Greenwashing Explained: How Environmental Claims Can Mislead

Greenwashing does not require a company to invent an environmental achievement from nothing. Some of the most difficult cases begin with something that is technically true.

A package may contain less plastic than its previous version. A factory may use renewable electricity. A company may purchase carbon credits, publish a net-zero target or receive certification for one environmental attribute. Each statement can contain legitimate information while the overall communication creates a much broader impression than the evidence supports.

That gap between what has actually been demonstrated and what an ordinary audience is likely to conclude is where greenwashing becomes important.

The United Nations describes greenwashing as communication that makes an organisation appear to be doing more for the environment than it actually is. Its examples include vague terms such as green or eco-friendly, exaggerating a minor improvement, highlighting one favourable environmental attribute while ignoring larger impacts and announcing net-zero ambitions without credible plans for achieving them. (un.org)

The problem is therefore wider than outright lying.

Environmental claims can mislead through scope, omission, imagery, comparison, accounting choices and emphasis. A statement can be literally correct and still encourage an interpretation that is difficult to justify.

Credible environmental communication does the opposite. It tells the audience what improved, how much, compared with what, over which part of the product or organisation, during which period and according to which evidence.

Greenwashing thrives when those boundaries disappear.

The Overall Impression Matters More Than One Technically True Sentence

Consider a company that reduces the plastic weight of one bottle by 10%.

“Bottle contains 10% less plastic than our 2025 bottle” is a specific comparative claim. A buyer can understand what changed and which baseline is being used.

Now imagine the same company places the bottle inside green packaging covered with forests and labels the product “a sustainable choice for the planet.”

The factual reduction has not changed.

The implied claim has.

The marketing may now suggest that the product has a broad environmental advantage even though the company has demonstrated only one relatively narrow packaging improvement. Total material consumption might even increase if sales rise substantially.

This distinction is recognised in environmental-marketing regulation. The U.S. Federal Trade Commission's Green Guides caution businesses against broad, unqualified claims such as green or eco-friendly because such language can imply numerous environmental benefits that are extremely difficult to substantiate. The FTC recommends qualifying general claims with clear, specific environmental attributes and warns that even a genuine improvement can be misleading if advertising implies an overall environmental advantage that has not been established. (ftc.gov)

This produces one of the most useful tests for analysing greenwashing:

What would a reasonable reader think this claim means?

That question is often more revealing than asking only whether every individual word can be defended.

Advertising works through context.

Text interacts with photography, colour, packaging, charts, certification marks and the information that has been left out. A technically accurate sentence can acquire a much broader implied meaning because of everything surrounding it.

Greenwashing therefore often occurs in the distance between literal wording and communicated impression.

Vagueness Makes Environmental Claims Difficult to Test

Words such as green, sustainable, clean, natural, responsible, eco-conscious and environmentally friendly sound positive while often saying very little about environmental performance.

Sustainable in what respect?

Lower greenhouse-gas emissions?

Less packaging?

Lower water use?

Reduced toxicity?

Better forestry practices?

Longer product life?

Greater recyclability?

The word alone does not tell us.

This ambiguity is useful to marketers because a broad positive impression can be created without committing to a measurable proposition.

Compare two claims:

“Eco-friendly packaging.”

and

“Packaging weight reduced by 24% compared with our 2024 design.”

The second claim could still be false or misleading, but at least it creates something that can be tested. The product, percentage and baseline are visible.

The FTC's guidance follows this logic. It advises marketers to make environmental qualifications clear, prominent and specific and warns against implying that small or insignificant improvements amount to major overall environmental benefits. (ftc.gov)

Specificity does not automatically make a claim credible.

It makes credibility easier to evaluate.

A meaningful environmental statement normally answers some combination of five questions:

What changed? How much? Compared with what? Over what boundary? During what period?

Greenwashing becomes easier when those questions remain unanswered.

This is why environmental communication increasingly requires more than an attractive adjective.

The noun and number behind the adjective matter.

