Services / Advisory
Get your emissions data organized and ready to use.
Build reliable information, clear methods, and a repeatable process your team can operate after the engagement.
When this helps
Different sites use different spreadsheets. Supplier estimates are hard to explain. A reported number cannot be traced back to its source.
What this helps you decide
Determine what the inventory includes, how estimates are made, and which controls make the information suitable for its intended use.
What you receive
- Documented organizational and reporting boundaries, baseline, methods, and assumptions.
- Greenhouse gas inventory and calculation files, with an evidence index and source-to-output traceability.
- Data-owner map, collection templates, review controls, and reporting calendar.
- Data-quality and improvement register, operating instructions, and knowledge-transfer sessions.
How we work
Map existing sources, systems, and owners. Agree accounting methods, reconcile the inventory, and strengthen controls where needed. Run the process with your team and connect the results to reporting and management decisions.
Technical approach and standards
Work can cover greenhouse gas (GHG) inventories using the GHG Protocol Corporate Standard: direct emissions (Scope 1), purchased energy (Scope 2), and relevant value-chain emissions (Scope 3). ISO 14064-1-aligned quantification and reporting may be included where relevant. For organizations with financial portfolios, financed-emissions work can use applicable Partnership for Carbon Accounting Financials (PCAF) methods. The engagement identifies the standard, edition, asset classes, and limitations.
Scope and boundaries
Start with the reporting purpose, applicable requirements, and reporting year—not simply the data available. Under the GHG Protocol Corporate Standard, choose and consistently apply an organizational consolidation approach: equity share, financial control, or operational control. Map entities, sites, joint ventures, and leased assets against that approach.
Then set operational boundaries: direct emissions (Scope 1), purchased electricity, steam, heat, and cooling (Scope 2), and value-chain activities (Scope 3). Apply the Scope 2 Guidance, including both location-based and market-based reporting where operations are in markets with product- or supplier-specific contractual information. Check those instruments against the Scope 2 Quality Criteria; purchasing certificates does not by itself demonstrate a reduction in physical emissions. Screen all 15 Scope 3 categories, apply their minimum boundaries, and explain exclusions. Record the base year, recalculation policy, methods, assumptions, and data gaps; address missing data through appropriate estimation where possible, and transparently justify any exclusions.
For financial portfolios, apply the relevant PCAF Standard alongside the inventory boundary. PCAF Part A (third edition, 2025) requires operational or financial control consolidation, rather than equity share. Identify lending and investment activities outside that control boundary for Scope 3, Category 15, then document asset classes, attribution methods, investee emissions coverage, and data-quality scores. Disclose portfolio coverage and justify exclusions. Facilitated and insurance-associated emissions have separate PCAF standards.
Agree advisory deliverables separately in the proposal, including supplier outreach, software changes, and historical recalculation where needed. A limited engagement does not redefine the required inventory boundary. Inventory preparation and readiness support do not provide independent assurance.
Who should be involved
Finance, sustainability, operations, facilities, procurement, data or technology teams, and the internal control owner.
