About two months ago, Balancia in association with Fimotions, has completed a study for CROW KpVV to estimate the CO2 emissions per passenger-kilometre in 2013 emitted by public transport buses in the 18 Public Transport Authorities (PTA) in the Netherlands (see this link). Last week, CROW KpVV has officially published the report on her website (in Dutch). Would you like to have a summary of the study result in English? Please contact us here. We would also love to hear from you should you want to discuss it.

Based on this research, Arnhem Nijmegen City Region came up as the greenest PTA in the Netherlands thanks to the deployment of electric (trolley) and green gas buses. In 2013, the public transport buses in this region produced 17 gram CO2 per passenger-km. This number is much lower than the second greenest PTA (Province of Flevoland) that produced 87 gram CO2 per passenger-km. The other PTAs produced between 110 and 130 gram CO2per passenger-km, while the highest amount is 177 gram.

What is interesting from this study is that the PTAs of the four big cities (Amsterdam, The Hague, Rotterdam and Utrecht) produced relatively high CO2 emissions. The explanation is actually quite simple. This study only investigated the CO2 emissions of public transport buses. Those cities are the only cities in the Netherlands that have other urban public transport modes than bus, i.e. tram and/or metro. In this situation, the modal share of the bus is the lowest one in comparison with the modal share of tram and metro. This means lower passenger kilometres which result in higher CO2 emissions.

This research also proved that electric mobility will significantly reduce the CO2 emissions emitted by public transport. Electrification of urban busses promises many benefits as they cover a shorter distance than regional busses do, due to the current limitation of battery capacity.

Currently, the number of electric buses counts only 1% of the entire public transport bus fleet in the Netherlands and this percentage has not grown since 2010. As we wrote in this blog, most public transport authorities and operators would not come up with electric buses in the first place. A perception that “operating electric buses is always more expensive than diesel buses” is still very strong. We do believe that the total cost of ownership of electric buses is not higher than that of diesel buses. Do you agree with us? Let us know your opinion by filling in the form here below.