Selective Disclosure Can Turn a Small Improvement Into a Large Impression

Organisations create many different environmental impacts.

A manufacturer may produce greenhouse-gas emissions, use water, generate hazardous waste, depend on mined materials and affect biodiversity through its supply chain. A clothing company may have impacts from fibre production, dyeing, transport, unsold inventory, packaging and garment disposal.

Environmental performance therefore has multiple dimensions.

A company can genuinely improve one while worsening another.

This creates an opportunity for selective disclosure.

Imagine a fashion brand that replaces conventional shopping bags with recycled-paper bags and promotes the change heavily. The improvement may be real. But if packaging represents only a very small portion of the product's environmental footprint, using that achievement to position the entire business as sustainable may create a disproportionate impression.

The UN lists this explicitly among common greenwashing tactics: emphasising one environmental attribute while ignoring other environmental impacts or promoting the sustainability of a product in isolation from the environmental performance of the organisation producing it. (un.org)

Materiality matters.

Not every advertisement can contain a complete lifecycle assessment.

Nor should companies be prohibited from describing smaller improvements.

The issue is proportionality.

A claim about one narrow attribute should normally remain a claim about that attribute rather than being transformed into evidence that the entire product or company is environmentally sustainable.

The same principle applies to compliance.

A company may advertise that a product does not contain a harmful substance even though the substance is already prohibited or was never commonly used in that product category.

The statement can be technically true while providing almost no meaningful environmental information.

Minimum regulatory compliance should not be presented as though it were exceptional voluntary environmental leadership.

The reader needs context.

Without it, an irrelevant achievement can sound substantial.

Visual Design Can Imply Environmental Benefits Without Saying Them

Greenwashing is not confined to written claims.

A package covered in forests, leaves, water droplets and wildlife can communicate environmental meaning before a buyer reads a single sentence.

Green colour itself proves nothing.

Neither does a photograph of a mountain.

But images become relevant when they reinforce a broader environmental implication unsupported by evidence.

Imagine a disposable product marketed inside packaging resembling untreated paper, covered with leaves and accompanied by a small claim that one component contains recycled material.

A consumer may interpret the entire presentation as suggesting that the product is broadly natural, low-impact or sustainable.

The actual substantiated claim may be far narrower.

Environmental communication therefore has to be judged as communication, not as an exercise in isolating individual words.

FTC guidance similarly recognises that environmental messages may arise from the context of advertising, not just its explicit sentences, and that marketers are responsible for claims consumers can reasonably infer. (ftc.gov)

This is why disclaimers do not always rescue exaggerated advertising.

A large headline saying “Planet Positive” followed by tiny text explaining that only the shipping envelope contains recycled material may still create an overall message much broader than the qualification.

Effective disclosure has to be sufficiently clear and prominent to change how the main claim is understood.

Environmental evidence cannot live permanently in the footnotes while environmental imagery dominates the message.

Carbon-Neutral and Net-Zero Claims Need Clear Boundaries

Climate claims create especially complicated greenwashing risks because greenhouse-gas accounting involves organisational boundaries, value chains, time periods, emissions scopes, avoided emissions, removals and carbon credits.

Take the phrase carbon neutral.

It does not necessarily mean that producing the product released no greenhouse gases.

The company may have estimated a defined set of emissions and purchased carbon credits intended to compensate for an equivalent quantity elsewhere.

Whether the resulting communication is credible depends on what the claim actually covers.

Does the calculation include only the company's direct fuel use?

Purchased electricity?

Raw materials?

Transportation?

Product use?

End-of-life disposal?

If a product contains substantial value-chain emissions but a carbon-neutral claim covers only a narrow operational boundary, consumers may infer much more than the accounting demonstrates.

Offsets introduce another layer.

