Carbon footprint of PU synthetic leather
Our calculator counts 11.7 kg CO₂e for every kilogram of PU synthetic leather in a product made in India. Below is where that figure comes from, how sure we are of it, and what it adds up to in finished products: 659 products in our catalogue, from 38 brands, contain PU synthetic leather.
Where the figure comes from
The factor is PU synthetic leather (per kg), for GLO. Source: Derived from PU synthetic leather 7 kg CO2e/m² at ~0.6 kg/m².
Status: Contested. Published, but sources disagree or the scope is non-standard; includes every screening proxy. Sensitivity analysis is mandatory.
An emission factor is the greenhouse gas emitted per unit of something, here per kilogram of material up to the point it is ready to be made into a product. Read emission factors explained, or see every factor and source in our methodology.
From material to product
A kilogram of PU synthetic leather is only the start. Making it into yarn, fabric, a sheet or a part, dyeing or finishing it, making the product, and packing and moving it all add emissions. So does the use and disposal of the product, for a whole-life figure.
That is why products with the same material can have quite different footprints: the weight, the factory's energy and the processes matter as much as the material itself.
Products made only of PU synthetic leather
Median whole-life footprint per item of catalogue products whose only listed material is PU synthetic leather, by kind of product. Compare within a row, not across rows: different products do different jobs.
Screening estimates from product listings with the ISO 14067 method and cited emission factors, not measurements of a particular factory.
Use your own data
If your mill or supplier can give you a footprint for the PU synthetic leather you buy, use it: it describes your material rather than a typical one, and raises your primary data share. Then footprint your product with your own data, or start from a product link.
Questions
What is the carbon footprint of PU synthetic leather per kg?
Our calculator uses 11.7 kg CO₂e per kg of PU synthetic leather for products made in India, taken from Derived from PU synthetic leather 7 kg CO2e/m² at ~0.6 kg/m². Other studies give other values, because farming or production methods, energy and system boundaries differ.
Does the material's footprint equal the product's footprint?
No. The material is one part. Spinning, weaving or forming, dyeing, making the product, packaging, transport, use and disposal are added on top, and offcuts mean more material is bought than ends up in the product.
What is the footprint of a product made only of PU synthetic leather?
In our catalogue, the median crossbody made only of PU synthetic leather comes to 6.59 kg CO₂e per item over its whole life, across 63 products. These are screening estimates from product listings.
How reliable is this emission factor?
Its status in our library is “Contested”: Published, but sources disagree or the scope is non-standard; includes every screening proxy. Sensitivity analysis is mandatory. A supplier's own data for the material, such as a mill's footprint, replaces it when available.
