Scoping MeetingGHG Accounting Issues Oil & Gas Exploration & Production Natural Gas Gathering & Processing October 25, 2007 Santa Fe, New Mexico
Agenda • Introductions • Background on GHG Protocols • Overview of Existing Protocols • Discussion: Cross-cutting issues • Break-out discussions: • Exploration & Production • Gathering & Processing • Wrap Up – report of break-out groups
Purpose of Today’s Meeting • Identify GHG accounting issues for annual entity inventory of emissions from upstream O&G activities • Not likely resolve accounting issues today • Goals: • ID issues that are relevant & answered elsewhere • ID issues not answered elsewhere • Create a parking lot of issues beyond the scope of today’s discussion • Assess -- is a protocol needed for these activities?
Protocol Elements • Framework document that informs consistent, comparable, transparent, accurate GHG inventory • Definitions • Scope & boundary requirements • Calculations (emission factors, methodologies)
Protocol Development Process • Conduct literature review • White paper • Multi-stakeholder workgroup develops draft protocol • Expert review • Public comment • Adoption/implementation
Voluntary vs. Mandatory Reporting? • Voluntary • Can allow for flexibility • Understand footprint • Often used for corporate disclosures • 3rd-party verification required? • Mandatory • Typically facility- or unit-based • Consistent approach across all sources • May support regulatory goals • Agency oversight?
Ongoing GHG Protocol Efforts for O&G Sector • WRI/CA Registry protocol for NG T&D • CARB mandatory reporting from petroleum refineries (draft regulation) • NMED mandatory reporting from petroleum refineries (draft regulation)
In Development: Natural Gas T&D • Scope: • Combustion, process vents, non-routine activities, LAUG, equipment leaks, indirect emissions • Discussion Paper • www.climateregistry.org • Workgroup formed by CA Registry/WRI • Expert review period • Public Comment period • Expected adoption (early 2008)
In Development: Oil Refineries • Literature review: • API Compendium • IPIECA Guidelines • State of CA technical review of API Compendium • White paper draft commissioned from CA Registry for use by ARB • www.climateregistry.org • Public workshops & public comment • Draft regulations for mandatory reporting • Regulations adopted by CARB (expected December 2007) • Protocol developed by CA Registry • Workgroup to meet December-January • Public comment February 2008 • Protocol adopted by The Climate Registry?

Guidance from Current Resources (1) • GHG Protocol • Framework: • Direct emissions (Scope 1) • Indirect emissions (Scope 2,3) • Organizational boundaries • Operational boundaries
Guidance from Current Resources (2) • CA Registry GRP • TCR GRP • Geographic boundaries • Materiality threshold • Calculations/emission factors: • Stationary combustion • Mobile combustion • Indirect emissions
Guidance from Current Resources (3) • API Compendium • Identify sources • Identify emission factors • Sample calculation methodologies
Guidance from Current Resources (4) • IPIECA Guidelines • Builds on GHG Protocol • guidance specific to petroleum industry • Inform boundaries • Examples of equity share/operational control • Identify & classify sources • Table 6.1 – Upstream Petroleum Operations • Emissions Calcs • Outlines tiered approach
Guidance from Current Resources (5) • CEC Evaluation • Gap analysis of API Compendium & IPIECA • Compares w/CCAR GRP • IDs potential users • Some outdated emission factors • IPIECA provides framework, but not program-specific applicability • Conclusion: most work needed for CH4 emissions
What are sources? Indirects Mobile Stationary Process Fugitive What terms should be defined? Geographic boundaries? Organizational boundaries? Operational boundaries? Cross-Cutting Issues What guidance is currently available?
Operational Boundaries • What sources are required/optional? • What is a facility? • Geographic? • Defined by reporter? • Defined by state? • What degree of aggregation is required? • Entity? • Facility?
Break-out Groups • Exploration & Production • NG Gathering & Processing Discussions will continue in the Roundhouse after lunch. Please meet back here at 2:45.
Next Steps • Is a protocol warranted? • If so, goal: Present for adoption/incorporation • NM mandatory reporting • CA Registry protocol • CARB mandatory reporting • TCR protocol • Please convey interest to Tom Moore
