ToggleGreenhouse Gas (GHG) Validation and Verification Guidance
GHG validation and verification are essential because greenhouse gas (GHG) emissions are considered a primary driver of climate change. To reduce emissions and meet international commitments regarding climate change, companies and organizations must implement strategies to measure and report their emissions. Validation and verification help ensure that the resulting emissions data is accurate and reliable, while also meeting regulatory requirements and international standards.
Validation focuses on evaluating the GHG monitoring plan, testing the suitability of the methodologies, assumptions, and boundaries used prior to the collection of emissions data (*ex-ante*). It is an initial process conducted to check the conformity and completeness of the data and GHG emissions calculation methodologies against applicable standards. This stage serves as an internal check to ensure the resulting data is accurate and defensible. The verification process can only begin once validation is complete. Validation examines:
- Methodological suitability: Are the methods chosen to calculate GHG emissions appropriate and aligned with standards such as ISO 14064?
- Validity of assumptions: Are the assumptions used in the GHG emissions calculations realistic and justifiable?
- Clarity of boundaries: Have clear boundaries—such as organizational and operational boundaries—been established for the GHG emissions calculations?
- Accuracy: Have the reported emission data been calculated correctly and are they free from errors?
- Completeness: Have all relevant GHG emission sources been accounted for and reported?
- Consistency: Are the reported emission data consistent over time and across units/divisions?
- Transparency: Are the reported emission data presented clearly and in an understandable manner?
- Freedom from material misstatement: Are the reported emission data free from significant errors that could mislead data users?
