CO2 Emissions of Taisei Corporation Group (FY 2014)

CO2 Emissions of Taisei Corporation Group (FY 2014)

The method of determining environmental data such as the quantity of energy consumed and the quantity of CO2 emissions for the 7 main companies participating in the Taisei Corporation Group Environmental Promotion Conference has been standardized and produced in a manual, for sharing and use in initiatives for reducing environmental impact. Data has been calculated based on the new FY 2014 manual. Taisei Rotec Corporation produces composite materials used in roads, so their CO2 emissions are highest of all the 7 main group companies. Taisei Corporation and Taisei Rotec Corporation together account for more than 90% of the CO2 emissions of the group as a whole. Third party verification of the Taisei Group CO2 emissions has been carried out for Taisei Corporation and Taisei Rotec Corporation.

Supply Chain (Environment)

Promoting CSR Procurement

TAISEI established a Procurement Policy in April 2013 with the aim of fulfilling its CSR throughout the supply chain, in order to help create a sustainable society. We developed Procurement Guidelines describes energy use, waste, biodiversity impacts based on this policy and will pursue CSR procurement through the establishment of good partnerships with suppliers. We are proactively engaging with the main group companies as our of supply drains.

TOPICS

Capacity Building with Group Companies

The factory-prefabricated, precast concrete (PC) used in the housing construction of Taisei U-Lec Co., Ltd. and Taisei Housing Corporation have excellent environmental performance, such as reduced noise and vibration and dust compared with the conventional construction methods of concrete structures, reduced labor and vehicle requirements, shorter construction periods (reduction in CO2 emissions) due to the factory production, and reduced quantity of timber formwork and waste (effective utilization of resources). In addition, the fi re resistance, seismic resistance, and durability of concrete contributes to fireproofing of urban areas with a high density of wooden houses, thereby contributing to disaster resistant urban development, so this is an initiative of the group as a whole.

Environment Related Technologies and Initiatives

TOPICS

Reducing water use

Taisei Corporation has developed its own proprietary technologies for the treatment of water, such as its water-saving high-performance filtration system and its sea water recycling system.
In recent projects, such as the implementation of Taisei's artificial sea water production system, significant reductions have been achieved in not only the amount of sea water transported to inland urban aquariums, but also all associated CO2 emissions. An effective combination of these technologies can reduce the amount of sea water used at such aquariums and minimize wastage. These systems have now been adopted at Kyoto Aquarium (Shimogyo Ward, Kyoto City), Sumida Aquarium (Sumida City, Tokyo) and other large inland aquariums.
