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. Here's how we calculate the carbon footprint of the GEL-KAYANO® 30, one of ASICS' pinnacle running shoes.
1. Materials
Processes to get finished materials include:
- Raw material extraction
- Yarn formation
- Textile formation
- Dyeing
- Finishing
Materials-related carbon emissions for the GEL-KAYANO® 30 shoe total 4.7kg CO2e/pair.
2. Manufacturing
Processes for product manufacturing include:
- Cutting
- Sewing
- Gluing
- Embroidering
- Assembling
Manufacturing-related carbon emissions for the GEL-KAYANO® 30 shoe total 4.7kg 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-KAYANO® 30 shoe total 0.4kg CO2e/pair.
4. Use
Process-related carbon emissions for the GEL-KAYANO® 30 shoe total 0.03kg 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-KAYANO® 30 shoe total 0.8kg CO2e/pair*.
*Since ASICS’ products are sold globally, we use industrial or global representative scenarios to calculate disposal-related carbon emissions.
The GEL-KAYANO® 30 shoe’s carbon footprint is 14% lower than the industry average.*
*Assessed using consistent methodology across ASICS’ carbon footprint methodology and the most comprehensive reporting available for industry average running shoes, conducted by MIT (report). Learn more about our calculation methodology (here).
