Compliance Offset Protocol Ozone Depleting Substances (ODS) Projects

Introduction

The Compliance Offset Protocol Ozone Depleting Substances (ODS) Projects provides methods to quantify and report greenhouse gas (GHG) emission reductions associated with the destruction of high global warming potential ozone depleting substances sourced from and destroyed within the U.S. that would have otherwise been released to the atmosphere.  This project category includes ODS used in foam blowing agent and refrigerant applications.  All destroyed ODS must be fully documented, chemically analyzed, quantified and destroyed at a qualifying facility to be eligible for crediting under this protocol.  All ODS must originate in the United States.

ODS Offset Project Operators or Authorized Project Designees must use this protocol to quantify and report GHG reductions.  The protocol provides eligibility rules, methods to quantify GHG reductions, offset project-monitoring instructions, and procedures for preparing Offset Project Data Reports.  Additionally, all offset projects must submit to annual, independent verification by ARB-accredited verification bodies.  Regulatory requirements for verification of Offset Project Data Reports are provided in the Cap-and-Trade Regulation (Regulation).

This protocol is designed to ensure the complete, consistent, transparent, accurate, and conservative quantification of GHG emission reductions associated with an ODS destruction project.  The protocol is comprised of both quantification methodologies and regulatory program requirements to develop an ODS project for generating ARB offset credits.
