Daihatsu has strongly promoted activities aimed at reducing CO2 emissions. At its production sites and offices worldwide, the company has engaged both in improving energy efficiency and in eliminating excess.
Daihatsu will continue its efforts to achieve environmentally friendly plants that emit no CO2.
Daihatsu’s CO2 emissions at its Japanese production sites in FY 2019 fell to 274 kilograms CO2 per vehicle produced unit, in part due to production line optimizations. This is a reduction of 44% compared to baseline values from fiscal 2001.
We also succeeded in reducing its total CO2 emissions by 25%.
We will continue to make efforts to reduce our environmental load by further improving energy efficiency.
Daihatsu has announced it’s the Seventh Daihatsu Environmental Action Plan, which runs until 2025. We will continue its pursuit of making cars in an environmentally friendly manner, with the goal of achieving “zero” CO2 emission by 2050.
In order to achieve its goals, we will make continual improvements, develop and incorporate innovative technologies, and focus on the use of solar power-based renewable energies.
Daihatsu promotes wide-ranging energy-saving measures at its production plants, such as implementing drastic line innovations and updating aging facilities with highly efficient facilities.
Transition to LED lighting
In order to reduce energy consumption, Daihatsu is transitioning all its lighting—including mercury lamps and fluorescent lights at its plants, as well as its office lighting—to LED lighting.

Promoting SSC at its production lines
In order to realize the affordable manufacturing technologies it has developed through its K-cars [mini vehicles], Daihatsu has carried out production line optimizations based on the SSC (Simple, Slim, Compact) concept.
It has led to a significant reductions in energy consumption.
Daihatsu Motor Kyushu Co., Ltd. Vehicle Plant
Plant No.1 and Plant No.2 both have the same production capacity of 230,000 vehicle units per year. However, Plant No.2 occupies just half the space of Plant No.1 and, as a result, achieves more compact air conditioning, lighting, and facilities.
Simplifying body-carrying devices in the welding process
Daihatsu has significantly reduced the energy required to drive the pallets used to carry and fix the positions of bodies in the welding process by simplifying and lightening them.
Introduction of renewable energies
As well as saving energy through eliminating waste during the production process, Daihatsu will also actively seek to expand its introducing renewable energies.
Full-scale introduce at Shiga Plant
In addition to its production plants, Daihatsu’s Head Office and technology division are also implementing energy-saving measures.
We take care to carry out everyday energy-saving measures such as appropriately setting air conditioning temperatures, and switching off unused lighting; we have also transitioned from the use of fluorescent to LED lighting, introduced sensor-based on/off lighting controls, and are engaged in solar power generation initiatives as well.
The offices have also introduced systems that enable the control of individual office LED lights, enabling energy to be saved by switching off unnecessary lights, and allowing energy consumption to be monitored.
The above initiatives have raised awareness of energy-saving measures among department employees.
