Introduction
Environmental awareness has become a major factor in consumer behavior. Consumers increasingly prefer products and services that are described as sustainable, eco-friendly, recyclable, carbon-neutral, natural, organic, biodegradable, climate-friendly or environmentally responsible. As a result, businesses in many sectors use environmental claims in their advertisements to differentiate themselves from competitors and appeal to environmentally conscious consumers.
However, environmental advertising is also one of the riskiest areas of modern advertising law. When a business presents a product, service or brand as more environmentally beneficial than it actually is, this may constitute greenwashing. In Turkey, greenwashing is not merely an ethical problem. It may also be treated as misleading advertising, an unfair commercial practice and a violation of consumer protection rules.
The subject of environmental claims and greenwashing under Turkish advertising law has become especially important in recent years. The Turkish Ministry of Trade has expressly stated that consumers’ increasing environmental sensitivity has led some advertisers to use environmental claims in a way that may exploit consumers’ lack of information, and that necessary work is being carried out to prevent consumers from being misled through “greenwashing.”
Turkish advertising law does not prohibit environmental claims. A business may lawfully advertise the environmental benefits of its products or services if the claims are accurate, specific, verifiable and not misleading. The problem arises when the claim is vague, exaggerated, unsupported, incomplete or presented in a way that creates a broader environmental impression than the evidence justifies.
The main legal framework is based on Law No. 6502 on the Protection of Consumers, the Regulation on Commercial Advertising and Unfair Commercial Practices, the decisions of the Advertising Board, and the Guide on Advertisements Containing Environmental Claims. The Ministry of Trade announced that the Guide on Advertisements Containing Environmental Claims was adopted as a principle decision by the Advertising Board at its meeting dated 13 December 2022 and numbered 328, and that it was prepared to guide advertisers, advertising agencies and media organizations regarding environmental claims and visuals used in commercial advertisements and commercial practices.
In addition, important amendments to the Regulation on Commercial Advertising and Unfair Commercial Practices were announced in 2026. According to the Ministry of Trade, these amendments increased measures against the exploitation of environmental sensitivity. General expressions such as “environmentally friendly” may not be used without explanation, environmental claims must indicate which stage of the product or service life cycle they relate to, and certificates or approvals used in environmental advertisements must be supported by documents from competent institutions, universities, accredited organizations or independent testing and evaluation bodies.
This article explains the legal treatment of environmental claims and greenwashing in Turkey, including misleading environmental advertising, sustainability statements, life cycle claims, certificates, eco-labels, substantiation requirements, sector-specific risks, Advertising Board sanctions and practical compliance steps for businesses.
What Are Environmental Claims?
Environmental claims are statements, signs, visuals, labels, logos, symbols or messages that suggest a product, service, brand or business has environmental benefits or reduced environmental impact. These claims may appear in advertisements, product packaging, websites, social media posts, catalogues, e-commerce listings, sustainability reports, labels, influencer content, corporate campaigns and point-of-sale materials.
Examples of environmental claims include:
“Eco-friendly”
“Environmentally friendly”
“Climate friendly”
“Carbon neutral”
“Zero waste”
“Recyclable”
“Recycled content”
“Biodegradable”
“Compostable”
“Organic”
“Natural”
“Sustainable”
“Less plastic”
“Reduced carbon footprint”
“Made with renewable energy”
“Water-saving production”
“Nature-conscious packaging”
“Green product”
“100% recyclable packaging”
These expressions can strongly affect consumer decisions. Many consumers are willing to pay more or choose one brand over another because of environmental concerns. Therefore, environmental claims must be carefully controlled under advertising law.
An environmental claim may relate to different aspects of a product or service. It may concern raw materials, production methods, packaging, transportation, energy consumption, water use, waste management, recyclability, disposal, emissions, durability or the company’s broader sustainability policy. The legal problem often arises when the advertisement does not clearly explain which aspect the claim concerns.
For example, saying “environmentally friendly product” may create the impression that the entire product has a positive environmental profile. However, the actual evidence may relate only to the packaging. In such a case, the claim may be misleading unless the limitation is clearly explained.
What Is Greenwashing?
Greenwashing is the practice of presenting a product, service, company or commercial activity as more environmentally responsible than it actually is. It may occur through false claims, vague expressions, selective information, unsupported certificates, misleading visuals, exaggerated sustainability language or omission of important environmental limitations.
