How to Build an ESG Fact Vault From Scratch

Every ESG questionnaire you complete contains answers you will use again. The question about your environmental policy will appear in every questionnaire you receive. Your Scope 1 and 2 emissions data — same numbers, slightly different wording. Your modern slavery statement — identical every time until you update it. Rewriting the same content every time is how teams hit ESG questionnaire fatigue — a fact vault is the structural fix.

An ESG fact vault is a structured, centralised library of these reusable answers — your facts, policies, data points, and evidence documents, organised so that responding to the next questionnaire becomes a matching exercise rather than a writing exercise.

Around 80% of questions across different ESG questionnaires overlap. If you have answered 3 to 4 questionnaires, you have already written most of the content you will ever need. The problem is that those answers are scattered across old spreadsheets, email threads, and the memory of whoever filled them in.

What is a fact?

A fact is a self-contained, reusable answer to a common ESG question, with four components:

1. Answer text. A specific statement with numbers where relevant.
2. Keywords. Tags that help you find the fact — e.g. carbon, emissions, scope 1, scope 2, GHG.
3. Evidence references. Supporting documents that prove the claim.
4. Metadata. Last updated date, owner, next review date.

Example:

Category: Environment | Keywords: carbon, emissions, scope 1, scope 2, GHG, net zero Answer: "In FY2024/25, our Scope 1 emissions were 14.2 tCO2e (company vehicles and gas heating). Scope 2 emissions were 9.8 tCO2e (purchased electricity). Combined emissions have decreased 22% since FY2022/23. We maintain a 100% REGO-backed renewable electricity tariff and target a 30% total reduction from our FY2022/23 baseline by 2028." Evidence: Carbon footprint report, utility bills summary, renewable tariff contract Owner: Operations Manager | Next review: January 2027

That fact answers a question about emissions whether phrased as "What are your greenhouse gas emissions?", "Report your Scope 1 and 2 carbon data", or "Describe your carbon management approach."

Structuring your vault

ESG questionnaires consistently cover five areas. Structure your vault around these and you match virtually every questionnaire you receive.

1. Environment (8-15 facts): Energy consumption, carbon emissions, waste management, water usage, environmental policy, ISO 14001 status, carbon reduction plan, biodiversity.

2. Social (8-12 facts): Health and safety, accident rates, modern slavery due diligence, diversity and inclusion, gender pay gap data (mandatory for UK employers with 250+ staff under the Equality Act 2010 (Gender Pay Gap Information) Regulations 2017), training hours, employee wellbeing.

3. Governance (6-10 facts): Anti-bribery policy (Bribery Act 2010), whistleblowing, UK GDPR compliance, Cyber Essentials, business ethics code, ESG oversight.

4. Supply chain (4-8 facts): Supplier code of conduct, supplier ESG assessment process, supply chain due diligence, incidents.

5. Company overview (5-8 facts): Legal entity details, employee count, turnover, locations, certifications (ISO 9001, ISO 14001, ISO 45001).

A complete starter vault contains 30 to 50 facts covering 80% of questions you will encounter. Use the VSME data checklist to cross-reference against the VSME framework data points.

The starter facts approach

Do not write 50 facts from a blank page. Start from what you have.

Step 1: Collect previous responses. Gather every ESG questionnaire you have completed in the past 2 years from emails, shared drives, and colleagues.

Step 2: Extract the best version of each answer. For each topic, find the strongest, most current answer — specific, evidence-backed, with numbers.

Step 3: Write as standalone facts. Rewrite each so it stands alone, not tied to a specific questionnaire's wording. Add keywords and link evidence.

Step 4: Fill gaps. Common ones include quantitative emissions data (if never measured), formal policies that exist in practice but not on paper, supply chain due diligence documentation, and specific KPIs like training hours per employee or recycling rate.

Step 5: Get the right people to review. Operations reviews environmental facts. HR reviews social. A director signs off governance. Accuracy matters — these facts will be reused across multiple customers.

Version control

Facts go stale. Three mechanisms keep your vault current:

Review dates on every fact. Quantitative data: review annually. Policies: review when updated. Company overview: review quarterly.

Version numbers. Increment when updated. Keep a log of changes — auditors and buyers may ask "When did you update this?"

Quarterly vault review. Block 60 to 90 minutes every quarter. Update figures, refresh evidence links, flag facts needing input from colleagues. This prevents the annual scramble.

How a vault changes your workflow

Without a vault: Read each question. Search old files. Rewrite from memory. Chase colleagues. Compile evidence. 3 to 5 working days.

With a vault: Match each question to existing facts by keyword. Copy and adjust. Attach linked evidence. Fill the 10-20% of unmatched questions. 2 to 4 hours.

The saving is not just time — it is consistency. When every questionnaire draws from one canonical fact, you eliminate contradictory answers that damage buyer confidence.

Use the ESG time calculator to estimate what a vault-based approach would save your business.

The minimum viable vault

Start with 15 facts covering the most frequently asked questions:

1. Company overview (name, registration, size, sector, locations)
2. Environmental policy summary
3. Carbon emissions data (Scope 1 and 2)
4. Energy consumption data
5. Waste management approach and recycling rate
6. Health and safety policy and accident rate
7. Modern slavery statement
8. Employee diversity data
9. Training and development overview
10. Anti-bribery and corruption policy
11. Whistleblowing procedure
12. Data protection / UK GDPR compliance
13. Supplier code of conduct
14. Supplier assessment process
15. Key certifications held

These 15 facts, well-written with evidence attached, answer roughly 60 to 70% of questions in a typical supplier questionnaire. Build the rest as new questionnaires reveal gaps.
