ISO 14064: 5 Reasons to hire an auditor in 2025

Updated on
June 16, 2025

These are the 5 key reasons to have an ISO 14064 auditor in 2025:

1. You comply with internationally recognized standards
2. You strengthen the credibility of your ESG reports
3. You identify errors or deviations in your data
4. You facilitate certification and verification processes
5. You improve your emissions reduction strategy

Auditing under the ISO 14064 standard is not just a technical matter or another formality.

It is a necessary step if we want to understand, control, and report our emissions seriously and with data that holds up.

More and more companies are measuring their real impact because they know that if they don’t, they will fall behind.

And this is not just about complying with regulations, but about staying competitive in a market that is already changing.

Having an audit under this standard forces you to keep your data in order.

To know where your emissions come from, how they are being measured, and whether it all holds up under scrutiny.

Measuring without a clear or rigorous reference is a waste of time and money.
If we are going to do it, let’s do it right.

In this article, we will explore:
what an audit under ISO 14064 involves, why you should take it seriously, and how to prepare without losing your mind.

5 Key Reasons to Have an ISO 14064 Auditor

1. You Comply with Internationally Recognized Standards

ISO 14064 is a global reference.
If we want to do things right, it has to be on our radar.

Auditing under this standard ensures that we speak the same language that the market, regulators, and stakeholders demand.

There are no shortcuts if we want to play seriously.
And this applies to any sector or company size.

2. You Strengthen the Credibility of Your ESG Reports

It’s not enough to say we’re measuring emissions.
We have to prove we do it with solid data and verifiable criteria.

An independent audit gives weight to your information. Especially if you're preparing your EINF, aligning with the CSRD or any other regulation.

If you have no credibility, your data is worthless.

3. You Identify Errors or Deviations in Your Data

Errors happen, especially when there is a lot of data involved.
But if we don’t catch them in time, we can make poor decisions.

An auditor helps us see what we’re missing.
Small things
that can end up creating major deviations in our total emissions.

Better to catch it now than to explain it later.

4. You Facilitate Certification and Verification Processes

There are more and more regulations that require us to prove what we report.
And external verification is part of the game.

If we already have an audit under ISO 14064, the rest of the process is much smoother.

It’s not just about compliance, it’s about doing it with less friction and fewer surprises.

5. You Improve Your Emissions Reduction Strategy

Auditing is not just about reviewing.
It’s also about understanding where we’re failing.

With clear and well-structured data, we can make better decisions.
And that translates into a more effective strategy to reduce emissions.

Because it's not about measuring for the sake of measuring.
It's about changing things.

What is the ISO 14064 Standard and Why Does It Matter?

ISO 14064 defines how to quantify, report, and verify greenhouse gas emissions.
Nothing more, nothing less.

It is a clear guide for measuring with rigor, without shortcuts, and without excuses.

If we want sustainability to be a strategic lever, this standard is one of the key starting points.
And yes, it is valid for any sector, country, or type of organization.

It's not just about complying with regulations.
It's about knowing where we are and where we can go.

When Does It Make Sense to Conduct an Audit Under ISO 14064?

If You're Going to Report Under Demanding Regulations

CSRD, EINF, SBTi, Taxonomy
All these frameworks require data that you can prove.

And if you're going to play in that league, you need an audit that backs up your numbers.
Without it, you’re going to be off the map.

If You Already Have an Emissions Inventory and Want to Validate It

Measuring is the first step, but validating is what really counts.
An audit ensures that everything you've calculated is properly done.

This is crucial if you want your reports to have weight and be recognized by third parties.

If You Want to Detect Errors Before It's Too Late

The larger your data volume, the higher the risk of errors.

An audit not only validates, it also corrects and refines.
It is a deep review that allows you to make decisions with confidence.

If You're Preparing for a Strategic Shift

Are you planning to invest in efficiency, change processes, or launch a new sustainability plan?

Conducting an audit beforehand gives you a real diagnosis.
That way, you're not going in blind and you focus your efforts properly from the start.

What Is the Role of an ISO 14064 Auditor?

Evaluation of Methodology and Data

The auditor reviews how we're measuring our emissions.
That includes the methodology, data sources, and criteria used.

It’s not just a technical check.

It’s about ensuring that what we claim has a solid foundation, and that we're following an approach aligned with the standard.

Because if the data is flawed from the beginning, nothing else matters.

Review of Organizational and Operational Boundaries

Here the auditor analyzes how far the measurement goes.
What parts of the company are included and how those boundaries are defined.

This step is crucial to make sure the information makes sense and is comparable.
Without it, we might be hiding emissions without realizing it.

We can’t manage what we’re not measuring correctly.

Verification of GHG Emission Calculations

The auditor validates the numbers.
Plain and simple.

They check if the emission factors, formulas, and conversions are correctly applied.

This ensures that our figures reflect reality.
No inflating or polishing results.

And if there are errors, it’s better to find them now than after publication.

What You Need to Have Ready Before an ISO 14064 Audit

1. Updated Emissions Inventory

Without data, there is no audit.

The first step is to be clear on what emissions you're measuring, where they come from, and how you're calculating them.

This includes direct and indirect emissions, from energy consumption to transportation or product usage. It’s the only way to get an accurate Carbon Footprint.

Everything must be well defined, categorized, and aligned with the scope you're reporting.

2. Clear and Documented Methodology

It’s not enough to have numbers.
The auditor will review how you obtained them.

