The Growing Problem of Greenwashing in Modern Commerce

Greenwashing has become one of the most pervasive problems in modern commerce, eroding consumer trust and undermining genuine sustainability efforts. Studies consistently show that a significant proportion of environmental claims made by businesses are misleading, exaggerated, or entirely unsubstantiated. From vague labels such as "eco-friendly" and "natural" to cherry-picked statistics that obscure a product's true environmental impact, greenwashing takes many forms and causes real harm to consumers, competitors, and the planet.

The European Commission's own research found that over half of environmental claims examined across the EU were vague, misleading, or unfounded. This prompted the Empowering Consumers for the Green Transition Directive (EU) 2024/825, which applies from 27 September 2026 and bans generic environmental claims that cannot be substantiated; a further Green Claims Directive that would have added pre-verification was proposed in 2023 but never adopted, the Commission signalling its withdrawal in June 2025. Digital Product Passports sit at the heart of this enforcement framework, providing a standardised mechanism for verifying sustainability claims at the product level.

The financial incentive to greenwash is substantial. Products marketed as sustainable often command premium prices, and businesses face enormous pressure to demonstrate environmental credentials. Without a rigorous verification system, the temptation to overstate or fabricate claims remains strong. DPPs change this equation fundamentally by creating a transparent, auditable record of every environmental attribute associated with a product.

How Digital Product Passports Create Verifiable Evidence

At their core, Digital Product Passports function as structured data repositories that link specific environmental claims to measurable, verifiable evidence. Rather than allowing manufacturers to make broad statements about sustainability, DPPs require granular data points that can be independently audited and cross-referenced.

The verification framework within DPPs operates across several dimensions:

• Material composition data must be declared with precise percentages, preventing vague claims about recycled content or natural materials.
• Carbon footprint figures must be calculated using standardised methodologies such as ISO 14067 or the Product Environmental Footprint (PEF) framework.
• Supply chain documentation must trace materials back to their origin, substantiating claims about ethical sourcing or conflict-free minerals.
• End-of-life information must detail actual recyclability rates rather than theoretical possibilities.
• Durability metrics must be supported by testing data, preventing inflated claims about product longevity.

This evidence-based approach transforms sustainability claims from marketing assertions into auditable statements of fact. When a manufacturer claims that a product contains 70% recycled content, the DPP must contain the supporting documentation, supplier certificates, material analysis reports, and batch-level traceability data, that validates this claim.

The EU Regulatory Framework Against Greenwashing

The European Union has constructed an increasingly comprehensive regulatory framework to combat greenwashing, with the Ecodesign for Sustainable Products Regulation (ESPR) serving as a central pillar. The ESPR mandates that product-level environmental information be accessible through Digital Product Passports, creating a standardised infrastructure for claim verification.

The Empowering Consumers Directive complements the ESPR by establishing specific rules about how environmental claims may be made. Under it, generic claims such as "eco-friendly" or "green" are banned unless excellent environmental performance can be demonstrated, claims based on offsetting cannot be used to say a product is climate neutral, and sustainability labels are only allowed when based on a certification scheme or established by public authorities. DPPs provide the data backbone that makes this verification practical at scale.

Together, these regulations create a three-layered defence against greenwashing. The ESPR mandates what data must be collected and disclosed. The Empowering Consumers Directive governs how that data can be used in marketing. And the DPP infrastructure provides the technical mechanism for storing, sharing, and auditing the underlying evidence. This integrated approach makes it significantly harder for companies to make unfounded claims without detection.

Standardised Metrics That Eliminate Ambiguity

One of the most effective ways DPPs prevent greenwashing is by replacing subjective language with standardised metrics. Terms like "sustainable," "green," and "eco-friendly" are inherently ambiguous, they mean different things to different people and can be applied to virtually any product regardless of its actual environmental performance. DPPs eliminate this ambiguity by requiring specific, quantifiable data.

For carbon footprint claims, DPPs mandate the use of recognised calculation methodologies that account for the full product lifecycle. This prevents companies from cherry-picking favourable lifecycle stages whilst ignoring significant emission sources. A manufacturer cannot claim a product is "low carbon" without declaring the actual carbon footprint figure, the methodology used, the system boundaries considered, and the data sources employed.