The FTC's existing Green Guides state that marketers making carbon-offset claims should possess competent and reliable scientific evidence and use accounting methods that prevent the same reduction from being sold more than once. (ftc.gov)

The United Nations' Integrity Matters framework goes further for corporate net-zero commitments. Its recommendations say that high-integrity voluntary credits can play a role in mitigation beyond a company's value chain, but they should not be counted as substitutes for the organisation's own interim emissions reductions. The framework calls for short-, medium- and long-term targets, public transition plans, value-chain coverage, annual progress reporting and independent verification. (un.org)

The distinction between reducing emissions and compensating for emissions therefore matters.

If a company emits one million tonnes of carbon dioxide and purchases credits representing one million tonnes elsewhere, the accounting claim may indicate compensation under a particular framework.

It does not mean one million tonnes of physical emissions disappeared from the company's operations.

Clear climate communication should explain that difference.

A Net-Zero Target Is Only as Credible as the Path Toward It

Long-term climate commitments are necessary because industrial facilities, buildings, energy systems and supply chains cannot all be transformed immediately.

The problem is that distant targets are also cheap to announce.

A company can promise net zero in 2050 while making few decisions today that would make the target achievable.

That credibility problem led the UN Secretary-General to establish the High-Level Expert Group on the Net-Zero Emissions Commitments of Non-State Entities in 2022. Its Integrity Matters report set out ten recommendations for companies, financial institutions, cities and regions making net-zero commitments. (un.org)

The recommendations make the difference between a target and a transition plan particularly clear.

A credible pledge should include interim emissions-reduction milestones, transparent reporting and a plan describing how operations, investment and the value chain will change. The framework also calls for alignment between climate commitments and lobbying or policy advocacy, because a company cannot plausibly claim leadership while supporting policies that undermine its stated transition. (un.org)

This integrity agenda moved further into implementation in 2026.

The UNFCCC secretariat formally began the pilot phase of its Net-zero Recognition Framework in February 2026. The voluntary framework is testing how net-zero initiatives and their participating organisations can disclose criteria and demonstrate alignment with the ten Integrity Matters recommendations through the UN's Non-State Actor Zone for Climate Action platform. The pilot is running through 2026, with initial findings expected to be presented at COP31. (unfccc.int)

The importance of this development is not that the UN is granting a simple global “green company” label.

It reflects a broader change in climate accountability.

A net-zero promise increasingly needs evidence about the route, milestones, accounting boundary and progress, not merely an attractive destination several decades away.

The useful question is no longer only:

Does the organisation have a net-zero target?

It is:

What has changed because of that target already?

Numbers Can Greenwash as Effectively as Adjectives

Quantification feels objective.

A percentage, chart or emissions figure can make environmental advertising appear more scientific than words such as green or natural.

Numbers, however, depend on definitions.

Suppose a company announces a 40% reduction in emissions intensity.

That could represent meaningful improvement.

But intensity is a ratio.

If the metric is emissions per unit of revenue, the company's emissions per dollar may decline while total greenhouse-gas emissions continue increasing as the business expands.

Neither number is automatically wrong.

They answer different questions.

The greenwashing risk appears when an intensity reduction is communicated in a way that leads audiences to believe total emissions have also fallen.

Baseline selection creates another possibility.

“Emissions reduced by 50%” means little without knowing the starting year. A company could choose an unusually high-emission baseline, divest a polluting business rather than decarbonise it, or exclude major parts of its supply chain.

Again, each accounting choice may have a legitimate explanation.

The requirement is transparency.

Environmental figures need denominators, boundaries, baselines and definitions.

A percentage without its denominator can conceal as much as it reveals.

The same principle applies outside climate reporting.

“90% recyclable” might refer to product weight rather than whether local recycling systems actually accept the components.

“50% less water” may refer to one manufacturing stage rather than total lifecycle water consumption.

“Zero waste to landfill” can describe waste-management destination while saying nothing about the quantity of waste created.

A number becomes meaningful only when the reader understands exactly what has been measured.

Certification Can Improve Trust—but Only Within Its Actual Scope

Environmental certification can help solve an information problem.

Consumers cannot personally inspect a forestry operation, trace every raw material or audit a company's carbon inventory before purchasing a product.

