Questions & Answers on CSRD, ESRS, EU Taxonomy and ESG Disclosure
1. What is ESG reporting in the European Union?
ESG reporting in the European Union refers to mandatory and voluntary disclosure of information relating to environmental, social and governance matters.
The EU framework is designed to provide investors, regulators and other stakeholders with information about sustainability risks, opportunities and the impact of companies on people and the environment.
2. Is ESG reporting mandatory in the EU?
Yes, for companies falling within the scope of applicable EU sustainability-reporting legislation.
The most important framework is the Corporate Sustainability Reporting Directive (CSRD), supported by the European Sustainability Reporting Standards (ESRS).
However, following the 2026 Omnibus I changes, the number of companies subject to mandatory CSRD reporting has been significantly reduced.
3. What is the CSRD?
CSRD stands for Corporate Sustainability Reporting Directive.
It establishes requirements for qualifying companies to report sustainability-related information as part of their corporate reporting framework.
4. What is the main objective of the CSRD?
The CSRD aims to improve the availability, quality, comparability and reliability of sustainability information.
It helps investors and other stakeholders understand both:
- How sustainability matters affect a company; and
- How the company’s activities affect people and the environment.
5. What are ESRS?
ESRS stands for European Sustainability Reporting Standards.
Companies within the applicable CSRD scope use ESRS as the framework for preparing their sustainability statements.
6. Who develops the ESRS?
EFRAG provides technical advice for the development of ESRS, while the European Commission adopts the standards through delegated acts.
7. How many ESRS standards are there?
The ESRS framework covers cross-cutting requirements and topical standards addressing environmental, social and governance matters.
The framework includes areas such as:
- Climate change
- Pollution
- Water and marine resources
- Biodiversity
- Resource use and circular economy
- Own workforce
- Workers in the value chain
- Affected communities
- Consumers and end-users
- Business conduct
8. What is the current scope of the CSRD after the 2026 changes?
Under the 2026 Omnibus I amendments, the CSRD scope has been narrowed to companies meeting both of the key thresholds:
- More than 1,000 employees, and
- More than €450 million net annual turnover.
This substantially reduces the number of companies subject to mandatory CSRD reporting compared with the original CSRD framework.
9. Why was the CSRD scope reduced?
The EU adopted the changes to reduce administrative and reporting burdens, improve competitiveness and concentrate mandatory sustainability reporting on the largest companies.
10. What happened to companies that were originally expected to report under CSRD but are now outside the scope?
The 2026 amendments provide transition arrangements, including an exemption for certain companies that would otherwise have been in the first reporting wave but fall outside the revised scope.
11. What is the “Stop-the-Clock” Directive?
The Stop-the-Clock Directive postponed the application of CSRD reporting requirements for companies that had been scheduled to begin reporting for financial years 2025 or 2026.
It was part of the EU’s effort to provide additional time for companies while the substantive CSRD changes were being negotiated.
12. What are the revised ESRS?
The European Commission adopted revised ESRS in July 2026.
The revised standards simplify the reporting framework, reduce the number of mandatory datapoints and provide additional flexibility for companies.
13. How much has ESG reporting been simplified?
The revised ESRS reduce the number of mandatory datapoints by more than 60% and total datapoints by more than 70%, according to the European Commission.
The Commission expects the changes to reduce reporting costs by more than 30% per company.
14. What is double materiality?
Double materiality is one of the distinctive features of the EU sustainability-reporting framework.
It considers two perspectives:
Financial materiality: How sustainability matters affect the company.
Impact materiality: How the company’s activities affect people and the environment.
15. What is a double-materiality assessment?
It is a structured process through which a company identifies sustainability matters that are material from either or both perspectives.
The assessment helps determine which sustainability information needs to be disclosed.
16. Is double materiality still relevant under the revised ESRS?
Yes. The revised framework retains the materiality-based approach while simplifying the process and reducing unnecessary reporting requirements.
