Sustainable Fashion: How Op Shopping Helps the Planet (2026)

Updated: February 23, 2026

The fashion industry has a large environmental impact. Fast fashion, the rapid production of cheap, trendy clothing, has created a culture of disposability, leading to textile waste and resource depletion. Op shopping is a practical antidote to this trend.

Choosing to shop second-hand is an accessible step towards a more sustainable wardrobe. This guide explores the connection between sustainable fashion and op shopping, and how second-hand purchases can help the environment.


The problem with fast fashion

To understand why op shopping is beneficial, it’s important to recognise the harm caused by the fast fashion model.

  • Textile waste: The average Australian throws away 23kg of textiles each year, with most of it ending up in landfill where synthetic fibres can take hundreds of years to break down.
  • Resource consumption: The production of new clothing is resource-intensive. It can take over 2,700 litres of water to produce a new cotton t-shirt, enough for one person to drink for 2.5 years.
  • Chemical pollution: Textile dyeing is a large polluter of water globally, with chemicals often released into waterways, harming ecosystems.
  • Carbon footprint: The fashion industry is responsible for about 10% of global carbon emissions, from manufacturing and processing to shipping garments.

How op shopping creates a sustainable solution

Every time you choose to buy second-hand, you are pushing back against the fast fashion cycle. Here’s how.

1. It promotes a circular economy

The traditional fashion model is linear: “take, make, dispose.” Op shopping is part of a circular economy. It keeps resources in circulation for as long as possible, extracting their value before they are discarded. When you buy from an op shop, you are extending the life of a garment and preventing it from ending up in landfill prematurely.

2. It reduces your carbon and water footprint

By purchasing a pre-loved item, you are saving the resources that would have been used to create a new one. You are saving water, energy, and raw materials. A study from the Waste and Resources Action Programme (WRAP) found that extending the life of clothing by nine months can reduce its carbon, water, and waste footprints by around 20-30% each.

3. It diverts waste from landfill

This is a direct environmental benefit. When you buy (and donate usable items to) op shops, you are participating in a recycling and reuse program. Australia’s op shops collectively divert hundreds of thousands of tonnes of textiles from landfill every year.

4. It sends a message to the industry

Choosing second-hand over new is a form of consumer activism. It tells the fashion industry that you don’t support the disposable, trend-driven model. As more people embrace second-hand, it forces brands to reconsider their unsustainable practices and move towards more ethical production.


Making your wardrobe even more sustainable

  • Think before you buy: Even in an op shop, only buy what you truly love and will wear. Mindless consumption is still consumption.
  • Care for your clothes: Learn basic mending skills to repair small holes or loose buttons. Wash your clothes carefully to extend their life.
  • Dispose of clothes thoughtfully: If a garment is too worn to be donated, look for textile recycling programs in your area. Avoid putting it in the bin if possible.

The connection between sustainable fashion and op shopping is clear. It is a budget-friendly and accessible way for anyone to reduce their environmental impact. Choosing second-hand is a way to save money and support a healthier planet.
