Energy consumption and CO2 emissions

Despite implementing energy-saving welding machines,LED lighting, and green power at our headquarters, the total energy consumption for FY 2024 increased by approx. 4.2% compared to the previous year. This increase is attributed to the longer test run times of environmentally friendly engines compared to conventional engines (heavy oil-only engines), even though the production of marine diesel engines decreased from the previous year. But, CO2 emission decreased by approx. 2.7% compared to the previous fiscal year due to the increased use of hydrogen and ammonia, which are non-fossil fuels, and the increase in the non-fossil electricity ratio among electric power companies.

Water consumption

The graph shows our consumption of water over the last five years. We use drinking water and industrial water. We worked to conserve water throughout FY 2024, but, as a result, our total consumption of clean water and industrial water increased by nearly 1% compared with the previous fiscal year.

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 recycaling rates over the last five years and a breakdown of waste in FY 2024. By changing our business structure, we worked to compress our production system and reduce our generation of waste. But, as a result, we increased waste generation by nearly 6% YOY. On the other hand, due to the progress in recycling metal scraps, wood scraps, and slag, the recycling rate increased by approx. 3.1%, reaching 84.9%. We will continue to strive to reduce waste generation and improve the recycling rate. Furthermore, we will continue to ensure proper waste management through strict controls.
