The textile and apparel industry is one of the largest consumers of water and energy while contributing significantly to environmental pollution. Garment finishing, especially in denim washing, involves excessive use of water, chemicals, and energy, leading to a substantial environmental footprint. To address these challenges, Jeanologia, a Spanish company specializing in sustainable textile solutions, developed the EIM (Environmental Impact Measurement) Score. This tool helps brands and manufacturers assess, monitor, and improve their environmental impact in garment finishing processes.
