What is greenwashing and why it matters in 2026

You’re probably seeing sea of products labelled as “eco-friendly,” “natural,” “green,” or “planet positive.” Brands today are eager to showcase their sustainability credentials. However, not all environmental claims are as genuine as they appear. In recent years, sustainability has moved from being a niche concern to a mainstream expectation. Consumers increasingly want to support businesses that care for people and the planet. Consequently, companies are under growing pressure to demonstrate their environmental commitment. Unfortunately, this pressure has also given rise to a troubling practice known as greenwashing.

Greenwashing allows organizations to appear environmentally responsible without making meaningful changes to their business practices. As a result, consumers are often misled, truly sustainable businesses are disadvantaged, and global sustainability efforts suffer. So, what exactly is greenwashing, and why should sustainability advocates care?

What is greenwashing?

Greenwashing refers to the practice of making misleading, exaggerated, or false sustainability claims to create the impression that a company, product, or service is environmentally friendly when it is not. The term was coined in the 1980s by environmentalist Jay Westerveld after observing hotels encouraging guests to reuse towels under the guise of environmental conservation while making little effort to reduce their broader environmental impacts.

Today, greenwashing has become widespread across industries, including fashion, energy, food, technology, finance, and consumer goods. In simple terms, greenwashing occurs when companies invest more in marketing their sustainability efforts than in actually becoming sustainable.

Why do companies engage in greenwashing?

There are several reasons why businesses resort to misleading sustainability claims.

Growing consumer demand for sustainability: Consumers increasingly prefer brands that align with their values. Studies consistently show that many shoppers are willing to support companies with strong environmental credentials.

As sustainability becomes a competitive advantage, some organizations attempt to capitalize on the trend without implementing meaningful changes.

Pressure from investors and stakeholders: Environmental, Social, and Governance (ESG) performance has become an important consideration for investors. Consequently, companies may exaggerate their sustainability initiatives to attract investment or maintain a positive public image.

Reputation management: Businesses facing criticism over environmental impacts may use sustainability campaigns to improve their reputation rather than address underlying issues.

Lack of clear regulations: Although regulations around environmental claims are increasing globally, inconsistent standards still allow vague or unsubstantiated claims to persist.

Common greenwashing tactics

Greenwashing can take many forms. Some tactics are obvious, while others are far more subtle.

Using vague language: Words such as “green,” “eco-conscious,” “natural,” or “environmentally friendly” often sound impressive but may lack clear definitions or supporting evidence. For example, a company may describe a product as “all natural” without explaining what that actually means.

Highlighting minor environmental benefits: A business may promote a single sustainable feature while ignoring its larger environmental footprint. For instance, a clothing brand may advertise garments made from recycled packaging while continuing to rely heavily on fossil-fuel-based synthetic fabrics and overproduction.

Misleading visuals and packaging: Images of forests, leaves, waterfalls, and earthy colours can create the illusion of sustainability even when no meaningful environmental benefits exist.

Lack of transparency: Companies sometimes make broad corporate sustainability claims without providing data, measurable targets, or third-party verification.

Irrelevant claims: A product may advertise itself as being free from a harmful substance that has already been banned by law for decades. While technically true, such claims can mislead consumers into believing the product is more sustainable than alternatives.

Real-world greenwashing examples

Fast fashion

Many fast fashion brands have launched “sustainable” collections containing small percentages of recycled materials. However, critics argue that these initiatives often fail to address fundamental issues such as overproduction, waste generation, poor labour conditions, and excessive resource consumption. Promoting a limited “green” collection while continuing unsustainable business practices is frequently cited as an example of greenwashing in fashion.

Fossil fuel companies

Several major oil and gas companies have faced criticism for extensive advertising campaigns highlighting renewable energy investments while the majority of their capital expenditure remains focused on fossil fuel extraction. Such campaigns may create the impression that companies are transitioning rapidly toward sustainability when their core business models remain largely unchanged.

Single-use plastics

Some brands market plastic packaging as “recyclable” even in regions lacking adequate recycling infrastructure. Although technically recyclable, much of this packaging may ultimately end up in landfills or the environment.