17. What environmental matters are covered by ESRS?
Environmental reporting can include:
- Climate change
- Pollution
- Water and marine resources
- Biodiversity and ecosystems
- Resource use
- Circular economy
- Greenhouse-gas emissions
- Energy
18. What social matters are covered?
Social reporting can cover:
- Employees
- Workers in the value chain
- Affected communities
- Consumers and end-users
- Human rights
- Health and safety
- Working conditions
- Diversity and inclusion
19. What governance matters are covered?
Governance disclosures can include:
- Business conduct
- Corporate culture
- Anti-corruption
- Anti-bribery
- Whistleblower protection
- Political influence
- Supplier relationships
- Payment practices
20. What is the EU Taxonomy?
The EU Taxonomy is a classification system designed to identify economic activities that can be considered environmentally sustainable under defined technical criteria.
21. Is the EU Taxonomy the same as CSRD?
No.
CSRD is primarily a corporate sustainability-reporting framework, while the EU Taxonomy provides a classification system for environmentally sustainable economic activities.
The two frameworks interact because companies subject to relevant requirements may need to provide Taxonomy-related information alongside sustainability disclosures.
22. What is Taxonomy alignment?
Taxonomy alignment measures the extent to which a company’s economic activities meet the EU Taxonomy’s criteria for environmental sustainability.
23. What is Taxonomy eligibility?
Taxonomy eligibility indicates whether an economic activity is covered by the EU Taxonomy classification system.
Eligibility does not automatically mean that the activity is environmentally sustainable or Taxonomy-aligned.
24. What is the relationship between CSRD and the EU Taxonomy?
CSRD provides a broader sustainability-reporting framework, while Taxonomy disclosures provide specific information about environmentally sustainable economic activities.
25. What are Scope 1 emissions?
Scope 1 emissions are direct greenhouse-gas emissions from sources owned or controlled by the company.
26. What are Scope 2 emissions?
Scope 2 emissions generally arise from purchased or acquired electricity, steam, heating or cooling.
27. What are Scope 3 emissions?
Scope 3 emissions are other indirect greenhouse-gas emissions occurring throughout a company’s value chain.
They can include emissions from suppliers, transportation, business travel, product use and other upstream and downstream activities.
28. Is Scope 3 reporting required under EU ESG rules?
The precise disclosure requirements depend on the applicable ESRS provisions and the company’s circumstances.
The revised ESRS provide additional flexibility and phase-ins for certain information, so companies should assess the specific requirements applicable to their reporting period.
29. What is the EU’s approach to climate reporting?
Climate reporting focuses on climate-related risks, opportunities, transition plans, greenhouse-gas emissions, energy and climate targets.
30. What is a climate transition plan?
A transition plan explains how a company intends to align its business strategy, investments and operations with a transition toward a lower-carbon economy.
31. What is climate-risk reporting?
Climate-risk reporting addresses both:
Physical risks – such as floods, droughts, heatwaves and extreme weather.
Transition risks – such as regulation, carbon pricing, technology changes and changing market demand.
32. What is ESG assurance in the EU?
ESG assurance is an independent examination of sustainability information intended to increase confidence in the reliability of reported information.
33. Is sustainability assurance mandatory?
Companies subject to CSRD sustainability reporting are subject to assurance requirements under the applicable EU framework.
The 2026 changes retain the requirement at the limited-assurance level rather than moving to a future reasonable-assurance requirement.
34. What is the difference between limited and reasonable assurance?
Limited assurance provides a lower level of assurance and generally involves less extensive procedures.
Reasonable assurance involves more extensive testing and provides a higher level of assurance.
The EU’s 2026 reforms maintain limited assurance for CSRD reporting.
35. Do SMEs have to follow the same ESG reporting requirements as large companies?
No.
The revised EU framework significantly reduces the mandatory CSRD scope.
The EU has also developed a voluntary sustainability reporting standard for smaller companies, designed to provide a proportionate reporting framework and protect smaller value-chain companies from excessive information requests.
36. What is the voluntary SME sustainability reporting standard?
It is a proportionate framework intended for companies outside the mandatory CSRD scope.
It can help smaller businesses respond to sustainability-information requests from banks, customers and larger companies.
37. What is the value-chain cap?
The value-chain cap is designed to prevent companies subject to CSRD from imposing excessive sustainability-data requests on smaller companies in their value chains.
