What is Greenwashing and Why You Need to Know About It
Have you ever picked up a product from the supermarket shelf because the packaging was green, adorned with leaves, and promised to be “100% natural” or “eco-friendly”? Well, that feeling of doing the right thing for the planet can often be exactly what companies want you to feel — even when the product is not truly sustainable. This phenomenon is called greenwashing, and it is becoming increasingly sophisticated, harder to detect, and prevalent in our daily lives.
The term, which translates to “greenwashing,” describes the practice of companies — and even governments — using marketing strategies to appear environmentally responsible without actually adopting practices that justify this image. It’s a form of deception that harms not only consumers but also genuinely committed sustainable companies and, of course, the environment itself. After all, when we buy from those who engage in greenwashing, we stop supporting those who are genuinely working for concrete changes.
The good news is that learning to identify greenwashing is entirely possible, and this skill becomes a powerful tool in your hands as a consumer. In this article, we’ll understand where this practice comes from, how it works in real life, and, most importantly, what you can do to avoid falling into this trap.
The Origin of Greenwashing: Where Does This Practice Come From
The concept was coined by American environmentalist Jay Westerveld in 1986, criticizing hotel chains that asked guests to reuse towels “in the name of the environment” — while expanding their constructions in ecologically sensitive areas. Since then, the practice has evolved significantly.
With the growth of environmental awareness in recent decades, brands realized that sustainability sells. Consumer behavior studies consistently show that a growing portion of people are willing to pay more for products perceived as sustainable. This created a huge incentive for companies to adopt a green aesthetic without necessarily changing their operations.
In the current context, in 2026, with increasingly urgent climate goals established under the Paris Agreement and growing investor pressure for ESG (Environmental, Social, and Governance) reports, greenwashing has also migrated to the corporate and financial world — with investment funds and large corporations inflating their environmental credentials to attract capital.
The 7 Most Common Forms of Greenwashing
The environmental organization TerraChoice, still widely cited in sustainable marketing studies, identified recurring patterns of greenwashing that remain relevant. Here are the main ones:
- Vague or Undefined Claims: terms like “natural,” “green,” “eco,” or “sustainable” without any explanation of what this means in practice.
- Focus on a Minor Attribute: highlighting that the packaging is recycled while the production process is highly polluting.
- Lack of Proof: claims that cannot be verified by any certification or concrete data.
- Irrelevance: stating something true but irrelevant — like “CFC-free,” when CFCs have been banned by law for decades.
- Outright Lies: using fake certifications or inventing non-existent seals.
- Exaggeration: claiming the product is “100% sustainable” when this is technically impossible for any production chain.
- Blame Shifting: selling as “green” an inherently harmful product to the environment, like “organic” cigarettes or “low-carbon” fossil fuels.
Greenwashing in Brazil: Current Situation
In Brazil, the topic has gained more regulatory attention in recent years. The National Council for Advertising Self-Regulation (CONAR) has judged cases of misleading advertising with environmental appeal and has specific guidelines for ecological advertising. The Consumer Protection Code (CDC) also protects consumers against misleading advertising, which includes false environmental claims.
The Ministry of the Environment and Climate Change and IBAMA have the authority to inspect and fine companies making false environmental claims about their products. Despite this, enforcement is still considered insufficient by industry experts, given the volume of products and campaigns circulating in the national market.
In the financial sector, the Securities and Exchange Commission (CVM) has intensified its attention on funds that self-declare as “ESG” without clear criteria — a form of greenwashing that can directly harm investors seeking to allocate capital responsibly.
How to Identify Greenwashing: A Step-by-Step Guide
Now for the practical part. Following these steps before buying a product can make all the difference:
- Read Beyond the Packaging. Green packaging, leaves, and words like “natural” mean nothing on their own. Look for concrete information about ingredients, processes, and impacts.
- Look for Recognized Certifications. In Brazil and worldwide, there are reliable seals. Check if the product has certifications such as:
- FSC (Forest Stewardship Council) — for wood and paper products
- ABNT NBR ISO 14001 — environmental management
- Rainforest Alliance — for food and agricultural products
- PROCEL — energy efficiency
- Ecocert / IBD — for cosmetics and organic products
- Research the Company, Not Just the Product. A company that launches an “eco” line but has a history of deforestation, environmental liabilities, or lawsuits with IBAMA deserves extra attention. Use tools like the IBAMA portal, recent news, and NGO reports.
- Question Vague Claims. If the label says “made with natural ingredients,” ask: which ones? In what proportion? Is the rest of the formula safe?
- Check if the Claim is Relevant. “Paraben-free” may be true, but what about other preservatives? Is the product as a whole more sustainable than alternatives?
- Use Verification Apps and Tools. There are apps and platforms that help verify the origin and impacts of products, such as Buscapé Sustentável and supply chain traceability initiatives.
- Trust Independent Sources. Websites of organizations like the Akatu Institute, Greenpeace Brazil, and WWF Brazil publish evaluations and rankings of companies based on verifiable environmental criteria.
Greenwashing vs. Real Sustainability: Know the Difference
The table below helps visualize the differences between honest environmental communication and greenwashing:
| Characteristic | Real Sustainability | Greenwashing |
|---|---|---|
| Evidence | Verifiable data, audited reports | Vague claims, no source |
| Certifications | Third-party recognized seals | Self-made or non-existent seals |
| Scope | Considers entire supply chain | Highlights only one positive aspect |
| Transparency | Admits limitations and future goals | Promises perfection without caveats |
| History | Coherence between speech and actions | Contrast between image and practice |
A company genuinely committed to sustainability usually talks about goals, timelines, and limitations — because it knows that transition is a process, not a final state. Those who engage in greenwashing generally announce perfect results without showing the path.

The Role of Consumers and Companies in Change
Identifying greenwashing is important, but the ultimate goal is not to create paranoia — it’s to strengthen your power of choice. When more informed consumers make better choices, they send a clear signal to the market: true sustainability has value.
Companies that truly invest in sustainable practices — such as verified emission reductions, certified renewable energy use, responsible waste management, and transparent supply chains — deserve our support. Similarly, pressuring companies that engage in greenwashing, whether through complaints to CONAR, Procon, or simply opting for more honest competitors, helps raise the market standard.
At the corporate level, the global trend in 2026 is towards stricter regulation. The European Union, for example, has approved specific legislation against greenwashing in products marketed within the bloc, requiring companies to substantiate their environmental claims with audited data. It’s a model that Brazilian experts advocate as a reference for the country.
Conclusion: Your Power of Choice is a Real Tool
Greenwashing is a real challenge, but it is not insurmountable. With a little attention, research, and the right tools, anyone can become a more conscious and demanding consumer — and this, multiplied by millions of Brazilians, has a huge impact.
Start small: the next time you pick up a “green” product from the shelf, pause for a second and ask two questions — what’s the proof of this? and who certifies this claim? These two simple questions already put you far ahead of most consumers.
And if you want to go further on your path to conscious consumption, exploring choices like How Much Does It Cost to Install Solar Energy at Home in 2026? can show how practical and verifiable decisions make a real difference — without green smoke.
The planet needs real action. And you, well-informed, are a fundamental part of this change.
