Happy Earth Day! The theme for this year’s earth day is Invest In Our Planet, an important message we can take and influence our decisions towards a more sustainable future.

Over 8% of greenhouse gas emissions are caused by the fashion industry, which exceeds air travel and maritime travel emissions combined. In addition to the carbon emissions, the fashion industry is estimated to create over 92 million tonnes of waste every year, most of which end up in landfills, including waste plastics and polyester, which won’t biodegrade for hundreds of years.

Here at Ecothes we believe that making small changes in our consumer habits, buying fewer clothes, wearing your clothes more, and supporting sustainable and ethical brands when you shop helps contribute to the movement towards a more sustainable future.

We have some great resources if you’re looking to learn more about the fast fashion industry’s damaging effects on the planet. Our guides are written to help you discover new sustainable brands promoting the use of eco-friendly materials and ethical production.

Below we’ve highlighted a few of our favorite brands for you to discover this earth day!
