Better Buildings, Better Plants Challenge partners strive to decrease portfolio-wide source energy use intensity, and to increase the percent improvement compared to a set baseline. Toyota's portfolio consists of ten manufacturing plants. Their energy management activities are a part of the company's corporate social responsibility initiative, Toyota's 2050 Challenge, which consists of six challenges. Challenge 3 focuses on establishing a culture of energy (CO2) awareness and efficiency. Identified energy saving opportunities are shared among the manufacturing facilities. Toyota has made substantial use of system assessment and energy Kaizen events to identify energy saving opportunities.


Looking at the percent improvement in energy performance across all facilities can help a company quantify the benefits of process and facility upgrades. Several of Toyota's facilities are off to a good start posting significant improvements during the first reporting year, conversely, plant expansions and modifications have increased the energy intensity at a few plants. These facilities are a focus for future efficiency efforts. Toyota continues to make progress toward the corporate goal of 20% reduction in energy intensity through self-assessment, facility and process improvement.


Each Toyota plant has its own energy intensity metric described as source energy per unit of output, with each plant producing a different product. These outputs include number of vehicles produced, number of engines, and power train components (castings and forgings) produced. The absolute change and percent change in source energy use, production output and energy intensity are tracked for each facility on both a monthly and annual basis. Toyota normalizes its plant-level numbers to account for external factors that impact energy use such as changes in production volume and heating and cooling degree days. These metrics are rolled up to the corporate level, with a corporate-wide percent improvement in energy intensity calculated by taking a weighted average of the percent change in energy intensity at the individual facilities.

Portfolio Water Performance

Better Plants Water Savings partners strive to decrease portfolio-wide water use intensity, and to increase the percent improvement compared to a set baseline. Toyota's portfolio consists of 10 plants as of FY2019. With a water intensity improvement of 2% since its baseline year of FY2014, Toyota is aggressively targeting projects to help the organization meet the 20% water use intensity goal. Toyota's water use intensity improvement has been driven by new efforts to reuse water, new filtration efforts in its paint shops, and through continuous improvement Kaizen events. As with energy, water conservation is also a part of Toyota's 2050 Challenge as Challenge 4.
