Understanding the Carbon Footprint of Denim

Denim, a timeless and versatile fabric, has been a staple in fashion for generations. From classic jeans to trendy jackets, denim garments are a ubiquitous part of our wardrobes. 

‍

Denim production comes with a significant carbon footprint, but as consumers, we can make a difference by making informed choices about the denim they buy.

‍

Where do denim’s emissions come from and how do we shop for sustainable jeans?

The Carbon Footprint of Denim

‍

Quantifying the exact carbon footprint of denim is challenging due to variations in production methods and supply chains. However, research estimates suggest that a single pair of jeans can have a carbon footprint ranging from 33 to 80 kilograms of CO2 equivalent emissions.

‍

Here are the production phases that go into the carbon footprint of denim: 

‍

• Cotton Cultivation: Cotton is the primary raw material used in denim production. Conventional cotton farming relies heavily on pesticides and water, contributing to pollution and resource depletion.
• Fabric Production: After cotton is harvested, it undergoes processing to become denim fabric. The dyeing and finishing processes are energy-intensive and involve the use of chemicals.
• Garment Manufacturing: Cutting, sewing, and assembling denim garments require energy and water. Transportation of materials and finished products adds to the carbon footprint.
• Consumer Use: Frequent washing and drying of denim garments at high temperatures increase their environmental impact.
• End-of-Life: Discarded denim often ends up in landfills, where it decomposes and releases methane, a potent greenhouse gas.

Reducing the Carbon Footprint of Denim

‍

Fortunately, there are ways to reduce the carbon footprint associated with denim production and consumption. First, choose secondhand. Secondhand clothing (especially denim) prevents the need for new denim to be manufactured so choose secondhand as often as possible. 

‍

When you’re buying new, look for a brand that takes responsibility for their carbon footprint by actively lowering and offsetting their emissions. You can use Commons to discover dozens of clothing brands that are Cimate Neutral Certified.

Here’s what to look for in a sustainable denim brand:

‍

• Sustainable Cotton: Opt for denim made from organic or recycled cotton, which requires fewer pesticides and resources.
• Water and Energy Efficiency: Support brands that implement water- and energy-saving technologies in their production processes.
• Dyeing Techniques: Look for denim produced using eco-friendly dyeing techniques that minimize chemical use.
• Ethical Manufacturing: Choose denim from companies committed to ethical labor practices and fair wages for workers.
• Quality Over Quantity: Invest in durable denim garments that last longer, reducing the need for frequent replacements.
• Eco-Friendly Washing: Wash denim less frequently, using cold water and mild detergents to extend its lifespan.
• Upcycling and Recycling: Repurpose old denim items or recycle them through specialized programs to divert them from landfills.
• Secondhand Shopping: Consider buying secondhand denim, which not only reduces demand for new production but also extends the life of existing garments.
• Carbon Offsetting: Support brands that invest in carbon offset programs to mitigate the emissions associated with denim production.

By opting for sustainable materials, supporting eco-conscious brands, and adopting responsible consumption habits, we can reduce the environmental impact of denim and contribute to a more sustainable fashion industry. Remember, every small choice counts in the effort to minimize the carbon footprint of our clothing.
