Challenge 3Plant Zero CO2 Emissions Challenge

Fundamental Approach

Since CO2 is emitted not only when vehicles are being driven, but during the manufacturing process, the restraint of CO2 emissions to suppress climate change is also a challenge for manufacturing plants. The two main pillars of this challenge are manufacturing technology improvement and switching energy types.
In the area of manufacturing technologies, simplifying and streamlining our processes to reduce their complexity and the time they require enable us to reduce CO2 emissions. We can also obtain reduction effects by raising energy efficiency in manufacturing processes. Furthermore, we use every possible means to reduce CO2 emissions including introducing an innovative process called “Karakuri” that does not consume any energy at all.
Regarding initiatives on the energy used, we will effectively utilize renewable energies such as solar power and wind power along with hydrogen energy.

Reduce CO2 Emissions in Production Activities

Activities to Reduce CO2 Emissions in Production Activities

In our production activities, we have been developing and deploying low-CO2 production technologies along with taking daily measures to achieve our reduction targets.
In FY2016, TMC reduced its CO2 emissions per unit produced to 0.398 tons (down 2.5 percent year on year) against total CO2 emissions of 1.16 million tons (up 0.7 percent year on year). Also, our CO2 emissions per unit produced was 0.747 tons (up 0.5 percent year on year) in contrast with global CO2 emissions of 7.87 million tons (up 4.1 percent year on year).

Major Initiatives during FY2016

  • Won the 63rd Okochi Memorial Production Prize, one of the most prestigious awards in industrial circles in Japan, for developing a new car painting line that reduces our environmental footprint

Promoting the Use of Renewable Energy

We have also introduced the No. 1 regional CO2 reduction activities by using renewable energies that meet the needs of each country and region. TMC led the way at the Tsutsumi Plant, producer of the Prius, with the deployment of a solar power generation system generating rated power of 2,000 kW, which is equivalent to the electricity for 500 households. Moving forward, we will actively introduce renewable energy systems after considering the balance of environmental, regional, and economic factors.

Major Initiatives during FY2016

  • Also installed solar panels and introduced renewable energy at the TMC Honsha Plant and Toyota Motor Manufacturing Kentucky (TMMK; U.S.) and Toyota South Africa Motors (TSAM)
  • At the energy management building located at the Honsha Plant, introduced the use of stationary pure hydrogen fuel cells and began a verification test with the goal of reducing CO2 emissions to zero
  • Reduced CO2 emissions at Toyota do Brasil Ltda. (TDB) by controlling its facilities in accordance with line operational status (including optimizing operating time of the stored-heat combustion and deodorization device and automated system to turn off the tower during machine downtime)

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.
