Where the footprint of a piece of underwear comes from

In the typical split, production makes up about 47% of the total, followed by use at about 28%. 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 underwear, rescaled to add up to 100%. Read cradle to gate versus cradle to grave for what each stage covers.

  • Raw materials 11%
  • Production 47%
  • Packaging 8%
  • Distribution 1%
  • Use 28%
  • End of life 4%

What lowers it

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

  • Run the factory on solar electricity99%
  • Care label: wash cold, line dry1%

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