Greenwashing may be direct or indirect. A direct greenwashing claim may falsely state that a product is recyclable, biodegradable or carbon neutral. An indirect claim may use green colors, leaves, nature visuals, clean water imagery or environmental symbols to create an ecological impression without making a clear factual statement.
Greenwashing may also occur through selective emphasis. A company may highlight that a package uses less plastic while omitting that the product has significant environmental impacts at the production or disposal stage. A business may promote a minor sustainability improvement while implying that the entire brand is environmentally responsible. A product may be advertised as “natural” even though the term does not necessarily mean safe, sustainable or low-impact.
In Turkish advertising law, greenwashing is usually evaluated through the rules on misleading advertising and unfair commercial practices. The Advertising Board examines whether the environmental claim may mislead the average consumer and whether the advertiser can prove the claim. In 2024, the Ministry of Trade announced that the Advertising Board imposed administrative sanctions against companies in food, clothing and durable consumer goods sectors because general environmental claims such as “nature friendly,” “thinking about nature as much as you do,” and “climate friendly” were used without necessary information, caused uncertainty for consumers and could not be substantiated.
Legal Framework of Environmental Advertising in Turkey
Environmental advertising in Turkey is governed by the general advertising and consumer protection framework. The main sources are Law No. 6502 on the Protection of Consumers, the Regulation on Commercial Advertising and Unfair Commercial Practices, Advertising Board decisions and official guides.
The Advertising Board plays a central role. The Ministry of Trade states that the Advertising Board is the only administrative authority authorized to examine and supervise commercial advertisements and unfair commercial practices directed directly or indirectly at consumers in any medium. The Board may impose suspension, correction, administrative fines, temporary suspension and access blocking measures where unlawful advertisements are identified.
The Guide on Advertisements Containing Environmental Claims is especially important for green advertising. It was adopted by the Advertising Board as a principle decision and published to guide advertisers, advertising agencies, media organizations and other actors in relation to environmental claims and visuals used in commercial advertisements and commercial practices.
The 2026 amendments further strengthened this framework. The Ministry of Trade announced that environmental claims must be more specific and better documented. General environmental expressions cannot be used without explanation; the relevant stage of the product or service life cycle must be indicated; and certificates or approvals used in environmental advertisements must be proven through documents from competent institutions, universities, accredited bodies or independent testing and evaluation organizations.
Therefore, businesses should treat environmental advertising as a high-risk compliance area. A simple marketing phrase such as “eco-friendly” may require a detailed legal and technical analysis before publication.
General Environmental Expressions Must Be Explained
One of the most important rules concerns general environmental expressions. Terms such as “environmentally friendly,” “eco-friendly,” “green,” “nature-friendly,” “sustainable,” “climate-friendly” or “planet-friendly” are broad expressions. They may create the impression that the product or service has an overall positive environmental impact.
The Ministry of Trade announced that, under the 2026 amendments, general expressions such as “environmentally friendly” cannot be used in advertisements containing environmental claims without explanation. This rule is highly significant because many advertisements use broad green language without defining what it actually means.
A lawful environmental claim should be specific. Instead of saying “eco-friendly product,” a business should explain the basis of the claim. For example:
“Packaging contains 80% recycled plastic.”
“Product box is recyclable where local recycling facilities exist.”
“Manufactured using electricity from renewable sources.”
“Uses 30% less water during production compared to the previous model.”
“Bottle weight reduced by 25% compared to the 2024 packaging.”
Specific claims are safer because they tell consumers what the environmental benefit actually is. Vague claims are risky because they leave the consumer to assume a broader benefit.
A business should also avoid using environmental language as decoration. Green colors, leaves, trees, water drops, earth symbols and nature images may contribute to the overall impression. Even without an express written claim, visuals may create an environmental message. If that message is not supported, the advertisement may still be misleading.
Life Cycle Stage Must Be Identified
Another key rule is that environmental claims must indicate which stage of the product or service life cycle they relate to. The Ministry of Trade announced that environmental claims must specify the stage of the product or service life cycle concerned by the claim.
This is important because environmental impact can arise at many stages. A product may use sustainable packaging but have energy-intensive production. It may be recyclable but difficult to recycle in practice. It may be made from renewable materials but transported over long distances. It may reduce water use during use but generate waste at disposal.
The life cycle of a product may include raw material extraction, design, production, packaging, transportation, distribution, use, maintenance, recycling and disposal. A service may have environmental impacts through energy consumption, digital infrastructure, logistics, materials, travel or waste.
