Challenge 3 Plant 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 will work on both the introduction of innovative technologies and daily kaizen, and the introduction of renewable energy and utilization of 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 energy such as solar power and wind power along with hydrogen energy, and we are committed to continuing working hand in hand with stakeholders to build the necessary infrastructure to support the widespread use of these energy sources.

Through these initiatives, we will contribute to achieving SDG 7.2 (introduction of renewable energy), 7.3 (improvement in energy efficiency), 9.1 (infrastructure development), 9.4 (sustainable production processes), and 13.1 (reduction of CO2).

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 FY2019, Toyota Motor Corporation (TMC) reduced total CO2 emissions to 1.11 million tons (down 2.9 percent year on year), and CO2 emissions per unit produced to 0.387 tons (down 1.8 percent year on year). Globally, total CO2 emissions were 7.65 million tons (down 1.8 percent year on year), and CO2 emissions per unit produced were 0.712 tons (down 3.8 percent year on year).

Trends in Global Total CO2 Emissions (from Energy Consumption at Stationary Emission Sources) and CO2 Emissions per Unit Produced

Major Initiatives during FY2019

  • Introduced innovative technologies (electrostatic adhesion technology) in painting processes to achieve improvement in coating efficiency and reduction in ventilation volume
  • TMT, a Thailand-based affiliate, took measures to reduce energy consumption during parts transportation to almost zero by introducing a karakuri method for its vehicle assembly process to facilities at its Ban Pho Plant

Introduction of Renewable Energy and Utilization of 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 FY2019, we generated 39,528 MWh of renewable electricity globally.

Installation of a Wind Power Generator at Tahara Plant

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