The “Life Cycle Zero CO2 Emissions Challenge” takes an approach to zero CO2 emissions not only while driving, but also in the entire vehicle life cycle including materials and parts manufacturing, vehicle assembly, disposal, and vehicle recycling.
Because some next-generation eco-friendly vehicles may increase CO2 emissions in the processes of materials and parts manufacturing, we strive to develop low CO2 emitting materials during manufacture and their widespread use, as well as reducing material usage and the number of parts used. In order to reduce CO2 emissions at the disposal and recycling stages, we further push forward to expand the use of recycled materials and apply eco-friendly designs that make it easier to dismantle vehicles, pursuing “ever-better cars.”
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 chief engineer, including at the development stage. In this system, we conduct Life Cycle Assessment (LCA) which assesses the impact of the vehicle life cycle on the environment at all stages including materials and parts manufacturing, vehicle assembly, driving, maintenance, and disposal.
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.
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 commutes and business travel, along with the driving, maintenance, and disposal of customer vehicles. Based on these standards, Scope 3 total CO2 emissions in FY2016 were 401.75 million t-CO2, of which Category 1 and Category 11 emissions accounted for approximately 97.1% of the total Scope 3 emissions.
To reduce CO2 emissions in its logistics activities, Toyota Motor Corporation is taking measures to improve the transport efficiency of parts for production and replacement, as well as completed vehicles.
In FY2016, CO2 emissions totaled 0.282 million tons (up 2.5% year on year) but we reduced CO2 emissions per unit of workload (transported volume) to 105.2 g-CO2/tkm (down 3.0% year on year).
At the global level, Toyota began assessing CO2 emissions in each country and region in FY2007, and indicated global target guidelines starting in FY2013.
Based on these guidelines, each country and region sets a goal toward which they have been carrying out reduction activities. As a result, Toyota’s global CO2 emissions in FY2016 totaled 2.10 million tons.
The global urbanization trend has created the need for urban transport measures that harmonize vehicles with social systems in order to reduce carbon emissions and allow smooth movement of people. Therefore, Toyota is actively participating in integrated traffic management projects to realize low-carbon mobility societies. In Bangkok, Toyota is a leader of such projects, the alleviation of transportation demand and improvement of traffic flow is underway. This includes a social experiment in Bangkok, which received a grant from the Toyota Mobility Foundation to verify new traffic management methods for alleviating congestion. The project uses Sathorn Road, the most congested road in Bangkok, as a model case.
Toyota is promoting integrated measures in road traffic sectors to reduce CO2 emissions while driving. As one of the initiatives, we will pursue the promoting activities for eco-driving globally among our customers and employees.
Eco-driving leads to improved fuel efficiency and reduced CO2 emissions through soft acceleration, keeping proper inter-vehicle distance and accelerating and decelerating less. Practicing eco-driving is also a good way to ensure safe driving.
