Clothing Carbon Footprint Calculator

Your clothing carbon footprint is the total greenhouse gas emissions (measured in kg CO₂ equivalent) generated throughout the lifecycle of your clothes — from raw material production and manufacturing, through washing and drying, to final disposal. The global fashion industry accounts for around 8–10% of annual global carbon emissions.

Polyester and nylon are the most carbon-intensive fabrics because they are derived from fossil fuels and require significant energy to produce. Conventional cotton is also high due to water usage and pesticide production. Organic cotton, linen, and recycled fibres generally have lower carbon footprints.

Secondhand clothing avoids the production phase entirely, which is responsible for the vast majority of a garment's lifetime emissions. Buying a used item instead of new can reduce its carbon footprint by up to 82%. Platforms like Vinted, eBay, and charity shops are great ways to lower your fashion impact.

Yes — significantly. Around 75–80% of the energy used in a laundry cycle goes to heating the water. Washing at 30°C instead of 60°C can cut the energy used per wash by up to 60%. Cold washes are effective for most everyday clothing and cause far less fabric wear too.

When clothes go to landfill, natural fibres decompose and release methane — a potent greenhouse gas. Donating, reselling, or recycling clothing gives garments a second life and avoids this end-of-life emission. Textile recycling also reduces the demand for virgin fibre production.

In the UK, clothing accounts for roughly 1,000 kg CO₂e per person per year when production, care, and disposal are all included. In the US it can be higher — around 1,200–1,500 kg CO₂e — due to higher consumption rates. Adopting slow fashion habits can reduce this figure by 50% or more.

Fast fashion refers to the rapid production of high-volume, low-cost clothing that mimics current trends and is designed to be worn only a few times before disposal. This model leads to massive overproduction, excessive water use, chemical pollution, and enormous amounts of textile waste — with around 92 million tonnes of clothing sent to landfill globally each year.

Key steps include: buying fewer, higher-quality items; choosing secondhand or vintage clothing; opting for natural or recycled fabrics; washing at lower temperatures; air-drying instead of tumble-drying; and donating or recycling old clothes rather than throwing them away. Even a 50% reduction in new purchases can dramatically cut your fashion footprint.
