Why buying second-hand actually has a massive environmental impact

It is easy to think that buying one second-hand t-shirt instead of a new one doesn't make a big difference. But when millions of people make that same choice, it triggers a massive shift in global emissions, water conservation, and waste reduction.

If you have ever wondered why Sellpy is so passionate about the circular economy, here is a look at the actual environmental impact of shopping second-hand.

The water crisis in your wardrobe

Producing new textiles requires a staggering amount of water. According to the UN Environment Programme (UNEP), growing the cotton and dyeing the fabric for just one new pair of jeans takes roughly 7,500 liters of water. That is the equivalent of the water an average person drinks over seven years.

• The second-hand impact: When you buy a pair of vintage jeans on Sellpy, no new cotton needs to be grown, and no new dyes pollute local waterways. You are essentially saving thousands of liters of water with a single click.

Cutting carbon emissions (and being honest about ours)

The fashion industry is responsible for nearly 10% of global carbon emissions—more than all international flights and maritime shipping combined, according to UN Climate Change data. These emissions come from factories, synthetic material production (like polyester, which is derived from oil), and global shipping.

• The second-hand impact: Let's be transparent: second-hand shopping is not a zero-emission magic trick. Shipping your bag to our warehouse, running our facilities, and shipping the final item to its new owner all generate carbon emissions. However, these logistical footprint costs are only a fraction of the large amounts of energy required to manufacture a brand-new garment from scratch. By choosing pre-loved, you are bypassing the heaviest industrial emissions and choosing the vastly better alternative.

Keeping clothes out of landfills

Right now, the world generates more than 92 million tonnes of textile waste annually. According to the UN and the Ellen MacArthur Foundation, that is the equivalent of a garbage truck full of clothing being dumped into a landfill or burned every single second. In Europe alone, the European Commission reports that 5.8 million tonnes of textiles are discarded every year.

• The second-hand impact: By selling your unwanted clothes and buying pre-loved items, you directly divert usable goods from landfills. You are extending the garment's lifecycle and proving that clothes have value long after their first season.
