EcoVadis: preparing your evidence file step by step

Quick answer. Preparing an EcoVadis evidence file means gathering, theme by theme, dated and formalised documents at three levels: a written policy, an action taken, a measured result. The score runs from 0 to 100 and covers four themes (environment, labour and human rights, ethics, sustainable procurement). A medal is awarded by percentile rank. The challenge is not to redo everything, but to prove what already exists.

Many companies approach EcoVadis like a surprise exam and lose points not for lack of actions, but for lack of evidence. The questionnaire does not score intentions: it assesses what the company can demonstrate, with documents. A policy applied but never written down, a real action never measured, earn almost nothing. Preparing your EcoVadis evidence file means, first of all, turning your practices into documents you can produce.

This guide offers an operational checklist, pillar by pillar, of the evidence to gather, explaining the scoring logic so you can target effort where it pays. The aim: gain points on the basis of what already exists, without rebuilding your entire CSR policy. The approach fits a continuous-improvement logic recognised by public frameworks such as the ISO 26000 standard or the CSR resources of ADEME, which value traceability over statements of intent.

EcoVadis assesses a company's CSR performance across four themes:

• Environment: energy, emissions, waste, water, products and life cycle.
• Labour and human rights: working conditions, health and safety, social dialogue, diversity, training.
• Ethics: anti-corruption, competition practices, data protection.
• Sustainable procurement: integration of social and environmental criteria with suppliers.

Each theme is scored on three dimensions: policies (written commitments), actions (concrete measures implemented) and results (indicators, certifications, reporting). The overall score runs from 0 to 100. The questionnaire is not the same for everyone: its content is tailored to the company's profile, namely its size, sector and geography. A manufacturing SME and a consulting firm therefore do not answer exactly the same questions, because the environmental stake does not arise in the same terms.

For a medal to be conceivable, a theme left at zero drags down the whole: you need a base of evidence across all four, not excellence on a single one. This policies, actions, results logic is the reading grid to keep in mind for every document provided.

Since 2024, EcoVadis medals are no longer based on fixed score thresholds but on the company's percentile rank, compared with all companies assessed over the last 12 months:

Because the scoring is relative, the exact score thresholds are not published and may change from year to year: the same score may yield a different medal depending on the general level of the companies assessed. This ranking is made against all companies in the database, not within your sector alone. Non-medalled companies can obtain badges recognising an engaged approach. The practical consequence is clear: aim for steady, documented score progress rather than a fixed numeric threshold that does not stably exist.

For each theme, the reflex is to gather three levels of evidence: a written policy, an action taken, a measured result. The table below summarises what moves each pillar from the "intention" level to the "result" level.

On this last pillar, the evidence connects directly with the work described in our article on supplier clauses in sustainable procurement: a signed supplier code of conduct and an assessment tracking table count for more than a mere statement of intent.

1. Dated and formalised. An undated or never-validated document counts for little. A policy is worth its date, its management sign-off and its internal circulation (intranet, memo, read receipt).
2. Specific, not generic. A template copied without adaptation convinces less than a document, however short, that describes the reality on the ground: your sites, your trades, your figures.
3. Tied to a result. An action without an indicator remains an intention. Quantifying, even modestly (kWh consumed, training hours, number of suppliers assessed), moves a theme from policy level to result level. That is where the most cost-effective points are won.

A fourth rule, often overlooked: freshness. EcoVadis values recent evidence. A 2021 carbon footprint attached to a 2026 assessment weighs less than a 12-month consumption tracking. A recent, imperfect document beats a perfect but outdated one.

The classic trap is to try to produce everything the day before the assessment. EcoVadis rewards consistency: existing documents, dated across the year, beat a burst of policies all created on the same day, which jump out at an assessor. We advise building a living evidence file, fed continuously, rather than a binder assembled in a rush.

The other conviction, confirmed in most SME files: many companies underestimate what they already do. Waste sorting, the risk assessment document, annual reviews, supplier contracts often exist, but are tied neither to a written policy nor to an indicator. The work is less about doing more than about formalising and measuring what exists, then filing it in the right box of the questionnaire. That is exactly the ground of CSR and CSRD reporting support, which knows how to link the management data already held in the accounts (consumption, payroll, purchases) to the evidence the assessor expects. For an SME also bound by ESG reporting, the EcoVadis file and the sustainability report draw on the same documentary base: it is worth building them together.

A manufacturing SME of 40 employees receives an EcoVadis assessment request from a large client, a condition for remaining an approved supplier. Announced deadline: three weeks before the questionnaire is due.

Rather than starting from a blank page, the company inventories what exists. On the environment, it has electricity consumption tracking and waste sorting slips, but no written policy: it formalises a one-page environmental policy, dated and signed by management, and attaches its 12-month tracking. The theme moves from policy level to result level. On labour, the risk assessment document is up to date and the health and safety training certificates are archived: they simply need refiling. On ethics, it has a charter but no formalised whistleblowing line: the theme stays weaker and becomes the following year's improvement focus. On procurement, it attaches its supplier list and the CSR clauses in its framework contracts.

Result: a decent first score on the very first assessment, a clear roadmap (whistleblowing line, full carbon footprint, diversity plan), and an evidence file now fed continuously rather than rebuilt in a rush each year. The client maintains the approved-supplier status.

In practice: building your evidence file in six steps#

• Map what exists by theme before creating anything: policies, actions and indicators already available.
• Fill the cheap gaps first: put in writing what is already practised (a dated, signed one-page policy pays off quickly).
• Date, sign, circulate each document: without a date or sign-off, a piece of evidence loses most of its value.
• Tie each action to a figure, however modest, to reach the result level.
• Check freshness: discard outdated documents, favour the last 12 months.
• Keep a living file: open a shared folder fed all year long, not reconstituted on the eve of the next assessment.

• The neglected theme: aiming for excellence on one pillar while abandoning another is counterproductive; a weak theme drags down the overall score. A balanced base is better.
• Template copy-pasting: a generic policy not adapted to the company is easily spotted and earns little. Specificity beats volume.
• Outdated evidence: a document several years old weighs less than recent tracking. Freshness is part of quality.
• Policy/result confusion: filing a written policy with no indicator leaves the theme at intention level. No figure, no result level.
• Burst production: creating all your policies on the same day, just before the assessment, sends an unfavourable signal. Consistency counts.
• Forgetting procurement: it is the most often under-documented pillar in SMEs, even though a supplier code and an assessment log are quick to set up and connect with the work of preparing for CSR audit and certification.
