The report applies the SAVi simulation service to the Saloum Delta in Senegal, quantifying the monetary value of its wetlands and mangroves. It assesses the economic trade-offs between business-as-usual trends, infrastructure development (roads and oil extraction), and conservation efforts (organic agriculture, mangrove reforestation, and solar cookstoves). The analysis provides a baseline for policy-makers and investors to design conservation finance solutions and sustainable development strategies.

The document applies the SAVi methodology to the Dakar BRT project, demonstrating that while conventional financial analysis suggests the project is not viable, the integration of external effects—such as time saved and avoided pollution—reveals substantial net benefits for Senegalese society. The analysis covers four scenarios, including variations in passenger demand, and predicts a net job loss of 14% in the transport sector, offset by a 15.6% increase in discretionary spending across the wider economy.

The SAVi assessment of the N’Diaye wind farm in Senegal demonstrates that while coal-fired power may appear more financially attractive under traditional business-as-usual scenarios, the wind farm provides superior societal value and lower costs when climate risks and externalities are integrated. The wind project is estimated to generate 158.7 MW of electricity and create significantly more employment (66 FTE/year) with substantially lower life cycle emissions (0.1 million tonnes of CO2) compared to coal (6.1 million tonnes) and HFO (2.2 million tonnes). When accounting for climate risks and externalities, the levelized cost of electricity (LCOE) for the wind farm is CFA 43,266 per MWh, making it more affordable than coal (CFA 52,998 per MWh) and HFO (CFA 155,728 per MWh).

The SAVi assessment of the Taïba N’Diaye wind farm demonstrates that while traditional financial metrics may favor fossil fuels due to lower initial capital costs, the wind project provides superior societal value and lower long-term costs when climate risks and externalities are integrated. The wind farm is projected to generate 158.7 MW of electricity and create significantly more jobs with far lower lifecycle emissions than coal or HFO alternatives.

The SAVi assessment concludes that a sustainable infrastructure scenario—combining railway expansion and sustainable buildings—would generate a cumulative discounted net benefit of KZT 2,424 billion (USD 5,259 million) between 2022 and 2050. While a traditional benefit-cost ratio (BCR) of 0.82 would suggest the project is not investment-worthy, the sustainable benefit-cost ratio (S-BCR) is 8.53 when accounting for societal and environmental externalities. The most significant economic driver is the value added from freight trade, totaling KZT 2,452 billion (USD 5,319 million), assuming a 60% shift from road to rail transport. The report recommends prioritizing electrified rail and energy-efficient buildings to reduce CO2 emissions and operational costs, noting that solar power is cheaper than fossil fuel generation for the project's energy needs.

The document evaluates four scenarios for restoring Beira Lake: business-as-usual, wastewater treatment upgrades, dredging, and a combined approach. Using the SAVi tool, it analyzes the impact of these interventions on water clarity, property values, and recreational spending between 2020 and 2025. While the combined approach (Scenario 4) generates the highest total benefits, wastewater treatment upgrades (Scenario 2) offer the highest benefit-to-cost ratio.

The SAVi assessment of the Tirana-Durres railway project in Albania demonstrates that while the project is not economically viable based on traditional financial metrics, it provides substantial societal benefits. The project, estimated to cost EUR 58.78 million, is projected to generate cumulative discounted net benefits of EUR 270.34 million between 2023 and 2053. The most significant gains come from avoided vehicle operating costs (EUR 96.78 million) and health benefits from reduced air pollution and increased physical activity (EUR 44.93 million). The sustainable benefit-cost ratio (S-BCR) is 4.25 (or 4.79 in Table 1), compared to a conventional BCR of 0.12.

The SAVi assessment of the Uchkuduk-Kazakhstan Border Highway in Uzbekistan indicates that while the project has a low traditional benefit-cost ratio of 0.18, its sustainable benefit-cost ratio (S-BCR) is significantly higher at 1.38 to 1.95. The project is expected to generate cumulative discounted net benefits between USD 230 million and USD 567 million over a 30-year period (2022-2052), driven primarily by public revenues from raw materials trade and avoided traffic accident costs.

The assessment concludes that the onshore wind portfolio is a more resilient and profitable investment than a comparable gas-fired power plant when climate risks and externalities are internalized. While the wind portfolio's performance slightly diminishes when externalities are monetized, the gas-fired plant becomes financially unattractive, with its internal rate of return (IRR) turning negative under a carbon tax scenario.

The document details the analytical approach used to estimate up to $91 billion in savings for Minnesota by comparing 'business-as-usual' transportation scenarios against targets for VMT reduction and net-zero emissions. It describes the monetization of avoided crash fatalities, air quality improvements, fuel and operating costs, and the social cost of carbon.

The report investigates the captive predator breeding industry in South Africa, specifically focusing on lions. It challenges industry claims of economic significance and conservation value, arguing that the industry relies on deceptive marketing to attract volunteer tourists and supplies the 'canned hunting' and lion bone trades. The author contends that the industry lacks scientific grounding, suffers from genetic inbreeding, and may facilitate organised crime through the legal export of lion skeletons to Asia. The paper suggests that the opportunity costs—including damage to South Africa's tourism brand and the loss of potential jobs from ethical ecotourism—outweigh the industry's private returns, recommending a move toward a zero export quota for lion derivatives.

