In line with our Environmental Challenge #3 (Plant Zero CO2 Emissions Challenge) the plant in Japan where the new Prius Plug-In hybrid vehicle is manufactured strives to reduce its environmental impact in a number of ways. By streamlining and simplifying certain processes, to the adoption of Karakuri Kaizen which is the elimination of unnecessary effort that required energy, through to the increased use of renewable energy. For example, the plant has developed new technology in the painting process and also installed a 2000kW photovoltaic system; these all go to reduce CO2 emissions during the production phase.
The plant has introduced more stringent water standards than the legal requirements, aiming to return water that is cleaner than that originally used to the local river system (Environmental Challenge #4). A biotope where indigenous species such as Japanese rice-fish, Crucian, and Dragonfly flourish, was created with an aim to increase interaction with the local community based around biodiversity conservation.
Finally, this manufacturing facility also has a company slogan that encourages tree planting! Environmental Challenge #6 that outlines our drive to establish a future society in harmony with nature has ensured the engagement of employees, families and local residents and has so far resulted in the planting of more than 50,000 trees.
