What You'll Learn

check_circleExplain how vent gas capture reduces methane emissions and creates offset opportunities below the OVG limit
check_circleDetermine whether a vent gas reduction project or subproject meets eligibility and exclusion criteria
check_circleApply the appropriate flexibility mechanism for DVG sites, crude bitumen fleet average sites and compressor seal projects

check_circleQuantify net emission reductions and separate offset eligible reductions from carbon priced reductions

About This Course

Vented natural gas is mostly methane, a greenhouse gas (GHG) with a global warming potential many times that of carbon dioxide. This course explains how emission offsets can be generated under the provincial offset system by capturing small volumes of vent gas at upstream oil and gas sites and either conserving it through pipeline injection, on-site fuel use or power generation, or destroying it through incineration or tie-in to an existing flare. It covers the project types that are excluded, the eligibility conditions for projects and aggregated subprojects, including site activity history and compliance with the overall vent gas (OVG) limit, the three flexibility mechanisms for newer sites subject to the defined vent gas (DVG) limit, sites in a crude bitumen fleet average and compressor seal venting, and the crediting periods that apply to conservation and destruction projects.

The course then works through the capped dynamic baseline, in which metered captured gas is compared against the OVG limit minus reported project venting, using worked monthly examples that include an equipment upset. It explains how baseline and project sources and sinks are identified as controlled, related or affected and why each is included or excluded, how net emission reductions are calculated, and how offset eligible reductions are separated from reductions already subject to a carbon price. Quantification details include monthly calculation periods, negative vented volumes, destruction efficiency, default emission factors and displaced fuel. The course closes with project documentation, metering, calibration, record retention and quality assurance and quality control (QA/QC) practices that support third party verification.

What Will Be Covered:

  • Methane venting, the OVG limit and the opportunity to earn offsets for reductions below it

  • Eligible conservation and destruction activities and project types that are excluded

  • Eligibility requirements for projects and aggregated subprojects, including site activity and compliance history

  • Flexibility mechanisms for DVG sites, crude bitumen fleet average sites and compressor seal venting

  • Offset crediting periods for conservation and destruction projects

  • The capped dynamic baseline with worked monthly examples, including an equipment upset

  • Identification of controlled, related and affected sources and sinks and justification for inclusion or exclusion

  • Net, offset eligible and carbon priced emission reduction calculations

  • Emission factors, destruction efficiency, displaced fuel and monthly calculation periods

  • Project documentation, metering and calibration, record keeping and QA/QC for verification
