transport emissions and air pollution, PAREMPI’s contributions were particularly notable in the poster sessions, which garnered considerable attention and engagement.
The European Geosciences Union (EGU) General Assembly 2025 proved once again to be the world’s foremost platform for Earth, planetary, and space science research. The annual event attracted more than 18,000 on-site participants, along with a significant online audience. Hosted at the Austria Center Vienna — the venue for EGU gatherings since 2005 — the 2025 edition featured an astonishing array of over 19,000 abstracts presented across more than 1,000 sessions, reinforcing its status as a premier space for scientific exchange and debate.
Driving the Conversation on Transport and Air Quality
PAREMPI co-organised the session titled “Transport and Air Pollution: From Real-World Emissions to Their Impacts,” which attracted over 60 abstract submissions, including nine from the PAREMPI consortium. Convened by our partners Hilkka Timonen, FMI and Paivi Aakko-Saksa, VTT, this session underscored the commitment to addressing transport emissions and improving air quality through cutting-edge research by PAREMPI and similar initiatives.
Highlighting Poster Session Success
The poster sessions were a standout success of PAREMPI’s participation. Held on-site on Wednesday, April 30, from 16:15 to 18:00 in Hall X5, these sessions featured in-depth studies on topics such as the secondary aerosol formation potential of various vehicles and volatile organic compound concentrations in exhaust emissions. The interactive nature of the poster sessions facilitated meaningful discussions and knowledge exchange among researchers and attendees. Posters presented by Katariin and Hilkka Timonen, FMI received a lot of interest from the audience present during the two hour poster sessions.
Showcasing PAREMPI’s Air Quality Research
PAREMPI’s oral presentations took place on multiple days throughout the week and covered a range of innovative research areas.
On Monday, 28 April, Michal Vojtisek, IEM opened the series with his presentation on the potential of on-board FTIR as a single instrument capable of simultaneously measuring all relevant gaseous pollutants under real-driving conditions.
The next day, Tuesday, 29 April, featured two presentations. Wojciech Honkisz, BOSMAL discussed emission measurements from Plug-In Hybrid Light-Duty vehicles tested on custom RDE cycles under both road and laboratory conditions. Later that evening, Topi Rönkkö, VTT presented significant findings on the extremely low black carbon emissions observed from modern passenger cars and heavy-duty vehicles.
On Wednesday, 30 April, the program continued with multiple noteworthy contributions. The specialised session “Transport and Air Pollution: From Real-World Emissions to Their Impacts” was convened by our partners Hilkka Timonen, FMI and Päivi Aakko-Saksa, VTT.
Petteri Marjanen, Tampere University began the day with insights into fresh and secondary exhaust emissions resulting from lubricating oil blended into marine fuel. The morning session was also a great opportunity to present the PAREMPI Air Quality Anthem realised in the context of the heavy-duty vehicles measurements campaigns last year in Tampere. The anthem was written and produced by the PAREMPI researchers Petter Marjanen and Hannu Kuutti using engine sounds recorded during the campaign.
Following this, Päivi Aakko-Saksa, VTT discussed the role of polyaromatic hydrocarbons emitted from modern cars and trucks in cold ambient temperatures, emphasizing their contribution to particulate matter and semi-volatile compounds. Later in the afternoon,
Michal Vojtisek, IEM’s presentation focused on assessing exhaust gas exposure using a portable air-liquid interface chamber in real driving conditions.These studies provided valuable insights into urban air quality and emission control strategies, contributing to the broader discourse on sustainable transport solutions.
Matti Rissanen, Tampere University concluded PAREMPI’s presence in the oral sessions with a presentation exploring how aerosol grow in a real atmosphere. This study focuced on the measurement of aerosol precursor gases during a highly complex urban air simulation campaign SAPHIR-CHANEL.
PAREMPI’s active involvement in EGU 2025 highlights its role in advancing transport and air pollution research. The project’s findings are poised to inform policy recommendations and support the development of effective emission reduction strategies across Europe.

PAREMPI Project General Assembly
On the 1st of May, the PAREMPI partners met for the General Assembly to discuss the latest project developments and activities for the final year of the project. The meeting focused on the presentation of results and planning final deliverables as well as discussion on the final conference and second policy recommendations workshop planned in December 2025.
