Polyester production increases despite fashion industry climate goals

The use of polyester fibers, which are derived from fossil oil, is increasing despite the fashion industry's stated goals to reduce greenhouse gas emissions. According to data from Textile Exchange, total synthetic fiber production has doubled between 2000 and 2024, reaching 132 million tons in 2024.

Polymer technology expert Dan Åkesson, a professor at Borås University, suggests the textile industry should focus more on recycling its own products. He notes that less than one percent of polyester is currently recycled, and many garments are made of blended materials or contain dyes that create technical challenges for recycling. This lack of effective waste management often leads to clothing being incinerated, releasing carbon dioxide into the atmosphere.

Sandra Roos, sustainability director at Kappahl, argues that polyester has a long lifespan due to its durability. She suggests that the primary climate impact occurs during the manufacturing processes—such as dyeing, weaving, and sewing—and emphasizes the need to transition to renewable energy in factories to achieve climate goals.
