You asked: What is the carbon footprint of cotton, especially conventional vs. organic? How do farming practices impact its emissions?
We care about your need for sustainable textiles. We dug into new research. We bring you expert ideas and simple tips on cotton’s carbon footprint.

🔍 Water Use

Cotton needs much water. Its use shifts with region and technique.

• Organic vs. Conventional?
  Organic cotton grows with rain-fed water and natural soil care. This choice can cut energy use and extra emissions. Still, the local climate rules. Some studies show that pumping water adds 17% to cotton’s greenhouse gases (Better Cotton Initiative, 2021).

• Proactive tips:
  • Pick cotton from certified eco-programs like Better Cotton Initiative (BCI) to use water smartly.
  • Choose brands that invest in rain-fed or drip methods.
  • Look for organic cotton grown where the climate makes irrigation easier.

🚩 Highlight: Pumping water adds about 17% of total GHG emissions from cotton.

🔍 Carbon Emissions

Cotton’s carbon output changes with farming style and place.

• Overall footprint:
  Farmers produce about 0.9 kg CO2e for each kg of cotton (2025 ScienceDirect study by Zhuhong Yu & Yi Yang). For fabric, this means nearly 8.3 kg CO2e for 2 square meters of cotton (~150gsm). (CO2E website)

• Key emissions sources:
  • We see fertilizer use and nitrogen release forming about 66% of the emissions.
  • Pumping water and energy in ginning add more.
  • Organic cotton tends to have lower emissions. Some areas, like India, may show different numbers.

• Regional variation:
  In the U.S., China, and Brazil, conventional cotton emits 5.7 – 7.5 kg CO2e per kg because synthetic fertilizers are used. In Kyrgyzstan and Turkey, organic cotton may only emit 1.15 – 3.18 kg CO2e per kg.

• Proactive tips:
  • Use organic or Better Cotton fibers to cut fossil fuel fertilizer emissions.
  • Support brands that power farms and ginning with renewable energy.
  • Ask for more use of manure and compost to improve nitrogen use and lower N₂O.
  • Back research and clear supply chains to fix data blanks.

🚩 Highlight: Nitrogen fertilizer makes up 66% of cotton’s carbon emissions globally. Optimizing nitrogen use and adding manure can reduce emissions by about 37%.

🔍 Chemical Inputs

Conventional cotton farms rely on chemical pesticides and fertilizers. These inputs create greenhouse gases and can harm soil and water.

• Organic cotton does not use synthetic chemicals. This choice cuts indirect emissions and pollution. Still, organic fertilizers can release nitrous oxide as they break down.

• Proactive tips:
  • Favor organic cotton and practices like BCI that lessen chemical inputs.
  • Encourage crop rotation and soil health steps to lower fertilizer needs.
  • Look for full details on chemical use in cotton labels.

🔍 Recycling & Circularity

Cotton fabric recycling cuts the need for new fiber. This choice saves water and lowers carbon emissions.

• Recycle cotton at the pre-use and post-use stages to reuse fibers.

• Proactive tips:
  • Donate or recycle your cotton clothes to stretch their life.
  • Choose brands that mix recycled cotton or design for a circular fate.
  • Learn about how circular fashion can benefit the planet.

❓ FAQ

Q: Does organic cotton always have a lower carbon footprint than conventional cotton?
A: Yes, usually it does. Organic farming cuts down on synthetic fertilizers and pesticides that create many emissions. Yet, factors like yield, water use, and local differences mean that some organic cotton (for example, in India) may show higher footprints. Clear data and more studies are needed.
