The Taisei Group has set forth “Promoting environmental conservation and creation” in the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole, and clearly stated that it endeavors to reduce environmental impact through the implementation of energy-saving measures and the “3R” policy (reduce, reuse and recycle) and propose technologies and ideas that will facilitate the creation of new environments.
As one of the 2050 Targets, Taisei Corporation has committed to achieve the “final disposal rate of construction by products of 0%” in its 2050 Environmental Targets, TAISEI Green Target 2050. To achieve this target, we aim to reduce the final disposal rate to 3.0% or less by 2030. We ensure thorough compliance with laws and regulations of countries where we operate, and work on setting requirements higher than legally mandated. Based on the understanding that reducing pollutant and waste emissions is a corporate social responsibility, we are aiming to achieve the 0% final disposal rate of construction byproducts from our construction business, through reducing and recycling such byproducts, promoting green procurement, and extending the life of buildings.
Risks and Opportunities
There is a growing need to promote sustainable procurement throughout the supply chain, such as resource conservation, use of materials that can be recycled and reused, and measures to deal with the problem of single-use plastics and other natural environmental pollution caused by waste. At Taisei Corporation, we are working on waste management and the recycling of resources at worksites, adopting materials and equipment that take into account green procurement and the lifecycle from the design stage, and providing technologies to extend the life of buildings.
EMS's Organizational (EMS)
Taisei Corporation operates an Environmental Management System (EMS) based on ISO14001 on a company-wide basis. We have established an Environmental Committee, chaired by the President, which deliberates and decides on environmental policy and environmental targets that are important for environmental management, in addition to medium- and long-term targets and environment-related initiatives that lead to external evaluations.
Recycled Use of Waste Plastics
Construction materials, packaging materials, and other waste plastics are sorted thoroughly and properly recycled by specialized disposal companies. In addition, we are implementing measures to utilize waste plastic by combining it with waste wood products and creating artificial recycled wood products.
Taisei Corporation supports the Plastics Smart Campaign by the Ministry of the Environment.
* Plastics Smart
A campaign by the Ministry of the Environment to promote “a smart way of dealing with plastic” nationwide, including thorough elimination of littering and illegal dumping, and thorough reduction of single-use plastic and sorting and collection.
Utilizing the Green Procurement Guideline in Cooperation with Suppliers
Adoption of Green Procurement Items
(Construction design phase: non-consolidated)
In 2001, Taisei Corporation established and put into effect the Taisei Corporation Green Procurement Guideline to promote the use of materials, equipment and building methods that have small environmental impact during the design, construction, operation and demolition of structures.
We also conduct target management on green procurement items, and the number of items adopted in fiscal 2020 was 11.7 items.
By referring to and reflecting the content of the Green Purchase Law (Act on Promotion of Procurement of Eco-Friendly Goods and Services by the State and Other Entities), we review the subject items every year. In fiscal 2020, 94 items were included in the guideline. Company-wide application of the guideline means we can not only recycle resources but also save energy, reduce CO2 emissions, save resources, avoid use of toxic substances and preserve the natural environment.
The “Program for the Promotion of Resource Recycling of Building Materials through More Advanced Collection Patrol Systems” Received the Ministry of Economy, Trade and Industry's
Industrial Technology and Environment Bureau Director's Award
We operate a “collection patrol system” for many types of waste, including waste plastics at our construction sites in Tokyo. We received the Ministry of Economy, Trade and Industry's Industrial Technology and Environment Bureau Director's Award in the 2020 Resource Recycling Technology and System Awards for a joint initiative for resource recycling of building materials between Taisei Corporation and our consolidated subsidiary and logistics operator Network Alliance Corporation. We are working to recycle soil from construction sites within and across worksites, and contributing to waste reduction and effective resource use of the industry as a whole.
