Simple Guide to Sustainable Fashion Certifications

You’ve probably bumped into their logos on some fairtrade brands' websites, but what do these sustainable fashion certifications mean in practice? And can you actually trust them?

What is a sustainable fashion certification?

A sustainable fashion certification is given by an independent third party to confirm that a brand meets specific standards from an eco-friendly or ethical point of view.

In an industry that’s plagued by greenwashing, ethical fashion certifications are incredibly helpful.

After all, anyone can say that their clothes are ‘green’, ‘eco’, or other unquantifiable and vague adjectives. When we talk about specific benchmarks and get a third party involved, however, you can trust that brand with all your eco-conscious heart.
