Lithuania Tightens Greenwashing Rules from September 2026: Fines Up to 6% of Turnover

On September 27, 2026, amendments to the Republic of Lithuania Law on the Prohibition of Unfair Commercial Practices (Law No. XV-577) will enter into force, transposing Directive (EU) 2024/825 into national law. These amendments establish stringent new standards for public communication, advertising, and consumer product information.

Article 2 of the Law introduces statutory definitions for generic environmental claims, recognized excellent environmental performance, software updates, and replacement parts. Furthermore, Article 7 (the blacklist of commercial practices prohibited under all circumstances) is expanded to explicitly target greenwashing. Specifically, businesses will be prohibited from:

1. Making generic environmental claims (such as 'green', 'eco-friendly', 'climate-smart', or 'sustainable') without demonstrable recognized environmental performance verified through official schemes (such as the EU Ecolabel under Regulation (EC) No 66/2010 or standard LST EN ISO 14024).
2. Displaying private or self-created sustainability labels that are not based on an independent third-party certification scheme.
3. Making claims that a product has a neutral or positive greenhouse gas emissions impact when such claims are based solely on carbon offsetting.

The regulatory updates also cover product durability and technical servicing. It will be illegal to omit or conceal information regarding the availability of spare parts, repair limitations, or how software updates affect device functionality and longevity.

Under Article 13 of the Law, non-compliance carries severe administrative penalties: fines of up to 3% of the company's annual revenue in the preceding financial year (capped at €100,000), increasing up to 6% of annual revenue (capped at €200,000) for repeated violations within a 12-month period. Minor infractions may result in a formal warning.

Prior to the enforcement deadline, businesses must audit product packaging, e-commerce catalog descriptions, marketing claims, and contract terms to eliminate unsubstantiated environmental representations and ensure technical durability disclosures meet statutory criteria.
