Challenge 3Plant Zero CO2 Emissions Challenge

Fundamental Approach

The Plant Zero CO2 Emissions Challenge seeks zero CO2 emissions in the vehicle manufacturing process. To achieve this, Toyota is introducing innovative technologies, conducting daily kaizen, introducing renewable energy, and utilizing hydrogen. First of all, processes and the time required were reduced by simplifying and streamlining manufacturing processes, which made an improvement to energy use efficiency, including equipment optimization and the use of waste heat. Furthermore, we use every possible means to reduce CO2 emissions including introducing an innovative process called karakuri that does not consume any energy source at all.
In addition, we will effectively utilize renewable energies such as solar power and wind power along with hydrogen energy.

Reduce CO2 Emissions in Production Activities

Introduction of Innovative Technologies and Daily Kaizen

In our production activities, we have been developing and introducing low-CO2 production technologies along with taking daily improvement measures to achieve our reduction targets.
In FY2018, we reduced total CO2 emissions to 1.14 million tons (down 1.4 percent year on year), and CO2 emissions per unit produced to 0.394 tons (down 1.1 percent year on year).

Major Initiatives during FY2018

  • In an effort to eliminate the use of steam at the TMC Head Office, facilities were replaced with equipment that does not use steam, high-efficiency compact boilers were installed, and other measures were taken so the Head Office drive force boiler could be taken offline
  • At TKM, an affiliate based in India, energy usage was cut by controlling temperature and humidity in painting booths

Introducing Renewable Energy and Utilizing Hydrogen

Toyota is promoting the introduction of renewable energy, taking into consideration the characteristics of each country and region. When introducing renewable energy, we place the highest priority on in-house generating facilities (such as solar power generation) and in-house consumption at Toyota plants and other facilities.
In FY2018, we generated 17,578 MWh of renewable energy globally (see pp. 31.33 for information on hydrogen use).


Toward Realizing a Decarbonized Society in 2050: Effective Use of Renewable Energy

Installation of a Wind Power Generator at Our Tahara Plant

We are pushing forward with plans to install a wind power generator at the Tahara Plant by around 2020 aiming for using the use of wind power produced on-site.
