ESG questionnaire response, explained.

What an ESG questionnaire asks of a drug company, in plain words

One questionnaire, from a forwarded file to a submission

1. A file arrivesA key account director forwards 18 questions from a group purchasing organization, in its own spreadsheet, due November 12.
2. Each question is matched to a topic18 questions turn out to touch 18 topics in seven sections. Wording differs from every earlier form.
3. Answers are found and checkedApproved wording is reused where it is still current. Each figure is compared with the latest inventory, and each claim with the latest evidence.
4. Owners fill the gaps and approveTwo questions nobody has answered before go to the EHS director. A carbon-neutral question goes to counsel.
5. The file goes back, and the record staysAnswers return in the requester's own format. If a figure later changes, whoever already holds it gets a correction.

Steps 2 to 4 are the subject of this guide. The people, companies and figures in this example are fictional.

Why a right answer goes stale, and three more surprises in ESG questionnaires

Four terms this guide relies on: Scope, restatement, assurance, library

The full list of 14 terms is in the summary and glossary.

Six kinds of requester behind a supplier sustainability questionnaire

In shortRating providers, a climate disclosure platform, customers, tenders, sector programs and investors all ask. They differ in what they do with the answer, and that sets how much care each one needs. A rating firm publishes a score. A hospital group may use the answer to choose a supplier. Customer demand is the part growing fastest.

The words overlap, so it helps to separate them. A rating provider turns data into a score it publishes or sells. A disclosure platform collects a standard response each year and scores it. A supplier assessment is a rating a customer asks you to take. A supplier sustainability questionnaire is a customer's own form, sometimes inside a tender, a formal contest for a contract. A sector program is an industry group's shared audit or published ranking. An investor survey feeds a fund manager's own view.

The names are examples of the kind of body, as described on their own pages on November 3, 2026. Nothing here says how any company has scored with any of them.

Companies are also getting choosier. ERM reports that most now engage with three to five ratings, and that engagement with more than ten has fallen by more than half since 2023.3 Yet 84% plan to keep engaging, and 77% want rating methods aligned more closely with reporting standards.3 A company can drop a rating. It can rarely drop a customer's form: a key account director who wants the contract fills it in.

Pharma companies also ask each other. In July 2023 the leaders of seven global biopharmaceutical companies, members of a health systems task force, wrote to suppliers setting joint minimum climate and sustainability targets.12 In November 2025 chief procurement officers from the task force's members updated those targets, adding product carbon footprints or life cycle assessments for a supplier's top 10 products by 2028.13 A contract manufacturer or an ingredient maker can sit on both sides, answering its customers and sending forms to its own suppliers.

Why 85 questionnaire questions can come down to 27 answers

In shortSustainability questionnaires overlap heavily, but rarely word for word. In the fictional case in this guide, six open forms hold 85 questions drawn from 27 topics. Climate appears in every form. The skill lies in seeing which question is being asked, then giving one answer to all of them.

Take the case this guide follows. Northwind Bio has six forms open. Their question counts run from 7 to 24, 85 in all, yet every one maps to one of 27 topics in seven sections. If each topic has one approved answer, the work of answering 85 questions shrinks to keeping 27 answers current, plus adapting each to the format and length a form asks for.

One emissions topic, as five requesters word it

The hospital wording is from the fictional sample. The others are written for this guide to show the pattern.

Format matters as much as words. A question may allow 1,000 characters, a yes or no plus a certificate, or a number per product. Numbering follows the requester's scheme: A.1 in one file, 2.1 in another, DP-02 in a rater's portal. Requesters generally expect their own structure back, so a good answer library holds meaning and evidence, and each form gets its own numbering and length on the way out.

The 2026 rules behind ESG data requests, and where each one stands

In shortNo law says "answer this questionnaire." But several laws change who asks, what they may demand and what you may claim. Europe narrowed its reporting law sharply in 2026 and gave smaller suppliers a right to decline some requests. California's first emissions report is due November 10, 2026. The US federal climate rule never took effect and is being withdrawn.

The right arrives through national law, due by March 19, 2027. A company of 1,000 or fewer employees should still know it exists, and a reporting company sending you a long form must say what goes beyond the voluntary standard.

Why hospitals and the NHS now score medicine suppliers on carbon

In shortMedicines make up a large share of a health system's own footprint, so a buyer with a climate goal has to ask its suppliers. England's National Health Service (NHS) has set the clearest path: a net zero and social value weighting since 2022, a carbon reduction plan for contracts, global emissions reporting from April 2027, and product footprints planned from April 2028 with the method still open.

