evidence: 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." [...] 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. [...] 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
