Carbon footprint of a pair of trousers

The median pair of trousers in our catalogue has a carbon footprint of 12.1 kg CO₂e over its whole life, from growing or making the materials to disposal. Half of the 1,563 trousers we have footprinted, from 112 brands, fall between 11.5 and 13.0 kg CO₂e.

Where the footprint of a pair of trousers comes from

In the typical split, production makes up about 51% of the total, followed by use at about 33%. The split shows where a maker's own data changes the result most: replacing published averages for the largest stages with your own figures moves the footprint far more than refining the small ones.

The split is the median share of each stage across the catalogue's trousers, rescaled to add up to 100%. Read cradle to gate versus cradle to grave for what each stage covers.

  • Raw materials 11%
  • Production 51%
  • Packaging 2%
  • Distribution 1%
  • Use 33%
  • End of life 2%

What trousers are made of

The main material is the biggest single choice in a pair of trousers's raw-material footprint. These are the main materials of the trousers in our catalogue, by share of products:

  • Cotton, conventional40%
  • Cotton, organic28%
  • Linen (flax)8%
  • Reused fabric (upcycled sari, scraps, deadstock)4%
  • Wool3%

What lowers it

For each product, our calculator tests common changes and reports the one with the largest saving. For trousers, the changes that come out on top most often are:

  • Run the factory on solar electricity96%
  • Care label: wash cold, line dry4%

Share of trousers for which each change gives the largest saving.

How these figures are made

Each product's footprint is a screening estimate: we read the materials and weight from the product listing, apply emission factors from cited public sources, and follow the ISO 14067 method with every source shown. Without the maker's own energy and supplier data, these are typical values, not measurements of a particular factory.

To footprint your own pair of trousers, start with a free estimate from a product link, or enter your own factory data. See our methodology for the method and sources.

Questions

What is the carbon footprint of a pair of trousers?

Across 1,563 trousers in our catalogue, the median footprint is 12.1 kg CO₂e per item over its whole life, and half fall between 11.5 and 13.0 kg CO₂e. These are screening estimates from product listings; your own product's figure depends on its materials, weight and factory.

Which stage of a pair of trousers's life has the largest footprint?

In the typical split, production is the largest stage at about 51% of the total, followed by use at about 33%.

What is the cradle-to-gate footprint of a pair of trousers?

Counting only raw materials, production, inbound transport and packaging, up to the factory gate, the median is 7.97 kg CO₂e per item. Buyers often ask for this figure for their Scope 3 inventory.

How can a maker lower the footprint of a pair of trousers?

The change our calculator most often finds with the largest saving for trousers is “run the factory on solar electricity”. The best change for your product depends on your own materials and energy.

Can I use these figures for my own pair of trousers?

Use them to see the size of the footprint and where it comes from. For a figure to send a buyer, footprint your own product with your materials, weight and factory energy, so the result describes what you make.
