DPP and Greenwashing: How the EU Is Using Passports to Enforce Honesty

Greenwashing is not just a marketing problem — it is a market failure. When consumers cannot distinguish genuinely sustainable products from those making unsubstantiated claims, the incentive for real sustainability investment collapses. Companies that invest in genuine environmental improvements cannot capture a price premium because consumers have no way to verify their claims.

The EU Digital Product Passport is designed to solve this verification problem at the architectural level. By embedding verifiable data into every product, the DPP makes greenwashing not just difficult to hide, but structurally impossible to sustain.

The Scale of the Problem

The European Commission’s 2020 study on green claims found:

• 53.3% of examined green claims provided vague, misleading, or unfounded information
• 40% of claims had no supporting evidence whatsoever
• Half of all green labels had weak or no verification procedures

This is not a niche issue. Greenwashing affects every product category and consumer segment, eroding trust in sustainability claims across the entire market.

The Regulatory Response

The EU has developed a multi-layered regulatory framework to combat greenwashing, with the DPP playing a central technical role:

Regulatory Framework Hierarchy:

LEVEL 1: Cross-cutting Consumer Protection
├── Unfair Commercial Practices Directive (UCPD)
│   └── Prohibits misleading claims in any context
│
LEVEL 2: Green Claims Specific
├── Empowering Consumers for the Green Transition Directive (ECD)
│   └── In force March 2024, applies from 27 Sept 2026
│   └── Bans generic claims ("eco-friendly," "sustainable") without proof
│   └── Bans carbon offset claims for "climate neutrality"
│   └── Bans self-created sustainability labels
│
LEVEL 3: Product-Level Verification
└── Digital Product Passport (under ESPR)
    └── Mandatory, structured, verifiable product data
    └── Third-party verified for critical data points
    └── Machine-readable for automated enforcement

The ECD’s Key Provisions

The Empowering Consumers Directive (adopted March 2024, applicable from 27 September 2026) establishes specific prohibitions:

• Generic environmental claims — Terms like “sustainable,” “eco-friendly,” “green,” “environmentally friendly” are banned unless the specific environmental performance is demonstrated through verifiable data
• Carbon neutrality claims — Cannot claim a product is “carbon neutral” based on carbon offsetting. Must be based on actual emission reductions in the product’s value chain
• Self-created labels — Companies cannot create their own sustainability labels; labels must be based on certification schemes approved by the Commission
• Future performance promises — Stricter rules for claiming future environmental improvements

Green Claims Directive Status

The proposed Green Claims Directive (GCD), which would have required pre-market verification of all green claims, was withdrawn by the European Commission in June 2025 due to concerns about the administrative burden on micro-enterprises. However, enforcement is continuing under existing laws — the ECD, UCPD, and national-level enforcement are all active without the GCD.

How the DPP Enables Enforcement

The DPP provides the technical infrastructure to make green claims verifiable:

Enforcement in Practice: Recent Cases

Despite the GCD’s uncertain status, enforcement against greenwashing is intensifying across Europe under existing legal frameworks:

These enforcement actions demonstrate that regulators are actively policing green claims regardless of the GCD’s status. The DPP provides the structural solution: rather than relying on reactive enforcement, it embeds verification into the product itself.

The DPP Enforcement Mechanism

How DPP data can be used to verify green claims:

Consumer sees claim: "This T-shirt has a 40% lower carbon footprint"
         │
         ▼
Scans DPP QR code on garment
         │
         ▼
Accesses structured DPP data:
├── Carbon footprint: 2.4 kg CO₂e (verified, ISO 14067)
├── Industry average: 4.0 kg CO₂e (reference)
└── Verification body: TÜV Rheinland (certificate #12345)
         │
         ▼
Claim is verifiable in real-time by anyone

OR, if claim is false:

Consumer sees claim → scans DPP → data doesn't match → reports to market surveillance
         │
         ▼
Regulator investigates → finds discrepancy → penalties apply

What This Means for Brands

1. Every sustainability claim must be DPP-verifiable — Claims made in marketing, on packaging, or at point of sale must be backed by structured data in the passport
2. Avoid generic language — Terms like “eco-friendly” and “sustainable” without specific, DPP-verifiable data are increasingly risky
3. Third-party verification is essential — Self-declared claims will face the highest regulatory scrutiny
4. Carbon neutrality claims require actual data — Carbon offset-based neutrality claims will be illegal under the ECD from September 2026
5. Greenhushing is not the answer — Some brands are staying silent to avoid risk, but transparent, well-substantiated claims remain a competitive advantage

The Future of Green Claims

The trajectory is clear: green claims regulation is moving from a trust-based system to a verification-based system. The DPP provides the verification infrastructure. The ECD provides the legal mandate. And national enforcement authorities provide the penalties.

Brands that build their sustainability marketing on verified DPP data will be well-positioned for this future. Brands that continue to rely on vague, unverifiable green claims face increasing regulatory, legal, and reputational risk.

The DPP turns greenwashing from a marketing strategy into a compliance violation — and in doing so, creates a market where genuine sustainability investments are rewarded and verified.
