CSRD Explained: What Industrial Companies Need to Report and When

The Corporate Sustainability Reporting Directive narrowed sharply in 2026, but the operational workload did not disappear with it. As of May 2026, an EU manufacturer generally falls under CSRD when net turnover exceeds €450 million and the average headcount passes 1,000 employees, with revised-scope reporting starting on financial year 2027 data. The hard work usually starts earlier, inside factories, procurement, logistics, and supplier conversations.

Treat the new thresholds as a scope test, not as a signal to pause data work. Many manufacturers that no longer file directly will still receive data requests from larger customers, and those requests now run into a value-chain cap for companies with 1,000 employees or fewer. The practical issue splits cleanly between legal obligation and commercial pressure from buyers further up the chain.

Before the scope rules, timelines, and supplier mechanics get into detail, the substance below points to where most industrial readiness programmes succeed or fail.

• The revised CSRD scope is much narrower than the 2022 version, yet group turnover and consolidated employee counts still need a careful test.

• The first revised-scope reporting year points to FY 2027 data, with reports due in 2028.

• ESRS reaches well beyond carbon, covering energy, pollution, resources, workers, governance, and supplier practices when material to the business.

• Supply-chain data is the weak point, especially where suppliers cannot provide product-level emissions or traceable primary data.

Which manufacturers must meet CSRD requirements?

Under the 2026 Omnibus amendment, EU manufacturers are in scope when they exceed €450 million in net turnover and an average of 1,000 employees during the financial year. Non-EU industrial groups need a separate test if they generate significant EU turnover through an EU subsidiary or branch.

The old shortcut of "large company equals CSRD" is no longer safe. The revised threshold sits well above the previous 250-employee line, and many mid-market manufacturers that were preparing under the original directive now sit outside the legal filing perimeter. That does not always mean less work, because customers still in scope will pass requirements down the chain.

One scope conclusion is not enough. Acquisitions, divestments, headcount growth, or shifts in EU revenue can move a manufacturer in or out of the perimeter from one year to the next, so finance and legal should refresh the test against the revised directive text before the annual reporting timetable locks. Subsidiaries also feel the effect indirectly when customer data requests arrive even though another entity in the group is the legal filer.

When do CSRD reports start for manufacturers?

For manufacturers that remain in scope under the revised CSRD, the key reporting year is financial year 2027, with reports expected in 2028. Companies that were previously in earlier waves need to check national implementation, because Member States can exempt certain out-of-scope companies for financial years 2025 and 2026.

A report due in 2028 is built from 2027 data. That means systems, supplier requests, emission factors, plant-level records, and evidence routines have to be running during the reporting year itself, not retrofitted afterwards. Sustainability teams that wait for the report draft to start chasing primary data usually end up filing estimates they later have to defend.

The transition period carries the trickiest nuance. Some companies that filed or prepared under the first wave fall outside the revised scope, and Member States have room to exempt those companies for FY 2025 and FY 2026. Until national transposition completes, local law still governs the immediate filing obligation, and the safest position is to confirm status country by country rather than assume the EU-level reset applies automatically.

What ESRS data must manufacturers collect?

Manufacturers start with ESRS 2 general disclosures and a double materiality assessment, then report the topical ESRS data that is material. In practice, industrial companies usually need data from climate, energy, pollution, water, materials, waste, workforce, and supplier-related processes, because those areas tie directly to factories and value chains.

CSRD data collection is not a sustainability-team exercise alone. Each function owns part of the evidence and has to deliver it in a form that can stand up to assurance. Operations holds plant energy and process records, procurement holds supplier files, logistics holds freight activity, finance holds turnover, CapEx, OpEx and controls, and HR holds workforce metrics.

• Energy and emissions (Operations): MWh by plant, Scope 1 and Scope 2 figures, material Scope 3 categories, with meter readings and invoices as evidence.

• Materials and waste (Operations and Procurement): raw material inflows, recycled content, and waste outflows tied to plant records and disposal documentation.

• Water and pollution (Operations): abstraction, discharge, and pollutant data where the site profile or regulator filings make it material.

• Workforce (HR): own-workforce metrics including headcount, turnover, health and safety, and pay gap evidence drawn from payroll systems.

• Governance and supplier conduct (Procurement and Finance): supplier payment behaviour, code-of-conduct adoption, and management oversight records.

• Taxonomy linkage (Finance): turnover, CapEx, and OpEx mapped to eligible and aligned activities, reconciled with the statutory accounts.

Climate carries particular weight in the ESRS delegated regulation: a manufacturer that concludes climate is not material has to explain that conclusion in detail. For energy-intensive sites in particular, the same data also drives commercial outcomes, which is why we wrote about the cost decisions that energy volatility forces on industrial production. Sustainability reporting and margin protection draw from the same underlying records.

Why do CSRD supply-chain gaps hurt manufacturers?

Supply-chain gaps hurt manufacturers because many material ESRS disclosures depend on data that lives outside the company's own systems. Scope 3 emissions are the clearest example, where supplier-specific information is often missing, incomplete, or still scattered across spreadsheets.

A manufacturer can control its plant meters and invoices. It cannot simply pull product carbon footprints, supplier energy mixes, recycled-content evidence, or upstream transport activity from its ERP if the suppliers themselves never collected that information. The reporting template is rarely the failure point. The interface between procurement and suppliers is.

Background: The 2025 MIT and CSCMP State of Sustainable Supply Chains study drew on 1,203 responses from 97 countries. Scope 3 typically represents more than 75% of a company's emissions, yet about 70% of respondents named lack of supplier-specific information as the biggest measurement barrier.

