Scope 1
Direct emissions from sources your organisation owns or controls, such as fuel use, vehicles and refrigerant losses.
Verification services
GHG verification and assurance. A clear scope, a useful result.
We independently assess organisational greenhouse gas inventories prepared using the GHG Protocol or ISO 14064-1, with verification using ISO 14064-3.
What we verify
Your organisation’s emissions, within an agreed boundary.
Scope 2
Emissions from purchased electricity, heat, steam and cooling. We agree the relevant location-based and market-based reporting coverage.
Scope 3
Agreed value-chain categories, including the methods, assumptions and supporting information used to calculate them. More about Scope 3
We do one thing
Independent verification. No conflicts. No compromises.
We do one thing: independent ISO 14064-3 verification of greenhouse gas inventories. No management system certifications. No advisory services. No software commissions. No referral fees. No conflicts of interest, so when we issue a verification opinion, it means something.
Some providers combine verification with consultancy, software or paid referrals to partners. We don’t, so our only interest is getting your verification right.
Your deliverables
Know what you are buying.
A clear plan
An agreed scope, timetable, assurance level and fee, with responsibilities set out before work begins.
Free readiness review
Documented early findings and time to act on them. It is free when you commission verification and is not added to your fee.
Verification statement
A formal statement setting out what was verified, against which criteria and to what level of assurance, with a findings report to help you improve next year.
The final findings report is provided regardless of the outcome. Where the evidence supports a confirming conclusion, we issue the relevant verification statement and certificate. The statement explains what has and has not been covered.
The process
From available data to a completed engagement.
Agree the scope and fee
We agree your reporting period, boundaries, the emissions to be covered, the assurance level and your deadline, then confirm the fee.
Your free readiness review
We review the information you already have, from part-year or last year’s data, months before your deadline. Your team gets private, documented feedback to act on at its own pace.
Formal verification
We verify the complete reporting period, an independent reviewer checks our work, and you receive your verification statement and findings report.
Your team or independent adviser addresses findings. We then assess the resulting evidence.
Most start with limited assurance
Limited or reasonable assurance: which do you need?
ISO 14064-3 defines two levels of assurance. Both are legitimate. The right choice depends on your reporting obligations, what your stakeholders expect and the level of scrutiny your data will face.
Limited assurance
The standard for most voluntary reporting, CDP submissions and ESG disclosures. It uses enquiry, analytical procedures and targeted data testing to give a moderate level of confidence that your GHG statement is free from material misstatement. It results in a negative-form conclusion: “nothing has come to our attention that causes us to believe the GHG statement is materially misstated.”
Cost-effective, proportionate and widely accepted, including for CDP.
Reasonable assurance
A higher level of confidence, for regulatory compliance, mandatory disclosures and situations where the data will face detailed external scrutiny. It involves extensive data testing, source-level cross-checking and detailed methodology review. It results in a positive-form conclusion: “In our opinion, the GHG statement is fairly stated in all material respects.”
Reasonable assurance typically requires 50–100% more audit hours than limited assurance. It is a high level of assurance, not absolute assurance.
Preparation and fees
A manageable plan for your team.
What we’ll discuss
We’ll explore your reporting, available information and the people involved, then agree what evidence is needed. You do not need everything ready for the first call. What we’ll discuss
What determines the fee
Scope, categories, sites, countries, complexity, assurance level and timetable. The fee is for formal verification. Your readiness review is free and does not increase that fee; changes to scope are discussed before additional work.
Verification for CDP
An accepted standard. Relevant experience.
For CDP disclosures, we verify ISO 14064-1 organisational footprints in accordance with ISO 14064-3, a verification standard accepted by CDP.
Our verification statements have been accepted in previous CDP disclosures. We agree the reporting period, coverage and assurance level, then document the completed work in your verification statement.
Verification for your CDP disclosure · Our standards and credentials
Start with a 20-minute conversation.
You will talk to a verifier, not a salesperson. Tell us why you report, which scopes you need verified and when you need the statement, and ask whatever you need to. You do not need a finished inventory. If you go ahead, the person you speak to leads your verification.
No obligation, and no sales pitch
