Montreal Protocol on Substances that Deplete the Ozone Layer United Nations Environment Programme (UNEP) Report of the Technology and Economic Assessment Panel, Vol. 3, Decision XXXIII/5

Executive Summary:

Under Decision XXXIII/5 on “Continued provision of information on energy efficient and low-global-warming-potential technologies”, parties requested the Technology and Economic Assessment Panel to prepare a report on energy efficient and lower- global- warming- potential technologies and on measures to enhance and maintain energy efficiency during hydrofluorocarbon transition in equipment for consideration by the Open-ended- Working Group at its forty-fourth meeting. Parties requested TEAP in the report to:

(a) Update information in the decision XXXI/7 report where relevant, and address additional subsectors not previously covered such as the heat-pump, large commercial refrigeration and larger air-conditioning system sub-sectors;

(b) Assess potential cost savings associated with adoption of lower global warming potential energy efficient technologies in each sector, including for manufacturers and consumers;

(c) Identify sectors where actions could be taken in the short term to adopt energy efficient technologies while phasing down hydrofluorocarbons;

(d) Identify options to enhance and maintain energy efficiency in equipment through deploying best practices during installation, servicing, maintenance, refurbishment or repair;

(e) Provide detailed information on how the benefits of integrating energy efficiency enhancements with the hydrofluorocarbon phase-down measures can be assessed.
