The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, has approved an update to its Methodology for the Quantification, Monitoring, Reporting and Verification of Greenhouse Gas Emissions Reductions and Removals from Advanced Refrigeration Systems. The Methodology update was developed by Dentons US and EOS Climate in cooperation with Susan Wood Consulting and True Manufacturing.

The intent of the Methodology is to incentivize GHG emissions reductions through the deployment and use of advanced refrigeration systems in large commercial and stand-alone commercial refrigeration.

The refrigerant industry has been moving to introduce advanced commercial refrigerant technologies for some time, yet the adoption of these technologies has been slow. Such systems may deploy refrigerants such as hydrocarbons, ammonia, carbon dioxide, and hydrofluoroolefins as alternatives to HCFC or HFC refrigerants that are commonly used. The Methodology includes a framework to incentivize the increased uptake of these available alternatives in commercial refrigeration.

The Methodology is based on a robust data set, including the United Nations Environment Programme Technical Options Committee for Refrigeration, Air Conditioning and Heat Pumps, the U.S. EPA Vintaging Model, the U.S. EPA GreenChill Partnership, and the 2006 International Panel on Climate Change Guidelines for Greenhouse Gas Inventories.
