Background:Rising greenhouse gas levels through the use of traditional ICE technology in the transport industry have created a worldwide environmental crisis. Battery Electric Bus adoption is a prominent alternative currently being discussed in the public transport industry and represents an inevitable change towards a sustainable future.

Purpose:The establishment of a theoretical framework that analyzes primary and secondary data todefine the factors promoting BEB implementation.

Method:The study follows a qualitative research approach gathering data in the form of semi-structured interviews which are analyzed to develop an objective theory.

Conclusion:The results show that the primary factors influencing diffusion of BEBs are technology factors, macro-economic factors, and socio-political factors. The research defines the relationships between them to further understand their effects on BEB diffusion. The findings develop a theoretical framework around these factors and their effects on one another and the diffusion of BEBs in the industry.