Health systems are responsible for 4 to 5% of global net emissions, or 2.4 gigatonnes of carbon dioxide equivalent, according to the 2022 release of the industry's own task force.29 The NHS has published a detailed breakdown. Its net zero report, first issued in 2020 and republished as statutory guidance in 2022, says medicines account for 25% of emissions within the NHS. Anesthetic gases are 2% and inhalers 3%, and the remaining 20% lies mainly in manufacturing and freight.30

What the NHS Net Zero Supplier Roadmap asks of a medicine supplier, and when

The April 2028 line needs the closest reading. The roadmap says the NHS "will work with suppliers and regulators to determine the scope and methodology" of product footprints.4 A test version of an NHS England market survey, from June 2026, asks suppliers of medicines, medical technology and digital products about collecting product-level emissions,31 and a law firm expects a market engagement exercise on the 2028 requirement.16 So a claim that the method is settled is premature.

Yet a questionnaire may already ask for a footprint per product, and the pharma task force's 2025 targets already ask for one on a supplier's top 10 products by 2028.13 A company holding only company-level figures has to say so plainly, then plan the calculation.

Outside England the picture is patchier. We found no public survey of how many US hospital groups or purchasing organizations put sustainability questions in supplier contracts, so we give no figure. Ask your own account teams how many they received last year. That count will tell you more than any market estimate.

How one company's 2025 emissions can truthfully read three ways, and which one to give

In shortScope 2 can be counted two ways, and a figure can be preliminary or assured. Add a plant sale, which forces the base year to be recalculated, and one company has several defensible-looking numbers for one year. A questionnaire answer has to name the method and the status, and it has to be the same everywhere.

Follow the fictional Northwind Bio's 2025 numbers. Scope 1, what it burns itself, is 21,480 tonnes of carbon dioxide equivalent (tCO2e). Scope 2, its purchased energy, depends on the method. Market-based counts the electricity contracts the company bought, and gives 37,440. Location-based uses the average mix of the local grid, and gives 49,800.

What a plant sale does to a base year

A base year is the year a company measures its progress against. The GHG Protocol treats a sale as a structural change: it moves emissions to another company's books without any change in the atmosphere. So "base year emissions shall be retroactively recalculated" when the change would otherwise compromise consistency, and the company sets and discloses the significance threshold that triggers this.2 The standard names no number for significant, though it notes that one program used 10% of base year emissions.2

That is why a restatement touches more than one cell. Northwind Bio's sale changed its 2021 base to 89,270 tCO2e and its 2024 figure to 64,930. Every form that reports a trend or a percentage since 2021 is affected, along with any target stated against that base.

The questions to ask of any emissions answer before it goes

Can you still answer "carbon neutral" on a questionnaire? Which greenwashing rule reaches it

In shortA claim of being carbon neutral through offsets has become risky almost everywhere, but the rule depends on the audience. The EU's new ban covers products marketed to consumers. A form going to a hospital is business to business, where US guides and general misleading-advertising law apply. In every case the claim has to be true today, and a two-year-old answer may no longer be.

Greenwashing means making something look better for the environment than the evidence supports. Carbon neutrality is the classic case, because the phrase can mean two very different things: the emissions were avoided, or they were paid for elsewhere through offsets, credits for reductions made outside the company.

Germany's Federal Court of Justice addressed that ambiguity on June 27, 2024 (I ZR 98/23). A confectionery maker's advertisement in a food-trade newspaper said it produced "climate neutral". The court held this misleading unless the advertisement itself explained which meaning applied, because reduction and compensation are not equivalent. A link or QR code elsewhere was not enough.32 The readers were the trade, which puts the case close to a supplier's position, though it rests on German unfair competition law.

How an honest carbon-neutral answer reads after the offsets end

In the fictional case, the form asks "Are your operations or products carbon neutral? If yes, provide the certification." The 2024 answer said yes. The company stopped buying credits on January 1, 2026, and its transition plan says it does not use the phrase. A sound answer is short and specific: no, what the company does instead, what the reduction is, and where each statement comes from.

Beyond carbon: the human rights, wastewater and supplier evidence drug makers get asked for

In shortMany answers rest on documents, and documents age quietly. A policy past its review date can sit attached to three forms with nobody noticing. Drug makers face subject-specific questions too: wastewater (effluent) from sites that make active ingredients, supply chain audits, packaging and access to medicines. Each has a rule or program behind it, with its own date.

