The clothing industry can pollute the environment in many ways, including:

• Water pollutionTextile production is estimated to be responsible for 20% of global clean water pollution. When clothes are washed, chemicals from the detergent and the clothes themselves can be released into the water. Washing synthetic clothes can also release microplastics into waterways, which eventually end up in the ocean.
• Greenhouse gas emissionsThe fashion industry is responsible for about 10% of global carbon emissions. Animal-based textiles like wool, which are often used in fast fashion, also contribute to greenhouse gas emissions.
• Textile wasteLess than half of used clothes are recycled or reused. When clothes are discarded, they can decompose and release chemicals and gases that pollute the air, soil, and groundwater. Unwanted clothing can also clog gutters, preventing water from flowing properly.
• Hazardous chemicalsTextile mills often use hazardous chemicals that can endanger the health of workers and consumers. These chemicals are sometimes disposed of in local waterways, which can harm wildlife and local communities.
