The Environmental Cost of Getting Dressed

The fashion industry is one of the planet's biggest polluters, responsible for 4% of global GHG emissions, and 35% of ocean microplastics. More than half of clothing relies on synthetics like polyester—cheap, fossil-fuel-derived fibers that shed microplastics with every wash. These tiny particles are choking marine ecosystems and entering the food chain. They contaminate seafood, drinking water, and even human blood and organs, raising risks of inflammation, hormonal disruption, and long-term health issues. However, innovative companies are slashing synthetics through material shifts and recycling breakthroughs.
Reformation is one company leading the charge. Under Chief Sustainability Officer Kathleen Talbot, the brand set a hard target to reduce all synthetics, both virgin and recycled, to less than 1% of its fiber mix by 2025. Through a pioneering partnership with Ambercycle, they launched collections using cycora®, a high-performance recycled material made from discarded synthetics that would otherwise head to landfills. By the end of 2024, they achieved 98% of materials as recycled, regenerative or renewable, with total synthetics at 10% of fiber use.
Gudrun Messias at Adidas has driven the shift to nearly 99% recycled polyester where technically possible and is exploring plant-based bioplastics for shoe soles. Levi Strauss & Co. Chief Sustainability Officer Jeffrey Hogue oversees advances in chemical recycling and preferred fibers that minimize synthetic dependency. The company’s longstanding Water<Less techniques, for example, have achieved substantial water reductions in denim finishing—up to 96% in certain processes compared with conventional methods.
The GHG emissions of the industry account for approximately 4% of the global total. Emissions are overwhelmingly Scope 3, stemming from supply-chain activities rather than brand-owned operations. The most detailed and widely referenced lifecycle breakdown comes from McKinsey’s analysis of 2018 data:
Stage | % Share |
Material production | 38% |
Wet processes | 15% |
Yarn preparation | 8% |
Fabric preparation | 6% |
Garment assembly | 4% |
Product use | 20% |
Transport | 3% |
Retail | 3% |
End-of-use | 3% |
Upstream production, from raw materials through garment assembly, accounts for approximately 70% of total emissions, while downstream activities from retail, use, and end-of-use, comprise the remaining 30%.
Fashion consumption, driven by temporary trends and personal preferences, and less by practical concerns like the associated environmental impact, create a challenging context for sustainability practitioners, but innovation is abundant even within this constrained context.