If an advertisement says “sustainable,” consumers may believe that the entire life cycle is sustainable. If the claim actually relates only to one stage, such as packaging, this must be made clear.
For example, the claim “environmentally friendly detergent” is too broad unless properly explained. A more specific claim would be “bottle made from 100% recycled plastic” or “formula designed to work at lower washing temperatures.” Similarly, “green hotel” may be misleading unless the hotel explains whether the claim relates to energy use, water saving, waste management, food sourcing or building certification.
Substantiation of Environmental Claims
Substantiation is the backbone of lawful environmental advertising. A business must be able to prove the accuracy of its environmental claims. If a claim cannot be proven, it should not be used.
The Ministry of Trade’s consumer information materials state that objective, measurable and numerical claims in advertisements must be proven through scientific tests, reports or documents. This principle is directly relevant to environmental advertising because many green claims involve measurable facts, such as recycled content, carbon emissions, energy savings, water reduction, biodegradability or recyclability.
The 2026 amendments specifically require that certificates and approvals mentioned in environmental advertisements must be substantiated with documents obtained from competent institutions, universities, accredited organizations or independent research, testing and evaluation bodies.
This means that internal marketing opinions are not enough. A company should not claim “carbon neutral” merely because it purchased offsets without reliable calculation and documentation. It should not claim “biodegradable” without scientific testing under relevant conditions. It should not claim “recyclable” if recycling is technically possible but practically unavailable to the average consumer.
Evidence should be available before the advertisement is published. Businesses should not launch a campaign first and search for proof later. If the Advertising Board requests substantiation, the advertiser should be able to submit documents showing that the claim was accurate at the time of publication.
Certificates, Eco-Labels and Approvals
Certificates and eco-labels are commonly used in environmental advertising. They may include organic certificates, recycled content labels, energy efficiency labels, carbon-neutral certificates, sustainability seals, green building certificates, forest management labels or third-party environmental approvals.
Certificates can help consumers make informed decisions, but they can also mislead consumers if they are vague, outdated, irrelevant, self-created or presented in an exaggerated way. A certificate should not be used to imply broader environmental benefits than it actually confirms.
For example, a packaging certificate should not be used to imply that the entire product is environmentally friendly. A company-level sustainability award should not be used to imply that each product has superior environmental performance. A certificate issued for one facility should not be used for products made in another facility.
Under the 2026 amendments, certificates and approvals mentioned in environmental advertisements must be proven with documents obtained from competent institutions, universities, accredited organizations or independent research, testing and evaluation bodies. This rule requires businesses to verify not only the existence of the certificate but also its relevance, scope and validity.
Businesses should keep copies of certificates, validity dates, issuing institution information, accreditation status, test reports and the exact claim supported by each document. They should also avoid using fake or confusing eco-labels designed to look official.
Common Types of Greenwashing in Turkey
Greenwashing can take many forms. The following examples are particularly relevant under Turkish advertising law.
The first type is vague green language. Expressions such as “eco-friendly,” “green,” “natural,” “climate friendly” or “nature-friendly” may be misleading if used without explanation.
The second type is unsupported environmental claims. A business may claim that a product is recyclable, biodegradable, sustainable or carbon neutral without reliable documentation.
The third type is selective disclosure. A company may highlight one small environmental benefit while ignoring more significant environmental impacts.
The fourth type is misleading visuals. Nature imagery, green colors, forests, oceans, animals and clean water visuals may create an environmental impression even if the product has no proven environmental advantage.
The fifth type is irrelevant claims. A business may advertise that a product does not contain a substance that is already legally prohibited or not normally used in that product category.
The sixth type is false certification impression. A self-created logo may be designed to look like an official environmental certificate.
The seventh type is unclear comparative claims. A product may be advertised as “better for the planet” without explaining what it is compared with or which environmental impact is reduced.
The eighth type is future promise without substance. A company may claim that it is “on the path to sustainability” without measurable commitments, timeframes or action.
Each of these practices may mislead consumers and create Advertising Board risk.
Environmental Claims in E-Commerce
E-commerce platforms are an important area for environmental advertising. Online sellers frequently use green labels, product badges, sustainability filters, eco-friendly categories, recycled material statements and environmentally themed product descriptions.
