Challenge 2Life Cycle Zero CO2 Emissions Challenge

Fundamental Approach

To mitigate the various risks posed by climate change, the “Life Cycle Zero CO2 Emissions Challenge” seeks to completely eliminate CO2 emissions not only while driving vehicles, but throughout the entire vehicle life cycle including materials and parts manufacturing and vehicle assembly, maintenance, disposal, and recycling.
Some electrified vehicles may have materials and parts that increase CO2 emissions in the processes of manufacturing. Possible means of reducing this include adopting low CO2 emitting materials during manufacturing as well as reducing material usage and the number of parts used. It is possible to reduce CO2 emissions in the disposal and recycling stages by expanding use of recycled materials and designs that make it easier to dismantle vehicles.
We will accelerate eco-friendly designs as we pursue “ever-better cars.”

Promoting Environmental Management in Product Development (Eco-VAS)

Steady Promotion of Environmental Target Management

To reduce the environmental impact of its vehicles, Toyota has introduced the Eco-Vehicle Assessment System (Eco-VAS) to set and achieve environmental targets such as life cycle CO2 and recyclability, under the guidance of the chief engineer, including at the development stage. Under this system, we conduct LCA (Life Cycle Assessment), which assesses the impact of the vehicle life cycle on the environment at all stages including materials and parts manufacturing, vehicle assembly, driving, maintenance, disposal, and recycling.

Prius PHV LCA Results

Major Initiatives during FY2018

  • Conducted LCA for one new model, three redesigned models (Camry, Pixis Epoch, and Lexus LS), three partially redesigned models (Aqua, Corolla Axio, and Corolla Fielder), and one improved model (Lexus RS).

Environmental Initiatives for the Life Cycle of Next-generation Vehicles

Although CO2 emissions during driving have been reduced for next-generation vehicles, for some models, the amount of CO2 emitted due to materials used and during the vehicle manufacturing process will increase. Toyota believes it is important to reduce CO2 emissions not only while driving but also throughout the vehicle life cycle.

Response to Scope 3

Scope 3 is a standard established to measure CO2 emissions at all stages of a company’s business activities and identify areas for future reductions. Scope 3 accounts for not only CO2 emissions from their activities and those of their consolidated subsidiaries (Scope 1 and Scope 2), but emissions from other stages of the life cycle, such as procured materials and parts, transportation, employee commuting and business travel, along with the driving, maintenance, and disposal of customer vehicles.
The calculation results for FY2018 are overall Scope 3 CO2 emissions of 412.01 million tons-CO2, with category 1 and category 11 combined accounting for the bulk of the total, approximately 97 percent.

Pursuing Transportation Efficiency and Reducing CO2 Emissions in Logistics Activities

To reduce CO2 emissions in its logistics activities, Toyota Motor Corporation (TMC) is taking measures to improve the transportation efficiency of production parts, completed vehicles, and spare parts.
In FY2018, we continued fuel efficiency initiatives, including loading efficiency improvement activities, shortening logistics routes, and so on, reducing CO2 emissions per unit of workload (transported volume) to 104.2 g-CO2/tkm (down 1.0 percent year on year). CO2 emissions from logistics operations totaled 0.286 million tons (up 1.4 percent year on year), due largely to an increase in completed vehicles shipments in Japan.
At the global level, Toyota began assessing CO2 emissions in each country and region in FY2008, and indicated global target guidelines starting in FY2014. Based on these guidelines, each country and region set a goal toward which they have been carrying out reduction activities. Based on these guidelines, each country and region set a goal toward which they have been carrying out reduction activities. As a result, Toyota’s global CO2 emissions in FY2018 totaled 2.17 million tons.

Major Initiatives during FY2018

  • Created a new port site in Amagasaki City, Hyogo Prefecture
  • Began joint transportation initiative by TKM and TKAP, Toyota Affiliates in India
