Climate change is upon us, and it’s everyone’s responsibility to do what they can to reduce our carbon footprint. Reusable shopping bags, not using disposable paper plates and cutlery, biking or walking short distances instead of driving – these are all great ways to be a little nicer to our earth.

But did you know you can also make an environmental difference with your clothing?

Cotton and other fabrics aren’t necessarily bad for the environment – they are biodegradable and will break down over time. But it turns out that clothing made of bamboo fabrics are actually the most environmentally friendly in the world. That’s because it’s generally grown with almost no chemical inputs (think pesticides).

Hemp, cotton, and silk are all also relatively eco-friendly since they are biodegradable and made of natural fibers as well. The main difference is that in some cases, there are more chemicals used to convert the raw material into fibers to crate fabric.
