- FY2026AdvancedAnnual report
「By introducing 912.4 m³ of ECM (Energy, CO2, Minimum) concrete and 273 CO2-SUICOM precast embedded forms (163.8 m²), CO2 emissions were reduced by approximately 45 tonnes compared with construction using the concrete in the original plan. This represented a reduction of approximately 12% of the total CO2 emissions from the invert concrete of the temporary drainage tunnel.」
Environmentally friendly concrete was applied on a large scale to a construction project directly administered by the Ministry of Land, Infrastructure, Transport and Tourism, reducing CO2 emissions by approximately 45 tonnes, or approximately 12% of emissions from the concrete covered. The deployment of environmental technologies in actual construction projects is progressing. - 2026-06-03AdvancedGeneral Meetings of Shareholders
「Based on Kajima Environmental Vision 2050 plus, we are focusing on initiatives in three mutually related areas: decarbonization, resource circulation and nature regeneration.」
The company continued its focus on the three areas under Environmental Vision 2050 plus and cited the large-scale application of environmentally friendly concrete, investment in a forest fund and the use of timber from company-owned forests in wooden buildings as achievements. - FY2024ReframedAnnual report
「The Kajima Environmental Vision: Triple Zero 2050, formulated in 2013, was revised in 2024 and published as Kajima Environmental Vision 2050plus. Regarding CO2 emissions reduction, the Company aims to reduce Scopes 1 and 2 by 42% and Scope 3 by 25% from fiscal 2021 levels by fiscal 2030, and to achieve net zero, or carbon neutrality, by fiscal 2050.」
The previous environmental vision was revised as 2050plus and reorganized into 3 areas: decarbonization, resource circulation and nature regeneration. The fiscal 2030 targets for Scopes 1, 2 and 3 and the fiscal 2050 net-zero target for CO2 reduction have been maintained and made more specific. - FY2023RaisedAnnual report
「Regarding CO2 emissions reduction, the Company revised its targets in 2023. It aims to reduce CO2 emissions generated during construction, covering Scopes 1 and 2, by 42% from fiscal 2021 levels by fiscal 2030 and to achieve net zero, or carbon neutrality, by fiscal 2050.」
The environmental targets were revised, explicitly stating a 42% reduction in Scopes 1 and 2 by fiscal 2030 and net zero by fiscal 2050. Targets were also stated for Scope 3, comprising a 25% reduction by fiscal 2030 and net zero by fiscal 2050, strengthening the scope, numerical targets and deadlines. - FY2021RaisedAnnual report
「The Company will accelerate activities under the Kajima Environmental Vision: Triple Zero 2050, target carbon neutrality by 2050, and pursue business activities that take a comprehensive approach to the environment, including resource circulation and biodiversity.」
The time horizon and scope of the targets were expanded from conventional efforts to reduce carbon emissions and develop environmental technologies to addressing the transition to a decarbonized society, with carbon neutrality by 2050 explicitly stated. The development and commercialization of CO2-absorbing concrete, CO2-SUICOM, and energy-saving air-conditioning systems are also described. - FY2020AdvancedAnnual report
「Hareza Tower in Toshima-ku, Tokyo, designed and constructed by the Company, obtained the first ZEB Ready certification for a high-rise mixed-use building, indicating an energy consumption reduction rate of at least 50%.」
In environmental technology, the Company obtained the first ZEB Ready certification for a high-rise mixed-use building. It also expressed its support for the TCFD recommendations, expanding the scope of its response to environmental performance and climate-related information. - FY2019AdvancedAnnual report
「In addition, low-carbon ECM concrete, developed in 2014, which reduces CO2 emissions during production by approximately 60% through the use of 60–70% finely ground blast-furnace slag in place of ordinary cement, was applied to a civil engineering structure for the first time. Environmentally friendly, low-carbon concrete using finely ground blast-furnace slag, including ECM concrete, received the 2019 Architectural Institute of Japan Award for Technology jointly with Takenaka Corporation.」
In environmental technology, concrete that reduces CO2 emissions by approximately 60% was applied to a civil engineering structure for the first time, and the technology subsequently received an award. - FY2018ReframedAnnual report
「The Company will strengthen its efforts to address social issues, including the global environment and disaster prevention and mitigation.」
Environmental technologies are positioned not merely as the development and application of individual technologies, but as part of efforts to address social issues involving the global environment and disaster prevention and mitigation. - FY2016First statedAnnual report
「In August 2015, the Research Building at the main building of the Company's Technical Research Institute obtained LEED-EBOM Platinum certification, the highest rating. The Research Building is positioned as a leading project toward achieving the Company's ZEB (zero-energy building) target. Since the building began operations in November 2011, various technologies developed by the Company have been applied to improve energy efficiency. Primary energy consumption in fiscal 2014 was reduced by approximately 52% from the office benchmark.」
The environmental technology results and initiatives described include LEED-EBOM Platinum certification, an approximately 52% reduction in primary energy consumption, and construction technologies for offshore wind power facilities.
