Тhe Omnibus has reduced mandatory ESG reporting obligations for most Bulgarian companies and mandatory reporting is now unlikely to apply for them
Directive (EU) 2026/470 entered into force on 18 March 2026. Bulgaria must transpose the Corporate Sustainability Reporting Directive (CSRD) by 19 March 2027 and the Corporate Sustainability Due Diligence Directive (CSDDD) by 26 July 2028.
Mandatory reporting will apply to fewer companies. Bulgaria adopted its ESG reporting framework in August 2024 through amendments to the Accounting Act. In early 2026, the National Assembly postponed the first reporting period by one year. With the Omnibus thresholds now confirmed, only a small number of Bulgarian companies are likely to remain in mandatory CSRD scope, mainly among the largest enterprises.
National implementation still matters. Bulgaria must transpose the Omnibus by March 2027. Companies that were preparing for reporting obligations under the original framework should follow the transposition process closely, as certain implementation choices remain for the national legislature.
One point should not be overlooked. ESG expectations and green-claims risk remain. For many Bulgarian companies, mandatory sustainability reporting is now less likely to apply. That does not mean ESG risk has receded. It has shifted into financing conditions, supply-chain expectations, M&A due diligence, and the legal scrutiny of public sustainability claims.
The Omnibus reduces mandatory reporting, but it does not reduce ESG-related demands from clients, banks, investors, procurement, or supply chains. Nor does it affect what companies may publicly say about their sustainability performance. Public sustainability claims are governed by a separate consumer-protection framework, which is tightening independently.
