The Baltic Biogas project commenced in 2009 and ended 2012. The outcomes and recommendations of the project about how to start using biogas as transport fuel are recorded on the project website at balticbiogasbus.eu/web/. Lennart Hallgren, Project Manager, concludes that biogas buses are the best choice for urban public transport to lower emissions of green house gases and improve inner city air quality while creating energy autonomy and more sustainable jobs. Biogas will also significantly contribute to reaching the EU 2020 targets.
The website has links to several successful biogas projects in Europe, including an updated feasibility study on the introduction and use of biogas buses in the Tartu City, presented at a regional seminar held in Tartu, Estonia in August 2012.
Tartu implemented biogas-fuelled public transportation in 2011.
