Given the international scope of climate-oriented demands on society, typified by the Paris Agreement, Toyo Construction is keen to contribute to realizing a carbon-neutral society by lowering CO2 emissions from business activities and by participating in offshore wind power construction projects. Toward this end, we are involved in the construction of a cable-laying vessel and technology development. We are developing technology to immobilize CO2 captured from factory exhaust and the atmosphere in water stored at marine final disposal sites. In September 2024, this technology was adopted by Aichi Prefecture under the Aichi Environmental Innovation Project initiative. In addition, we are engaged in activities aimed at curbing CO2 emissions, including marine demonstration tests on algal reef blocks, which have the potential to immobilize carbon as blue carbon, and the use of low-carbon, environmentally friendly concrete in construction projects. Also, as a member of the GX League, we will carefully track trends in climate change countermeasures and take a robust approach toward developing technology that helps prevent global warming.Trends in CO2 emission reduction rate targets and actual results (domestic, parent-only/unit during construction)(%)Civil engineering (onshore)55.3The main source of CO2 emissions at construction sites tends to be the heavy equipment and construction equipment in operation at these locations. In marine construction, which is our forte, work vessels running on Bunker A are the main source of CO2 emissions. As a marine contractor, we need to find ways to reduce CO2 emissions from work vessels in operation and are taking steps to switch to environmentally friendly engines and shift away from Bunker A in favor of light oil, that is, diesel. Going forward, we will establish technologies for converting to GTL*1 and biofuels as well as for capturing and immobilizing CO2 from work vessels.Trends in the CO2 emission amount per 100 million yen of completed work(t-CO2/100 mil. yen)605040302010–10100755025The Toyo Construction Group sees the realization of a carbon-neutral society and efforts to reduce the environmental impact as priority issues and seeks to address climate change while engaging in R&D and other pursuits that contribute to preserving natural ecosystems.Efforts to tackle climate changeBasic conceptInitiatives in CO2 emission reduction60.748.233.630.18.78.72019202054
