Destruction of Ozone Depleting Substances (ODS) and High-Global Warming Potential (GWP) Foam from International Sources

1.0

The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, has open for public comment a Methodology for the Quantification, Monitoring, Reporting and Verification of Greenhouse Gas (GHG) Emissions Reductions from the Destruction of Ozone Depleting Substances (ODS) and High-Global Warming Potential (GWP) Foam from International Sources. The Methodology builds on ACR’s existing ODS and High GWP Foam destruction methodology - applicable only for U.S. domestically sourced ODS and foam - adding applicability, eligibility, and monitoring provisions for ODS and foam sourced from locations outside of the U.S. and its territories. The methodology was developed by Tradewater and ACR. 

Chloroflourocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are, amongst other uses, coolants used in refrigeration and air conditioning systems, aerosol sprays, fire suppression systems and medical devices as well as in foam blowing agents for the manufacture of insulation and noise reduction in buildings, appliances, coolers, marine applications and industrial pipe insulation. CFCs and HCFCs are classified as Ozone Depleting Substances (ODS) because they deplete the stratospheric ozone layer. Additionally, they have extremely high GWPs in most cases.

Under the Montreal Protocol, the production of CFC refrigerants is phased out and the production of certain HCFCs is currently being phased out. However, the use of these ODS is not prohibited. In certain situations, the ODS may be recycled but this practice leads to ODS refrigerants leaking into the atmosphere at very high rates. Worse still, ODS are sometimes vented during servicing or disposal of equipment though certain countries ban this practice.  

The ACR Methodology provides a framework for the quantification, monitoring, reporting and verification of GHG gas emission reductions associated with the sourcing and destruction of: 1) High global warming potential (GWP) ODS sourced from air conditioning and refrigeration equipment; 2) High-GWP foam blowing agents that are extracted from insulation foam; and 3) Insulation foam that contains blowing agent(s) with high GWP. All eligible ODS must be sourced from locations outside of the U.S. and its territories.
