Sustainability in Fashion: Why Overproduction Is the Real Environmental Problem

Sustainability has become one of the most used — and misused — words in fashion. There are endless
conversations about materials, packaging, and marketing claims. While these topics matter, they often distract from the biggest environmental issue in the industry: overproduction. Fashion produces far more products than the market can absorb. This is not accidental — it’s driven by economies of scale. The more you produce, the cheaper each unit becomes. As a result, brands are incentivized to overproduce and hope demand will follow. When it doesn’t, the consequences are severe: unsold inventory, financial pressure, discounting, waste, and in extreme cases, destruction of products. True sustainability is not about shouting louder with green messages. It starts with listening — listening to the market and not producing what isn’t needed.

Overproduction is one of the biggest challenges in sustainable fashion production. Many fashion brands produce more inventory than the market can absorb, leading to waste, discounting, and environmental harm. Demand-driven production models, including pre-orders, help reduce overproduction by validating demand before manufacturing begins.
