This document discusses green buses in Scotland, noting that the country's bus fleet would need to be replaced at a rate of 276 buses per year to be fully renewed by 2030 or 118 per year by 2050. It provides data on the costs of Euro VI diesel, hybrid, and electric buses, finding that hybrids have lower fuel and operating costs than diesels. The document outlines challenges for transitioning to more environmentally friendly buses at scale, changing perceptions to speed adoption, and balancing reducing emissions with increasing ridership.