The EU’s voluntary standard provides a reference point for information that smaller businesses may reasonably be expected to provide.
38. Can a small EU company voluntarily report ESG information?
Yes.
Companies outside the mandatory CSRD scope may voluntarily provide sustainability information using appropriate frameworks, including the EU’s voluntary standard for smaller companies.
39. Does ESG reporting apply to non-EU companies?
Certain non-EU companies can fall within the EU sustainability-reporting framework when they have significant business activity in the EU and meet the applicable conditions.
The 2026 amendments have also revised the thresholds applicable to third-country undertakings.
40. Can an Indian company be affected by EU ESG rules?
Yes.
An Indian company with significant operations or turnover in the EU, or a qualifying EU subsidiary or branch, may potentially fall within applicable EU sustainability-reporting requirements.
Indian companies can also face indirect ESG-data requirements when they supply large EU companies.
41. How does EU ESG reporting affect exporters?
EU customers may request information relating to:
- Carbon emissions
- Energy consumption
- Labour practices
- Human rights
- Supply-chain risks
- Environmental impacts
- Governance
- Sustainability targets
Therefore, even companies outside the mandatory CSRD scope can face ESG information requests through commercial relationships.
42. What is the role of EFRAG?
EFRAG provides technical advice and supports the development of European sustainability reporting standards.
It plays an important role in developing ESRS for the European Commission.
43. What is the role of the European Commission?
The European Commission develops and adopts EU sustainability legislation and delegated acts, including the ESRS framework.
It also coordinates the EU’s broader sustainable-finance and corporate-reporting agenda.
44. What is the role of ESMA?
The European Securities and Markets Authority (ESMA) contributes to the supervision and enforcement framework for sustainability reporting in EU capital markets.
It also follows and contributes to the development of ESRS.
45. What role do national regulators play?
EU Member States implement and supervise EU legislation through their national authorities.
Therefore, companies need to consider both EU-level requirements and the national implementation framework applicable in the country where they operate.
46. How does EU ESG reporting affect CFOs?
CFOs increasingly need to integrate sustainability information into:
- Financial planning
- Risk management
- Capital allocation
- Internal controls
- Investor communication
- Budgeting
- Strategic planning
- Corporate reporting
47. What role can accountants play in EU ESG reporting?
Accountants can contribute to:
- ESG data collection
- Sustainability reporting
- Internal controls
- Assurance
- Carbon accounting
- Materiality assessments
- Risk management
- Financial impact analysis
48. What role can management accountants play?
Management accountants can connect sustainability performance with financial decision-making through:
- Environmental cost accounting
- Carbon costing
- ESG budgeting
- Investment appraisal
- Sustainability KPIs
- Scenario analysis
- Performance measurement
- Cost optimisation
49. What is greenwashing?
Greenwashing occurs when a company or financial product makes sustainability claims that are misleading, exaggerated or insufficiently supported.
The EU has been strengthening its broader framework against misleading environmental claims and greenwashing.
50. What is the future of mandatory ESG reporting in the EU?
The EU is moving toward a more focused and proportionate ESG reporting system.
The 2026 reforms concentrate mandatory CSRD reporting on the largest companies, simplify ESRS, retain limited assurance and reduce reporting burdens while maintaining sustainability transparency for investors and stakeholders.
Conclusion
The EU remains one of the world’s most important jurisdictions for mandatory sustainability reporting, but its ESG framework has undergone significant reform.
The CSRD remains the central corporate sustainability-reporting legislation, while ESRS provide the reporting standards. The EU Taxonomy complements the framework by classifying environmentally sustainable economic activities.
The major development in 2026 is the Omnibus I simplification. Mandatory CSRD reporting has been narrowed to companies with more than 1,000 employees and more than €450 million in net annual turnover, while the revised ESRS significantly reduce the reporting burden.
For Indian and other non-EU businesses, the EU framework remains highly relevant because ESG requirements can extend through EU subsidiaries, significant EU operations and international supply chains.
For finance professionals, EU ESG reporting is becoming an important area covering sustainability accounting, carbon measurement, internal controls, assurance, risk management, materiality assessment and strategic financial decision-making.
