Every year, more companies are having their greenhouse gas data verified to meet different requirements. Greenhouse gas verification (GHGV) is when an organization engages an independent third-party practitioner to verify its greenhouse gas statement using standards such as ISO 14064-3. This engagement is intended to enhance stakeholder confidence in the organization’s conformance to a set of defined criteria for evaluating, measuring and reporting GHG emissions. Our experts have put together this list of advice to help companies prepare for the GHGV process.
Top five tips:
1. Methodology document
The GHGV process includes multiple documents, spreadsheets and invoices, which can contain complex formulas and in-depth estimation processes. Including a detailed methodology document that fully explains each calculation and estimation process used can decrease the risk of incorrect formulas, calculations and numerical errors. It also keeps all the information centralized, reducing communication errors.
2. Naming convention
A consistent naming convention is key to creating clarity within the GHGV process. If a building has multiple names, it is best to state this and only use one name throughout the documentation. Switching between naming conventions for buildings, meters or transportation can prolong the process.
3. Units
As mentioned above, the GHGV process requires extensive math and formulas. For accurate documentation, it is vital to include units for every number within any piece of information. Units also show that formulas have been carried out correctly.
4. Formulas
Formulas are needed for simple calculations, such as aggregating monthly data into yearly data, and more complex calculations, like REC’s data. Regardless of the formula, it is important to always document what formulas are being used. This allows for ease in rechecking work.
5. Document the unknown
The last and final tip is to document the unknown. It is always better to document what is unknown than to estimate or guess and be incorrect. When unknowns are documented, UL Solutions can work with you to make them known.
