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-KAYANO™ 31 shoe, one of ASICS' pinnacle running shoes.

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-KAYANO 31 shoe total 1.19kg CO₂e/pair*.

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