[cg_add-class=heading-style-h4]In a Nutshell
- As of September 2026, the EcoVadis questionnaire typically takes 200 to 500+ hours a year to complete, spread across five distinct phases. Most of that time goes to internal data collection, not writing.
- Reusing last year's answers instead of starting over is the single biggest time saver, and it is also where most teams lose the most time today.
- A structured, centralized process with the right ESG software and experts, not more effort, is what separates a predictable questionnaire cycle from a scramble every year.
- Companies that run the questionnaire through Sunhat report cutting the time investment by up to 60 percent.
It is the second week of the EcoVadis cycle. You have this year's questionnaire open in one tab, last year's submission open in another, and a spreadsheet tracking which colleagues still owe you an answer. Your job is not just to answer more than a hundred questions. It is to find the right evidence, get five different departments to actually respond, and confirm that none of last year's documents have quietly expired.
It is tedious, it is easy to lose track of, and it happens every single year.
As of September 2026, companies typically invest 200 to 500 hours annually in the EcoVadis questionnaire process, some even many more. And all with no guarantee that the extra hours translate into a better score. Most of that time does not go to answering questions. It goes to finding, chasing, and re-formatting the evidence behind the answers.
The EcoVadis Questionnaire, in Plain Terms
The questionnaire and the rating are not the same thing. The questionnaire is what you submit: a set of questions and supporting evidence organized around four themes, Environment, Labor and Human Rights, Ethics, and Sustainable Procurement. The EcoVadis rating is what EcoVadis returns after its analysts review that submission, a score out of 100 and, above certain thresholds, a medal.
Every answer in the questionnaire is scored against three things. Do you have a formal policy? Can you show the actions that implement it? Can you report the key performance indicators that prove it is working? Get the structure of your answers right and the evidence gathering becomes far more manageable, because you already know what each answer needs.
How Long It Actually Takes, Phase by Phase
The 200 to 500+ hour range breaks down into five phases, and they do not take equal effort.
1. Evidence Preparation (20 to 50+ Hours)
Documents such as sustainability reports, policies, and supplier declarations exist, but rarely in the format EcoVadis expects. Most of this phase is revision, not creation: adding a signature, updating a date, aligning a document to EcoVadis's formatting rules.
2. Internal Data Collection (100 to 250+ Hours)
This is where most of the time goes. Information has to come from procurement, HR, and logistics, and the biggest obstacle is rarely a missing answer. It is not knowing who has it. Parallel requests across departments, inconsistent formats, and the wait for a reply are what stretch this phase out.
3. Approval (30 to 75+ Hours)
Reviewed answers still need sign-off, often from more than one stakeholder. Unclear ownership and missed deadlines are the usual cause of delay here, not disagreement over content.
4. Adjustments and Optimization (30 to 75+ Hours)
Collected data rarely fits EcoVadis's evaluation criteria on the first pass. Incomplete evidence and misunderstandings about what a question is actually asking both surface here, and both add another round of coordination.
5. Submission Preparation (20 to 50+ Hours)
Final documents have to be converted into an EcoVadis-compatible format and uploaded correctly, including file size and formatting requirements that are easy to overlook under deadline pressure.

Where Teams Lose Time, and What Actually Fixes It
Strip away the phase-by-phase breakdown. The actual time loss comes down to a handful of recurring problems, each with a specific fix.
- Starting from a blank page. Without a system that carries last year's answers forward, teams rebuild responses they have already written, for questions that barely changed. Sunhat's Proof AI suggests answers pulled straight from your last submission, so most of a question is already answered before anyone opens it.
- Chasing colleagues across departments. Data has to come from teams that do not own the questionnaire and are not tracking its deadline, which turns evidence collection into a series of follow-up emails. Assigning ownership and tracking status inside one shared workspace replaces the email chain, so contributors see what they owe without being chased.
- Documents that almost qualify. A missing signature or an outdated review date is a common reason a submission gets flagged, and so is a document stitched together from several sub-documents. Proof AI checks each document against EcoVadis's own formatting and validity rules before submission, flagging anything missing a logo, a date, or a signature, or nearing its expiry window.
- No safety net before submission. EcoVadis does not tell you when a document fails its requirements, so without an internal review step, the first anyone learns of a formatting problem is the final score. That review runs automatically inside the platform instead of depending on someone remembering to do it manually.
If your team does not have the hours to run any of this itself, Sunhat's Proof Services can take the EcoVadis assessment off your plate entirely instead.
Two Ways to Get Help
Unlike generic ESG software that treats the questionnaire as one more workflow to automate, Sunhat delivers the outcome, depending on what your team actually needs.
Proof Software, if your team runs the assessment and wants the manual work automated. Sunhat's Proof AI suggests answers from your past submissions, keeps documentation mapped to the right questions, and flags anything missing. See how the platform handles the EcoVadis questionnaire end to end.
Proof Services, if your team would rather the assessment were handled for them. Sunhat's certified EcoVadis experts run the questionnaire on your behalf,end-to-end. Your team is only involved where a decision needs a signature, unlocking the hours you would otherwise spend on it. See what a delivered EcoVadis assessment includes.
Sunhat customers see an average EcoVadis score increase of 12 points in their first year on the platform.
"We currently spend around 40 to 50% of our time on customer requests like EcoVadis. With Sunhat, we can improve efficiency by 25 to 30%, unlocking tremendous potential for my team."

The Bottom Line
The EcoVadis questionnaire will keep coming back every year for as long as your customers ask for it. What does not have to come back is the scramble: the blank-page starts, the department chasing, the documents that almost qualify. A structured process, built once and reused, turns an annual fire drill into routine work. You already have most of the answers. ESG Software, such as Sunhats Proof Platform helps you find them again, instead of writing them twice.

Frequently Asked Questions
ESG software, like Sunhat, addresses challenges such as finding/updating past answers, collaborating/delegating workload, mapping/maintaining documentation, adhering to document requirements, storing up-to-date documentation, and preventing response uncertainty. It streamlines the EcoVadis response process, saving time and improving efficiency.
Log in to the EcoVadis platform and work through the four topic areas: Environment, Labor and Human Rights, Ethics, and Sustainable Procurement. For each answer, confirm you have a policy, the actions that implement it, and the KPIs that prove it, then upload the matching evidence. Review everything for completeness and document validity before you submit.
Most of the time goes to internal data collection, not writing. Evidence has to come from departments that do not own the questionnaire, documents are rarely in EcoVadis's expected format on the first try, and approvals require sign-off from more than one stakeholder. Together, that is what stretches the process to 200 to 500 hours in a single cycle.
Yes. Sunhat's Proof Services run the assessment on your behalf, from evidence gathering through submission, so your team is involved only where a decision needs a signature. See what a delivered EcoVadis assessment includes.
