Final report CO2 emissions study for Dutch public transport delivered

bis-co2-1The final report of the CO2 emissions study for the Dutch public transport (PT) bus concessions has been completed and delivered to CROW KpVV (the Dutch Transport Knowledge Research Centre). Together with Balancia, Fimotions has successfully estimated the CO2emissions per passenger-kilometre in 2013 emitted by PT busses in the 18 PT authorities in the Netherlands.

CO2 emissions per passenger-kilometre are calculated by dividing the total CO2 emissions with the total passenger-kilometres for each PT authority. The calculation of the total CO2 emissions is broken down into Tank-to-Wheel (emissions produced by the operation of the bus itself) and Well-to-Tank (emissions produced by fuel production/processing and fuel delivery). The challenge came when we needed to calculate the average Tank-to-Wheel emissions as there are several standards for exhaust emission measurement (Braunschweig cycleESC/ETC cycle, etc) for different bus technologies (such as diesel, biofuels, natural gas, hybrid and electric).

Another challenge was the forecast of the passenger-kilometres (i.e. the kilometres travelled by passengers on busses) because the latest data was from 2009 which showed the situation before the introduction of the OV-chipkaart(a contactless smart card system for all public transport in the Netherlands).  Based on this data, a forecast of the passenger-kilometres in 2013 was made for each PT authority by making use of several assumptions.

Besides the figures of CO2 emissions per passenger-kilometre for each PT authority, some other interesting findings also emerged from this study. Which PT authority has the lowest and which one has the highest CO2emissions? We will let you know once CROW KpVV has officially published the results of this study. We’ll be back soon!
