EXHIBITION T-SHIRT What’s behind… What’s behind… Cotton fiber is the most used textile fiber in the world. 26 million tons of cotton are produced each year. This is equivalent to : Only when looking at the whole product cycle are we able to make truly informed decisions about which products are preferable and how to substantially reduce their impacts. TODAY, WE SEE BEHIND THE CURTAIN OF A T-SHIRT, COFFEE AND CHOCOLATE, OUR FAVORITE SOURCE OF ENERGY. 1 t-shirt 3.5 Kg 18 t-shirts per person per person 1.3 m x 1.3 m Climate change Wash correctly : It takes energy to grow, manufacture and transport a cotton t-shirt. But a lot of energy and emission can be avoided by washing and drying sustainably. white medium cotton HOW MANY T-SHIRTS DO YOU OWN ? DO YOU KNOW HOW MUCH ENERGY IS USED TO PREPARE A CUP OF COFFEE ? HOW MUCH WATER IS USED TO PRODUCE YOUR T-SHIRT ? To be able to grasp the full picture we need to account for all energy, materials and emissions used. WHAT IS THE ENVIRONMENTAL FOOTPRINT OF A T-SHIRT ? WHAT IS THE LIFE CYCLE OF A T-SHIRT ? land 457 91 h 35 km water cycling (energy) driving a passenger car Lifetime of a t-shirt : The impact of a t-shirt which is used just once is incredibly high. In contrast, your favourite t-shirt which is worn over and over again is way more sustainable. Water use Land use Energy use Cotton cultivation Growing cotton is the first step in the life of a t-shirt. The main producers are China, India and the USA. Use & end-of -life Manufacturing Once cotton fibers leave the farm, they travel through stages of grinning, textile production, dyeing and garment assembly to finally become a t-shirt. Manufacturing Cotton cultivation Use and end-of-life The t-shirt is bought, worn and laundered repeatedly until meeting its end-of-life. Land use Water use Energy use Manufacturing : The way from cotton fiber to your t-shirt is long. In addition to the impacts of long transportation distances, the various processing steps, especially ginning (separting cotton fibres) and dyeing, consume a lot of energy and seriously impact water quality. Cotton cultivation : The main impacts of cotton production are land use, water use, the use of fertilizers and pesticides. Only 4% of all clothes are organically produced. Make sure to look for sustainably sourced cotton when you buy a t-shirt. Climate change Established by Quantis and ecoinvent
