Sustainable fashion brands care about the environment and treating people fairly. They use materials that are good for the planet, like organic cotton and recycled fabrics, and make sure workers are treated well. Sustainable fashion brands often make classic, long-lasting clothes, support local craftspeople, and try to reduce waste by recycling old clothes. They also focus on using less water and energy when making their products and sometimes offer vegan and cruelty-free options. By being open and responsible, they aim to create a more eco-friendly and fair fashion industry.

The fashion industry, including its supply chain, ranks as the third largest polluter after the food and construction industries. It contributes 10% of global greenhouse gas emissions, releasing 1.2 billion tonnes of carbon dioxide annually, which is more than the combined emissions from the shipping and aviation industries. Sustainable fashion brands are addressing these environmental impacts by promoting eco-friendly practices and reducing their carbon footprint.
