It takes around 7,500 litres of water to make a single pair of jeans, equivalent to the amount of water the average person drinks over a period of seven years. That’s just one of the many startling facts to emerge from recent environmental research, which show that the cost of staying fashionable is a lot more than just the price tag.
When we think of industries that are having a harmful effect on the environment, manufacturing, energy, transport and even food production might come to mind. But the fashion industry is widely believed to be the second most polluting industry in the world.
According to UNCTAD, some 93 billion cubic metres of water - enough to meet the needs of five million people - is used by the fashion industry annually, and around half a million tons of microfibre, which is the equivalent of 3 million barrels of oil, is now being dumped into the ocean every year.
As for carbon emissions, the industry is responsible for more than all international flights and maritime shipping combined.
The dominant business model in the sector is that of “fast fashion”, whereby consumers are offered constantly changing collections at low prices, and encouraged to frequently buy and discard clothes. Many experts, including the UN, believe the trend is responsible for a plethora of negative social, economic and environmental impacts and, with clothing production doubling between 2000 and 2014, it is crucially important to ensure that clothes are produced as ethically and sustainably as possible.
Innovating for sustainability
Despite the grim statistics, producers and consumers of fashion are increasingly waking up to the idea that the industry needs to change. A number of companies, including large volume retailers, are integrating sustainability principles into their business strategies. Examples include the global clothing chain H&M, which has a garment collection scheme; jeans manufacturer Guess, which is involved in a wardrobe recycling programme; and outdoor clothing company Patagonia, which produces jackets using polyester from recycled bottles.
Smaller companies are also helping change the environmental landscape of fashion and building sustainability into their whole business model.
Among them are the Swiss firm Freitag, which upcycles truck tarpaulins, seat belts and seat belts to make bags and backpacks; Indosole, which makes shoes from discarded tyres; and Novel Supply, a Canadian clothing business, which has a “take-back scheme,” whereby customers can return their clothes when they are no longer wearable, so that the company can reuse and recycle them.
The founder of Novel Supply, Kaya Dorey,, won a Young Champions of the Earth award, the UN’s highest environmental honour, in recognition of her attempts to create a production model that involves using environmentally-friendly materials, and finding solutions for waste created during the manufacturing process.
In this video she explains how every element of her company’s production process is geared towards minimising waste and damage to the environment.
The UN’s role in cleaning up the fashion industry
If we carry on with a business-as-usual approach, the greenhouse gas emissions from the industry are expected to rise by almost 50% by 2030 Elisa Tonda, Head of the Consumption and Production Unit at UN Environment
In a bid to halt the fashion industry’s environmentally and socially destructive practices, and harness the catwalk as a driver to improve the world’s ecosystems, 10 different United Nations organizations established the UN Alliance for Sustainable Fashion, launched during the 2019 UN Environment Assembly, which took place in Nairobi in March.
Elisa Tonda, Head of the Consumption and Production Unit at the UN Environment Programme (UNEP), one of the 10 UN bodies involved in the Alliance, explained the urgency behind its formation: “The global production of clothing and footwear generates 8% of the world’s greenhouse gas emissions and, with manufacturing concentrated in Asia, the industry is mainly reliant on hard coal and natural gas to generate electricity and heat. If we carry on with a business-as-usual approach, the greenhouse gas emissions from the industry are expected to rise by almost 50% by 2030.”
The power of influencers
British artist and environmental activist Elle L was one of the speakers at the launch, and she told UN News that she agrees that fast-fashion was the biggest obstacle to sustainability: “there’s a real pressure to buy, and there are no brake pads to slow over-production and over-consumption. We need better labelling, so that people know what they’re buying; a tax or a ban on synthetic fibres which are causing serious environmental damage and contributing to a micro-plastics crisis; and a shift in mindset regarding over-production and over-consumption.”
Increasingly, and particularly over the last 10 years, it is social media ‘influencers’ like Lucia Musau, an award-winning fashion and lifestyle blogger based in Kenya, who are effectively spreading the kind of messages that can help highlight the negative consequences of fast fashion.
UN News spoke to Lucia whilst she was taking part in talks about sustainable fashion at the UN Environment Assembly, and she agreed that, over time, she has become a voice to be reckoned with, advising people on trends and influencing what they buy:
“As global citizens we have a big role to play. We’re becoming more conscious about the fashion we consume, and gone are the days when you could just buy something because it’s trendy. If a Kenyan designer wants me to promote them, I want to know exactly how they produce the clothes,” said the blogger, who’s also supporting the new UN alliance.
As consumers become more aware, the industry will have no choice but to adapt to their needs,” she said.
Less is more
Despite the moves being made by some retailers to make the industry less harmful to the environment, it can be argued that, ultimately, the only way to really make fashion sustainable is to end the throwaway culture.
Not only is the average person buying 60 per cent more items of clothing than they did 15 years ago but, according to the McKinsey 2019 State of Fashion report, they are only keeping them as half as long as they used to.
UNEP says that promoting a change in consumption modes, through actions such as taking better care of clothes, recycling and “take-back” programs, can make a major impact, and that simply doubling the time that we use each item of clothing could halve the fashion industry’s greenhouse gas emissions.
However, for this to happen, both retailers and consumers will have to reject the “take, make and dispose” model and agree that, for the sake of the planet, when it comes to fashion, less is more.
Environmental impact of fashion industry
- 2,000 gallons of water needed to make one pair of jeans
- 93 billion cubic metres of water, enough for 5 million people to survive, is used by the fashion industry every year
- Fashion industry produces 20 per cent of global wastewater
- Clothing and footwear production is responsible for 8% of global greenhouse gas emissions
- Every second, the equivalent of one garbage truck of textiles is landfilled or burned
- Clothing production doubled between 2000 and 2014
