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, each offset project must submit to annual, independent verification by an ARB-accredited verification body.  Regulatory requirements for verification of Offset Project Data Reports are provided in the Cap-and-Trade 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 composed of both quantification methodologies and regulatory program requirements to develop an ODS project for generating ARB offset credits.

ARB Compliance Offset Protocol

Ozone Depleting Substances offset projects listed on or after January 1, 2015 must use the November 14, 2014 Compliance Offset Protocol and all associated documents.  A project listed under the 2011 protocol may continue to report under that protocol or may transition to the 2014 protocol.  A Project may transition only at the time of submitting the initial Offset Project Data Report to the Offset Project Registry (see section 95973(a)(2)(D)).
