Greenhouse gas emissions
verification – ISO 14064
Assurance supports regulatory compliance, strengthens ESG performance, builds stakeholder trust and identifies opportunities to improve data quality, reduce emissions and costs.
ISO 14064 independent third party assurance helps organisations to verify that their greenhouse gas (GHG) emissions and methodologies are accurate, complete and reliable, targets are realistic; and comply with ISO 14064.
Assurance supports regulatory compliance, strengthens ESG performance, builds stakeholder trust and identifies opportunities to improve data quality, reduce emissions and costs.
Inspired offers an assurance service that is aligned to the GHG Protocol and ISO 14064-criteria. This process is useful for providing independent third-party assurance to stakeholders and shareholders, and to meet voluntary and mandatory compliance requirements.
Inspired’s approach
The first step in our verification process involves an ISO 14064 Lead Verifier determining the level of assurance (limited or reasonable), scope (the organisation’s boundaries and facilities) of the assessment; the time period and the materiality threshold (for example, +/ 5% errors) for each GHG scope.
Subsequently, we plan the verification process by conducting a range of activities, such as a strategy analysis, a risk assessment and designing a data collection plan.
We will then proceed with the verification process by reviewing the GHG statement and conducting site visits. Depending on the number of site visits required, the verification process typically takes 4 – 6 months to complete.
Inspired produces a verification report, which outlines the verification process, presents conclusions and recommendations. The report will be reviewed by an independent reviewer who has not been involved in the verification process. This allows companies to demonstrate that their GHG emissions have been independently verified to ISO 14064.
Key deliverables
Depending on the number of site visits required, the verification process typically takes 4 – 6 months to complete.

Inspired produce a verification report, which will include a conclusion of the verification process and recommendations. The report will undergo a review conducted by an independent reviewer uninvolved with the verification process.

The report will allow companies to state that they have had their GHG inventory verified, with independent assurance, to the ISO 14064 GHG international standard.
