The ethics of cotton production

Cotton makes up around a quarter of all fibres, and after polyester is the most widely used fabric in our clothing.

Cotton is the main source of income for around a billion people worldwide, including 100 million farmers. In fact, according to WWF, the industry “employs almost 7% of all labour in developing countries.”

However, the industry is also associated with many ethical issues – from forced labour to use of genetically modified seeds. It is also amongst the world’s thirstiest and most pesticide-intensive crops.

What is the water footprint of cotton?

Cotton is an incredibly water-intensive fabric. Just one cotton t-shirt will require around 2,500 litres of water to produce (depending on where it was grown). 

That’s the same amount one person drinks in two and a half years.

As a crop, cotton usually needs to be irrigated in addition to rainwater, meaning that water is drawn from rivers, lakes and other sources, contributing to water scarcity and depletion.

In India, the water required to grow a year’s worth of cotton for export could supply over half of the population with 100 litres of water a day for an entire year. Meanwhile, over 90 million people - over 6% of India's population - don’t have access to safe water.

By comparison, hemp uses around 80% less water per kg than cotton.

The world’s dirtiest crop?

Cotton is said to cover 2.4% of the world’s cultivated land and yet uses 4.7% of the world’s pesticides and 10% of the world’s insecticides, more than any other major crop. This fact led the Environmental Justice Foundation to declare cotton the world’s ‘dirtiest’ agricultural commodity.

Chemical pesticides are a biodiversity problem and major driver of plummeting bird and bee numbers, as well as collapsing soil health. The majority of chemical pesticides are derived from fossil fuels, which therefore has climate change implications.

Genetically modified cotton

According to the International Service for the Acquisition of Agri-Biotech Applications (ISAAA), a non-profit pro-biotech organisation, genetically modified (GM) cotton accounted for around 80% of cotton grown in 2019.

Campaigners argue that GM cotton poses unnecessarily risks, about which little is understood. GM plants are designed to be more dominant than other kinds, meaning that when crossbreeding takes place, GM varieties can spread and wipe out native varieties. GM seeds are also often designed to be used with certain kinds of pesticides, locking farmers into toxic chemical use.

Farmers are also unable to save their seeds and can get locked into a cycle of debt, unable to cover the costs of the more expensive  seeds and chemicals.

When rating companies for our shopping guides, if a company does not source 100% organic cotton or 100% Fairtrade cotton it loses half a mark under Ethical Consumer’s Pollution & Toxics and Controversial Technologies categories.

Is there any ethical cotton available?

There are several international schemes which seek to certify or enable ethical cotton which hasn't used forced labour, or is organic or fair trade. We highlight some of these schemes below.

Responsible Sourcing Network

The Responsible Sourcing Network (a project of USA organisation As You Sow) asks brands to avoid using Turkmen cotton by signing up to its ‘Cotton Pledge’.

By signing up to the pledge brands are then expected to communicate their policy to suppliers; use traceability documents for all cotton products and textiles; identify the location of strategic mills; engage with the Turkmen Government; and consider joining RSN’s Economic Leverage Working Group on Turkmen Cotton.

Five companies in our clothing guide had signed the Responsible Sourcing Network’s Turkmen Cotton Pledge which commits them to not knowingly use cotton from Turkmenistan:

• Amazon
• Gap
• H&M / COS / & Other Stories / Monki
• M&S
• Primark

These companies did not lose a mark under Workers’ Rights. Other companies, like New Look, which had not signed the Cotton Pledge but made detailed public statements about not sourcing from Turkmenistan, also did not lose a mark here.

Ethical Consumer and Responsible Sourcing Network previously also expected not to source from Uzbekistan, where state-sanctioned forced labour was rife in cotton production. But in 2021, NGOs found no forced labour in the country’s cotton industry and stated that after many years the issue had been resolved.

Sustainable cotton sourcing

A growing number of companies use only ‘sustainable cotton’, which they usually define as organic, recycled and Better Cotton, and/or Fairtrade. These include:

• H&M (and its brands COS, Monki, and & Other Stories)
• M&S
• Nobody’s Child
• Patagonia

Many other brands have made pledges to source 100% ‘sustainable cotton’ between now and 2025, including Amazon, ASOS, Bershka, Debenhams, Gap, H&M, Levi’s, Marks and Spencer, Nasty Gal, Next, Sainsbury's, Tesco’s F&F, Warehouse, White Stuff, Uniqlo and Zara. Some others have pledges for 2030.

Ethical Consumer considers the most sustainable cotton to be organic or recycled. This means you won’t be supporting GM cotton (which is allowed under initiatives such as Better Cotton, which lots of brands favour).

Better Cotton Initiative

The Better Cotton Initiative is a multi-stakeholder initiative which was set up in 2005 to reduce the water and pesticides used to grow cotton. The initiative also has criteria on ‘decent work’ which are based on the labour standards of the International Labour Organisation, the UN specialised agency on work and employment. It has 300 retailer members and is supported by civil society organisations such as WWF and Pesticides Action Network.

It involves monitoring and assessment by third parties to make sure that the standards are adhered to.
Farmers benefit from increased profits and health benefits from the reduced use of costly pesticides (which can account for up to 60% of farming costs). But unlike programmes such as Fairtrade, there is no formal product labelling system for consumers and no premium paid to the farmers.

There are also no criteria to prohibit the use of GM cotton.

The programme has come under fire in recent years for failing to address forced labour in the Uyghur region of China. In March 2020, Better Cotton suspended activities in the region over major human rights concerns. But a year later, after backlash in China, it deleted all public statements and references to exiting the region.

The Coalition to End Uyghur Forced Labour condemned the decision, stating: “By continuing to operate in China without being clear on its zero tolerance for forced labour and its rationale for exiting the Uyghur Region, BCI is allowing itself to be used by the Chinese government to claim that business can go on as usual and to deny the ongoing crimes against humanity, including widespread and systematic forced labour, in the Uyghur Region.”

In the 2020-21 cotton season, 2.2 million farmers grew under Better Cotton. They produced 4.7 million metric tonnes, amounting to around 20% of global production.

Certified cotton on the high street

There is a general lack of Fairtrade, organic and recycled clothes on the high street, but the situation is slowly improving.

Patagonia only uses organic cotton. H&M, Asos, and New Look offer organic cotton clothes in ranges of varying degrees of variety.
