You asked, we answered: What is cotton’s true greenhouse gas footprint across its lifecycle?

We know you care about sustainable textile choices, especially for our climate. Cotton is a common fiber. It has a detailed environmental path. It covers farming, manufacturing, and use. Below, we show a full GHG assessment. We use trusted research to answer your questions and guide your choices.

🔍 Water Use

Cotton farming uses much water. Water use changes with region and practice.

• Conventional cotton irrigation gives about 17% of total GHG emissions during production.
  (Source: Better Cotton Initiative, 2021)

• Water use shifts by cotton origin. Brazilian BCI cotton uses 11.63 m³/kg. Global averages can reach 49.79 m³/kg.

• Organic cotton may use less water. Yet local differences make one-to-one comparisons hard.
  (Source: Carbonfact, 2024)

Expert tips:

• Use cotton grown with smart irrigation like drip systems.
• Choose Better Cotton Initiative or organic cotton labeled items that show clear water practices.
• Ask brands to offer clear care instructions for washing, as washing uses water too.

🚩 Highlight:

"Irrigation is the second-largest contributor to GHG emissions in cotton production, at 17%."
  — Better Cotton Initiative (2021)

🔍 Carbon Emissions

Cotton’s carbon load changes a lot. Farm inputs and processing energy shape it.

• In some organic cotton areas (like Kyrgyzstan), emissions can be as low as 1.15 kg CO₂e/kg. Elsewhere (like China, USA) conventional cotton shows more than 7 kg CO₂e/kg.
  (Source: Carbonfact, 2024)

• Fertilizer production makes up nearly 47% of cotton’s emissions. Synthetic nitrogen fertilizers add a lot to this share.
  (Source: BCI study, 2021)

• Manufacturing and use (washing and drying) add extra energy emissions. These can go above farming emissions.
  (Source: Cotton Incorporated LCA, 2016)

Expert-backed tips:

• Favor organic or BCI cotton to lower fertilizer use and emissions.
• Support brands that use renewable energy and efficient processes.
• Wash cotton in cold water and hang dry to save energy.

🚩 Highlight:

"Fertilizer production is the largest contributor to GHG emissions in cotton production. It forms 47% of total emissions on average."
  — Better Cotton Initiative (2021)

🔍 Chemical Inputs

Chemical inputs in cotton have many impacts. They affect soil, water, and GHG levels.

• Conventional cotton faces heavy synthetic chemicals that harm soil and water. Organic cotton uses natural inputs. Natural inputs can release some greenhouse gases like nitrous oxide but reduce overall chemical stress.
  (Source: Carbonfact, 2024)

• The Better Cotton Initiative pushes for less synthetic use through integrated pest management and better soil care.

Practical recommendations:

• Choose cotton with credible sustainability labels that limit chemical use.
• Ask brands for full details about chemical inputs.
• Support garments made with fewer treatments.

🚩 Highlight:

"Pesticides on cotton can pollute soil and water, while synthetic fertilizer production fuels GHG emissions."
  — Laurent Vandepaer, Carbonfact (2024)

🔍 Recycling

Recycling cotton helps lower the overall GHG footprint.

• Blending 30% recycled cotton with virgin cotton can reduce GHG emissions by 2.2–8.6%. It can also lower water use up to 24.5% and shrink land use by up to 25.2%.
  (Source: Roy et al., 2023)

• “Take-Back” systems let consumers return cotton garments. This process cuts virgin cotton demand and lessens the environmental load.

Expert tips for consumers and brands:

• Join garment take-back or recycling programs.
• Pick brands that use recycled cotton mixes.
• Encourage more circular practices in textiles.

🚩 Highlight:

"Scaling up a ‘Take-Back’ system could lower GHG emissions by up to 28.7% compared to baseline impacts."
  — Shimul Roy et al., ScienceDirect (2023)

❓ FAQ

Q: Does organic cotton always have a lower carbon footprint than conventional cotton?
A: Not always. Local factors, data gaps, and different farming choices can push organic cotton’s footprint higher sometimes, like in parts of India. Still, organic practices usually cut down on synthetic fertilizers and chemicals. This change lowers both emissions and environmental risks.
