Environmental Sustainability in the Fashion Industry (2023)

The Environmental Cost of Fashion

The fashion industry represent an important part of our economies, with a value of more than 2.5 trillion $USD and employing over 75 million people worldwide. The sector has seen spectacular growth over the past decades, as clothing production doubled between 2000 and 2014. While people bought 60% more garments in 2014 than in 2000, they only kept the clothes for half as long (McKinsey & Company, 2016).

While the fashion sector is booming, increasing attention has been brought to the impressive range of negative environmental impacts that the industry is responsible for. Fashion production makes up 10% of humanity’s carbon emissions, dries up water sources, and pollutes rivers and streams. What’s more, 85% of all textiles go to the dump each year (UNECE, 2018), and washing some types of clothes sends significant amount of microplastics into the ocean.

The Environmental Footprint of Fast Fashion

  • The equivalent of one garbage truck full of clothes is burned or dumped in a landfill every second (UNEP, 2018)
  • Approximately 60% of all materials used by the fashion industry are made from plastic (UNEP, 2019)
  • 500,000 tons of microfibers are released into the ocean each year from washing clothes — the equivalent of 50 billion plastic bottles (Ellen MacArthur Foundation, 2017)
  • The fashion industry is responsible for 8-10% of humanity’s carbon emissions – more than all international flights and maritime shipping combined (UNEP, 2018). If the fashion sector continues on its current trajectory, that share of the carbon budget could jump to 26% by 2050 (Ellen MacArthur Foundation, 2017)
  • Some 93 billion cubic metres of water – enough to meet the needs of five million people – is used by the fashion industry annually, contributing significantly to water scarcity in some regions (UNCTAD, 2020)
  • Around 20% of industrial wastewater pollution worldwide originates from the fashion industry (WRI, 2017)

Fast fashion also has a human cost: textile workers, primarly women in developing countries, are often paid derisory wages and forced to work long hours in appalling conditions (UNEP, 2018; WRI, 2019). In many places, these conditions create infringements on human rights (Human Rights Watch). Use of chemicals in clothes production also raise serious health concerns, both for the workers in the industry and consumers. Additional impacts on health also arise from the pollution described previously.

The environmental and social cost of the fashion industry forces us to rethink fast fashion, and stresses the need for more sustainable business models and practices. Resources hereunder provide additional information on the environmental impacts of fashion, and potential pathways for change.

Plastic in Textile

After the Second World War, the development of synthetic textiles, such as polyester and nylon, transformed the fashion industry. From only a few thousand tonnes in 1940, global consumption of synthetic fibres rose to more than 60million tonnes in 2018. Since the late 1990s, polyester is the most commonly used fibre in textiles. Today, an estimated 60% of clothing and 70 % of household textiles are made of synthetic fibres.

These plastic-based textiles have a significant impact on the environment and climate throughout their life cycle due to emissions of greenhouse gases and pollutants. The textile sector is a growing contributor to the climate crisis, with about 1% of crude oil production used to produce synthetic fibres. The sector is also an important source of plastic leakage into the environment. Between 200 000 and 500 000 tonnes of microplastics from textiles enter the marine environment each year.

Consideration of the textile sector will thus be important for tackling the ongoing plastic crisis. Plastic pollution is one of the major environmental crises of our times, and efforts from various actors are underway to address it. This includes negotiations towards an international legally-binding agreement on plastic pollution, initiated by the resolution adopted at the UN Environment Assembly in March 2022. Learn more about the plastic pollution crisis, governance processes to address it and the work of Geneva-based organizations on the matter in our Plastics and the Environment series.

International Cooperation on Sustainable Fashion

As fashion value chains are globalized and the industry has a significant impact on the achievement of the UN Sustainable Development Goals (SDGs), international cooperation is important to foster sustainable fashion.

Environmental Sustainability in the Fashion Industry (1)

Impact of the fashion industry on the SDGs (UNECE, 2018)

Launched at the fourth UN Environment Assembly (UNEA-4), the UN Alliance for Sustainable Fashion is seeking to halt the environmentally and socially destructive practices of fashion. The Alliance is improving collaboration among UN agencies by analyzing their efforts in making fashion sustainable, identifying solutions and gaps in their actions, and presenting these findings to governments to trigger policy. Additionally, the Forests for Fashion Initiative, led by UNECE, FAO, and partners, supports innovative solutions in fashion through sustainable forests-based materials. Several other international organizations are working on global efforts to foster more sustainable fashion. Additional information on these initiatives can be found in the links below.

World Cotton Day

Cotton is one of the most common fabrics used for clothes. Producing cotton sustains the livelihood of 28.67 million people and provides benefits to over 100 million families across the globe (WTO, 2020). Recognizing the critical role of cotton for economic development, international trade, and poverty alleviation, the UN General Assembly decided to proclaim World Cotton Day on 7 October (A/RES/75/318).

For its first edition, the day aims to highlight the importance of sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all in the cotton sector. Many actors in Geneva are involved in promoting sustainable production and consumption patterns in the cotton industry (see section below for details).

Cotton production can have consequent impacts on the planet due to the use of pesticides, high water consumption, and the conversion of habitat to agricultural use. Conventional production practices can result in soil erosion and degradation, water contamination, and other forms of pollution. Therefore, supporting sustainable models of cotton production is essential if we are to achieve the SDGs.

The WBCSD support business initiatives for circular economy and sustainable consumption and production, including in the fashion industry.

UN system’s engagement is larger than the Geneva-based organizations presented here. Members of the UN Alliance for Sustainable Fashion also include UNDP, UNEP, UN Global Compact, UNFCCC and UNOPS.

What Can I Do?

While international organizations, governments and businesses work on solutions to shift the fashion industry toward a more sustainable pathway, consumers can also play a role with their daily actions. This section provides resources on the actions individuals can take to support sustainability in their apparel choices.
