Environmental management data
(The following data are from our major domestic works (Tamano Works, Oita Factory and Chiba Works). Data from other sources are specified wherever applicable.)

Energy consumption and CO2 emissions

The data depicts change of our performance over time in terms of the environmental indicators of Mitsui E&S Holdings. The reform of our business structure has compressed our production system, which has impacted us. These actions combined with the replacement of welding machines and lights with energy-saving LED lighting, and the electricity contract change of main office’s to green power led to a nearly 4% decrease of our total energy consumption in fiscal 2022 YOY. CO2 emissions were reduced nearly 4%YOY.

Water consumption

The graph shows our consumption of service water over the last five years. We use clean water (pure water) and industrial water (recycled water). We worked to conserve water throughout fiscal 2022 and, as a result, our total consumption of clean water and industrial water dropped nearly 17% YOY.

*1 TJ: Tera Joule (=1012J) *2 CO2 emissions were calculated by following the Guidelines for Calculating Corporate Greenhouse Gases Emissions issued by the Ministry of the Environment. CO2 emissions from electric power were calculated by using the adjusted CO2 emission coefficient for designated electric enterprises that was also published by the Ministry of the Environment.

Amount of waste generated and waste recycling rate

The illegal dumping of industrial waste has become a major social issue and we do everything to fulfill our responsibility as a waste generator. We rigorously control manifests and visit waste disposers regularly to conduct on-site inspections. More importantly, we are thoroughly committed to the segregated collection and recycling of waste to reduce the amount of waste. The graph to the right shows the amounts of waste we generated and our waste recycling rates over the last five years and a breakdown of waste in fiscal 2022. By changing our business structure, we worked to compress our production system and reduce our generation of waste. As a result, we reduced waste generation by nearly 15% YOY. At the same time, advances in slag, papers and cloth scraps recycling achieved an approx. 2.8% increase in the recycling rate, increasing it to 81.4%. We will stay committed to reducing the amount of waste we generate and increasing the waste recycling rate. Further, we will continue our rigorous control to ensure the proper disposal of waste.

Environmental management data

Investments and costs related to its environmental preservation efforts that MES spent was 1,292.6 million yen in total. The environmental preservation cost categories are based on the Environmental Conservation Cost Categories in the Environmental Accounting Guidelines 2005.