The report assesses the current state of cooking energy in Madagascar, where over 80% of rural households rely on wood and over 60% of urban households use charcoal. It models a 'Base Scenario' aligned with national policy and a 'Universal Access Scenario' aligned with SDG7, estimating the fuel production potential for bioethanol, biogas, and pellets. The analysis highlights that while bio-fuels have significant potential without impacting food security, the primary barrier to adoption is the cost of fuel, which represents 97.1% of transition costs. Transitioning to clean cooking could reduce residential energy consumption by up to 65% and prevent thousands of deaths from indoor air pollution by 2030.

The document describes an Excel-based economic model designed to assess the Nigerian solar value chain, specifically focusing on Solar Home Systems (SHS) and mini-grids. It outlines how users can simulate different scenarios—importation, local assembly, and local manufacturing—to determine their effects on product pricing, job creation, government revenue, and greenhouse gas emissions. The manual details the model's dashboards, input sheets, and the underlying cost-per-watt and bottom-up methodologies used to derive costs and tariffs.

The report evaluates Malawi's progress toward clean cooking goals, highlighting a significant gap between current ownership and 2030 targets. It identifies affordability and low stove durability as primary barriers, estimating a $108.8M investment needed for the Compact scenario and $246.0M for the more ambitious IEP scenario. The IEP scenario envisions a total phase-out of fuelwood and charcoal by leveraging universal electrification for e-cooking and expanding biofuels. The report emphasizes the need for durable stoves, innovative financing, and regional strategies, particularly in the Northern region, to reduce health risks and gender-based time burdens associated with fuel collection.

The W-Fuel project investigated the feasibility of producing biomethane from locally sourced biodegradable waste, sludge, manure, and energy crops in northern Estonia. The study focused on two pilot sites: the Hinnu pig farm in Harju County and a proposed plant in Rakvere, Lääne-Viru County. Findings indicate that while CHP production may be more commercially profitable due to existing feed-in tariffs, upgrading biogas to biomethane for transport fuel is more socially and environmentally beneficial, particularly when accounting for the EU Emissions Trading Scheme (EU-ETS). The report also provides detailed biomass availability forecasts for 2020 and recommends specific waste prevention measures and governmental support schemes to facilitate the transition to gaseous renewable fuels.

This report, published by the Stockholm Environment Institute in November 2009, presents a calculation and simulation model for the social costs of land transport in Estonia. It estimates the total external costs for 2007, breaks them down by cost type and vehicle category, and analyzes the extent to which these costs are internalized through existing taxes and fees.

The report analyzes the energy transition of the Galápagos Islands, focusing on the total elimination of fossil fuels by 2040. It evaluates four demand sectors—residential, commercial/public, land transport, and maritime transport—and proposes three levels of policy ambition (Low, Medium, and High). Key strategies include replacing LPG with induction stoves and solar water heaters, electrifying land transport, and implementing a mix of slow steaming, wind-assisted propulsion, and biofuels for the maritime fleet. On the supply side, the report models the transition to 100% renewable electricity using solar PV, wind, Concentrated Solar Power (CSP), and geothermal energy. It concludes that while technological substitutions are generally cost-effective, structural infrastructure changes in buildings are not. The report also highlights the role of national subsidies and proposes an 'Eco Tax' for tourists to fund the transition.

The report analyzes 40 low-carbon interventions in Mexico's electric power, oil and gas, energy end-use, transport, and agriculture and forestry sectors. It finds that implementing these measures could stabilize emissions at 2008 levels by 2030, avoiding approximately 477 Mt CO2e relative to a baseline scenario. Many of these interventions are 'no-regrets' options with positive economic returns, though their scale-up is hindered by institutional, regulatory, and financial barriers.

The report finds that Rwanda faces significant economic costs from existing climate variability and future climate change, particularly in health, agriculture, and water sectors. It estimates that future climate change could cost Rwanda nearly 1% of its GDP annually by 2030, excluding extreme events. Adaptation costs are projected to range from $50 million to $600 million per year by 2030, depending on whether development-related needs are included. The study also identifies a low-carbon growth pathway as being in Rwanda's self-interest to avoid 'lock-in' to high-emission infrastructure and to access carbon financing.

Ethiopia's Long-Term Low Emission and Climate Resilient Development Strategy (2020-2050) establishes a pathway to net-zero emissions by 2050. The strategy analyzes four scenarios: Business-as-Usual (BAU), NDC-aligned, Maximum Ambition, and Late Action. It prioritizes decarbonization in energy, transport, agriculture, forestry, waste, and industrial processes (IPPU). Key pillars include expanding renewable energy, electrifying transport, enhancing carbon sinks through reforestation, and modernizing agriculture. The document emphasizes a 'just transition' through a Women and Youth in Green Jobs Program and identifies a significant financing gap, estimating a total investment requirement of USD 154 billion for the NDC-aligned scenario.
