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.
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).
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.
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.