You need a well-explained methodology, aligned with ISO 14064.
No assumptions. No shortcuts.

Each method, formula, and factor must be justified and traceable.

This is what allows your emissions inventory to be credible and defensible under external review.

3. Traceable Data Sources

Everything you report must be verifiable.
Invoices, consumption logs, calculations…

The more organized and traceable this information is, the less friction there will be during the audit.

And everything will go much faster.

If the auditor asks “where did this come from?”, you must have the answer.

4. Defined Organizational Boundaries

It must be crystal clear which part of the company is being audited.
You can't make arbitrary exclusions just to make the numbers look better.

Defining the boundaries from the beginning helps avoid inconsistencies and errors later on.

This includes specifying:

  • Which facilities are included

  • What activities are measured

  • Which subsidiaries or locations are part of the scope

5. A Team That Knows What It's Doing

You need an ESG responsible or someone who really understands the data.

The auditor is not there to do the job for you, but to verify it.
And if there's no one to explain how things were done, everything gets complicated.

Good audits depend on good preparation and informed teams.

Why Auditing Under ISO 14064 Is Becoming More Relevant

Increased Regulatory Pressure: CSRD, EINF, EU Taxonomy

Regulations are evolving, and they demand stronger data.
It's no longer enough to say “we measure”, we have to prove it.

CSRD, EINF, and the EU Taxonomy make it clear: if you're reporting, it must be verifiable.

Auditing under ISO 14064 prepares you for all this, without last-minute stress.

Demands from Clients and Investors

We’re not the only ones looking at our data.
More and more clients and investors want certainty, not promises.

Having your emissions audited builds trust and gives you a competitive edge.

If you're not transparent, someone else will be.
And they’ll be ahead of you.

Need for Transparency Within the ESG Framework

ESG has become a key criterion for evaluating a company.
And without transparency, there is no trust.

Auditing your emissions is part of building that transparency.

It all starts with ESG data that is reliable and accessible.

And if we want all this effort to mean something, we need reliable, up-to-date, and centralized data.

That’s exactly what we provide at Dcycle:
we're not auditors or consultants, we're a solution to gather and manage all your ESG information in one place, no matter how you intend to use it.

Who Can Audit Under ISO 14064 and How to Choose the Right One?

Types of Auditors and Verifying Bodies

Not just anyone can audit under this standard.
It must be a recognized entity, with real experience in emissions verification.

There are different types of auditors:

  • Individual auditors

  • Verification companies

  • Accredited organizations

The key is that they have:

  • Traceability

  • A clear methodology

  • And truly know what they're doing

We’re not looking for a fancy stamp.
We’re looking for data that holds up to serious analysis.

3 Criteria to Select a Reliable Auditor

First:
They must be accredited and have experience in your sector.
Not all auditors are suitable for all cases.

Second:
They must have a deep understanding of the ISO 14064 standard and of the requirements of current regulations like CSRD or EINF.

Third:
They must be clear in their processes and explain what they will review.
No technical jargon, no unnecessary detours.

Transparency in the auditing process is as important as the audit result itself.

How Often Should You Conduct an ISO 14064 Audit?

There is no fixed frequency, but the usual practice is to audit annually or every two years.

It depends on:

  • The volume of emissions

  • Whether you're reporting to regulators

  • The use you give to your emissions data

The most important thing is that audits are not seen as a formality, but as part of a continuous improvement cycle.

Regular audits help you:

  • Detect changes in your emissions

  • Validate new methodologies

  • Ensure long-term consistency

Skipping audits for years only increases the risk of errors, and undermines confidence in your reports.

Frequently Asked Questions (FAQs)

What Companies Are Required to Apply ISO 14064?

No company is legally required to apply this standard.

However, if you report under frameworks such as CSRD or EINF, they will demand it from you, one way or another.

It’s not a direct legal requirement, but it is the most solid way to prove your data is trustworthy.

So while technically optional, it’s practically essential for any company that wants to report emissions seriously.

What’s the Difference Between an Internal and External Audit?

An internal audit is done in-house, with your own team or with some support.
It helps to detect errors before publishing data.

An external audit is carried out by a third party and has real value for the market and for regulators.

If you want your report to be taken seriously, you need both types of audits:

  • Internal, to improve and control

  • External, to validate and certify

Can an Entire Company Be Certified Under ISO 14064?

No. ISO 14064 does not certify companies.
It certifies the calculation of greenhouse gas emissions.

What it validates is the quality of the inventory and how it’s reported.

In other words: It certifies the data, not the organization.

This is a common misconception, but it’s crucial to understand:

You are not "ISO 14064 certified" as a company, your emissions data and calculations are what can be verified under the standard.

How Long Does a Typical Audit Take?

It depends on the size of the company  and how organized your data is.

It can range from a few weeks to several months.

If your ESG information is already structured and ready, the process is much faster, much smoother, and much less expensive.

Preparation is everything.

What Are the Benefits of an ISO 14064 Audit for Investors?

It provides trust. Period.

If your emissions data is audited under a recognized standard, investors know they can rely on it.

And in a world where ESG is a key investment criterion, that makes a real difference.

At Dcycle, we help you have all your ESG data ready, clear, and well-structured.

We are not auditors, we are the solution that ensures all of this works without friction.

Whether it's for the investor, the regulator, or your own team, we make sure the information flows, and flows right.
