What You'll Learn
Water pollution
The textile industry's water pollution is caused by the release of untreated or partially treated wastewater into the environment. This wastewater contains various contaminants, including dyes, chemicals, heavy metals, pesticides, fertilisers, and microplastics. These pollutants can seep into nearby water sources, contaminating streams, rivers, and groundwater. In some cases, this contaminated water is used for irrigation, leading to the presence of carcinogenic chemicals in food sources.
The issue of water pollution in the textile industry is particularly prevalent in developing countries, such as those in Asia, where a large portion of textile production is based. For example, China's rapid industrialization and lax environmental regulations have severely impacted its water quality, with textile wastewater contributing significantly to this deterioration. Similarly, in Bangladesh, the garment industry's excessive water usage depletes groundwater resources and transports harmful contaminants to nearby water sources.
The rise of fast fashion has exacerbated the problem of water pollution in the textile industry. Fast fashion encourages mass production, low prices, and high sales volumes, leading to increased water consumption and pollution levels. The culture of constantly updating wardrobes has resulted in higher water consumption and pollution, with consumers purchasing 60% more clothing than 15 years ago. Additionally, the production of synthetic fabrics, which require significant oil usage, further contributes to water pollution by releasing pollutants such as lead, arsenic, and benzene into water sources.
To address water pollution in the textile industry, stricter regulations and enforcement of wastewater treatment standards are necessary. Initiatives such as the EU Ecolabel, which promotes products with fewer harmful substances and reduced water pollution, are a step towards incentivizing more sustainable practices. Additionally, new technologies for dyeing textiles that reduce water usage and chemical discharge are essential for mitigating the industry's water pollution.

Carbon emissions
The textile industry is a major contributor to global warming, with annual carbon dioxide (CO2) emissions of approximately 4 billion tonnes, accounting for around 10% of global greenhouse gas emissions. The industry's complex supply chains and energy-intensive production processes result in a significant carbon footprint. The manufacturing phase, in particular, requires a significant amount of heat and electricity, contributing to the sector's carbon emissions.
The type of fibre used in textile production also impacts carbon emissions. According to the Pulse of the Fashion Industry report, leather, silk, and wool have the highest emissions by kg of material, while polypropylene and acrylic fibres have the lowest. Synthetic fibres, while having lower carbon emissions, are made from non-renewable resources and contribute to microplastic pollution.
The production of raw materials is another major source of emissions in the textile industry. Growing conventional cotton, for example, requires large quantities of water and pesticides, contributing to its carbon footprint. The upstream stages of yarn preparation and dyeing or bleaching alone account for 28% and 36% of the sector's total carbon-equivalent emissions, respectively, due to their energy intensity.
To reduce carbon emissions, the fashion industry needs to move towards more aggressive decarbonization trajectories. This includes adopting new technologies such as digital product development systems, investing in pollution prevention technology, and implementing government policies for manufacturing hubs to remove impediments to decarbonization.
There have been efforts to address the carbon emissions of the textile industry. The United Nations Framework Convention on Climate Change (UNFCCC) Fashion Industry Charter for Climate Action, launched in 2018, aims for a 30% reduction in greenhouse gas emissions by 2030 and net-zero emissions by 2050. Additionally, the EU has introduced measures such as the EU Ecolabel and extended producer responsibility schemes to encourage more sustainable practices and reduce the environmental impact of the textile industry.

Energy use
The textile industry is one of the most polluting industries in the world, and energy use is a significant contributor to this. The industry's energy-intensive production methods generate 8–10% of global carbon emissions, surpassing the emissions from the aviation and shipping industries combined.
The fashion industry is the second-largest consumer industry of water, requiring about 700 gallons to produce one cotton shirt and 2,000 gallons of water to produce a pair of jeans. This water consumption is closely linked to energy use, as water needs to be pumped, heated, and treated, requiring significant energy expenditure.
The transformation of raw materials into garments in factories consumes enormous amounts of energy. The energy-intensive processes based on fossil fuel energy have a significant environmental impact. For example, the production of plastic fibres into textiles requires large amounts of petroleum and releases volatile particulate matter and acids. Additionally, the use of synthetic fibres like polyester, nylon, and acrylic contributes to the industry's carbon footprint, as these materials take hundreds of years to biodegrade.
The geographical spread of the supply chain also contributes to the industry's energy consumption. The transportation of fabrics and garments from production points, often located in developing countries, requires significant energy expenditure. Furthermore, the logistics of distributing goods globally at various production stages add to the carbon footprint.
To address these issues, there have been calls for the development of new business models for clothing rental and the implementation of digital product development systems. Innovations in recycling and end-of-life processes, as well as investments in renewable energy sources, are also crucial in reducing the industry's energy consumption and environmental impact.

Chemical use
The use of chemicals in the textile industry is a significant contributor to environmental pollution. The industry is responsible for about 20% of global clean water pollution from dyeing and finishing products. This includes the use of dyes and finishing agents, which often leak into water sources, contaminating them with toxic chemicals. The production of leather, for example, involves the use of mineral salts, formaldehyde, coal-tar derivatives, and various oils and dyes, which contaminate water sources as they are not biodegradable.
Textile manufacturing also releases hazardous waste, including chemicals such as formaldehyde, chlorine, and heavy metals, into the surrounding land and water bodies. These toxic chemicals can have devastating impacts on the health of local people, animals, and ecosystems. The use of pesticides and fertilizers in cotton cultivation, the most widely used natural fibre, also contributes to groundwater contamination.
The complex supply chains and energy-intensive production methods of the textile industry further exacerbate the problem. With production spread across multiple countries, the transportation of fabrics and garments adds to the industry's carbon footprint. The energy-intensive processes, often based on fossil fuels, deplete natural resources and contribute to global warming.
The massive use of various chemicals in textile production is a significant environmental concern. It is estimated that almost 2000 different types of chemicals are used in the industry. These chemicals, if not properly managed and decomposed, can leak into the environment, causing further ecological damage.
To address these issues, there is a growing focus on sustainable practices in the textile industry. This includes the use of organic raw materials, such as organic cotton, which reduces the need for pesticides and fertilizers. Environmentally friendly methods of cultivation and manufacturing are being explored, and there is a push for stricter control and legislation to prevent chemicals from ending up in nature.

Textile waste
The textile industry is responsible for a significant amount of waste, with surveys showing that nearly 5% of all landfill space is consumed by textile waste. In 2018, 17 million tons of textile waste ended up in landfills in the US, according to the Environmental Protection Agency. This is equivalent to 11.3 million tons of textile waste in America annually, or 85% of all textiles. The average US consumer throws away approximately 81.5 pounds of clothing each year, which is about 37 kilograms. This is a dramatic increase from just 15 years ago, when items were worn 35% more before being discarded.
The rise of fast fashion has been a major contributor to the increase in textile waste. Fast fashion is driven by mass production, low prices, and high sales volumes, which encourages consumers to buy more clothing and contribute to the ever-growing waste problem. The production of clothing also consumes a large amount of water, with a single cotton shirt requiring 2,700 litres of water to produce, according to some sources. This has led to the textile sector being the third largest source of water degradation and land use in 2020.
To address the impact of textile waste on the environment, the EU has proposed measures to reduce textile production and consumption, increase the life cycle and recycling of textiles, and promote sustainable practices. These include the EU Ecolabel, which highlights products that include fewer harmful substances and cause less water and air pollution.
Additionally, companies like Patagonia and H&M have started offering recycling services and second-hand platforms to extend the life of their products and keep them out of landfills.
