This report details the 'From Waste to Traffic Fuel' (W-Fuel) project, which investigated the sustainable production of biogas and its upgrading to biomethane for use as transport fuel in two Estonian counties: Harju and Lääne-Viru. The study compared the environmental and economic impacts of using biogas for combined heat and power (CHP) versus upgrading it to vehicle fuel, while also proposing waste prevention strategies for biowaste and sludge.

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.

This report analyzes three transport and mobility energy consumption scenarios for Estonia up to 2050, with a detailed cost-benefit analysis through 2030. It compares a 'Business-as-Usual' (BAU) approach, a 'Low-Intervention' (VS) scenario, and a 'Knowledge-Based' (EE) energy-efficient scenario, evaluating their impacts on energy use, greenhouse gas emissions, and public finances.

The revised Nationally Determined Contribution (NDC) of Mali outlines the country's updated commitments to the Paris Agreement for the 2020-2030 period. Mali aims to maintain its status as a carbon sink while increasing its mitigation ambitions across four sectors: energy, agriculture, forestry and land-use change, and waste. The document details specific emission reduction targets, adaptation strategies to combat desertification and food insecurity, and a comprehensive financing and monitoring framework, with a strong emphasis on gender integration and the involvement of non-state actors.

This report outlines a strategic plan for the sustainable energy transition of the Galápagos Islands from 2020 to 2040, aiming for 'Zero Fossil Fuels'. It analyzes demand and supply scenarios across four sectors: residential, commercial/public, land transport, and maritime transport. The study proposes various technological substitutions—such as induction stoves, solar water heaters, electric vehicles, and renewable energy generation (solar, wind, geothermal, and CSP)—to reduce greenhouse gas emissions and dependence on imported fuels. It evaluates the cost-benefit of these measures and the impact of existing energy subsidies on the transition's viability.

This report, titled "Low-Carbon Development for Mexico" (MEDEC), provides a comprehensive economic and technical analysis of options to reduce greenhouse gas emissions in Mexico through 2030. It evaluates 40 specific interventions across five sectors—electric power, oil and gas, energy end-use, transport, and agriculture and forestry—comparing a baseline scenario with a low-carbon alternative. The study finds that Mexico can stabilize its emissions at roughly 2008 levels while maintaining economic growth by implementing cost-effective, often "no-regrets" measures, many of which provide significant co-benefits in public health and energy security.

This working paper evaluates the costs and benefits of implementing financial incentives, such as purchase subsidies and registration rebates, to increase electric vehicle (EV) adoption in Ho Chi Minh City.

The Aqueduct Floods Cost-Benefit Analyzer is a tool developed by the World Resources Institute to assess the economic feasibility of investing in flood protection infrastructure, specifically dikes and levees, to protect urban areas from riverine floods.

This technical note describes the development of a Microsoft Excel-based cost-benefit analysis (CBA) tool designed to evaluate the economic viability of deploying solar irrigation pumps (SIPs) in Rajasthan, India, specifically under component C of the PM KUSUM scheme.
