Formist vs Greenly
Formist vs Greenly
Greenly and Formist cover much of the same EU ground: GHG inventories, CSRD, CBAM, the EU Taxonomy and product footprints. The difference is shape. Greenly is a carbon management platform with its own AI agents. Formist is an agent you reach from Claude, ChatGPT or your team’s chat, which reads your documents and produces the filing.

When Greenly is the better choice
- You want a full LCA product and dedicated pages for many EU rules, from EUDR to packaging.
- You want named agents inside one platform, and a workflow that gives your auditor access.
- You prefer a platform with a team behind it to a tool you run yourself.
When Formist is the better choice
- Your team already works in Claude or ChatGPT and wants the filings to come from there.
- Your source material is documents, not clean data: invoices, meter readings and shipping papers.
- You also need logistics emissions under ISO 14083.
Questions buyers ask
- Is Formist a Greenly alternative?
- For GHG inventories, CSRD, CBAM and the EU Taxonomy, yes. For a full product LCA programme, Greenly offers more: Formist’s LCA skill is a Tier 1 screening.
- What does “not listed on their site” mean?
- We read the page cited for that row and did not find the feature. It does not mean the product cannot do it. Ask the vendor if it matters to you.
- Can I try Formist?
- Yes. Get in touch through the contact page and we will set up a walkthrough with your own documents.
