What is GHG Inventories?
Accounting and auditing the emissions in the atmosphere admitted from an institution that is expected to contribute to global warming.

Principles of GHG Accounting and Reporting
Relevance
Completeness
Consistency
Transparency
Accuracy
“You got to be very careful if you don’t know where you’re going, because you might not get
there.” - Yogi Berra
Provide business with information that can be used to build an effective strategy to
manage and reduce emissions; (WRI)
Provide information that facilitates business participation in different GHG programs,
including trading, registries, and other GHG reduction efforts; (WRI)
Contains the information that users—both internal and external to the company—
need for their decision making. An important aspect of relevance is the selection of an
appropriate inventory boundary that reflects the substance and economic reality of the
company’s business relationships, not merely its legal form. (EPA)
Question: what makes GHG accounting different from regular financial accounting? If it is
honorable (acceptable? expected?) for corporations to cut right to the bone with their financial
accounting practices, would we as consumers feel the same way if they followed that practice
with GHG accounting?
“Account for and report all GHG emissions sources and activities within the chosen
inventory boundary. Disclose and justify any specific exclusions.” - (EPA, GHG Accounting
and Reporting Principles)
Boundaries:
1) Organizational structures: control (operational and financial), ownership, legal
agreements, joint ventures, etc.
2) Operational boundaries: onsite and offsite activities, processes, services, and impacts.
Use consistent methodologies to allow for meaningful comparisons of emissions over
time. Transparently document any changes to the data, inventory boundary, methods,
or any other relevant factors in the time series. (WRI)
Address all relevant issues in a factual and coherent manner, based on a clear audit trail.
Disclose any relevant assumptions and make appropriate references to the accounting
and calculation methodologies and data sources used. (EPA)
Ensure that the quantification of GHG emissions is systematically neither over nor
under true emissions, as far as can be judged, and that uncertainties are reduced as far as practicable.

a. Availability bias: basing judgements on outcomes that are more easily remembered
COMPLEMENTARY STANDARDS, PROTOCOLS AND GUIDELINES
GHG Protocol: Product Life Cycle Accounting and Reporting Standard (2011)
GHG Protocol Corporate Accounting and Reporting Standard (2004)
GHG Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard (2011)
GHG Protocol for Project Accounting (2005)
GHG Protocol for the US Public Sector (2010)
GHG Protocol Guidelines for Quantifying GHG reductions from Grid-Connected Electricity projects (2007)
GHG Protocol Land Use, Land-Use Change, and Forestry Guidance for GHG project Accounting (2006)
Measuring to Manage: A Guide to Designing GHG Accounting and Reporting Programs (2007)
Information needs to be recorded, compiled, and analyzed in a way that enables internal reviewers and external verifiers to attest to its credibility. (WRI)
The information should be sufficient to enable a third party to derive the same results if provided with the same source data (WRI)
Achieve sufficient accuracy to enable users to make decisions with reasonable assurance as to the integrity of the reported information. (EPA)
The quantification process should be conducted in a manner that minimizes uncertainty. Reporting on measures taken to ensure accuracy in the accounting of emissions can help promote credibility while enhancing transparency. (WRI)
1. Unconscious
b. Representative bias: basing judgements on limited data and experience without looking at other relevant evidence

a. Motivational bias: an expert’s desire to influence the outcome or avoid contradicting prior positions on an issue
2. Conscious
b. Selection bias: the inventory agency selects an expert who tells them what they want to hear
Conclusion:
Accounting and auditing emissions in the atmosphere emitted from an institution
Used by all levels of government, corporations, regulators, scientists and general public
Main principles of GHG accounting and reporting:
Relevance
Completeness
Consistency
Transparency
Accuracy
Uncertainties exist!
Experts

QA/QC
•Number of sector-specific standards, protocols and guidelines available and are continually being introduced

Emissions are direct GHG emissions from sources that are owned or controlled by the entity. Scope 1 can include emissions from fossil fuels burned on site, emissions from entity-owned or entity-leased vehicles, and other direct sources.
Emissions are indirect GHG emissions resulting from the generation of electricity, heating and cooling, or steam generated off site but purchased by the entity, and the transmission and distribution (T&D) losses associated with some purchased utilities (e.g., chilled water, steam, and high temperature hot water).
Emissions include indirect GHG emissions from sources not owned or directly controlled by the entity but related to the entity’s activities. Scope 3 GHG emission sources currently required for federal GHG reporting include T&D losses associated with purchased electricity, employee travel and commuting, contracted solid waste disposal, and contracted wastewater treatment. Additional sources that are currently optional under federal reporting requirements, but are significant, include GHG emissions from leased space, vendor supply chains, outsourced activities, and site remediation activities.

To follow this method, the following information will be necessary, and should be available from the building’s property manager:
- Total building area;
- Area of company’s space;
- Total building electricity use (in kWh or MWh); and
- Building occupancy rate (i.e., if 75 percent of the building is occupied, then use .75)
(Area of Company’s Space ÷/ Total Building Area) x Total Building Electricity Use ÷/ Building Occupancy Rate = Approximate kWh or MWh Electricity Used
"Candidates will need to possess an in-depth knowledge of GHG fundamentals, climate change science principles, as well as generally accepted protocols, standards and methodologies. They will also be required to provide documented GHG and auditing experience as well as achieving a passing score on the certification exam."
