Greenwashing: When Brand Sustainability Claims Don't Match the Parent

A dishwashing liquid bottle says "100% plant-based actives" on the front. The back label says "other non-plant-based actives are included." A chocolate company calls itself a sustainability leader while investigations find children as young as ten using machetes on cocoa farms in its supply chain. A berry brand runs an environmentally friendly campaign while testing reveals pesticide residues including PFAS, the so-called forever chemicals.

Greenwashing is not a victimless marketing sin. Plant-based claims carry significant weight with environmentally and health-conscious consumers. When those claims are misleading, consumers pay premium prices for products that are not what they appear to be. The brands that most aggressively market their values tend to be either genuinely independent or acquired by companies that benefit from that marketing.

Here are four real cases from 2026 that show how greenwashing works, how regulators are responding, and how to spot it before you buy.

What Is Greenwashing?

Greenwashing is the practice of making misleading or false environmental claims to appear more sustainable than reality. Common tactics include:

• Vague language: "eco-friendly," "sustainable," "natural" without definition or verification
• Green imagery: leaves, earth tones, nature scenes on packaging that create an impression of environmental responsibility
• Single-attribute claims: "recyclable packaging" while ignoring the environmental impact of the product inside
• Misleading certifications: some large companies have introduced their own certifications with lower standards than independent ones
• Front-of-pack claims corrected by back-label disclaimers: a bold claim on the front, a quiet correction on the back
• Sustainability reports that highlight wins but omit failures: selective disclosure that paints an incomplete picture

Case 1: Unilever and the CMA Greenwashing Investigation

The UK Competition and Markets Authority (CMA) launched an investigation into Unilever over environmental claims on its home and personal care products. The CMA identified several specific concerns:

• Vague and broad environmental claims: Statements and language that could mislead shoppers
• Ingredient claims exaggerating how natural the product is: Claims that overstate the natural composition of products
• Claims focusing on a single aspect of a product that may suggest it is environmentally friendly as a whole
• Unclear claims in relation to recyclability: Statements about recyclability that lack specificity
• Use of colours and imagery such as green leaves, which may create the impression that some products are more environmentally friendly than they actually are

Unilever said it was "surprised and disappointed" and refuted that its claims are misleading. But the CMA's investigation is ongoing, and the regulator has made clear that it will take action if it finds greenwashing.

Unilever owns Dove, Ben & Jerry's, Seventh Generation, Hellmann's, and hundreds of other brands. The investigation covers the parent company's claims across its portfolio.

Case 2: Unilever Sunlight Platinum and the "100% Plant-Based" Ruling

In a separate case, South Africa's Advertising Regulatory Board (ARB) ordered Unilever to change the "100% plant-based active" claim on the front of its Sunlight Platinum dishwashing liquid packaging.

The case illustrates the front-of-pack, back-of-pack greenwashing tactic perfectly. The front label states "100% plant-based actives." The back label, in small print, states "other non-plant-based actives are included." A consumer complained that if other non-plant-based actives are included, the product cannot contain 100% plant-based actives.

Unilever defended the claim by explaining that the product contains rhamnolipids (branded as RhamnoClean), a surfactant produced from sugar via biological fermentation. The company said the claim is intended to highlight this specific ingredient, not the whole product.

The ARB accepted that rhamnolipids themselves are 100% plant-based. But the board found that a consumer seeing "100% plant-based active" on the front would reasonably assume that the whole product is 100% plant-based, or that the only active ingredient is plant-based. The ARB ruled that relying on a back-label disclaimer to correct a misleading front-of-pack claim is not acceptable.

The ARB stated: "Simply put, it is not permissible to make a statement that is confusing at best, and misleading at worst on the front of a product, and then clarify on the back of the product that this is not the only active ingredient."

The ARB viewed the headline claim as effectively a type of greenwashing and instructed Unilever to amend the packaging within three months.

Case 3: Mondelez and the "Sustainability Leader" vs Reality

Mondelez International has built a reputation on sustainability. Mondelez was the first company to raise the issue of deforestation in the cocoa sector at COP21 in Paris in 2015 and adopted a formal Human Rights Policy in 2021. It has high ESG ratings from major rating agencies.

But a Rainforest Action Network (RAN) investigation tells a different story. The investigation found:

• Child labor in cocoa supply chain: Children as young as ten using machetes to harvest cocoa pods on a Ghanaian farm allegedly linked to Mondelez. Approximately 1.56 million children work on cocoa farms in West Africa.
• Palm oil from illegally cleared peatlands in Sumatra, sourced from producers allegedly linked to violent campaigns against Indigenous and traditional communities.
• Leading efforts to delay the EU Deforestation Regulation, which would require companies to prove their products do not come from recently deforested land.

RAN stated: "Those actions were meant to signal sustainability leadership to the public, investors, and regulators. But the evidence points elsewhere."

