This guide, published by the Stockholm Environment Institute in collaboration with the Comisión de Regulación de Agua Potable y Saneamiento Básico (CRA), provides a methodological framework for water utility companies to evaluate investments aimed at ensuring the continuity and coverage of aqueduct services. It emphasizes a comparative analysis between 'grey' infrastructure, demand management, and 'green' environmental investments (restoration and conservation) to manage the gap between water supply and demand, particularly during dry seasons.

This report by the Climate Policy Initiative analyzes the cost-effectiveness and feasibility of decarbonizing Indian Railways (IR) by 2030. It evaluates various pathways for the traction and non-traction segments, concluding that transitioning to renewable energy—specifically through captive generation at an accelerated rate—is significantly cheaper than a business-as-usual scenario. The report emphasizes the necessity of full electrification and identifies regulatory barriers regarding state-level net metering and open access policies.

The City of Boulder Climate Action Plan Analysis Report, prepared by the Rocky Mountain Institute (RMI) in May 2012, evaluates the cost-effectiveness and emissions impact of 19 demand-side management programs funded by the Climate Action Plan (CAP) tax. The analysis finds that while Boulder has achieved significant energy savings, it will not meet its 2012 Kyoto Protocol-based emissions reduction targets through current programs alone. RMI recommends transitioning toward more comprehensive, integrated, and long-term energy efficiency strategies and suggests that municipalization of the energy supply could significantly enhance the city's ability to reach its goals.

This 1995 report by the Stockholm Environment Institute, conducted as a UNEP project with the National Environmental Protection Agency of China, analyzes the environmental impacts of energy planning in the People's Republic of China. Using the LEAP/EDB model, the study compares a Business-As-Usual (BAU) scenario against two enhanced environmental scenarios to forecast pollutant emissions (SO2, CO2, NOx, PM, and CO) through 2020. The report identifies coal as the primary driver of pollution and recommends a shift toward a cleaner energy mix, improved energy efficiency, and the implementation of integrated energy-environment planning and economic instruments to achieve sustainable development.

The Help My House (HMH) Loan Pilot Program tested the use of on-bill financing (OBF) to implement energy efficiency measures in 125 homes served by South Carolina's electric cooperatives. The program demonstrated that OBF can significantly reduce residential electricity use and costs while maintaining high member satisfaction, serving as a cost-effective alternative to new power generation investment.