A questionnaire asking you to "attach the current version" of a policy is asking two things: that the policy exists, and that it is current. In the fictional case, a human rights policy approved in September 2023 says it is reviewed at least every three years. So its review fell due in September 2026, and three open questionnaires cite it. No figure is wrong, and the answer is still stale.

How an ESG rating data review works, and how EU law lets you check the dataset

In shortRating firms gather data on your company whether you answer or not, then often let you check it. Since July 2, 2026, EU rules say a rated company should be able to see the data used and flag factual errors. That covers facts and gives no say over the method or the score. A data review is also the place an old figure most easily survives.

A data review looks easy: the rater shows what it holds and asks you to confirm it. It takes less work than a full questionnaire, so it gets less attention. In the fictional case, the rater still holds 61,400 tCO2e, and confirming by habit would keep that number alive in a product investors read.

Regulation (EU) 2024/3005 now gives this a legal footing in the EU. Recital 12, part of the law's explanatory preamble, says rated companies should be able to verify the data used and highlight factual errors, and to get the dataset on request, as "a pure fact-checking tool". They should "under no circumstances be able to influence in any manner the rating methodologies or rating outcome".15

Article 19 requires a complaints process, covering "the sources of data used for an individual ESG rating, factual errors and mistakes".15 Recital 42 notes ratings are also used "in the procurement and supply chain context".15 Private ratings not meant for publication or distribution fall outside the regulation.15

One disclosure cycle: the CDP dates a company planned around in 2026

A cycle like this also shows why status matters. A response submitted in September fixes a figure for months. Your restatement in the following June then sits beside last year's public data, and customers may ask why the numbers differ. A short note explaining the recalculation, kept with your evidence, will answer most of them.

The eight mistakes that show up in sustainability questionnaire answers, and why each happens

In shortNo regulator or study publishes an error rate for questionnaire answers. What follows comes from the rules and the mechanics of the work. Most errors have one cause: a copied answer that lost its date, its method or its source along the way. The hardest to fix are the ones already in someone else's hands.

What makes a wrong number hard to take back

A figure in a customer's file can be copied into that customer's own Scope 3 calculation. A figure in a rater's database can be sold on. A correction needs someone to find everyone who holds the old value, explain the change without alarm, and leave a record of having done so. When there is no list of recipients, the usual result is no correction at all.

What ESG questionnaire fatigue costs in published numbers, and what nobody has measured

In shortThe one public measure we found is eight years old: 18 workdays a response and more than ten requests a year, from April 2018, or about 180 workdays. Recent surveys describe who rates and why, with no measure of hours. We found no credible public figure for the market for this software or the cost of a wrong answer. Measure your own.

How far to trust each number, and what to measure instead

Can AI answer an ESG questionnaire? What it checks well, and where a person has to decide

In shortAI suits the parts you can check: reading a form, matching a question to a topic, reusing approved text and comparing figures. It cannot decide whether a claim is fair, or fill a true gap. No drug-regulatory AI rule was written for this work, so ordinary care applies: a source for each statement, a named approver, and nothing sent unapproved.

A warning from a neighboring field: researchers tested legal research tools built to answer from retrieved documents, and found them hallucinating 17% to 33% of the time, meaning an answer that was incorrect or cited a source that did not support it. Those tools were tested in 2024 and work on law, so the rate does not transfer. The lesson does: a source attached to an answer can still fail to support it.44 Someone, or something, has to check that the passage says what the sentence says.

How ESG reporting teams answer questionnaires today: roles, hand-offs and where the 2018 survey's 18 workdays go

In shortAn ESG reporting lead coordinates from spreadsheets. EHS, procurement, compliance, HR, legal and account teams each hold a piece. By our estimate, most of the time goes to finding old answers and chasing colleagues for the same figures. Teams use spreadsheets, request-for-proposal (RFP) answer tools, ESG reporting suites or consultants, and each leaves the same gap: nothing links an answer to the evidence as that evidence changes.

Spreadsheets, answer tools, reporting suites, consultants: four ways teams run the season

From a new purchasing-group file to a correction note: Northwind Bio on October 7

In shortThis is the example from the top of the page, inside the product. Priya Ranvelle, the ESG reporting lead, sees 27 topics against six questionnaires on one matrix, fills a new 18-question file from the library, puts the assured emissions figure into every open form, and sends a drafted correction to the customer who holds the old one.

1

Every topic in every open questionnaire, on one screen

Priya's home screen is a coverage matrix: 27 topics down, six open questionnaires across. A cell can be approved, drafted and waiting for review, flagged, with its owner, or a gap. A second column shows how fresh the library's answer is, and how many questionnaires ask it.

