Although it remains clear that low carbon public transport will produce less emissions than conventionally fuelled alternatives, and much less when compared to personal vehicles per person per kilometre travelled, encouraging the use of public transport has multiple barriers that need to be overcome to increase widespread use. This includes a shift in travel behaviour for consumers in terms of public acceptance of new low carbon public transport, including encouraging public transport use at younger age so that individuals continue to use public transport as they get older. The main barrier remains the cost of the technology itself as well as the additional infrastructure when integrating low emission public transport. As technology advances it is expected that electric and hydrogen public transport costs will decrease, however hydrogen technology is still relatively new making this more challenging. Since travellers are cost-sensitive fares it is important that public transport remains competitive with personal vehicles. Furthermore, the practicalities of integrating new technologies need to be considered. For example, the introduction of electric and hydrogen in public transport will require additional infrastructure for charging which will have a geospatial impact on natural capital and ecosystem services. This is because electric transport will need to be charged more frequently than hydrogen transport due to the range of the vehicles. Furthermore, electrification of public transport will result in additional challenges for power generation and infrastructure development which will need to be addressed for widescale uptake. Therefore, electric charging infrastructure is more likely to be situated within city centres compared to hydrogen transport which can be situated in rural areas.
