Green Claims Directive 2026: Compliant Sustainability Claims

From September 2026, new rules apply to online shops across the EU: the Green Claims Directive prohibits vague sustainability claims such as "eco-friendly" or "climate neutral" without scientific evidence. Approximately 53% of all environmental claims in the EU are vague, misleading, or unsubstantiated according to the EU Commission (EU Commission). For e-commerce businesses, this means comprehensive action is needed: product descriptions, category texts, SEO content, and marketing claims must be systematically reviewed and updated.

What Is the Green Claims Directive?

The Green Claims Directive (GCDR) is an EU directive that must be transposed into national law by 27 March 2026 and applies from 27 September 2026. Studies show that 75% of product packaging carries at least one environmental claim (Changing Markets Foundation). It complements the already applicable Empowering Consumers Directive and establishes binding rules for all environmental claims in business communications - including online shops, marketplaces, and marketing materials.

The objective: consumers should be able to rely on environmental claims. Currently, over 230 different eco-labels and more than 100 green energy labels exist across the EU (EU Commission), many of which are neither independently verified nor scientifically substantiated. 40% of environmental claims in e-commerce are unsupported by evidence according to EU Commission studies (EU Commission). The new directive aims to end this proliferation and create a level playing field.

Which Claims Will Be Prohibited?

The directive targets generic, unsubstantiated environmental claims. For Shopware shops and other e-commerce platforms, this means: every environmental claim in product texts, category descriptions, or marketing materials must be supported by scientific evidence.

Particularly problematic are offsetting claims: claims based on carbon offsetting that suggest a product is "climate neutral" when emissions are merely compensated elsewhere are no longer permissible under the new directive. Over 40% of carbon neutrality claims rely solely on offsetting (Carbon Market Watch). Companies must demonstrate actual reduction efforts rather than buying their way out through certificate purchases.

Detailed Requirements for Sustainability Claims

The Green Claims Directive sets specific requirements for every environmental claim a business makes. For online shop operators who manage their product data professionally, this translates into clear action areas:

Impact on Shopware Product Data and SEO Content

For Shopware shop operators, the Green Claims Directive has direct implications for several areas of shop management. Product descriptions, category texts, custom fields, and SEO-optimised content must be systematically audited for non-compliant claims.

• Product descriptions: Terms like "sustainable", "eco-friendly", or "green" without source references must be removed or replaced with substantiated claims
• Category texts: Labels such as "Sustainable Products" or "Eco Collection" require justification of the criteria products meet
• Meta titles and descriptions: SEO texts with unsubstantiated environmental claims in SERPs can become legally actionable
• Custom fields and properties: Filter attributes like "Sustainable" or "Organic" must be backed by verified certificates
• Cross-selling texts: Recommendations like "Customers also bought these sustainable products" need substance
• Google Merchant Center feeds: Product attributes with sustainability references must meet the new requirements

Eco-Labels and Certifications Under the GCDR

The directive also regulates eco-labels and certification schemes. New private eco-labels are generally prohibited unless recognised at EU or national level. Existing labels must demonstrate that they are based on scientific criteria, independently verified, and transparent in their methodology.

For online shops, this means: self-created labels such as "Shop Eco Seal" or "Our Sustainability Rating" are no longer permissible. Only recognised certifications may be used as eco-labels. Businesses currently using proprietary rating systems for product sustainability must replace them with recognised certificates or mark them as company information only - without label character - by September 2026.

• EU Ecolabel - official EU environmental label
• Blue Angel - German environmental label (RAL gGmbH)
• COSMOS NATURAL / COSMOS ORGANIC - natural cosmetics standard
• FSC / PEFC - wood and paper products
• GOTS - Global Organic Textile Standard
• Cradle to Cradle - circular economy certification

Penalties and Enforcement

The EU leaves specific penalties to member states but provides a clear framework. Violations of the Green Claims Directive can result in fines of up to 4% of annual turnover. Additional consequences include temporary exclusion from public procurement, confiscation of profits from the violation, and publication of the decision - with corresponding reputational damage.

Together with the Empowering Consumers Directive, which already applies from 2026, this creates a tight net against greenwashing. Consumer protection organisations and competitors can take legal action against violations. The risk of legal challenges in e-commerce increases significantly - comparable to experiences following the introduction of GDPR or the accessibility requirements (BFSG).

Step by Step: Green Claims Compliance for Online Shops

Converting to GCDR-compliant product communication requires a structured process. Professional consulting can help realistically assess the effort and set priorities.

1. Inventory (content audit): Search all product texts, category pages, blog articles, metadata, and marketing materials for environmental claims and document them
2. Assessment and classification: Classify each identified claim as compliant, adjustable, or to be removed - considering existing certificates and evidence
3. Evidence procurement: Request missing certificates and scientific evidence from manufacturers and suppliers, or commission life cycle assessments
4. Content revision: Replace non-compliant claims with substantiated, specific formulations - referencing certificates, studies, or measurements
5. Technical implementation: Create new fields for sustainability evidence in Shopware, upload certificate PDFs, and set up links to audit reports
6. Verification: Have revised content reviewed by legal department or specialised e-commerce consultants
7. Monitoring: Establish regular review of new product texts and automated screening for prohibited terms

AI-Powered Analysis and Content Optimisation

For shops with hundreds or thousands of products, manually reviewing all texts is hardly economical. AI-powered solutions can significantly accelerate the process: automated detection of problematic formulations, suggestions for compliant alternatives, and systematic data enrichment of large product catalogues with verified sustainability information.

The European sustainability market in e-commerce is growing steadily. 73% of consumers worldwide are willing to change their purchasing behaviour to reduce environmental impact (Nielsen). The European market for sustainable products reaches €140 billion (Euromonitor International). At the same time, only 20% of consumers trust companies' sustainability claims (Kantar). The Green Claims Directive addresses precisely this trust gap - and offers companies with genuine sustainability credentials the opportunity to credibly differentiate themselves.

Connection to the Digital Product Passport

The Green Claims Directive does not stand alone: it is part of a comprehensive EU regulatory framework for sustainable products. The Digital Product Passport (DPP), which becomes mandatory for an increasing number of product categories from 2027, will serve as the central carrier of verified environmental data. Those who prepare their product data for the GCDR today simultaneously lay the groundwork for the Digital Product Passport.

The topics of greenwashing prevention and sustainable shop design also gain additional relevance through the new legislation. B2B retailers face particular challenges as they frequently adopt manufacturer claims in their product descriptions and are liable for their accuracy.

Sustainable Product Communication as Competitive Advantage

The Green Claims Directive is more than a regulatory obligation - it offers a strategic opportunity. Companies that proactively transition their sustainability communication to scientifically substantiated claims win the trust of an increasingly critical audience. 66% of consumers say they are willing to pay more for sustainable products (McKinsey/NielsenIQ). Transparency and credibility become the decisive differentiators.

Those who act now not only avoid fines and legal challenges but position themselves as trustworthy providers in a growing market segment. The investment in compliant product communication pays off through higher customer loyalty, better conversion rates among environmentally conscious buyers, and sustainable brand reputation.
