Methodology for Energy Efficiency Improvement Projects: boiler rehabilitation or replacement in industrial and district heating sectors

The proposed methodology applies to project activities that improve existing district heating systems, including boiler rehabilitation, pipe insulation, and changing from an open to a closed district heating system. The methodology is intended to be applicable to Uzbekistan and other regions with similar district heating systems.

• On October 12, 2026, the development of this methodology was rejected per the VCS Methodology Development and Review Process (PDF). After careful review, Verra determined that the proposal’s climate impact was not as high as that of other ideas. Verra will therefore not proceed this approach to the full methodology development process at this time.
