A Sustainable Asset Valuation (SAVi) Assessment of Bus Fleet Electrification in Ulaanbaatar, Mongolia

The SAVi assessment finds that full electrification of Ulaanbaatar's bus fleet provides USD 26.3 million in net savings and benefits over 25 years, primarily driven by avoided fuel costs and lower maintenance. These benefits increase substantially if paired with a modal shift from private cars to public transport, potentially reaching USD 774.8 million if 10% of car users switch. The transition involves expanding the current fleet of 90 electric buses to 1,303 vehicles to meet national targets of 70% electrification by 2050.

• Full electrification of the bus fleet in Ulaanbaatar is projected to generate USD 26.3 million more in savings and benefits than its costs over a 25-year period.
• The primary economic drivers for electrification are avoided fuel costs, valued at a cumulative, discounted USD 229.6 million, and reduced maintenance costs, valued at USD 45.7 million.
• Environmental benefits, including reduced air pollution, lower noise levels, and decreased carbon emissions, contribute an additional USD 38.6 million.
• A modal shift from private cars to public buses significantly amplifies benefits: a 5% switch increases benefits to USD 400.5 million, while a 10% switch increases them to USD 774.8 million, representing a return of USD 3.63 for every USD 1 invested.
• To achieve the target of 70% electrification by 2050, Ulaanbaatar would need to expand its current fleet of 90 electric buses to a total of 1,303 buses.
