CO2 reduction

Mazda promotes the efficient use of energy while aiming to reduce CO2 emissions in the area of logistics.

CO2 Emissions Reduced by 35.5% Compared with FY March 1991 Levels

Mazda is working with logistics companies, dealerships, and other automakers throughout Japan to reduce CO2 emissions during product shipment.
Since FY March 2011, Mazda has expanded tracking capability for CO2 emissions during import/export of finished vehicles and parts overseas.

FY March 2014 Results

Total domestic transportation volume (including the purchase and supply of materials, parts and finished vehicles) was 480 million ton-kilometer. This represents a 35.5% reduction in transportation CO2 emissions per ton-kilometer compared with FY March 1991 levels, far exceeding the Company's target of 26% or more.

CO2 Emissions and Reductions for Logistics (in Japan)

Balancing Customer Satisfaction and CO2 Emissions Reduction

Mazda is taking the following measures to provide customers with the volume they require, with the precise timing they expect, while reducing CO2 emissions.
Efforts to focus on the following three pillars of logistics are being taken by visualizing in detail the hidden logistics issues in each process on a global level.

1. Hub-and-spoke system for transportation of completed vehicles and service parts*1

  • Reforming transportation by consolidating logistics centers for completed vehicles
    By the end of FY March 2012, Mazda consolidated its nine logistics centers nationwide into five locations with the aim of combining delivery routes with low shipping volumes while ensuring timely shipments. Continuously reviewing the operation of domestic vessels (car carriers) according to their shipping volumes has enabled the Company to improve loading efficiency. To make more effective use of the domestic vessels on the return journey, collaborative transportation has also been promoted with other companies.
  • Reforming transportation by reorganizing part suppliers
    In line with the consolidation of parts supply bases, Mazda has been reviewing its transportation methods and routes to make them most appropriate.
    FY March 2012: Starting with consolidation of parts supply bases in eastern Japan and the Tokai region in Japan, the Company promoted shared transportation of completed vehicles and vessels and expanded use of JR transportation.
    FY March 2013: Starting with integration of parts supply bases in the Chugoku, Shikoku, and Kyushu regions in Japan, the Company expanded the range of large-volume transportation and reduced the range of small-volume transportation, so as to increase the load efficiency of trucks and reduce the number of trucks required.
    FY March 2014: The Company reduced the total transportation distance by enabling direct transportation to some dealerships in the Kinki region in Japan.
Hub-and-Spoke System
  • *1In the "hub-and-spoke" system, distribution centers around the country (hubs) act as bases for delivering completed vehicles to dealerships(spokes). In transporting service parts, parts suppliers serve as the hubs and vehicle dealerships the spokes.

2. "Straightening" of logistics network

  • Straight logistics without distribution centers (Vanning at plant, packaging at plant)
    After manufacture of KD*2 parts is complete, they are packaged and loaded into containers at the same location, eliminating the need for shipment between production and packaging locations. At present, the coverage of this logistics system is expanding to engines, transmissions and auto body parts produced at Hiroshima Plant and Hofu Plant.
    Logistics without Distribution Centers (Vanning at plant)
  • Closely locating production and packaging sites for repair-use bumpers to reduce losses in transportation
    Mazda continued reducing losses in transportation by setting up packaging sites for bumpers as close as possible to their production sites, and increased the number of available shipping destinations.The Company also improved the load efficiency of trucks and reduced the number of trucks needed by introducing large returnable racks.
  • *2A manufacturing method wherein parts are exported to overseas production sites, where they are assembled onsite.

3. Continuous improvement to the Milk-Run System*3

In purchasing production parts, deployment of the Milk-Run system was completed throughout Japan by FY March 2008. Today, Mazda is introducing the same system in overseas production sites, with deployment in the Mexico plant completed in FY March 2014, aiming to reduce CO2 emissions by further promoting efficiency in the purchasing and logistics processes across the entire supply chain. Also, the Company is implementing initiatives to optimize packaging volume for purchasing parts, reflecting logistics needs at the beginning of product development process, so as to further improve the load efficiency of trucks and reduce the number of trucks required.

Milk-Run System
  • *3A method in which a single truck visits multiple suppliers to collect supplies. Named after truck routes in rural areas, which picked up milk from each farm.
