Understanding Greenwashing – and How to Use It in Your Teaching

What is Greenwashing?

Greenwashing is when a company or organization makes misleading claims about how environmentally friendly their products, practices, or policies are. It’s a marketing strategy that gives the impression of sustainability without making real changes that benefit the environment. For example, a product may be labeled “eco-friendly” or “natural” without clear evidence to back it up, or a company might highlight one small green initiative while continuing harmful practices elsewhere. It’s like putting a “green label” on a product or service to attract eco-conscious consumers, while behind the scenes, their practices may still harm the environment.

Examples:

• A fast fashion brand advertises a “sustainable collection” made from recycled materials, while 95% of their products are still produced in wasteful and polluting ways.
• A petrol company promotes its investments in renewable energy, while the vast majority of its business remains in fossil fuels.

Why is this topic important?

In a world increasingly concerned with climate change and sustainability, students are surrounded by messages about being “green.” Teaching them to critically evaluate these messages helps them become informed consumers and responsible citizens. Greenwashing is a great topic to foster critical thinking, media literacy, and ethical awareness.

How Can Teachers Use This Topic in School?

1. Critical Thinking Activities
   • Ask students to compare real advertisements and identify which claims might be greenwashing.
   • Use checklists (e.g. “How to spot greenwashing”) to guide their analysis.
   • Discuss questions like: How can we know if a company is really sustainable? Why might companies want to appear greener than they are?
2. Cross-Curricular Connections
   • Science: Explore the environmental impact of products and how scientific evidence supports or contradicts green claims.
   • Geography: Examine global production chains and their environmental costs.
   • Economics/Business: Investigate corporate responsibility and ethical marketing.
   • Language/Media Studies: Analyze persuasive techniques in advertising.
3. Project Ideas
   • Have students research and present on real cases of greenwashing.
   • Create a classroom campaign to educate peers about greenwashing.
   • Let students redesign a misleading product label to make it more honest.
4. Real-World Relevance

Connect to local businesses or school initiatives. Invite students to audit how green their own school is—and whether any claims may unintentionally mislead.

What Can Teachers Do With This Topic?

Here are concrete project ideas you can use across subjects and age groups:

1. Greenwashing Detective Project

Goal: Teach students how to spot greenwashing.

Steps:

• Introduce common greenwashing tactics (vague language, irrelevant claims, hidden trade-offs).
• Ask students to bring in product ads or packaging with green claims.
• Use a checklist (e.g. “The 7 Sins of Greenwashing”) to analyze them.
• Let students create a “Greenwashing Wall of Fame” with examples and explanations.

Extension: Compare real examples with genuinely sustainable companies.

2. Make Your Own Advertisement – Ethically!

Goal: Understand persuasive techniques and ethics in advertising.

Steps:

• Discuss how companies persuade consumers using words, colors, and symbols.
• Show examples of greenwashing and honest green marketing.
• In groups, students choose a product and make two ads:
  a) A greenwashed version
  b) An honest, responsible version
• Present and discuss: Which is more persuasive? Which is more ethical?

3. School Sustainability Audit

Goal: Connect global environmental issues with local action.

Steps:

• Have students examine how “green” the school is: recycling, energy use, canteen packaging, etc.
• Compare school actions with how the school presents its sustainability (e.g. on websites or brochures).
• Identify where claims are well-founded and where improvements are possible.
• Propose changes based on findings (e.g. reduce plastic use, improve transparency).

Bonus: Present results to school leadership and initiate a student-led campaign.

4. Case Study Debate

Goal: Understand both sides of real-world controversies.

Steps:

• Research a real company accused of greenwashing (e.g. H&M, Nestlé, Shell).
• Split students into two teams: defense and prosecution.
• Debate: Has this company made genuine progress or is it misleading the public?
• Emphasize evidence-based arguments and respectful discussion.

Tips for Teachers

• Use current examples: Greenwashing is constantly in the news—make it relevant.
• Encourage skepticism, not cynicism: Help students see that critical thinking can lead to constructive action.
• Make it interdisciplinary: Link to environmental science, language analysis, consumer education, and ethics.
• Empower action: End with student-led initiatives that go beyond the classroom.
