LONDON – By wearing a garment twice as many times, its environmental impact can be halved according to research which provided new and updated life cycle assessments (LCAs) of clothing consumption. For example, the research noted that on average, a T-shirt is used 30 times and washed 15 times. If this t-shirt is instead used 60 times the climate impact can be cut by 49 per cent.
An LCA was used to evaluate the environmental impact of six garments: a T-shirt, a pair of jeans, a dress, a jacket, a pair of socks, and a hospital uniform. Researchers used indicators of climate impact such as energy use, water scarcity, land use impact on soil quality, freshwater ecotoxicity, and human toxicity.
