UNDERSTANDING INDEPENDENT ASSURANCE

What Is Verification & Validation?

Verification and validation are independent assessment processes used to evaluate information, statements, and claims against specified requirements.
Although closely related, they serve different purposes.
Verification evaluates a statement or claim based on historical information to determine whether it is materially correct and conforms to specified requirements.
Validation evaluates the reasonableness of assumptions, limitations, and methods supporting a statement about an intended future outcome.
Both processes involve systematic assessment, evidence evaluation, and an independent conclusion based on applicable standards and agreed criteria.
For organizations reporting greenhouse gas emissions, environmental performance, or sustainability-related information, verification and validation can strengthen the credibility of disclosed information and support confidence among regulators, investors, customers, and other stakeholders.

Frequently Asked Questions

Find answers to common questions about management system certification.

Verification evaluates a statement or claim relating to historical information to determine whether it conforms to specified requirements and is materially correct.
Validation evaluates the reasonableness of assumptions, methodologies, and limitations supporting a statement about an intended future outcome.
Both processes provide independent conclusions based on applicable criteria and supporting evidence.

Greenhouse gas verification is an independent assessment of a greenhouse gas statement to determine whether it conforms to specified criteria and is free from material misstatement.
The process may include evaluating emission sources, calculation methodologies, activity data, emission factors, organizational boundaries, and supporting records.
ISO 14064-3 provides requirements and guidance for verifying greenhouse gas statements.

The applicable standards depend on the type of information or statement being assessed.
Commonly relevant standards include ISO/IEC 17029, ISO 14065, and ISO 14064-3.
Other standards, such as ISO 14064-1 and ISO 14067, establish requirements for quantifying and reporting particular types of environmental information.

The duration depends on several factors, including the organization’s size, the complexity of the information being assessed, the defined scope, the availability of supporting evidence, and the applicable programme requirements.
WECERT reviews these factors during the application stage to determine the resources and estimated timeframe required.

Organizations generally need to provide their greenhouse gas inventory or statement, organizational and reporting boundaries, emission source information, calculation methodologies, activity data, emission factors, and relevant supporting records.
Additional information may be required depending on the applicable standard, verification criteria, and agreed scope.

Limited and reasonable assurance represent different levels of confidence associated with an assurance engagement.
Reasonable assurance generally requires more extensive evidence-gathering procedures to reduce engagement risk to an acceptably low level.
Limited assurance involves a different level of engagement risk and typically less extensive procedures.
The available assurance levels and their precise meaning depend on the applicable standard and verification programme.

No.
Management system certification assesses whether an organization’s management system conforms to the requirements of a specified standard, such as ISO 9001 or ISO 14001.
Verification evaluates a particular statement, claim, or set of reported information against specified criteria.
A verification statement is not equivalent to a management system certificate.
