For suppliers

Your buyer asked for a product carbon footprint. Here's what to send.

Answer it with three things: a number per product, how it was worked out, and a file their system can read. You can have all three this week.

What your buyer is asking for

Buyers use a handful of terms. Here is each one in a line, and what answers it.

PCFProduct carbon footprint: the greenhouse gases from making, moving, using and disposing of one product, in kg CO₂e.Send: the footprint per product and the PDF report.
Scope 3 dataYour buyer reports the emissions of everything it buys (its Scope 3). Your product's footprint is their figure for it.Send: a footprint for each product they buy from you.
PACT fileA shared data format for product footprints, so your buyer's software can read your numbers without retyping them.Send: the PACT v3 data file.
ISO 14067The international standard for calculating a product carbon footprint and reporting how it was done.Ours is calculated in line with it, with a checklist on every footprint.
Primary dataData measured in your own factory, such as the electricity units on your bills, instead of published averages.Add a year of electricity units to replace the averages.
How it works

From a product page to a reply, in three steps

What you need

What it takes from you

The work is in finding your electricity bills, not in the method. We do the method.

1

A product link or a description

The name, the materials and their shares, the weight, the country it is made in.

2

A year of electricity units

From your factory's bills, for a footprint to send. Without them we use the published grid average for your country.

3

Ten minutes to check

Every value we read or assume is shown with where it came from. You confirm or change it before anything is calculated.

See where your product's footprint comes from

Your footprint shows which step matters most. For this T-shirt it is dyeing and finishing, not the cotton. That is where a change counts most.

What it costs

Free until 15 December 2026. Then you pay per finished footprint.

One published price for your region, no sales call. You pay only when a footprint is calculated, and get your money back if a run can't finish.

Questions

Questions suppliers ask

Will my buyer accept it?

Check what your buyer asked for. If they want a footprint calculated in line with ISO 14067, with its method, its sources and a PACT data file, this gives you all three. If they need a third-party verified study, it is a first step: it shows the result, the method and the gaps a verifier will look at.

Is the result verified or certified?

No. It is calculated in line with ISO 14067 and shows all its working, for sharing with business customers. Verification needs an accredited body; we don't sell that at launch.

Can I use it on my packaging or in adverts?

Not at launch. The result is for business-to-business use. Public claims need more evidence under EU and Indian rules.

What if I don't have my factory's data?

You still get a screening estimate from published data, clearly labelled as one. It is a fair start for a reply, and it shows which of your own figures would change it most.

How long does it take?

A first estimate takes about a minute from a product link. A footprint to send takes as long as it takes you to find a year of electricity units and check what we read.

What does it cost?

It is free until we launch on 15 December 2026. Then you pay per finished footprint, at one published price for your region. Join the waitlist to get the prices when they open.
