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 considered by the UN Conference on Trade and Development (UNCTAD), 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. 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.”
Environmental impact of fashion industry
1) 2,000 gallons of water needed to make one pair of jeans
2) 93 billion cubic metres of water, enough for 5 million people to survive, is used by the fashion industry every year
3) Fashion industry produces 20 per cent of global wastewater
4) Clothing and footwear production is responsible for 8% of global greenhouse gas emissions
5) Every second, the equivalent of one garbage truck of textiles is landfilled or burned
6) Clothing production doubled between 2000 and 2014
