Teams look for a Persefoni alternative when the free Pro plan stops being enough, when the quote for Advanced arrives without a number, or when they want a vendor based in Europe. The choice usually runs between smaller European platforms with module-based plans and product-level tools for manufacturers.
Short answer: Looking for a replacement for Persefoni? Zevero, Carbmee and Cozero come first in our carbon accounting software ranking. The first three places are kept for challengers when the category has enough of them; the best-known brands come after that, in ranked order. Start with Zevero if you want a budget number before any sales call and only need Scope 1 and 2. These 11 products are all in Best Carbon Accounting Software in 2026; the notes say how each one compares with Persefoni.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.

Why buyers look past Persefoni
01
The free plan ends at one user
Pro is free with no trial period or time limit, but it is for a single user and the detailed GHG Metrics Reports are not part of it. A sustainability team of two or three people, or a finance colleague who must review the data, hits that ceiling early.
02
Reports and support are priced as add-ons
The pricing page lists the GHG Methodology Report, CDP and SECR reports, Scope and Category Analytics, Export Emissions Summary, Premium Support and an additional user as add-ons to Pro. Advanced carries no price and points to a demo, so the cost of a full disclosure set is known only after a conversation.
03
The product also serves lenders and investors
Persefoni sells a separate Financial Services line covering financed emissions for portfolio companies, and its pages show PCAF among the frameworks. For a manufacturer or services firm that is more surface than the job needs, and the homepage states no headquarters location for buyers who want a European contract partner.
you run a large corporate programme and want removals and clean power purchasing in the same tool

What each one does differently

Zevero
Not stated by the vendor · Published
Zevero prints a yearly figure for its Lite tier, which covers Scope 1 and 2, and the three larger plans are quoted. Unlimited users and onboarding come with every plan. Contracts run for a minimum of one year, there is no self-serve trial, and Lite leaves Scope 3 out, so a growing footprint outgrows it.
Switch from Persefoni if you want a budget number before any sales call and only need Scope 1 and 2.
Carbmee is a GmbH in Berlin and sells four quoted plans split by module, not by headcount. Core accounting, supply chain and product footprints sit at the small end; Studio, CBAM, EUDR, API access and forecasting come higher up. The pricing page gives no currency, limit or trial, so each figure is a quote.
Switch from Persefoni if your reporting needs CBAM or EUDR modules and you can pay for exactly those.
Cozero, also based in Berlin, consolidates all three scopes across several legal entities and ranks reduction scenarios by payback. It adds supplier outreach for Scope 3 data and API access. Its pricing address returned a 404 when we looked, so a demo request is the only way to learn what it costs.
Switch from Persefoni if a group with several legal entities wants a ranked reduction plan, not just a report.
Plan A was founded in Berlin in 2017 and has taken outside funding. Its GHG Protocol method is certified by TUV Rheinland, the company holds B Corp status and SOC 2, and AI-assisted modelling turns a footprint into targets. Costs are quoted on request and the site shows no plan structure.
Switch from Persefoni if an auditor or customer asks for a certified calculation method and security attestations.
Net0 publishes a two-plan split. Platform handles Scope 1 and 2 plus spend-based Scope 3 against more than 100,000 emission factors; Enterprise adds activity-based Scope 3 across all fifteen categories, API access and vendor outreach. Both are quoted. Its homepage now talks about custom AI systems for governments, so check its focus.
Switch from Persefoni if you want the upgrade path from spend-based to activity-based Scope 3 spelled out.
Greenly, from France, lists three named GHG tiers that differ in measurement depth, reduction planning and support, with CBAM and EUDR help and Scope 1-3 cover. Life cycle analysis is a separate plan, no tier shows a price, and an announced merger with Normative means you should confirm who signs the contract.
Switch from Persefoni if you want to compare named tiers before talking to sales and are based in France or nearby.
Ecochain does product life cycle assessment, not a company inventory. Its three plans are split by number of products assessed, from under 20 to over 200, and only the smallest bills monthly. A seven-day trial includes two expert calls but limits you to ten Ecoinvent datasets. Quotes shift with supply chain complexity.
Switch from Persefoni if what you need is a footprint per product and you can test it for a week first.
Carbonfact sells company accounting and per-product life cycle assessment as two offerings, each with unlimited users, and says it takes data from more than fifty connected tools. Reporting and decarbonisation planning cost extra, no trial is offered, and the site names no country, only a company called Kanso, Inc. in the footer.
Switch from Persefoni if a manufacturer needs product-level footprints and many colleagues need seats.
Sweep, based in Paris, measures, reports and plans cuts across Scope 1-3 and extends to wider ESG data. It is registered as an Entreprise a Mission under French law and appears in 2026 IDC and Verdantix analyst placements. Nothing is published on price, plans or trial, so scope is settled after a demo.
Switch from Persefoni if you want carbon and wider ESG data on one French platform and accept a demo-led sale.
Terrascope, with an address on Robinson Road in Singapore, bundles corporate and product footprints, supplier engagement, climate reporting and an energy, waste and water module. Its pricing page lists no plans, limits or integrations and offers one Book demo button, so every comparison happens in sales calls.
Switch from Persefoni if supplier engagement and an energy, waste and water module matter more than price transparency.
Watershed is venture funded, with offices on several continents, and states a library of 2.3 million emission factors plus a marketplace for removals and clean power. It publishes no pricing and sells to enterprises by contract. That scale suits a dedicated sustainability team more than a lone analyst.
Switch from Persefoni if you run a large corporate programme and want removals and clean power purchasing in the same tool.
Zevero: Lite covers Scope 1 and 2 at a printed yearly price with unlimited users, on a one-year minimum contract.
02
You report under CBAM or EUDR
Carbmee: Plans are split by module and the higher ones add CBAM and EUDR, quoted from Berlin.
03
You need a certified calculation method
Plan A: The GHG Protocol method is certified by TUV Rheinland, and the company holds SOC 2.
04
You want to assess individual products
Ecochain: Plans are tiered by product count and a seven-day trial includes two expert calls.
05
You want carbon and wider ESG data from a French vendor
Sweep: It covers Scope 1-3 and ESG data, and pricing follows a demo.
04
When Persefoni is still the right choice
Persefoni remains a sound choice for a team that wants to load real Scope 1-3 data on a permanent free plan before signing anything. Pro covers all fifteen Scope 3 categories and a report builder for CSRD, ISSB and CDP, and Advanced lists SOC 1 and 2 Type II, ISO 27001 and 27017, SSO and unlimited users. Lenders and investors in particular get a financed-emissions product from the same vendor.
05
What moving off Persefoni involves
01
Export your history before you rely on it
Pro keeps unlimited historical reporting years, but exporting the emissions summary is an add-on. Ask what you can take out, and in which format, before you rely on the data living only in Persefoni.
02
Emission factors and methods will differ
A new tool applies its own factor library and spend-based or activity-based method, so last year's total may shift when re-run. Re-calculate one reporting year in both tools and record the gap before you restate anything to an auditor.

Do any alternatives cover CBAM or EUDR?
Carbmee lists CBAM and EUDR modules and Greenly mentions help with both. Check the scope of each module in writing before buying.