Carbon neutral claims

An increasing number of organizations claim to be “carbon neutral” primarily through carbon offset purchases rather than significant emissions reductions. While offsets can play a role in climate action, experts emphasize that they should complement–not replace–direct emissions reductions.

How greenwashing impacts sustainability

Greenwashing is not merely a marketing issue. Its consequences extend far beyond individual purchasing decisions.

It undermines consumer trust: When consumers repeatedly encounter misleading sustainability claims, they may become skeptical of all environmental messaging. This erosion of trust can harm genuinely sustainable businesses that are making real efforts to reduce their impacts.

It slows genuine climate action: Greenwashing creates the illusion of progress without delivering meaningful environmental improvements. As a result, companies may delay necessary changes while continuing business as usual.

It diverts resources away from real solutions: Organizations that invest heavily in sustainability marketing rather than operational improvements may allocate resources inefficiently, limiting investments in innovation, renewable energy, circular economy initiatives, and emissions reductions.

It creates unfair competition: Businesses genuinely committed to sustainability often incur higher costs to improve supply chains, reduce emissions, or adopt responsible sourcing practices. Greenwashing enables less responsible companies to compete unfairly by benefiting from sustainability-related consumer demand without making comparable investments.

The rise of new forms of greenwashing

As sustainability conversations evolve, so do greenwashing practices. Today, experts are increasingly discussing related concepts such as:

AI washing: Exaggerating or misrepresenting artificial intelligence capabilities or sustainability benefits.
ESG washing: Overstating environmental, social, or governance performance.
Net-zero washing: Making ambitious climate pledges without credible implementation plans.
Climate washing: Portraying climate commitments more positively than warranted.

These emerging practices highlight the growing need for transparency, accountability, and evidence-based sustainability communication.

Why transparency matters

Authentic sustainability requires more than attractive marketing campaigns. Organizations committed to sustainability should:

Set measurable environmental targets: Clear targets give sustainability efforts direction and accountability. Instead of broad promises, companies should define specific goals for emissions, waste, water use, energy efficiency, or sourcing. Measurable targets make it easier to track progress over time and identify where improvements are needed. They also help stakeholders judge whether a company is making genuine change or simply using sustainability language to improve its image over the long term.

Publicly disclose progress: Transparency is essential because sustainability claims mean little without evidence. Companies should share regular updates on their environmental performance, including both achievements and areas where targets have not yet been met. Public reporting allows consumers, investors, and regulators to see whether commitments are credible. It also encourages internal accountability, since teams are more likely to follow through when progress is visible and measurable across the entire organization.

Report both successes and challenges: Honest sustainability communication should not focus only on positive outcomes. Sharing setbacks, delays, and unresolved issues shows that a company is taking its responsibilities seriously and understands the complexity of real environmental change. This kind of openness builds trust because it signals that the organization is not hiding problems behind polished marketing. It also creates space for improvement, learning, and more realistic long-term planning.

Seek independent verification where possible: Third-party verification strengthens sustainability claims by showing that they have been reviewed by an external expert or certification body. Independent checks reduce the risk of exaggerated reporting and give audiences more confidence in the information being shared. Whether through audits, certifications, or verified disclosures, outside validation helps separate genuine progress from marketing spin and makes environmental claims more credible to stakeholders and the public overall.

Prioritize real impact over brand image: The most credible sustainability strategies are those that change how a business operates, not just how it is perceived. Real impact comes from reducing emissions, improving supply chains, cutting waste, and investing in long-term solutions. When companies focus on substance rather than appearance, they are more likely to create meaningful environmental benefits and less likely to fall into greenwashing over the long term.

Transparency allows stakeholders to distinguish meaningful action from misleading sustainability claims.

At last

Greenwashing poses a significant challenge to global sustainability efforts. While sustainability marketing can help raise awareness and encourage positive action, it becomes problematic when claims are exaggerated, misleading, or unsupported. As consumers, citizens, and sustainability advocates, we must move beyond slogans and look for evidence, transparency, and accountability.

Because ultimately, genuine sustainability is not about appearing green. It is about creating measurable, lasting, and positive change for people and the planet.
