Greenwashing: What It Is and How to Spot It in Practice

Imagine walking into a store and picking up a product with green packaging, printed leaves, and a promise of being “100% sustainable.” You feel good, pay a little extra, and leave convinced you made the right choice for the planet. But what if that feeling was just an illusion carefully crafted by marketing?

This is greenwashing — a practice that grows alongside consumer environmental awareness. As more people seek sustainable choices, more companies find incentive to appear green without necessarily acting green. The result is a market full of noise, where distinguishing genuine commitment from ecological window dressing becomes increasingly difficult.

The good news is that identifying greenwashing is a skill that can be learned. With a few right questions and a critical eye, any consumer can filter what’s genuine from what’s just communication strategy. In this article, you’ll understand what greenwashing is, why it’s harmful, and most importantly, how to recognize it in everyday life.

What is greenwashing and why does it exist

The term greenwashing was coined by American environmentalist Jay Westerveld in 1986, criticizing hotel chains that asked guests to reuse towels under the guise of saving the environment, but without any other concrete environmental practices.

Decades later, the concept has evolved and become more sophisticated. Today, greenwashing can appear in advertising campaigns, product labels, corporate sustainability reports, and even in companies’ political positions. The logic behind it is simple: environmental concern has become a market asset. Consumer behavior research worldwide consistently shows that a growing share of people are willing to pay more for products perceived as sustainable. This creates a powerful incentive for companies to communicate an environmental commitment that often doesn’t actually exist.

The central problem isn’t just ethical — it’s also practical. When consumers are deceived, they continue financing production models that cause real environmental harm, believing they’re doing the opposite.

Why greenwashing is harmful beyond individual deception

The impact of greenwashing goes far beyond a misinformed consumer. It distorts the entire sustainable products market, making it harder for companies that seriously invest in environmental practices to compete on equal footing. If a company spends real resources on responsible supply chains, emissions reduction, and proper waste disposal, but competes with another that merely repositions its communication, the incentive for real change diminishes.

There’s also an effect on public trust. When greenwashing scandals come to light — and they do, with increasing frequency — many consumers begin to distrust all environmental claims, including legitimate ones. This widespread skepticism can paralyze exactly the type of conscious demand we need to drive systemic transformations.

Finally, greenwashing delays public policies. When large companies manage to position themselves as sustainable without being so, they reduce political pressure for stricter regulations. The European Union has advanced on this front — in 2024 it approved the Green Claims Directive, which requires environmental claims to be verified by independent third parties before reaching consumers. In Brazil, the discussion is still at an early stage within the National Council for Advertising Self-Regulation (CONAR) and legislative projects under consideration.

The seven most common forms of greenwashing

The Canadian organization TerraChoice (now incorporated into UL) identified, in influential studies on environmental labeling, recurring patterns of misleading claims. Although the market has changed, these patterns remain current:

• Vague or undefined claim: terms like “eco-friendly,” “green,” “natural,” or “sustainable” without any specification of what this means or how it was measured.
• No proof: a company claims to reduce emissions but presents no data, audited reports, or verifiable certifications.
• Irrelevance: highlighting a true environmental attribute that doesn’t matter in the product’s context. Example: “CFC-free” on products that never used CFCs, since the substance has been banned for decades.
• Outright lie: false statements, such as claiming certification that doesn’t exist.
• Lesser of two evils: an inherently problematic product presents itself as the “greener” option in its category — organic cigarettes are the classic example.
• Fake certification: logos that imitate recognized seals but were created by the company itself.
• Selective emphasis: communicating only positive aspects and hiding negative ones. A company may advertise that its packaging is recyclable while omitting that its production process is highly polluting.

How to identify greenwashing in practice: a step-by-step guide

Step-by-step to evaluate an environmental claim

1. Read beyond the label. Ignore the green color and decorative leaves. Look for the concrete claim: what exactly is being promised?

1. Ask: is it specific? “Made with 30% post-consumer recycled material” is specific. “Eco-friendly” is not. Vague claims are an immediate red flag.

