Special audits

Verifying the unexplored

ESG topics that haven’t been verified before. We’ll find a way.

What we do

Tailored ESG audits.

Not every ESG challenge fits a standard approach. A Special Audit gives you independent assurance on a single topic, a specific risk or a defined set of KPIs. Clear, independent and focused on what matters to your organisation.

Verify ESG requirements

When a customer, bank, investor, regulator or supply chain partner requires assurance on  a specific ESG topic.

Objective performance review

When you need independent evidence for a single ESG topic or a limited set of indicators.

Assess external parties

When you want to assess a supplier, contractor or other third party.

Targeted Certainty

When you need assurance without the scope of a full sustainability report.

No standard approach.

Flexible

Tailored to your specific needs. Never a standard checklist.

Confidence

Built on the recognised AA1000 Assurance Standard.

Clarity

Clear reports with findings, risks and practical recommendations.

Trusted

A personal approach backed by a proven track record in verification.

Examples of special audits

Special audit

Verification of ESG Tools and Calculation Models

Organisations increasingly rely on carbon calculators, footprint tools and impact dashboards. But how do you know the results are accurate?

What we do

01

Assess data logic, calculation methods, assumptions and emission factors.

02

Review the underlying data sources and methodology.

03

Validate that the results are accurate, consistent and reproducible.

Results

An independent assurance statement confirming that your tool is accurate, reliable and fit for purpose.

Special audit

Social Audits for Contractors and Supply Chain Partners

Want to be sure work across your supply chain is carried out responsibly? We assess contractors, subcontractors and staffing agencies against recognised labour and human rights standards.

What we do

01

Policies & governance: Code of Conduct, human rights and compliance processes.

02

Employment practices: CLA-agreements, wage payments, social security contributions.

03

Working conditions: Health and safety, work permits and training requirements.

04

Human rights risks: Modern slavery, false self-employment and child labour.

05

A clear audit report with compliance findings, identified risks and practical recommendations.

Special audit

CDP Assurance: Carbon Footprint and Claims Verification

CDP submissions depend on robust data and reliable evidence. Especially when your score depends on the strength of your supporting information.

What we do

01

Verify your carbon footprint, including Scope 1, Scope 2 and, where applicable, Scope 3 emissions.

02

Assess methodologies, emission factors, allocation methods and underlying assumptions.

03

Review and verify claims made in your CDP questionnaire (net-zero commitments, carbon neutrality and climate risk assessments).

04

Check all submitted information for completeness, accuracy and transparency.

Results

Reliable evidence-based CDP disclosures that strengthen scores and reduce assurance risks.

Special audit

KPI assurance for sustainable finance

More and more Sustainability-Linked Loans (SLLs) tie interest rates to sustainability performance. That means those results need to be verified independently.

What we do

01

Verify agreed KPIs, such as carbon emissions, energy efficiency, waste reduction and social performance.

02

Assess KPI definitions, data quality, calculations and supporting evidence.

03

Provide annual verification, giving lenders the confidence to apply sustainability-linked pricing.

Results

An independent assurance statement confirming that the reported performance is reliable.

About us

Honestly forward

We verify with a genuine understanding of your business. Because understanding is a kind of psychological fuel. It lowers defences. That makes honesty possible, allowing us to establish more clearly where you currently stand. And that's essential to move forward.

Frequently asked questions

Want to know more about how we help companies become more sustainable?

  • What makes Fira different?

    We combine independent assurance with a genuine interest in and understanding of your business. We don’t just come looking for mistakes to point fingers at. We take the time to understand how your organisation works before we assess it. That deeper understanding leads to better insight. And we believe that’s the foundation of clear, independent sustainability assurance.

  • Why does independent sustainability assurance matter?

    Because sustainability has become part of doing business. Claims need evidence. Customers, banks, investors and business partners want confidence that your sustainability claims hold up. Our independent assurance provides that confidence, without passing judgment.

    We don’t provide assurance to judge, but solely to establish the facts with clarity, so you know exactly where you stand. The result? Greater trust. Greater credibility.

    Customers, banks, investors and supply chain partners increasingly expect evidence. Organisations that can’t substantiate their claims risk losing trust and damaging their reputation.

  • Does Fira only provide assurance, or do you also help organisations improve?

    We're an organisation that measures and verifies sustainability: assurance, in other words. But we do it in a way that encourages improvement. We verify with a genuine understanding of your business. Understanding lowers defences. That allows us to verify your sustainability performance even more thoroughly. Which means you can improve more effectively, make better choices, and take on sustainability yourselves.

  • What type of organisation does Fira work with?

    We provide assurance across every industry and sector. Our ideal clients are organisations that take sustainability seriously and want to communicate about it honestly. From SMEs to large enterprises. Whether you’re just getting started or already well advanced, independent insight always adds value.

  • What does “Honestly forward.” mean?

    It means real progress starts with knowing exactly where you stand. Not with polished stories or empty claims, but with honest insight. Because honest insight creates direction. It builds trust. And it gives organisations the confidence to keep moving forward.

  • How much does sustainability assurance or a TIM Rating cost?

    Every sustainability assurance engagement and every TIM Rating is different. That’s why we first take the time to understand your organisation and your objectives before preparing a proposal. You’ll receive that proposal within one working day of our introductory meeting, so you’ll know exactly what to expect.
