Bio-Ethanol in Public Transport: An Integrated Approach to Evaluate the Impact of Climate Change Policies in Urban Areas, 2014

The implementation of climate change policies as mitigation measures against greenhouse gas (GHG) emissions may create complex changes in the atmosphere. Particular sectors such as transport have been affected by abatement actions, and the measures have included moving from fossil based energy to increased use of bio-fuels. This, however, may create new environmental challenges. While the GHG emissions will be reduced, emissions of other compounds may increase. An example is the use of bio-ethanol for transportation which is increasing worldwide. The project "Bio-Ethanol in Public Transport: An Integrated Approach to Evaluate the Impact of Climate Change Policies in Urban Areas, 2014" is funded by the Norwegian Research Council, and aims to investigate the impact of bioethanol fuelled vehicles. In order to add light and contribute to the understanding of emissions from bio-ethanol, an innovative measurement campaign was carried out in Oslo as case-study and specific organic and inorganic compounds were measured. The BieBus project evaluates the implementation of an integrated assessment tool for the evaluation of alternative fuels in transport via air pollution measurements, dispersion modelling and cost analysis.