These claims must be accurate. If a marketplace creates a “sustainable products” category, it should define the criteria for inclusion. If a product is marked as “eco-friendly,” consumers should understand why. If a seller states that packaging is recyclable, the claim should be substantiated.
E-commerce platforms should also consider the role of consumer reviews and product descriptions. If sellers or users make environmental claims in product Q&A sections, descriptions or promotional banners, the platform and seller should monitor whether those claims are misleading.
Digital design can also create greenwashing risk. A product may be given a green badge or leaf icon without explanation. A search filter may suggest that all listed products meet environmental standards even if the criteria are unclear. Such practices may influence consumer decisions and should be legally reviewed.
Environmental Claims in Influencer Marketing
Environmental claims are increasingly used in influencer marketing. Influencers may promote sustainable fashion, eco-friendly cosmetics, reusable products, organic food, green travel, low-waste living, electric vehicles or environmentally responsible brands.
If an influencer receives payment, free products, discounts, event participation or another benefit, the advertising nature of the content must be disclosed under Turkish influencer advertising rules. However, disclosure of sponsorship is not enough. The environmental claim itself must also be accurate and substantiated.
An influencer should not say that a product is “zero waste,” “fully sustainable,” “carbon neutral” or “100% eco-friendly” unless the brand can prove the claim and the statement is legally appropriate. Influencers often use casual language, but casual wording can still create a factual advertising claim.
Brands should provide influencers with precise wording. Instead of allowing broad statements such as “this brand is completely sustainable,” the brand should instruct the influencer to use verified claims such as “the packaging contains recycled material” or “the product is certified under X standard,” if true and properly documented.
Comparative Environmental Claims
Comparative environmental claims are especially risky. A business may claim that its product is greener, cleaner, more sustainable, less polluting or better for the environment than competing products. Such claims may be lawful only if they are objective, verifiable, not misleading and not unfair to competitors.
The Ministry of Trade’s consumer information materials state that comparative advertisements may be made only under conditions including objective comparison of material, essential, verifiable and typical characteristics, and proof of objective, measurable and numerical claims with scientific tests, reports or documents.
For example, a claim such as “30% lower carbon emissions than our previous model” may be safer than “the greenest product in Turkey,” provided that the calculation is reliable and the comparison is clearly explained. The advertiser should specify the comparison basis, measurement method, period, scope and relevant life cycle stage.
Broad comparative claims such as “better for nature than other brands” may be risky because they are difficult to prove and may create a general superiority impression. Comparative environmental advertising should be drafted with technical precision and legal caution.
Sector-Specific Greenwashing Risks
Environmental claims appear in many sectors, but some industries are particularly sensitive.
In the fashion and textile sector, claims such as sustainable fashion, recycled fabric, organic cotton, low-impact dyeing and ethical production must be supported. A garment made with a small percentage of recycled fiber should not be advertised as fully sustainable.
In the food and beverage sector, claims such as organic, natural, local, sustainable farming, eco-packaging or climate-friendly production may require specific documentation. Organic claims may also be subject to sector-specific rules.
In the cosmetics sector, terms such as natural, clean, vegan, cruelty-free, biodegradable and eco-friendly packaging may affect consumer decisions. These claims should be precise and substantiated.
In the automotive sector, electric, hybrid and low-emission claims should be accurate and should not ignore relevant limitations such as battery production, electricity source or real-world usage conditions.
In the real estate and construction sector, green building, energy efficiency, sustainable project and environmentally responsible development claims should be supported by project documents, certificates and technical reports.
In the energy sector, renewable energy, carbon reduction and clean energy claims should be carefully documented because they can significantly affect consumer and investor perception.
Advertising Board Enforcement
The Advertising Board actively monitors environmental advertising. In June 2024, the Ministry of Trade announced that the Advertising Board reviewed 175 files at its 346th meeting, found 147 files unlawful, imposed suspension sanctions and administrative fines totaling 20,100,269 TL, and decided access blocking in 3 files. The same announcement specifically stated that environmental claims were being supervised because of their effect on consumer preferences.
The Ministry also stated that the Board imposed sanctions on companies operating in food, clothing and durable consumer goods sectors because general environmental claims were used without necessary information, caused uncertainty for consumers and could not be proven.
These decisions show that environmental advertising is not a theoretical compliance issue. The Advertising Board may examine green claims, request evidence, evaluate consumer perception and impose sanctions where the claim is vague, unsupported or misleading.
