The Amsterdam Transport Authority (Vervoerregio Amsterdam, VRA) aims to achieve a fully CO₂‑neutral mobility system by 2030. To support this ambition, Decisio carried out a social cost benefit analysis (SCBA) of zero-emission bus transport in the region. The key question: is it socially advantageous to switch entirely to electric buses now?
The study examined both the financial and societal impacts of different technologies. Financial impacts include investment and maintenance costs for buses and charging infrastructure. Societal impacts include reduced emissions, lower noise levels and improved ride comfort, but also potential drawbacks, such as increased visual intrusion from new charging stations or power cables in the urban landscape.
Zero-emission technologies are currently more expensive than diesel, mainly due to higher upfront investment in vehicles and infrastructure. However, zero- emission buses require less maintenance. The SCBA shows that the societal benefits outweigh these higher financial costs. In other words, switching to zero-emission transport is already socially advantageous. Among the technologies assessed, ‘opportunity charging’ performs best.
For the SCBA, it was assumed that the entire VRA bus fleet would be replaced at once. In practice, the transition will take place in stages, creating opportunities for optimisation. Zero‑emission technology is developing rapidly, and costs are likely to fall in the coming years. Different technologies may also be combined in an optimal scenario. The SCBA demonstrates that the benefits of zero‑emission buses are substantial, and that switching to opportunity charging is already socially beneficial. With future technological advances and smarter phasing, the societal benefits will only increase.
Emission‑free bus transport is high on the sustainability agenda of transport authorities. A key question is whether the technology is ready for large‑scale deployment, or whether it would be better to wait before making major investments. With the Climate Act in mind, the pressure to act is increasing, and waiting may no longer be an option. An SCBA compares the financial and societal impacts of different alternatives. For the Amsterdam Transport Authority, our SCBA shows that switching now delivers higher societal benefits than societal costs. An SCBA provides clear insight into the effects of transitioning to zero‑emission transport and supports informed policy decisions.
