Hur påverkas ännu icke-reglerade luftföroreningar från trafik av åtgärder för att minska CO2 emissionerna?

Reference number
Funding from Vinnova SEK 4 883 488
Project duration November 2013 - July 2018
Status Completed

Purpose and goal

The main aim of this project has been achieved by developing new knowledge, using a unique method, concerning emissions from transport that can be used to develop new sustainable transport solutions. The goal was to gain a comprehensive view of particles and co-emitted gases originating from traffic, which also includes the potential contribution of secondary particle formation through the development of a method that allows chemical and physical characterisation of the primary emission and the secondary formation from individual emission plumes.

Expected effects and result

The use of biofuels (RME, HVO, gas) generally gives lower emissions of primary particles regarding mass compared to conventional diesel. However, the number of particles may increase. The potential secondary particle formation was significant for all the fuels tested. Until one has appropriately addressed and abated the issue of secondary aerosol formation there is no combustion related technology or fuel available on the market that could be considered to represent a clean transport option.

Planned approach and implementation

The aim to develop new knowledge regarding traffic emissions was achieved by carrying out extensive measurement studies using road- and sea-traffic. We combined our newly developed method for characterising individual vehicles/ships with advanced state-of-the-art high resolution mass spectrometry as well as an oxidation flow reactor (Go:PAM) to enable detailed understanding of the emissions and its properties.
