Abstract

Lower life cycle costs are often seen as an indicator of sustainability but do not always align with higher eco-efficiency. This study evaluates the sustainability and eco-efficiency of 13 city bus brands, including electric, diesel, and compressed natural gas (CNG) buses, focusing on environmental, socio-economic, and life cycle cost impacts. A hybrid Life Cycle Sustainability Assessment (LCSA) model, using Principal Component Analysis (PCA) and Data Envelopment Analysis (DEA), was applied to assess 34 buses in Qatar’s transportation system. The study finds that solar-powered electric buses from Turkey and India, along with CNG buses from Germany, Spain, and Sweden, offer the most sustainable options. However, lower life cycle costs do not guarantee higher eco-efficiency. The study recommends prioritizing solar-powered electric and high-performing CNG buses for policy support in public transport.
