In October 2024, the PAREMPI project successfully conducted two extensive measurement campaigns to analyze emissions from the aviation and marine sectors. Both campaigns took place at VTT’s facilities in Otaniemi, Espoo, Finland, and involved a dedicated team of 35 experts from multiple partners across Europe. The campaigns were led by VTT in collaboration with Tampere University and the Finnish Meteorological Institute from Finland, with key contributions from ONERA (France) and IEM (Czech Republic). BOSMAL, as the Work Package leader from Poland, closely followed both measurement processes to ensure alignment with project objectives.
Aviation Campaign
From 30 September – 14 October 2024 at VTT in Otaniemi, Espoo, Finland
The aviation-focused campaign centered on assessing emissions from simulated aircraft exhaust, covering gases, semivolatiles, particles, secondary aerosols, and biological effects. ONERA’s expertise in creating representative aircraft exhaust simulations enabled the team to collect robust data across various emission types. An extensive set of Sustainable Aviation Fuels (SAFs) included in total of eight types of aviation fuels and lubricating oils.
The campaign employed advanced instrumentation to analyze secondary particle formation from precursor emissions, aiming to gain a deeper understanding of how aviation emissions contribute to secondary aerosols under different environmental conditions. These findings will help advance research in reducing aviation’s environmental impact.
Marine Campaign
From 15 – 25 October 2024 at VTT in Otaniemi, Espoo, Finland
The marine campaign simulated ship emissions using a diesel generator, replicating exhaust emissions with a variety of marine fuels. The campaign included tests on commercial DMB-grade marine fuel, as well as fuels with varying sulfur, aromatic, and ash contents. Ammonia-containing exhaust was also studied to understand its emissions profile when used with selective catalytic reduction (SCR) systems or as a potential marine fuel. Low-sulfur diesel fuel and biodiesel were also examined.
To deepen the analysis, the team integrated a permeation oven into the exhaust line to study how individual aromatic and long-chain hydrocarbon compounds influence secondary aerosol formation. Comprehensive instrumentation was deployed to capture data on secondary particulate emissions in the marine sector, which can provide valuable insights for managing environmental impacts in maritime transport.

Both campaigns presented complex setups and required extensive preparation to ensure a smooth transition between them without compromising the specific goals of each. The findings from these campaigns mark significant progress in PAREMPI’s mission to develop effective strategies for reducing emissions in aviation and marine sectors, supporting a cleaner, more sustainable future for European transport.
