I've been trying to be more conscious about the environmental impact of my fashion choices, how eco-friendly is Mango's clothing?

The information on Mango's website and the comments in our database confirm that Mango has taken steps toward sustainability, but it remains a work in progress. They are devoted to employing more sustainable materials, such as organic cotton, recycled polyester, and Tencel, and aim to source 100% of their cotton and polyester sustainably by 2025.
They're also focused on circular design by developing items that can be reused, recycled, or composted, and they've even started a "Take Back" program where customers can return unwanted clothes for recycling.

This is the information we have, but if you have more insights from your experience, please share in the comments.
