Environmental Management in Production (Eco Factory)

Basic Stance

DENSO has worked to implement measures against global warming, reduce the loss of resources, and decrease the use of chemical substances by means of various proprietary techniques. In particular, we believe in the importance of energy conservation and energy conversion as measures to counter global warming. Specifically, this means reducing fossil fuel consumption and promoting a shift to renewable energy sources over the long term.

Based on this concept, DENSO charges departments according to their energy consumption (direct-charge system) and implements a system of Just-in-Time (JIT) energy to supply only the required amount of energy when needed.

In addition, we created the Denso-Environmental Performance Communicator (D-EPC) that can swiftly tabulate environmental data from production sites worldwide. We are using it as a management tool from the perspective of environmental governance.

Specific Initiatives

Evolution of the Eco Factory

At DENSO, we have formulated and promoted Eco Factory Guidelines targeting the entire Group since 2007. In 2016, these guidelines were updated and promoted as DENSO Group Production EMS. We want to maintain the highest global level of overall Group environmental management by visualizing the position of each Group company and promoting ongoing improvements in each company while sharing objectives that must be achieved throughout the Group.


This EMS involves the setting of 76 categories that include four perspectives in the five areas of wastewater, oil and chemicals, the atmosphere, noise, and waste, and is operated based on Global Common Guidelines establishing five stages of activity levels in each region. Certification is, in principle, confirmed by QC diagnostics (once every three years), with certification granted at the company or factory level.
