What does sustainable fashion actually mean? In short, it’s an umbrella term for clothes that are created and consumed in a way that can be, quite literally, sustained, while protecting both the environment and those producing garments. 

That’s why cutting CO2 emissions, addressing overproduction, reducing pollution and waste, supporting biodiversity, and ensuring that garment workers are paid a fair wage and have safe working conditions, are all crucial to the sustainability matrix.
