GHG Inventory and Accounting

A robust Greenhouse Gas (GHG) strategy begins with a technically sound inventory framework. We provide expert advisory services to help organizations align their Scope 1 and Scope 2 reporting with international standards, ensuring your carbon footprint is built on a foundation of accuracy, transparency, and consistency.

We go beyond traditional inventory approaches by integrating field-based emissions measurements wherever possible, improving the accuracy and reliability of reported data. In addition, we ensure strong alignment between GHG reporting frameworks and OGMP methodologies, enabling organizations to leverage existing methane data and streamline reporting across requirements.

ISO 14064 Framework Advisory

We guide your team through the complexities of the ISO 14064 standard. Our role is to help you define the necessary organizational and operational boundaries and establish the technical requirements for a compliant GHG inventory.

By expanding upon existing OGMP/MRV data, we help you integrate methane measurement into a broader GHG context using advanced modeling and data assumptions. This ensures consistency between OGMP reporting and corporate GHG inventories, reducing duplication and strengthening data integrity.

Scope of Advisory

We specialize in the quantification and strategic management of all regulated GHGs (including CO₂, CH₄, N₂O, NF₃, SF₆, and HFCs/PFCs), measured in tons of CO₂e.

Our advisory covers the identification, categorization, and continuous improvement of emissions data through measurement-informed methodologies, including:

Direct GHG Emissions & Removals

• Stationary & mobile combustion: Emissions from equipment and fleet operations
• Fugitive emissions: Advanced, measurement-driven quantification of methane and other leaked gases
• Process emissions: Emissions resulting from physical or chemical processing
• GHG removals: Identifying and quantifying sinks within your operational boundary

Indirect GHG Emissions (Scope 2 & Beyond)

• Imported energy: Emissions from purchased electricity, heat, or steam
• Transportation: Emissions from upstream and downstream logistics
• Product lifecycle: Indirect emissions from product use and value chain activities
• Other sources: Industry-specific indirect emissions

Measurement-driven improvement & data alignment

We actively support the transition from factor-based estimates toward measurement-informed inventories, enhancing credibility and enabling more precise emissions management.

By aligning GHG inventory practices with OGMP data frameworks, we help organizations:

• Integrate Level 4/5 methane data into corporate GHG reporting
• Ensure consistency between regulatory, OGMP, and corporate disclosures
• Reduce uncertainties through measured data and validated extrapolation methods
• Build a single, coherent emissions data architecture

Methodological rigor

Our advisory ensures that your inventory utilizes a hierarchy of reliable data sources and remains aligned with established methodologies from OGMP, EPA, API, and the IPCC.

We provide the technical support needed to utilize:

• Field-based measurement data (where available)
• Material balance data and engineering calculations
• Equipment-specific data and peer-reviewed literature
• Generic emission factors where direct measurement is not yet feasible
