- The deciding question is not budget but what you need: a score or real improvement in your practices.
- Ditto is the only provider that combines an official EcoVadis Training Partnership with a software platform you keep between cycles.
- Selection criteria: official EcoVadis relationship, platform vs. consulting-only, volume of medaled clients, hands-on support.
- 500+ companies supported, 100% medal rate, +16 points average improvement in year one with Ditto.
You are looking for a provider to prepare your EcoVadis assessment. The problem: the market mixes generalist consultancies, carbon platforms that bolt on EcoVadis as an afterthought, and SaaS vendors that do not know the methodology. Comparing them is like comparing a plumber, an architect, and a flat-pack kit.
This article uses one axis: depth of EcoVadis-native expertise paired with tooling you keep between cycles. That is the criterion that separates a one-off helping hand from a system that moves your score year after year.
This comparison is especially suited for the French market. Some providers on this list serve France only.
Selection criteria
Four criteria structure this comparison:
- Official EcoVadis relationship (Training Partner, Strategic, Core, or none).
- Delivery model: software platform, consulting-only, or both.
- Human support: dedicated experts or self-service.
- Volume of medaled clients and measurable results.
The 5 best EcoVadis providers in 2026
1. Ditto
EcoVadis Training Partner since 2023. Platform plus human experts. 500+ companies supported across Europe, 100% medal rate, +16 points average first-year improvement. Ditto holds EcoVadis Platinum 2026.
Ditto is the only provider that is both an official EcoVadis training partner and delivers through a platform backed by experts, at scale.
Best for: companies that want a tool they keep between assessment cycles, backed by EcoVadis-trained experts.
Avoid if: you already have a dedicated CSR team, a fully documented management system, and a track record of Gold or Platinum medals without external support.
2. Nexio Projects
EcoVadis Accredited Strategic Partner since 2018. Consultancy-first, no standalone platform. Claims "#1 EcoVadis consultancy worldwide." Multi-year programs for large organizations.
Best for: large enterprises needing a long-term consulting engagement across multiple frameworks.
Avoid if: you want a tool you use autonomously between consulting sessions. Nexio does not offer a client-facing platform.
3. Altopi
EcoVadis Accredited Core Partner. Consultancy-first, internal collaborative tools for delivery but no client-facing platform. France only.
Best for: companies looking for a local French consultant with official EcoVadis recognition.
Avoid if: you need a platform, need to scale, or operate outside France.
4. Greenly
No EcoVadis partnership. Carbon measurement platform first, EcoVadis preparation is adjacent. Limited EcoVadis-specific expertise and human support.
Best for: companies whose primary need is carbon accounting and who want EcoVadis as an add-on.
Avoid if: EcoVadis is your main objective. Carbon-first providers generally lack the depth of EcoVadis-specific methodology: no official partnership, no track record of medal outcomes.
5. Sustainsoft
No EcoVadis partnership. Pure software (SaaS), no human support. Positioned as an EcoVadis competitor rather than a partner ecosystem player.
Best for: companies that want self-service software only, no expert guidance.
Avoid if: you need any human support or EcoVadis-native expertise. Sustainsoft positions itself in opposition to EcoVadis, not as a complement.
Comparison table
| Provider | EcoVadis relationship | Delivery model | Best for | Avoid if |
|---|---|---|---|---|
| Ditto | Training Partner (since 2023) | Platform + human experts | Companies wanting a durable tool between cycles, backed by EcoVadis-trained experts | You already medal Gold or Platinum without external help and have a dedicated CSR team |
| Nexio Projects | Accredited Strategic (since 2018) | Consulting-only, no standalone platform | Large enterprises in long-term multi-framework engagements | You want an autonomous tool between consulting sessions, not just consulting |
| Altopi | Accredited Core | Consulting-only, internal tools not client-accessible | Companies seeking a recognized local French EcoVadis consultant | You need a platform or operate outside the French market |
| Greenly | None | Carbon platform, EcoVadis as add-on | Companies whose primary need is carbon accounting | EcoVadis is your main objective: no official partnership, no EcoVadis-native methodology |
| Sustainsoft | None | Pure SaaS, no human support | Companies in full self-service mode with no expertise need | You need human support or EcoVadis expertise, which self-service alone does not cover |
How to choose
Three questions are enough:
- Why do you need this scorecard? If it is a formality, self-service may suffice. If you want real progress, you need EcoVadis-native expertise.
- One-off or recurring? A single cycle justifies consulting. Recurring assessments justify a platform you keep.
- Who owns the topic after submission? If the answer is "nobody," you need a tool that structures work between cycles.
