ISO 14064 — measuring and reporting emissions
Customers, banks and public contracting authorities increasingly ask for a number, not a statement. ISO 14064 sets out how greenhouse gas emissions are calculated so that someone else can verify them.
What is ISO 14064?
ISO 14064-1 governs organisation-level quantification. Emissions are divided into scope 1 (direct — combustion in your boilers and vehicles), scope 2 (purchased energy) and scope 3 (the value chain — purchasing, transport, waste, travel). The first three steps are not measurement but decisions: organisational boundaries, reporting boundaries and the base year against which everything is compared.
The result only carries weight once it is verified by an independent body under ISO 14064-3. That is why the work is done from the start so that every figure can be traced to an invoice, meter reading or delivery note — otherwise the verifier cannot confirm the number. With ISO 50001 you also get the other side: 14064 shows how much you emit, 50001 reduces the consumption the emissions come from.
When is ISO 14064 required?
When an EU customer, bank or fund asks for emissions data, usually as part of a sustainability questionnaire or financing conditions. It increasingly appears in public calls and in large buyers' requirements for their suppliers.
The other reason is your own: if you use a lot of energy, the emissions calculation shows where the money goes. That is why ISO 14064 and ISO 50001 often go together.
Road to a verified report
Most of the work is collecting data — the calculation is the easier part:
Who verifies the report
The report is checked by a verification body — an independent firm working to ISO 14064-3, usually accredited for this type of work. The result is a verification statement, not a management system certificate, and it states the level of assurance achieved. We do not verify what we have calculated ourselves — that would defeat the point of independence. Our part is to make the calculation and documentation robust enough to pass verification.
Scope of our support
A review of sites, equipment, vehicles and energy sources — and of the data you already have in accounting.
Calculating emissions by scope, with documented factors and assumptions.
A report under ISO 14064-1 in a form the customer or bank can use.
Organising the evidence and supporting you during verification, including responses to findings.
Related standards
ISO 14001 provides the system in which the data is generated, ISO 50001 the energy measurement, and ESG reporting is the most common reason you need the calculation at all.
Industries where this standard is most often required:
Training for teams that collect energy and emissions data — calculation boundaries, scopes 1, 2 and 3, emission factors and verification preparation. Delivered at your premises, online or as a combination of both.
ISO 14064 — frequently asked questions
What is scope 3 and do we have to calculate it?
These are emissions in the value chain — purchasing, transport, waste, business travel. They are not always mandatory, but customers ask for them more and more, so at least the significant categories are included from the start.
Do we need it if we have ISO 14001?
ISO 14001 requires you to manage your impacts, but it does not prescribe how emissions are calculated and reported. ISO 14064 provides exactly that calculation and the possibility for someone independent to confirm it.
Is it the same as an ESG report?
No. ISO 14064 covers greenhouse gas emissions, while an ESG report is broader — it also covers social and governance issues. ISO 14064 data is usually its environmental part.
How much does an emissions calculation cost?
It depends on the number of sites, the types of energy and how much of the data is already in order. Send basic consumption data for an indicative quote.

ISO 14064 is the same standard wherever you certify it — what differs is the designation, the accreditation behind the certificate and what your customers ask for.
In the European Union the standard is adopted with an EN prefix, and what your buyer in the Netherlands, Germany or France looks at is not the prefix but the accreditation behind the certificate: a body accredited by a signatory of the international recognition arrangement (Global Accreditation Cooperation, formerly IAF) is recognised in other markets too. What EU partners and EU regulation expect is on the page about the EU market.
For companies with customers in the United States — supplier audits, security questionnaires and how ISO sits alongside SOC 2 — see the page about the US market.
Wherever your customer is, we run the project remotely in English — over Teams, WhatsApp or Viber, with documentation and records in English — and on site when that is easier.