The question is no longer whether Mondelez has policies, which it clearly does. The question is whether those policies serve as meaningful safeguards, or as a way to launder its reputation to the public. The Mondelez case raises a broader question about the $45 trillion ESG investing market. If a company can receive top sustainability ratings while documentary evidence links it to regulatory obstruction, deforestation, and allegations of child labor, what exactly are those ratings measuring?

Mondelez owns Oreo, Cadbury, Ritz, Toblerone, and many other brands.

Case 4: Driscoll's and the PFAS Lawsuit

Driscoll's, the largest berry brand in the US, faces a class-action lawsuit alleging greenwashing. The lawsuit claims that Driscoll's ran an environmentally friendly campaign while greenwashing its true farming and manufacturing practices, which included forever chemicals.

Testing found residue of 12 pesticides in strawberries, 8 of which are considered PFAS (per- and polyfluoroalkyl substances). The lawsuit states that Driscoll's "environmental stewardship and sustainability representations and misleading partial disclosures are material to consumers' purchasing decisions" and "contribute to the premium reputation and value associated with the Driscoll's brand."

Driscoll's has rejected the allegations and believes they are without merit.

This case is notable because it involves not just vague marketing claims but specific allegations about the presence of regulated chemicals in the product itself. PFAS are called "forever chemicals" because they do not break down in the environment or the human body. If the allegations are proven, consumers who bought Driscoll's berries specifically because of the brand's sustainability marketing paid a premium for products that may contain substances they were trying to avoid.

The Greenwashing Playbook: 6 Common Tactics

Based on these cases and others, here are the six most common greenwashing tactics:

1. Vague language. "Eco-friendly," "sustainable," "natural" without definition or third-party verification. These words have no legal definition in most jurisdictions.

2. Green imagery. Leaves, earth tones, nature scenes on packaging. The CMA specifically called out Unilever's use of "colours and imagery, such as green leaves, which may create the impression that some products are more environmentally friendly than they actually are."

3. Single-attribute focus. "Recyclable bottle" while ignoring the environmental impact of the product inside. A recyclable container does not make the contents sustainable.

4. Self-created certifications. Some large companies have introduced their own certifications. These often have lower standards than independent ones like USDA Organic, Fair Trade, or B Corp.

5. Misleading front-of-pack claims corrected by back-label disclaimers. The Sunlight Platinum case is a textbook example. The ARB ruled that this practice is not acceptable.

6. Sustainability reports that highlight wins but omit failures. Selective disclosure that paints an incomplete picture. Companies report reductions in operational emissions while omitting Scope 3 supply chain emissions, which are typically far larger.

The ESG Rating Paradox

The Mondelez case exposes a structural problem with ESG ratings. Companies can receive high scores for having policies, even when investigations show those policies are not enforced.

Mondelez has a formal Human Rights Policy, adopted in 2021. It has a Cocoa Life sustainability program. It was the first company to raise deforestation at COP21. These are all real actions that ESG rating methodologies reward.

But the RAN investigation found child labor, deforestation, and sourcing from producers linked to violence against Indigenous communities. These findings suggest that the policies exist on paper but are not adequately implemented or enforced in the supply chain.

The Mondelz case raises a broader question about the $45 trillion ESG investing market. ESG ratings can reward having policies, not implementing them. Investors and consumers who rely on ESG ratings without cross-referencing with field investigations may be getting a false picture.

How to Spot Greenwashing as a Consumer

1. Look for specific, measurable claims rather than vague adjectives. "50 percent recycled content" is specific. "Eco-friendly" is not.

2. Check if claims cover the whole product or just one attribute. A "recyclable bottle" says nothing about what is inside.

3. Verify certifications through independent directories. USDA Organic, Leaping Bunny, B Corp, and Fair Trade all have public databases where you can check current status.

4. Read the back label. Does it contradict the front? If the front says "100% plant-based" and the back says "other non-plant-based actives are included," that is a red flag.

5. Check the parent company's full portfolio and record. Use WhoBrands.com to find the parent, then search for controversies and investigations.

6. Search for NGO investigations and regulatory actions. Organizations like RAN, Greenpeace, and Ethical Consumer conduct field research that rankings miss. Regulatory bodies like the CMA and South Africa's ARB publish rulings online.

Do not rely on the label.

What This Means for Consumers

Greenwashing is pervasive. It appears on packaging, in sustainability reports, in corporate communications, and in ESG ratings. Regulatory bodies are cracking down. The CMA in the UK, the Advertising Regulatory Board in South Africa, and the SEC in the US are all taking action against misleading environmental claims.

But enforcement lags behind marketing. By the time a regulator rules against a company, consumers have already paid premium prices for products that were not what they claimed to be. The Sunlight Platinum case took months to resolve. The Mondelez investigation took years. The Driscoll's lawsuit is still pending.

Consumers must verify independently. The brands that most aggressively market their values tend to be either genuinely independent or acquired by companies that benefit from that marketing. Use the tools available: WhoBrands.com to find the parent company, bcorporation.net to verify B Corp status, ethicalconsumer.org for independent ratings, and search engines for recent controversies and lawsuits.
