The seventh issue of the Biofuel Cities quarterly newsletter has a special focus on the emissions of vehicles running on biofuels.
As more attention is given to sustainability issues, discussions are intensifying about the origin of the feedstock and the associated greenhouse gas emissions from producing biofuels. The article found that there is “quite a lot of data available for older vehicle models, but the effect on new engine systems, with high pressure direct injection in combination with various emission control systems is not always clear”. The issue is available in English and in Polish.
