Green marketing: what it is, examples and how to avoid greenwashing

Green marketing is promoting a product, service or company on the basis of its real environmental benefits, such as lower emissions, recycled materials, less packaging or a longer product life. It works when the claims are specific and backed by evidence. It backfires, and can break the law, when the claims are vague or exaggerated.

That second point has become more important. New EU rules that apply from 27 September 2026 ban vague environmental claims in consumer marketing. The UK competition regulator can now fine businesses directly for breaking consumer law, and the US regulator has published guidance on what a fair green claim looks like.

What are the goals of green marketing?

Green marketing has two sides that must match:

1. Communicating environmental benefits to customers, investors, employees and partners.
2. Actually delivering those benefits, by changing materials, packaging, production, logistics, energy use or how long a product lasts.

Marketing that only does the first is greenwashing. The real work is in the second, and good green marketing tells the story of that work honestly.

What are the benefits of green marketing?

• Differentiation. A credible environmental advantage can set you apart in a crowded market.
• Access to buyers who require it. Some customers, public bodies and large companies include environmental criteria when they choose suppliers.
• Trust. Specific, verifiable claims build credibility with customers and partners.
• Innovation. Designing for lower impact pushes teams to rethink materials, processes and business models, such as repair or take-back programs.
• Lower costs. Using less energy, material and packaging can also reduce operating costs.

Why does green marketing matter in B2B?

In B2B, sustainability often shows up in the sales process rather than in advertising. Under the GHG Protocol's Scope 3 standard, a company measures the indirect emissions in its value chain, upstream and downstream, from the goods it buys to the disposal of the products it sells. The standard encourages companies to work with suppliers and customers to reduce those emissions.

For suppliers to such companies, that can mean:

• Procurement questionnaires that ask about emissions, energy use and environmental policies
• Requests for product-level data, such as the carbon footprint of what you deliver
• Contract terms or supplier codes of conduct that include environmental commitments

Sales and marketing teams that can answer these questions clearly, with data, have an advantage. Vague answers or slogans do not survive a procurement review.

Green marketing examples

Patagonia: long-term commitments, not slogans

Outdoor clothing company Patagonia has committed 1% of its total sales to environmental groups since 1985, through One Percent for the Planet. In 2017 it created Worn Wear, a trade-in and exchange program. Its marketing works because it points to long-running actions customers can check, rather than to general claims about being green.

Volkswagen: a greenwashing warning

The opposite example comes from Volkswagen's "clean diesel" campaign. The US Federal Trade Commission alleged that for seven years the company advertised diesel cars as low-emission and environmentally friendly while they contained illegal defeat devices that hid high emissions during government tests. Under FTC orders, Volkswagen and Porsche repaid more than $9.5 billion to car buyers. The lesson for any marketer: an environmental claim is a factual claim, and it must be true.

What are the rules for environmental claims?

The rules differ by market, so check them in each market where you sell.

European Union

The Empowering Consumers for the Green Transition Directive (EU) 2024/825 applies from 27 September 2026. In consumer marketing it bans:

• Generic environmental claims, such as "environmentally friendly", "eco-friendly", "green" or "biodegradable", unless the trader can show recognised excellent environmental performance relevant to the claim
• Sustainability labels that are not based on a certification scheme or set up by public authorities
• Claims based on carbon offsetting that a product has a neutral, reduced or positive impact on the climate

EU countries had to put the rules into national law by 27 March 2026, so the details and enforcement can differ by country.

What happened to the EU Green Claims Directive?

In March 2023 the Commission proposed a separate Green Claims Directive, with rules on how companies prove and communicate environmental claims. On 20 June 2025 the Commission announced that it intends to withdraw it, and the next round of negotiations on it, set for 23 June 2025, was cancelled. As of 1 November 2026 the proposal has not been withdrawn, but it has not moved either: the Commission lists it as pending, and the European Parliament's tracker marks it as blocked, waiting for the Council's position. It is not law, so the EU rules that apply today are those of Directive 2024/825.

United Kingdom

The Competition and Markets Authority's Green Claims Code sets out six principles. Claims must:

1. Be truthful and accurate
2. Be clear and unambiguous
3. Not omit or hide important relevant information
4. Make fair and meaningful comparisons
5. Consider the full life cycle of the product or service
6. Be substantiated

The CMA says the guidance also applies, to a more limited extent, to businesses marketing to other businesses.

Since 6 April 2025, the Digital Markets, Competition and Consumers Act 2024 has let the CMA enforce consumer law directly. It can decide itself whether a business has broken the law, without going to court, and fine it up to 10% of its global turnover or £300,000, whichever is greater. In January 2026 the CMA published guidance on green claims across the supply chain. It expects brands and suppliers to make sure the claims they make are accurate, and suppliers to give retailers the assurance they need to make accurate claims themselves.

United States

The FTC's Green Guides, first issued in 1992 and last revised in 2012, explain how marketers can avoid misleading environmental claims, how consumers are likely to read claims such as "recyclable", and how to qualify them. The FTC opened a review of the Guides with a request for comments on 14 December 2022 and held a workshop on "recyclable" claims in May 2023. As of 1 November 2026, it has not published proposed or final changes, so the 2012 Guides are still the current version.

How do you avoid greenwashing?

• Be specific. "Made with 60% recycled aluminium" says something. "Eco-friendly" does not. Only use numbers you can prove.
• Have the evidence before you publish. Keep data, test results or certifications on file for every claim.
• Look at the whole life cycle. Do not highlight one green feature while ignoring a bigger impact elsewhere.
• Do not overstate small changes. A recyclable lid does not make the whole product sustainable.
• Be careful with "carbon neutral" and offsets. In the EU, consumer claims of this kind based on offsetting are now banned. Elsewhere, explain exactly what you have reduced and what you have offset.
• Use recognised certifications, and explain what they cover.
• Make future targets credible. A net-zero goal for a future year needs a plan, interim steps and regular progress reports.
• Align sales and marketing. Make sure sales decks, proposals and questionnaire answers say the same thing as your website. Our guide to sales and marketing alignment can help.

How do you build a green marketing strategy?

1. Measure first. Know your actual footprint and where your product genuinely performs better.
2. Pick claims you can prove. Focus on the few benefits that matter most to your target audience.
3. Tell the story of the work. Explain what you changed, why and what it achieved.
4. Make the data easy to find. Publish a clear page with your methods, data and certifications, and give your sales team a short fact sheet.
5. Review regularly. Update claims when products, suppliers or rules change.

Green marketing is not a campaign theme. It is a promise that your product and company have to keep. For related approaches, see our guides to differentiated marketing and building brand equity.