Similarly, claims about recyclability must be grounded in practical reality rather than theoretical possibility. A DPP requires information about which materials can actually be recycled using existing infrastructure, what proportion of the product is recyclable by weight, and whether disassembly is required before recycling. This level of specificity makes it impossible to label a product as "recyclable" when only a small fraction of its materials can realistically be recovered.

Durability claims must likewise be supported by standardised testing data. Rather than vaguely promising that a product is "built to last," manufacturers must declare specific metrics such as expected lifespan under normal use conditions, the number of cycles tested for components subject to wear, and the availability of replacement parts.

Supply Chain Transparency as a Greenwashing Countermeasure

Many greenwashing claims relate to supply chain practices, ethical sourcing, fair trade, deforestation-free, and similar assertions that are difficult for consumers to verify independently. DPPs address this challenge by requiring supply chain transparency that extends beyond the finished product to encompass raw materials and intermediate processes.

When a company claims its products are made from sustainably sourced materials, the DPP must contain traceability data that links this claim to specific suppliers, certifications, and audit reports. This creates an unbroken chain of evidence from raw material extraction through to the finished product, making it far more difficult to make unsubstantiated claims about supply chain practices.

The transparency requirements also extend to subcontractors and lower-tier suppliers, addressing the common practice of outsourcing environmentally harmful processes to less visible parts of the supply chain. By requiring comprehensive supply chain mapping, DPPs ensure that sustainability claims account for the full production ecosystem rather than only the final assembly stage.

Consumer Empowerment Through Data Access

DPPs empower consumers to become active participants in greenwashing detection by providing direct access to the environmental data underlying product claims. Rather than relying solely on marketing materials, consumers can scan a product's DPP to access detailed sustainability information and compare it against the claims being made.

This consumer access creates a powerful market-based enforcement mechanism. When environmental claims are publicly verifiable, the reputational risk of greenwashing increases dramatically. Consumer advocacy groups, journalists, and competitors can all access DPP data to scrutinise claims, creating a networked verification ecosystem that operates continuously rather than only during periodic regulatory audits.

The structured nature of DPP data also enables comparison tools and rating platforms that can aggregate environmental performance data across products and brands. This makes it possible for consumers to identify genuine sustainability leaders and distinguish them from companies making superficial or misleading claims. Over time, this transparency creates competitive pressure that rewards authentic sustainability efforts.

Implementing Anti-Greenwashing Measures in Your DPP

Businesses preparing to implement Digital Product Passports should view anti-greenwashing compliance not as a burden but as an opportunity to build genuine trust with consumers. The process begins with an honest audit of existing sustainability claims, identifying which are supported by robust evidence and which require strengthening.

Key implementation steps include:

• Catalogue all environmental claims currently made about your products, including on packaging, marketing materials, and websites.
• Map each claim to specific, measurable data points that can be included in the DPP.
• Establish standardised calculation methodologies for environmental metrics, ensuring consistency across your product portfolio.
• Implement supply chain documentation processes that generate the traceability data needed to substantiate sourcing claims.
• Create internal review processes that verify sustainability claims against DPP data before publication.

Using a platform like MyProductPassport simplifies this process by providing structured templates for environmental data collection and built-in validation rules that flag potential inconsistencies between claims and underlying data. This systematic approach reduces the risk of inadvertent greenwashing whilst building a robust evidence base for genuine sustainability achievements.

The Future of Honest Sustainability Communication

As DPP requirements expand across more product categories and the enforcement infrastructure matures, the landscape for sustainability communication will shift fundamentally. Companies that have invested in genuine environmental improvements will be well-positioned to benefit, as their claims will be substantiated by verifiable data. Those that have relied on vague or misleading messaging will face increasing pressure to either improve their practices or adjust their communications.

The integration of DPP data with sustainability reporting frameworks will create additional accountability mechanisms, linking product-level claims to corporate-level disclosures. This vertical integration of sustainability data makes it increasingly difficult to maintain inconsistencies between product marketing and corporate reporting.

Ultimately, the anti-greenwashing function of DPPs represents a fundamental shift towards evidence-based sustainability communication. By replacing subjective claims with standardised, verifiable data, DPPs create the conditions for a marketplace where genuine environmental performance is recognised and rewarded. For businesses willing to invest in authentic sustainability, this transparency represents a significant competitive advantage.
