Destruction of Ozone Depleting Substances and High-GWP Foam

1.0

The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, has in the approval process a new Methodology entitled: Emission Reduction Measurement and Monitoring Methodology for Destruction of Ozone Depleting Substances and High-GWP Foam. The Methodology was co-developed by ACR and EOS Climate.

This Methodology is an update to the California Air Resources Board’s (CARB) Compliance Offset Protocol for Ozone Depleting Substances (ODS) Projects, dated November 14, 2014 (“CARB ODS Protocol”), authored by EOS Climate. The purpose of the Methodology is to quantify greenhouse gas emission reductions associated with the destruction of: 1) High global warming potential (GWP) ODS sourced from and destroyed within the U.S. that would have otherwise been released to the atmosphere; 2) High-GWP foam blowing agents that are extracted from insulation foam; and 3) Insulation foam that contains blowing agent(s) with high GWP.

The CARB ODS Protocol was first adopted in 2011 and subsequently revised in 2014. However, all of the underlying information relevant to additionality, quantification, and monitoring in the CARB ODS Protocol can be traced back to data and other information from 2008-2009 or earlier. In the years since, there have been a number of significant changes in underlying regulatory conditions, market dynamics, baseline scenarios, and new technical data. These changes are incorporated into the updates in this Methodology.

The Methodology updates the CARB ODS Protocol to include additional sources of ODS used as refrigerant in air conditioning and refrigeration equipment, ODS in medical aerosol applications and fire suppression, and ODS and other high-GWP blowing agents in foam. Additionally, modifications have been made to emission factors and methods used to generate emission reductions for foam projects and to methods used for monitoring destruction events conducted at destruction facilities that are a part of an enclosed equipment de-manufacturing system.
