Longest lasting jeans: Why you need to wear your jeans for nine months longer to offset their carbon footprint
Out edit of the longest lasting jeans is brimming with denim you'll love for a lifetime.

By Charlie Bell
We all know fast fashion is the enemy when it comes to the environment and our best jeans can be one of the main culprits. Why is the carbon footprint of jeans so bad? From online shopping to quick-changing trends, we are buying more than ever before, choosing a quick high-street hit over the longest lasting jeans. Worse, we're disposing of it quicker, too.
According to estimates from the UN, the fashion industry contributes to around 10% of global greenhouse gas emissions and nearly 20% of wastewater. Factors such as how clothing is transported, produced and then disposed of all contribute to the devastating impact on the environment.
For example, a single pair of jeans requires 1kg of cotton, and producing that uses around 10,000 litres of water. That’s enough drinking water for one person over an entire decade – and that’s just one pair!
From skinny jeans to mom jeans, think about how many pairs the average person owns. Frightening, eh? That’s a lot of wastewater – and much of this wastewater is full of chemicals and dyes that impact our rivers and oceans as well. This is all before our jeans even enter our wardrobes.
How damaging to the environment is a pair of jeans?
Despite making some of the longest lasting jeans on the market, Levi Strauss estimates that a pair of their signature 501 jeans will produce the equivalent of 33.4kg of carbon dioxide equivalent across it's entire lifespan. That's about the same as driving 69 miles in the average US car. These emissions are from a combination of production, packaging, transport and consumer use – mainly from washing.
This is where we come in. If we washed our jeans after every 10 wears, rather than every two, it could reduce water usage and climate-change impact by up to 80% - a big improvement in the carbon footprint of jeans. UK consumers use more hot water than American or Chinese consumers, and if we washed our jeans in cold water instead of warm, it would reduce climate impact by 21%. How we dry our clothes is important, too. Line drying is a lot more planet-friendly than using a tumble dryer.
“You don’t need to wash clothes as often as you might think. You can hang your clothes out to air, for example, rather than washing them after each wear. Reducing the amount of washing that you need to do is the best way of making sure that microplastics don’t get into the water system,” says Fee Gilfeather, Oxfam’s sustainable-fashion expert.
How else can we help offset the carbon footprint?
As well as washing less, there are other small things things we can do to help offset the carbon footprint of jeans and other clothes. Think investing in higher-quality, long lasting jeans, holding onto them for longer and wearing more often.
If we continued to wear our clothes for just nine months longer, it could reduce their environmental impact by 22%, according to a report by recycling charity Waste and Resources Action Programme (WRAP).
Hands up if you have clothes in your wardrobe that don't fit you any more? Or have never even been worn in the first place? You're not alone. Research by Oxfam found that the average adult currently owns at least two items that remain unworn.
Thanks to our thirst for new trends, the lifespan of our clothes has been significantly shortened, but holding on to our clothes longer will help the planet. As will resisting the urge to buy anything new. And seeing as jeans are a fashion mainstay, it’s definitely worth investing in a long-lasting pair instead of 'throw-away' cheap jeans.
“Buying clothes that are made to last is better for the planet, but you can also extend the life of your clothes by repairing them. Consider stitching on buttons that have fallen off or patching up holes. That way, you reduce waste and reduce the need to buy new clothes, all of which is a drain on the planet’s resources,” adds Fee.
Around 350,000 tonnes of used clothing ends up in landfill in the UK every year and many of these items could have been recycled or upcycled.
When you are ready to get rid of clothing, think first about how you can give it another lease of life. Donate old items to a charity shop, sell them at a car-boot sale or have a clothes swap with friends.
