For companies

Know your footprint. Back up your claims.

GroCarbon gives your team one place to measure emissions across every site, report them clearly, and show buyers exactly how you got your numbers.

Measure emissions across your business

Add each site, subsidiary or vehicle fleet, and invite the people who know the numbers.

Everyone adds data for their own site and sees only what they need.
Covers the fuel you burn, the energy you buy and your supply chain (scopes 1, 2 and 3).
Each figure is matched to a recognised emission factor, with its source shown.
Lock the year once it’s checked. If something changes later, you can update it with a clear record of what changed.

Each activity sits next to the factor used to calculate it, so anyone can follow the maths: your team, an auditor or a buyer.

Choose from three types of claim, each worded to stand up to scrutiny.

GroCarbon checks every claim before it goes live, and some types also get an independent auditor’s sign-off.
Share it on a public page, on your own web address if you like, showing how you measured and who checked it.
Emission cuts and credits are shown separately, so the picture is clear.
If you withdraw a claim, its page explains why.

For emissions you can’t cut yet, buy and retire credits from projects near you.
