The document outlines the SAVi methodology applied to Ulaanbaatar's bus fleet, utilizing causal loop diagrams and integrated cost-benefit analysis to evaluate the transition from internal combustion engine (ICE) buses to electric vehicles (EVs). It details the indicators used—ranging from GHG emissions and air pollution to retail revenues and employment—and provides the specific data assumptions, such as a 10-year implementation period and a 40% reduction in maintenance costs for electric buses compared to ICE buses.

The assessment finds that nature-based infrastructure (stream renaturalization) is the most cost-efficient and climate-resilient option, providing the highest net benefits primarily through avoided flood damages and additional water supply. While grey infrastructure (concrete culverts) has the highest upfront costs and provides no environmental co-benefits, nature-based solutions maintain superior performance across various climate scenarios, although they are more labour-intensive to maintain.

The SAVi assessment finds that the Kalivaç and Poçem hydropower projects (HPPs) are uneconomic, producing higher costs and societal burdens than benefits. When integrating externalities, the HPPs' levelized cost of electricity (LCOE) is more than 2.5 times higher than that of solar PV. The report highlights significant negative externalities, particularly the loss of agricultural land and tourism potential along the Vjosa River, and notes that the projects are not financially attractive at domestic electricity prices of EUR 55/MWh.

The report evaluates the 41.1 km Rabat bypass road project using the SAVi tool, simulating six risk scenarios and four externalities. It finds that the project is not financially viable based on its own revenues across all scenarios, with negative net present value and insufficient internal rate of return. However, the inclusion of externalities—specifically the value of time saved and the cost of accidents—significantly improves key financial indicators, demonstrating that traditional financial analyses underestimate the project's broader socio-economic value and the risks associated with reduced maintenance or climate change.
