Introduction

The Ontario Offset Credits regulation (the Regulation) and incorporated protocols have been designed to be consistent with the Western Climate Initiative’s (WCI) Offset System Essential Elements Final Recommendations Paper, July 2010 in order to supply high quality, compliance-grade offset credits for use in Ontario’s cap and trade program.

Protocols are a central component of Ontario’s offset program and are incorporated by reference in the Regulation. These two components work together to set out the requirements that must be met in order to be eligible for the creation and issuance of Ontario offset credits. The Regulation defines the overall process, criteria and administrative requirements involved in the creation and issuance of an offset credit, while the incorporated protocols set out the eligibility criteria and requirements specific to each initiative type or class.

The Regulation requires the use of an approved protocol to quantify greenhouse gas reductions, avoidances or removals. Each protocol establishes specific eligibility criteria, baseline scenario and initiative calculation methods, monitoring, data management and reporting requirements specific to the class of offset initiatives. This document contains the protocols that have been approved for use with respect to specific classes of offset initiatives for achieving greenhouse gas reductions, avoidances or removals that are real, quantifiable, verifiable and additional.

2. When a single flow meter is used for multiple, identical eligible destruction devices per Subsection 7.2.2(a)1, the operational status of each destruction device shall be monitored separately unless the design of the eligible destruction device is such that LFG is not released when it is not operating and there is documented evidence to support this.

   2. CH₄ destruction shall be monitored at a frequency of at least weekly during the baseline scenario monitoring period, and extrapolated to one year based on the 90% upper confidence limit of the CH₄ destruction values recorded during this period. (Note: Monitoring for a period longer than three months, or at a frequency greater than weekly, may lessen statistical uncertainty and reduce the required BD_discount.)

   3. LFG flow shall be monitored at a frequency of at least weekly during the baseline scenario monitoring period, and shall be normalized to maximum flow capacity (m³/min).
