C02 label of the Kayano™ 31

Empowering movement, redefining sustainability


We’re committed to climate action and bringing the benefits of movement to the world we love to move in.

We've launched the world’s lightest CO₂ emissions shoe* and reduced our direct operations emissions by 29.8% in 2023. Introduced our carbon footprint label as we strive for net-zero emissions by 2050.

*Based on available industry data for life cycle CO₂e emissions as of Sep. 2023.

What is a carbon footprint?


A carbon footprint is the total amount of greenhouse gases generated over a product’s life cycle. We’re committed to reducing our CO₂ emissions throughout the value chain, so we’re being transparent about how we measure and continuously work to reduce our emissions.

We care about our emissions


We measure the carbon emissions at each stage of a product’s life cycle. Below, we’ve explained the carbon footprint of our GEL-NIMBUS® 27 shoe, one of ASICS' pinnacle running shoes.


GEL-NIMBUS 27 shoe

1. Materials

Processes to get finished materials include:

  • Raw material extraction
  • Yarn formation
  • Textile formation
  • Dyeing
  • Finishing

Materials-related carbon emissions for the GEL-NIMBUS® 27 shoe total 4.2kg CO₂e/pair.

2. Manufacturing

Processes for product manufacturing include:

  • Cutting
  • Sewing
  • Gluing
  • Embroidering
  • Assembling

Manufacturing-related carbon emissions for the GEL-NIMBUS® 27 shoe total 4.5kg CO₂e/pair.

3. Transportation

Processes for transporting materials during all stages of the product's life cycle include:

  • Acquiring materials from suppliers
  • Sending products from factories to retail stores
  • Returns
  • Transporting waste to disposal facilities

Transportation-related carbon emissions for the GEL-NIMBUS® 27 shoe total 0.5kg CO₂e/pair.

4. Use

Process-related carbon emissions for the GEL-NIMBUS® 27 shoe total 0.1kg CO₂e/pair.

In partnership with Massachusetts Institute of Technology (MIT), we’ve based our use emissions on the ASICS shoe care guidelines.

5. End of Life

Processes for disposal include:

  • Disposal of used shoes
  • Recycling of shoe packaging materials
  • Disposal of materials used during manufacturing

Disposal-related carbon emissions for the GEL-NIMBUS® 27 shoe total 1.2kg CO₂e/pair*.

*Since ASICS’ products are sold globally, we use industrial or global representative scenarios to calculate disposal-related carbon emissions.
