Age group: 11-15

This page provides you with a snapshot of this activity that teaches students how companies and organisations use ‘Greenwashing’ to make their company, products or services seem environmentally friendly when in reality they are not. Learn how to use the 10 signals to find out if an advertisement is greenwashed. Test your knowledge and become an expert at spotting greenwashing so that you never get tricked again! Discover how to become a conscious consumer and buy products that are good for the environment and share this with your family and friends.

We recommend that you use the ‘Introduction to Solid Waste’ activity before any of the other activities as it is a good starting point for students to learn about waste. It provides a comprehensive overview of how waste is generated and its impacts on animals, the environment and us.

1 Class discussion (10-15 minutes)

Write the terms ‘conscious consumerism’ and ‘greenwashing’ on the board. Lead a brief discussion with students about these terms by asking the following questions:

  1. What is conscious consumerism?
  2. How can we be conscious consumers?
  3. What is greenwashing?
  4. Why is greenwashing a problem?
  5. What can we do?



What is conscious consumerism?

  • Everything we buy has an impact on the environment.
  • Conscious consumerism focuses on making better/more informed choices on what you buy in order to avoid the negative impacts that consumerism has on the planet (natural resource use and pollution).
  • We all want to be conscious consumers and buy products that are good for the environment. So how do we do it?
