What is a carbon footprint?
A carbon footprint is the total amount of greenhouse gas 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™ 30, one of ASICS' pinnacle running shoes.
Learn more about our calculation methodology here .
1. Materials
Processes to acquire finished materials include:
- Raw material extraction
- Yarn formation
- Textile formation
- Dyeing
- Finishing
Materials-related carbon emissions for the GEL-KAYANO™ 30 shoe total 4.7 kg CO 2 e/pair.
2. Manufacturing
Processes for product manufacturing include:
- Cutting
- Sewing
- Gluing
- Embroidering
- Assembling
Manufacturing-related carbon emissions for the GEL-KAYANO™ 30 shoe total 4.7 kg CO 2 e/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 shops
- Returns
- Transporting waste to disposal facilities
Transportation-related carbon emissions for the GEL-KAYANO™ 30 shoe total 0.4 kg CO 2 e/pair.
4. Use
Process-related carbon emissions for the GEL-KAYANO™ 30 shoe total 0.03 kg CO 2 e/pair.
In partnership with the 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 manufacture
Disposal-related carbon emissions for the GEL-KAYANO™ 30 shoe total 0.8 kg CO 2 e/pair*.
* As ASICS’ products are sold globally, we use industrial or global representative scenarios to calculate disposal-related carbon emissions.
Total
10.7 kg CO2/pair
The GEL-KAYANO™ 30 shoe’s carbon footprint is 14% lower than the industry average.*
