Inversa is looking to preserve coastal ecosystems by using lionfish, an invasive species destroying coral reefs, to craft leather. As one of a growing number of 'next generation' materials, it provides the fashion industry with a way to evolve production processes and keep up with consumers' values.

As people turn to sustainable lifestyles, they're also keen to buy alternative materials to leather. Enter Dole, the world’s biggest fruit and vegetable producer whose collaboration with Ananas Anam is turning pineapple leaves into vegan leather, tackling food waste issues in the process.

Retailers’ sustainability initiatives show that shoppers don’t just want cheap, fast fashion – ethical and eco-savvy values are important too. But are visibly mended sweaters and ‘sneaker cleaning’ services just an updated version of the ‘It bag’, or are people ready to adopt low-impact lifestyles?

Consumers’ changing priorities are forcing luxury brands to take stock of their impact, and display sustainable credentials. The Butterfly Mark is awarded by Positive Luxury to brands that meet sustainable and ethical criteria.