Credible standards can establish common criteria and provide independent verification.

But the presence of a badge does not automatically establish that an entire product is sustainable.

Some certifications examine only one attribute.

A forestry label may address the origin of wood or paper.

An energy label may address electricity or efficiency.

A recycled-content certification may verify material composition.

The product can still have environmental impacts outside the certification boundary.

The FTC therefore warns that seals and certifications can themselves create broad environmental claims if consumers do not understand what the certification actually represents. Its guidance recommends clearly communicating the basis for a certification rather than allowing a seal to imply unspecified overall environmental superiority. (ftc.gov)

Self-created labels require even more caution.

A company can design its own green icon that visually resembles third-party certification without any independent organisation applying a standard.

The useful questions are straightforward:

Who created the standard?

What does it evaluate?

Is certification independent?

How is compliance tested?

Is the methodology public?

How often is performance reassessed?

What important environmental impacts are outside the scope?

A credible certification can be valuable evidence.

It should reduce the need for blind trust rather than become another symbol requiring blind trust.

Greenhushing Is Not a Good Alternative to Greenwashing

Increased scrutiny creates another communication problem.

Some organisations may become reluctant to publicise genuine environmental improvements because they fear criticism, litigation or accusations that their claims are incomplete. This tendency is often described as greenhushing.

Silence avoids exaggerated claims.

It also reduces information available to investors, customers, employees and policymakers trying to distinguish environmental leaders from laggards.

The solution to greenwashing is therefore not to make environmental communication impossible.

It is to improve its quality.

A company does not need to claim that a product is “good for the planet” if it can demonstrate that the product uses 30% less virgin material than its previous design.

It does not need to call an entire business carbon neutral if it can report that renewable electricity now supplies 80% of its owned facilities.

It does not need to imply that a certification proves total sustainability when it can explain exactly what the certification verifies.

Narrower claims can actually be more useful because they allow comparison.

Environmental communication should become more specific as accountability increases, not disappear.

Credible organisations should be able to describe both progress and remaining limitations.

“Emissions fell 15%, but supply-chain emissions remain our largest unresolved source” provides more decision-useful information than either “we are saving the planet” or complete silence.

Transparency includes unfinished work.

Greenwashing Creates Market and Policy Costs Beyond One Misled Consumer

It is tempting to view greenwashing mainly as a consumer-protection problem.

A buyer thinks one detergent, airline ticket or investment fund is greener than another and makes a decision using misleading information.

That matters.

But the economic consequences extend further.

Consider two companies competing in the same market.

One invests heavily in cleaner equipment, supply-chain measurement and lower-impact materials.

The other invests mainly in environmental branding.

If consumers cannot distinguish between genuine performance and marketing, the second company can receive many of the reputational benefits without paying the cost of real environmental improvement.

Greenwashing can therefore reward communication over performance.

That weakens incentives for companies that genuinely spend money reducing environmental impacts.

Capital markets face a similar problem.

Investors increasingly use environmental information when assessing risk, strategy and portfolio alignment. If corporate claims exaggerate transition progress or hide important emissions exposures, capital can be allocated using distorted information.

Public trust is another casualty.

When prominent environmental claims are repeatedly exposed as misleading, scepticism can spread beyond the offending organisation to legitimate sustainability initiatives.

That produces a paradox: greenwashing does not merely make weak environmental action look stronger. It can make real environmental action harder to trust.

The United Nations describes greenwashing as an obstacle to climate action because misleading sustainability claims can create false confidence and delay concrete changes. (un.org)

A promise can become politically useful even when implementation remains weak.

That is why scrutiny of environmental communication is not simply linguistic policing.

The quality of claims can influence competition, investment and public policy.

Intent Is Less Important Than Evidence and Likely Interpretation

The term greenwashing can imply deliberate deception.

Sometimes deception is clearly intentional.

But analysing motive is not always necessary.

Environmental accounting is complex. Standards change. Data can be incomplete. A marketing team may exaggerate the significance of genuine work without consciously deciding to deceive anyone.