Scope 1 and 2 emissions is amber in two columns. The Fernlake ESG Ratings data review and the Thornbeck Hospitals questionnaire both carry 61,400 tCO2e. The panel on the right shows the library answer: 58,920 tCO2e, with three numbered sources.

2

One click fills 15 of the 18 answers

The Meridian Group Purchasing file arrived yesterday from Sam Patel, the key account director. Priya clicks "Fill from the library." Twelve approved answers are reused and three more are drafted from cited passages, so 15 of 18, or 83%, are answered. Those numbers come from the sample. The solution's design target for a new file is 80% or more.

The other three go to people: the carbon-neutral question to Grace Liu, the claims counsel, and two questions the library has never answered to Omar Haddad, the EHS director.

3

A new question goes to an owner, with no invented answer

The form asks for a product carbon footprint for each product supplied. The library holds company-level emissions only, so the cell says so and routes the question to Omar. Once he writes and approves an answer, the next form that asks it fills by itself.

4

Update everywhere: the assured figure replaces the old one

Priya owns Climate and energy, so she alone is offered the update. The library says 58,920 tCO2e for 2025: Scope 1 of 21,480 and market-based Scope 2 of 37,440, with limited assurance from Corrigan Vale Assurance LLP, restated in June 2026 after the sale of a plant. One click writes it into the Fernlake and Thornbeck answers, and both now read "Updated from the library today." The change goes on the audit trail with every questionnaire it touched.

5

The customer who already has the old number gets a note

Merrow Health received 61,400 in March. A submitted answer is never changed silently, so a correction note is drafted from the facts register, the list of current approved figures: the plant sale, the recalculation, the assured figure and page 22 of the report. Sam Patel sends it, as the account lead.

The claim check, the facts register, the owners view and the dashboard, on screen

In shortBehind the matrix sit one workspace per questionnaire, a library of documents and a register of current figures, an owners view, an export with its approval log, and a dashboard. Each screen below shows one control that a spreadsheet lacks.

Six agents read and check each sustainability answer; section owners approve it

In shortSix agents read each form, match each question, draft with citations, check figures and claims, route work and write the file back. They never approve anything. Each section owner approves their answers, counsel gives a second approval on public environmental claims, the ESG reporting lead signs off, and only approved answers export.

Questionnaire controls that make every answer defensible

From rating portals and customer spreadsheets to a cited file with its approval log

In shortIn go the questionnaires and everything your answers already rest on. Out comes a coverage matrix, cited drafts in each requester's own format, assigned gaps, correction notes and a submission file with its approval log. It connects to the systems your sustainability data already lives in, across your whole portfolio of sites and requesters.

It connects to the kinds of system you already run: your document management system or policy library, EHS data system, HR data, email and identity provider. Answers go back as files in the requester's own format, or as a portal export.

To be measured on your own forms: about half the time per questionnaire (the 2018 survey's 18 workdays to about 9, our estimate, which is about 90 workdays a year at 10 requests) and a design target of 80% or more of a new file filled from the library on arrival. The sample shows 83% and 31 catches. None of these is a measured customer result.

What a questionnaire season and a wrong answer cost you, and how to find your own number in a week

In shortThe one published figure, from a 2018 survey, works out to about 180 workdays a year. A wrong figure has no published price. It may mean a correction to a customer, a data dispute with a rater, or a lost tender weighting. You can measure the part that matters most in a week, from your last five forms.

Your return on automating ESG questionnaire responses: days back, fewer corrections

In shortThe return you can count comes from workdays per form and fewer wrong answers. The rest, such as tender weightings and rating movement, is real and much harder to attribute. The calculator counts the first two. Replace each illustrative input with your own. Any return that rests on a number you cannot measure in a pilot is a guess.

In shortEight questions, scored 0 to 2, and one for reflection. A low score points to foundations to fix first, and fixing them pays back with or without software. Your answers stay on this page.

Questions to ask any ESG questionnaire software vendor about citations, restatements and claims

In shortAsk these of anyone selling this kind of tool, including us. Good answers come with a demonstration on one of your own past forms. A vendor who answers with an auto-fill percentage on its own sample has yet to test your work.

An 8-week pilot on your past ESG questionnaires, with results you can score

In shortPilot on three to five past forms whose answers you can check, including one with a known restatement. Add one live form if the first results hold. Keep your owners approving, and decide on numbers you set before you began.
