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.
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).
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).
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.