The claim can still mislead.

Consumer-protection principles often focus on the message received by the audience rather than requiring proof that the advertiser privately intended deception. FTC guidance similarly emphasises how reasonable consumers are likely to interpret environmental claims and whether those interpretations can be substantiated. (ftc.gov)

This provides a better editorial test.

Instead of asking:

“Was the company trying to greenwash?”

begin with:

“What does the evidence support, and what impression does the communication create?”

Intent may matter in enforcement, ethics and reputation.

It is not necessary for identifying an evidentiary gap.

This prevents the discussion from becoming a psychological argument about corporate motives.

A company can make a misleading environmental claim through carelessness, weak methodology or misunderstanding.

The corrective action remains similar: narrow the claim, improve the evidence, clarify the boundary and disclose material limitations.

The Best Defence Against Greenwashing Is Comparability

Greenwashing becomes easier when every organisation chooses its own terminology and metrics.

One company reports operational emissions.

Another reports emissions intensity.

A third announces “avoided emissions”.

A fourth calls itself carbon neutral after purchasing credits.

All four claims may be accompanied by green branding, but direct comparison becomes extremely difficult.

Standardisation reduces this information problem.

Common greenhouse-gas accounting frameworks, product standards, disclosure requirements, independent assurance and comparable sector-specific metrics make it harder to hide poor performance behind unique definitions.

This explains why environmental policy is increasingly moving beyond voluntary storytelling toward structured disclosure and clearer rules for claims.

The UN's Integrity Matters recommendations call for annual disclosure of greenhouse-gas data, net-zero plans and progress, alongside independent verification of reported emissions reductions. (un.org)

The UNFCCC's 2026 Net-zero Recognition Framework pilot similarly asks participating initiatives to disclose their criteria and explain their degree of alignment with each of the ten UN expert-group recommendations. (unfccc.int)

Comparable disclosure does not eliminate disagreement.

Companies can still face genuinely different circumstances.

Methodologies can still contain uncertainty.

Environmental impacts such as biodiversity are harder to reduce to one globally comparable number than greenhouse-gas emissions.

But standardisation changes the conversation.

Instead of asking whether a company sounds sustainable, users can increasingly ask whether its claims are measured in the same way as its competitors and reported consistently over time.

That is a much harder environment in which to greenwash.

Read the Noun, Number and Boundary Behind the Adjective

The easiest way to become more sceptical about environmental marketing is not to assume every green claim is dishonest.

It is to ask better questions.

When a product says sustainable, ask what aspect is being described.

When packaging says eco-friendly, ask which measurable characteristic supports the claim.

When a company says emissions fell by 30%, ask whether the figure refers to absolute emissions or intensity and which parts of the value chain are included.

When an investment is marketed as green, ask what qualifies an asset for inclusion.

When a product is called carbon neutral, ask what emissions boundary was measured and how much of the claim depends on carbon credits.

When a company promises net zero, ask about interim targets, capital investment, value-chain emissions and the transition plan already being implemented.

These questions reveal the recurring structure of credible environmental communication:

a specific subject, a measurable attribute, a clear boundary, an appropriate comparison and evidence capable of supporting the impression created.

Greenwashing works when those elements are separated.

A broad adjective floats above a narrow improvement.

A percentage appears without a denominator.

A distant target replaces current action.

A certification logo implies more than the certification evaluates.

A forest photograph provides an environmental identity that operational evidence has not earned.

The answer is not to prohibit companies from discussing sustainability.

Environmental improvement should be communicated because consumers, investors and citizens need information about who is changing and how quickly.

The standard should instead be proportionality.

The environmental impression created by a claim should be no broader than the evidence supporting it.

That principle is simple enough for a consumer label and demanding enough for a corporate net-zero strategy.

It also captures what makes greenwashing difficult.

A claim does not have to be completely false to mislead.

Sometimes all that is required is for a small truth to be made to look much larger than it really is.
