The Verdict
What is greenwashing?
The practice of making a product, service or company appear more environmentally friendly than it really is — through vague claims, fake eco-labels, selective data, misleading imagery or unsupported promises.
Mossy is a communication tool, not a courtroom. It surfaces the gaps so brands can communicate sustainability more honestly.
Numbers, scope, dates — no vague hand-waving.
Link to data, methods, or third-party assurance.
Green leaves don't equal a green product.
Honest beats heroic. Acknowledge what you haven't solved.

See Pro plans →“We used Mossy to check the sustainability communications across the websites of our Group companies, advertising campaigns and product packaging labels. The tool showed us the non-compliance risk for each item against the main regulatory references. We received a concrete, easy-to-implement action plan — which helped us share findings across responsible teams more effectively. For the agri-food sector, Mossy promotes transparency in an industry strongly affected by climate change and growing sustainability demands from both clients and consumers.”
Both tools are grounded in the PhD research of Dr. S. Rêgo, Universidade do Minho.
