This policy paper aims to highlight the need for a "systems approach" regarding the deployment of electric buses. The objective is to support decision makers in MENA with the necessary knowledge, tools and frameworks to implement necessary policies to ensure successful electric bus deployment. In line with global climate and emission objectives, electric buses must be part of a broader low or zero emission mobility strategy with public transport at its core, also including non-motorized transport components such as walking and cycling. Authorities and operators must adopt a systems approach prior to e-bus deployment to understand the new technology and its components as well as the role of new stakeholders to ensure its success.