That gap maps directly onto decision workflows. Procurement needs to know which suppliers matter most for materiality and emissions exposure, and finance needs an evidence trail that explains estimates, gaps, and changes over time. A broad questionnaire sent once a year will not fix this, because the company still cannot prioritise high-impact suppliers or track whether data quality is improving. We have written before about how the same problem of fragmented inputs plays out in specialty chemicals procurement decisions, where five moving cost components have to be tracked together rather than separately.

How should manufacturers request supplier data under CSRD?

Manufacturers should request only the supplier data they can justify for CSRD reporting, especially when the supplier has 1,000 employees or fewer. The new value chain cap means protected suppliers can decline information that exceeds the voluntary standard boundary for CSRD purposes, as confirmed in the European Commission's explanatory note on value-chain reporting.

Reporting manufacturers can still ask for additional information, but they have to distinguish between what they can require and what the supplier has a statutory right to decline. An overbroad request creates friction without improving report quality, and that has direct consequences for procurement relationships.

1. Segment first: rank suppliers by materiality, emissions weight, and exposure before any data request goes out.

2. Ask for the minimum: scope each request to the smallest data set that supports the relevant ESRS disclosure.

3. Flag cap-exceeding asks: mark any question that goes beyond the voluntary standard boundary and document why it matters.

4. Record everything: log supplier responses, assumptions, and follow-up plans so the reporting team can show how missing information was handled.

Supplier engagement in manufacturing is already moving in this direction. Nearly 45,000 companies across 110 countries were asked to disclose environmental data through CDP Supply Chain in 2025, and manufacturing represented the largest share of top disclosing sectors.

How do manufacturers make CSRD data audit-ready?

Manufacturers make CSRD data audit-ready by documenting the source, owner, method, assumption, and approval route for each material data point. The assurance challenge is not only whether a number exists, but whether the company can show how it was produced and why it is reliable enough to report.

Auditors look for evidence that plant data, supplier data, estimates, and management judgments follow a repeatable process. A spreadsheet holds a number; it rarely proves ownership, version history, supplier response status, methodology changes, and sign-off on its own. The control work, not the tool choice, decides whether limited assurance lands cleanly.

The value-chain rule deserves a careful read. EFRAG's implementation guidance on value chain states that value-chain information is required when the material impact, risk, or opportunity sits beyond own operations and the disclosure requirement specifically calls for it. That gives manufacturers permission to focus control effort where the data actually changes the report, rather than chasing every supplier for every possible metric.

The same discipline carries over from the way industrial teams already handle external data in procurement, energy, logistics, and market-risk decisions. Traceable inputs under uncertainty are not new to operations leaders, and CSRD evidence work draws on exactly that habit of mind.

Manufacturers now need supplier evidence

Scope thresholds dominate the early CSRD debate, but manufacturers feel the regulation most through evidence flows. A company can fall outside mandatory reporting and still face customer requests, while an in-scope manufacturer can pass the threshold test and still struggle when suppliers cannot deliver usable data.

The real readiness test is whether operations, procurement, finance, and sustainability can defend one shared data trail. Supplier requests should become more targeted now that the value chain cap applies, which raises the value of materiality-based prioritisation rather than mass questionnaires. Manufacturers that already connect external signals to commercial decisions hold a stronger base for the evidence work that CSRD demands.

Treat the next quarter as a data-readiness sprint. Confirm the legal scope with finance and legal, map the ESRS data already under your control, and isolate the supplier evidence that procurement needs to start collecting before FY 2027 begins. The reporting deadline is fixed, but the time to design the data trail is the year before it.

Frequently Asked Questions (FAQ)

Does CSRD still affect a supplier with fewer than 1,000 employees?

Yes, CSRD can still affect that supplier through customer data requests, even if the supplier itself does not have to file a CSRD report. The value chain cap gives protected suppliers a right to decline CSRD-purpose requests that exceed the voluntary standard boundary, so buyers need to ask more precisely and justify what they ask for.

Do U.S. manufacturers need to report under CSRD?

Yes, a U.S. manufacturer can fall under CSRD if its EU footprint meets the third-country undertaking thresholds. The revised rules focus on significant EU turnover combined with the presence of an EU subsidiary or branch, so U.S. groups should test the EU perimeter carefully rather than assume CSRD applies only to EU-headquartered companies.

What if a manufacturer cannot obtain supplier data for CSRD?

The manufacturer should document the efforts it made, why the information could not be obtained, and how it plans to close the gap. That does not make weak data harmless, but it creates a defensible record when value-chain information is genuinely unavailable and the auditor asks how the company handled the missing input.

Does CSRD require manufacturers to report EU Taxonomy KPIs?

Yes, in-scope non-financial manufacturers also need to address EU Taxonomy reporting where applicable. The core financial KPIs are turnover, CapEx, and OpEx linked to taxonomy-eligible and taxonomy-aligned activities, which means finance has to work directly with sustainability and operations to reconcile the numbers.

Is ESRS reporting the same as a carbon footprint?

No, ESRS reporting is much broader than a carbon footprint. Climate data is central for many manufacturers, but the standards also cover material topics such as pollution, water, resource use, workforce matters, value-chain workers, business conduct, and governance practices when they pass the materiality test.

Will CSRD reports need assurance?

Yes, CSRD reporting is tied to limited assurance. The 2026 amendment postponed the EU limited assurance standards deadline to 1 July 2027, so manufacturers should already build data trails that an assurance provider can test, even before the final assurance standard is settled in detail.