1. Verify the certification source. Seals like FSC (Forest Stewardship Council), Rainforest Alliance, ISO 14001, and Energy Star have independent audit processes and public criteria. Research whether the displayed seal actually exists and whether the company is on the list of certified entities.

1. Look for sustainability reports. Companies with real commitment usually publish annual reports based on recognized frameworks, such as GRI (Global Reporting Initiative) or TCFD. The complete absence of these documents, especially in large companies, is suspicious.

1. Contextualize the claim. A fossil fuel company that launches a “clean energy” line representing less than 1% of its portfolio hasn’t changed its business model — it has merely diversified its communication.

1. Seek independent news. Environmental journalists, NGOs like the Environmental Defense Fund or Greenpeace, and fact-checking platforms may have investigated the company. A quick search with the brand name and “greenwashing” can reveal a lot.

1. Use available tools. In the US, the FTC’s Green Guides provide standards for environmental marketing claims. Globally, the CDP (formerly Carbon Disclosure Project) database allows you to consult climate disclosures from public companies.

Greenwashing in context: what’s happening in 2026

Environmental accountability occupies a peculiar position in today’s discussion. Countries with significant biodiversity and critical ecosystems face special scrutiny, both from international investors and increasingly informed domestic consumers.

In recent years, cases of questionable “carbon offsetting” have gained attention. Some companies announced carbon neutrality by purchasing credits from reforestation or forest protection projects that, in subsequent investigations, presented serious problems with additionality (meaning the forest would probably be preserved anyway) or permanence (the trees were cut down years later). The voluntary carbon market still lacks robust standardization, although regulatory frameworks like the EU’s Carbon Border Adjustment Mechanism (CBAM) represent important steps in this direction.

Advertising regulatory bodies have received numerous complaints related to misleading environmental advertising in recent years, and some relevant decisions have been made, recommending the suspension of campaigns. Still, self-regulation has limits, and the expectation is that specific legislation will advance.

Companies with real commitment: how they differentiate themselves

Not everything is greenwashing — and it’s important to recognize this to avoid falling into paralyzing skepticism. Companies with genuine environmental commitment usually present distinct characteristics:

• Goals with deadlines and verifiable metrics, aligned with scientific frameworks like the Science Based Targets initiative (SBTi).
• Transparency about difficulties and failures, not just achievements.
• Engagement throughout the entire value chain, not just in final products.
• Political lobbying consistent with their message, meaning they don’t fund groups that fight environmental regulations while presenting themselves as green.
• Certifications from independent third parties with public criteria and periodic audits.

If you want to reduce plastic at home with simple steps, for example, part of that process involves choosing brands that truly invest in alternative packaging — and knowing how to distinguish who really does this is exactly what this article aims to help you do.

The consumer’s role: small actions with real impact

Recognizing greenwashing isn’t just an intellectual exercise — it’s an act with real consequences. When consumers start demanding evidence before buying, companies find themselves obligated to go beyond communication and invest in concrete changes.

Some practical actions you can adopt today:

• Question before buying: if the claim isn’t specific and verifiable, treat it as marketing, not fact.
• Prefer known certifications: research seals before trusting them.
• Share information: when you identify a clear case of greenwashing, share it with your network. Social pressure and public scrutiny are powerful tools.
• Value transparent companies: support brands that publish data, admit limitations, and present concrete plans.
• Report when necessary: the FTC accepts complaints about misleading advertising through ftc.gov. Consumer protection agencies in your region can also be contacted in cases of deceptive advertising with consumer impact.

Conclusion: your attention is a tool for transformation

Greenwashing exists because it works — or at least it worked for a long time. But as consumers, journalists, regulators, and investors become more sophisticated, the cost of being caught in a false narrative increases. Companies that bet on transparency and real impact are increasingly well-positioned, both ethically and commercially.

You don’t need to be a sustainability expert to make more informed choices. Just develop the habit of asking the right questions: what exactly is being promised? Who verifies this? What is the real impact, not just the perceived one?

Every conscious purchase, every complaint to regulatory agencies, every conversation about the subject is a step toward a more honest market. And a more honest market is a prerequisite for environmental solutions that actually work. Start today — the planet thanks you.