Sanctions for Greenwashing
Greenwashing may lead to administrative sanctions under Turkish advertising law. The Advertising Board may order suspension of the advertisement, correction by the same method, administrative fines and temporary suspension. In online cases, the Board may also decide access blocking for the relevant part, section or entirety of a website containing unlawful advertisements.
The Ministry of Trade’s consumer information materials also state that administrative fines vary according to the medium in which the advertisement is published and that if the same violation is repeated within one year, fines may be imposed up to ten times the ordinary amount.
In addition to administrative sanctions, greenwashing may create unfair competition risk. Competitors may argue that a business gained an unfair advantage by using false sustainability claims. Consumers may also complain if they purchased products based on misleading environmental representations. Reputational damage may be particularly severe because consumers who care about sustainability may react strongly to deceptive green marketing.
Practical Compliance Checklist for Environmental Claims
Businesses using environmental claims in Turkey should apply a strict compliance checklist before publication.
First, identify the exact environmental claim. Is the advertisement claiming recyclability, biodegradability, carbon neutrality, reduced emissions, sustainable sourcing, organic content, renewable energy use or another benefit?
Second, avoid vague expressions. Do not use general claims such as “eco-friendly” or “green” without clear explanation.
Third, specify the life cycle stage. Explain whether the claim relates to raw materials, production, packaging, transportation, use, recycling or disposal.
Fourth, collect evidence before publication. Scientific tests, technical reports, certificates and independent evaluations should be available.
Fifth, verify certificates. Check the issuing body, validity period, scope, accreditation and relevance of each certificate.
Sixth, avoid misleading visuals. Nature imagery and green symbols should not create a broader impression than the evidence supports.
Seventh, review comparative claims carefully. Comparisons should be objective, measurable, verifiable and clearly explained.
Eighth, train influencers and agencies. Sponsored environmental claims should be clear, accurate and limited to verified statements.
Ninth, preserve records. Keep claim files, test reports, certificates, approval records, screenshots and campaign materials.
Tenth, monitor post-publication use. If a claim becomes outdated or inaccurate, remove or correct the advertisement promptly.
Best Practices for Businesses
A strong environmental advertising compliance system should involve marketing, legal, sustainability, production and quality control teams. Environmental claims often depend on technical facts. Marketing teams should not create sustainability language without input from the departments that understand the product’s materials, supply chain, emissions and certifications.
Businesses should create an internal green claims policy. This policy should define which terms may be used, what evidence is required, who approves environmental claims, how certificates are verified and how claims are updated when circumstances change.
Claims should be written in plain language. Consumers should not need technical expertise to understand the environmental benefit. At the same time, the claim should not oversimplify complex environmental issues in a misleading way.
Businesses should also be cautious with corporate sustainability statements. A company may publish long-term sustainability goals, but those goals should not be presented as if they have already been achieved. Future commitments should be realistic, measurable and supported by action plans.
Conclusion
Environmental claims and greenwashing under Turkish advertising law are now a major compliance issue. Consumers increasingly care about environmental impact, and businesses naturally want to communicate sustainability efforts. However, environmental sensitivity must not be exploited through vague, unsupported or misleading green claims.
Turkish law allows environmental advertising, but it requires accuracy, transparency and substantiation. General expressions such as “environmentally friendly” must not be used without explanation. Environmental claims must indicate which stage of the product or service life cycle they relate to. Certificates and approvals used in environmental advertisements must be supported by reliable documents from competent institutions, universities, accredited organizations or independent testing and evaluation bodies.
The Advertising Board’s enforcement practice shows that greenwashing is actively monitored. Claims such as “nature friendly,” “thinking about nature as much as you do,” and “climate friendly” may create legal risk if they are general, unclear and unsupported.
For businesses operating in Turkey or targeting Turkish consumers, environmental advertising should be treated as a legal and technical compliance matter, not merely as a branding choice. A lawful green claim should be specific, evidence-based, limited to the actual environmental benefit and understandable for consumers.
The safest approach is simple: do not claim more than you can prove. When environmental claims are accurate and transparent, they can help consumers make informed choices and reward genuinely sustainable business practices. When they are vague or exaggerated, they may lead to greenwashing allegations, Advertising Board sanctions, consumer complaints, unfair competition disputes and reputational harm.
In the Turkish market, credible sustainability communication requires more than green visuals and attractive slogans. It requires legal accuracy, scientific support, honest wording and respect for consumer trust.
