You asked, we answered: What is the environmental impact of cotton imports and how does it affect our planet?

We know you care about sustainable choices when you wear garments or use textiles daily. Cotton comes from nature, yet its import brings hidden environmental costs. Data from trusted experts and organizations shows these impacts. Read on to learn more and get practical tips.

🔍 Water Use

Cotton farming uses large amounts of water. This fact concerns many regions that are already short of water.

• The United Nations Environment Programme and WWF say that one cotton t-shirt needs about 2,700 liters (713 gallons) of water. This amount equals 2.5 years’ worth of drinking water for one person.

• In Pakistan, roughly 97% of the water in the Indus River goes to crops such as cotton. Inefficient irrigation worsens the problem. WWF notes that Better Cotton Initiative farmers cut water use by 39% over many fields.

• The Aral Sea disaster shows water stress from cotton farming. Once the fourth-largest lake, the Aral Sea lost 90% of its water because of irrigation practices, which led to ecological and health issues.

Tips to reduce cotton water impact:

• Pick products that have a Better Cotton certification to help water-efficient farming.
• Support companies that recycle water and use smart irrigation methods.
• Cut back on fast fashion to lessen the water footprint from many purchases.
• Try natural fibers that need less water, like hemp or flax.
• Wash cotton clothes less often and hang them to dry to save water.

🔍 Carbon Emissions

Cotton imports add to the world’s carbon emissions. This happens during farming, processing, transport, and even during a garment’s life.

• Studies show that greenhouse gas emissions vary with location. For example, emissions from using cotton depend on the energy grid of the area. [Nature Reviews Earth & Environment, 2023]

• Alternatives like synthetic fibers may produce high fossil fuel emissions. Cotton, however, causes emissions through pesticides, fertilizers, and irrigation.

• Other natural fibers like wool, hemp, and flax may offer lower emissions if grown with care.

Expert insight:
Dr. Gregory Peters from the 2023 Nature Reviews Earth & Environment study explains that improved irrigation and fewer pesticides can cut cotton’s emissions.

Tips to minimize carbon impact:

• Buy fewer garments of higher quality so they last longer.
• Support brands that rely on renewable energy in textile production.
• Choose organic or Better Cotton-certified fabrics with fewer chemicals.
• Air-dry clothes and skip the iron to save energy.
• Buy cotton items made nearby to lower transport emissions.

🔍 Chemical Inputs

Cotton farming uses many pesticides and fertilizers.

• Globally, cotton uses 200,000 tons of pesticides and 8 million tons of fertilizer each year. This represents 16% of pesticide use and 4% of fertilizer use worldwide. [UNEP via ISC Blog]

• Pesticides affect the soil, water, wildlife downstream, and worker safety in many farming areas.

• The Better Cotton Initiative works to reduce harmful practices and lower chemical runoff.

Tips to reduce chemical impact:

• Choose organic or Better Cotton products to lower chemical use.
• Ask for more supply chain details on pesticide and fertilizer use.
• Repurpose or recycle cotton clothes to cut new chemical use.
• Favor clothes with low-impact dyes and sustainable finishing.
• Learn about brands that work to reduce agrochemical impacts.

🔍 Recycling

Recycling textiles lessens cotton’s environmental footprint.

• Experts in Nature Reviews stress that recycling and long garment life can reduce water, carbon, and chemical impacts.

• Mechanical and chemical recycling help lessen the need for new cotton and its effects.

Tips to embrace sustainable cotton recycling:

• Donate or sell old cotton garments so they keep being used.
• Look for products that include recycled cotton.
• Support brands that invest in textile-to-textile recycling methods.
• When possible, recycle cotton instead of burning or discarding it.
• Share the recycling benefits with friends and family.

❓ FAQ

Q: Does imported cotton have a larger environmental footprint than locally produced cotton?
A: Yes, it does. Imported cotton adds more carbon from transport. Cotton from water-stressed areas may also use more water and chemicals. Supporting sustainable certifications like Better Cotton can help reduce these impacts, no matter where the cotton comes from. [Nature Reviews Earth & Environment, WWF]
