The run-up to Black Friday, Diwali sales and year-end offers is when advertising peaks, and eco claims have become a selling point. Some are genuine. Many are vague, misleading or irrelevant. Regulators have taken notice: India's consumer protection authority issued guidelines on greenwashing in 2024, and the European Union has been tightening rules on generic environmental claims.

Our guide to eco certifications covers trustworthy labels. These are the warning signs.

Red flag 1: vague words

Words like eco-friendly, green, natural, conscious and sustainable, with nothing specific behind them, tell you almost nothing. A genuine claim says what is better, by how much, and how it was measured.

Red flag 2: a small green feature on an ordinary product

A product made mainly of new plastic but with 'recycled packaging', or a fast-fashion line with one 'conscious' collection, highlights a tiny improvement to distract from the whole.

Red flag 3: claims that are irrelevant

'CFC-free' on an aerosol is true but meaningless, because CFCs were banned decades ago. 'PFOA-free' on a non-stick pan says nothing about other PFAS coatings.

Red flag 4: carbon neutral through offsets alone

Products and brands claiming to be carbon neutral often rely on buying offsets rather than reducing emissions. The quality of offsets varies widely, and some have been found to deliver far less than claimed.

Red flag 5: invented labels

A leaf logo or a badge designed by the brand itself is not a certification. Real certifications name an independent body and usually have a way to verify the claim.

Red flag 6: buy more to save the planet

Any message that encourages you to buy more in the name of sustainability deserves suspicion. The most sustainable purchase is usually the one you do not make.

Questions to ask

  • What exactly is better about this product?
  • Is the claim verified by an independent body?
  • Does it cover the whole product, or one part?
  • Would I buy this if the green claim were removed?

Reporting misleading claims

In India, misleading advertisements can be reported to the Advertising Standards Council of India and consumer complaints can go through the national consumer helpline. Reporting helps more than you might think; regulators act on patterns of complaints.

For more of this kind of testing, the eco-friendly product guides hub collects everything we've tried in that area.

Frequently asked

Do I need to buy anything to get started?

No. Every method here begins with what is already in your cupboards. We only recommend a purchase when something has genuinely worn out, and we say what it should cost.

How do you test the things you write about?

Minimum four weeks of ordinary household use, with notes. For anything involving energy or money we use a plug-in meter and record the readings before and after.

Are your recommendations paid for?

Never. Brands cannot buy placement. Some outbound links are affiliate links, which we mark, and they do not change what makes the list.

What if a method doesn't work in my home?

Write to us. A surprising amount of our best material comes from readers explaining why something failed in a flat, a shared house or a very cold winter.
