This technical report describes the Sustainable Asset Valuation (SAVi) methodology and its application to various infrastructure types to calculate the costs of environmental, social, governance, and climate risks, as well as externalities. It specifically explores how SAVi can be integrated into Indonesia's Vision 2045 (IV2045) system dynamics model to better inform low-carbon development and investment strategies by bridging top-down national planning with bottom-up asset-specific analysis.

This report presents a Sustainable Asset Valuation (SAVi) assessment of three stormwater infrastructure options in the Paterson Park Precinct of Johannesburg, South Africa: a grey concrete culvert, a nature-based stream renaturalization, and a hybrid solution. Using data from the Copernicus Climate Change Service (C3S), the study compares these options through an integrated cost-benefit analysis (CBA) and climate change scenario analysis over 20- and 40-year horizons. The findings demonstrate that nature-based infrastructure is the most cost-efficient and climate-resilient choice, providing significant co-benefits in flood mitigation and water supply.

This report provides a Sustainable Asset Valuation (SAVi) assessment of the Kalivaç and Poçem hydropower projects (HPPs) on the Vjosa River in Albania. It compares these projects against hypothetical solar PV and onshore wind alternatives, integrating environmental, social, and economic externalities into cost-benefit analyses (CBA), levelized cost of electricity (LCOE), and financial performance models. The assessment finds that the HPPs are uneconomic and socially costly compared to solar PV, primarily due to high dredging costs and significant losses in agriculture and tourism.

This report presents a Sustainable Asset Valuation (SAVi) assessment of the Bus Rapid Transit (BRT) project in Dakar, Senegal. The analysis compares a 'Business as Usual' scenario against three BRT implementation scenarios (baseline, low demand, and high demand) to evaluate the project's financial viability and its broader environmental, social, and economic externalities.

This report presents a Sustainable Asset Valuation (SAVi) assessment of the Contournement de Rabat (Rabat bypass) road project in Morocco. Using system dynamics and project finance modelling, the study evaluates the financial viability of the 41.1 km toll road across six risk scenarios and incorporates the valuation of four key externalities: discretionary spending from labour income, social cost of carbon, value of time saved, and the cost of accidents.

The Sustainable Asset Valuation (SAVi) tool, developed by the International Institute for Sustainable Development (IISD), is a simulation-based methodology designed to integrate environmental, social, and economic risks and externalities into the financial valuation of infrastructure assets.

This report by the International Institute for Sustainable Development (IISD) uses the Sustainable Asset Valuation (SAVi) tool to compare the financial and socioeconomic impacts of flood versus drip irrigation for the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) initiative, specifically within the Kilombero Valley. The analysis demonstrates that while drip irrigation has higher initial costs, it significantly improves water efficiency, unlocks additional productive land, and enhances long-term financial viability when environmental and social externalities are factored into the valuation.
