Organic cotton brand Cotonea: Transparency offensive in environmental accounting
On the occasion of World Cotton Day 2024, Cotonea presented comprehensive CO2 and energy analyses of a total of 460 fabrics for the first time. Unlike conventional life cycle assessments, the brand analyzes its entire value chain from the cotton plant to the finished fabric and measures energy consumption and associated CO2 emissions in detail. This enables comprehensive transparency and creates comparability.
“Our analyses and the consistent use of renewable energies along the entire supply chain show that some of our fabrics still act as CO2 sinks even after finishing. This is a clear signal of our commitment to environmental protection,” says Roland Stelzer, Managing Director of the long-established company Elmer & Zweifel and founder of the Cotonea brand.
Precise data
Cotonea examined the CO2 and energy footprint for a total of 460 different fabrics so precisely that even differences in colors, such as yellow or black, could be determined exactly. Only the energy consumption for the yarn dyeing required for a few fabrics and means of transportation such as trucks, ships and trains as well as the assessment of primary energy sources are based on average values. “Instead of blanket CO2 footprints or LCAs, we at Cotonea document exactly how our fabrics are manufactured and how much CO2 and energy are consumed in the individual production stages,” emphasizes Stelzer.
Some fabrics act as CO2 absorbers even after finishing. This is partly due to the natural CO2-binding properties of cotton fibers in organic cultivation and partly due to the use of hydropower and solar systems in the production facilities.
Advanced technology for comprehensive sustainability
For the analysis, Cotonea, with the support of the Industrieverband Veredelung - Garne - Gewebe - Technische Textilien e.V. (IVGT), used the “Umberto” life cycle assessment software, in which all relevant steps of the production process have been modeled and mapped. The calculations comply with ISO standards 14040 and 14044 for life cycle analysis (LCA). Since the end of 2012, Cotonea has provided items with a product passport that shows the individual production steps. In 2020, the organic cotton brand contributed its supply chain expertise to the “Textile Trust” blockchain project by IBM and Kaya & Kato, which was supported by the German Federal Ministry for Economic Cooperation and Development.
