Environmental Policy and Environmental Targets
Based on the Group Philosophy “To Create a Vibrant Environment for All Members of Society,” the Taisei Group
has set forth in its Environmental Policy and Environmental Targets, the formation of high-quality social capitalthrough corporate activities centered on the construction business in harmony with nature.
The construction industry, which is involved in the formation of social capital, is built on the burden on theenvironment. On the other hand, environmental problems are becoming more and more serious on a global
scale, and long-term countermeasures are required. In response to these circumstances, in 2018 we revised
our medium and long-term goals, the 2050 Environmental Targets (TAISEI Green Target 2050), based on
environmental issues such as climate change, recycling of resources, co-existing with nature, and environmental
pollution risk. As a group, we are striving to accomplish the “Realization of a Sustainable and Environmentally
Friendly Society.”WEB

For Realization of Low Carbon Society▍For Realization of Low Carbon Society（Risks and Opportunities）
For the construction industry, rising temperatures in recent years, large-scale typhoons, anddisasters caused by extremely concentrated heavy rain pose risk factors such as interruptions anddelays in construction work. On the other hand, increased demand for net Zero Energy Buildings(ZEB), which is a measure to mitigate climate change, will lead to the creation of opportunities fororders. In the field of renewable energy, Taisei Corporation is working on ZEB and developing
technologies for floating offshore wind power generation facilities. In addition, we consider thegreen infrastructure promoted by the Ministry of Land, Infrastructure, Transport and Tourism as ameans of mitigating and adapting to climate change as one of the opportunities to receive orders
through our market expansion aimed at strengthening infrastructure, and we are promoting relevant
technology development and design proposals.
● Medium- and Long-Term Initiatives
Taisei Corporationʼs two CO2 emission reduction targets for 2030, which are benchmarks of “TAISEIGreen Target 2050,” have been certified by the SBT initiative. One is the CO2 reduction target atthe construction stage. To achieve this target, we are promoting initiatives to reduce the environmental
impact (TSA) in which all employees participate, as well as energy conservation activities byspecialized contractors (cooperating companies) and the use of heavy machinery and vehicles withhigh energy efficiency. The other target is to reduce CO2 emissions in buildings used by customers.
The Company is promoting the provision of advanced energy conservation and ZEB technology, as
well as the accumulation of construction results. We will work with various stakeholders in the value
chain to achieve our targets.
* SBT initiative[Taisei Corporationʼs SBT per scope]・Scope 1 : Direct emissions associated with fuel use for heavymachinery and vehicles at construction worksites
・Scope 2 : Indirect emissions associated with electricity use atconstruction worksites Reduce greenhouse gas emissions(Scope 1 + Scope 2) by 26% from FY2013 levels by 2030
・Scope 3*: Indirect emissions associated with energy use during theoperational phase of the building delivered Reducegreenhouse gas emissions by 25% from FY 2013 levels
by 2030

Founded in 2015, this organization(initiative) requires companies to establish“Science Based Targets (SBT)” to contribute to
the Paris Agreement, which has set the goalof limiting

Promoting ZEB for Buildings Designed by Taisei
Corporation

Taisei Corporation calculates Scope 3 emissions for ten categories
related to its business.By promoting energy saving and ZEB in buildingsthat we design, the reduction rates of predicted CO2 emissions at thestage of building operations will be improved. This helps reduce the CO2
emissions in Category 11 (use of products sold) in Scope 3 based on the
GHG protocol criteria.We are currently steadily accumulating results andaccelerating the spread of highly marketable ZEB .

The Next Generation R&D Building at theTaisei Advanced Center of Technology● Acquired ZEB Ready Certification for the First Time in Japanas a Temporary Worksite Office
In order to further promote energy conservation at temporary
worksites, we obtained ZEB Ready certification for the first timein Japan for two advanced environment-conscious worksite offices.
The main feature of this initiative is that the combination of highly
versatile equipment and materials meets the ZEB certification
specifications. These specifications are easy to install in temporary
offices, which are often covered by lease contracts. By presenting
them as a standard model of a worksite office in the near future,
this initiative aims to spread energy-saving worksites throughout
the industry.

For Realization of a Recycling Oriented Society▍ For Realization of a Recycling Oriented Society（Risks and Opportunities）
Although it is important to control the quality, delivery time, and cost of materials and equipmentused in construction work, there is a growing need to promote sustainable procurement throughout
the supply chain, such as measures to deal with the problem of disposable plastics and othernatural environmental pollution caused by waste, resource conservation, and the use of materials
that can be recycled and reused.
At Taisei Corporation, we are working on waste management and the recycling of resources atworksites, adopting materials and equipment that take into account the lifecycle from the design
stage based on green procurement, and providing technologies to extend the life of buildings.

●Utilizing the Green Procurement Guideline in Cooperation with Suppliers
In 2001, the Taisei Corporation Green
Procurement Guideline was established and put
into effect to promote the use of materials,
equipment and building methods that have small
environmental burden during the design,
construction, operation and demolition of
structures. By referring to and reflecting thecontent of the Green Purchase Law, we review
the subject items every year.
In FY2019, 93 items were included in theguideline. Through CSR procurement, we arealso Promoting environmental consideration for

be treated. 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 theEnvironment.
As initiatives for the recycling of water resources, we implement on-site utilization of rainwater and springwater as part of our efforts to reduce the environmental Impact at construction sites. We provide sandbasins and water retention tanks to store water and prevent flooding in case of heavy rain and also to settle
dust by sprinkling the stored water.
*Plastics Smart

dealing with plastic” nationwide, including thorough elimination of litteringand illegal dumping, and thorough reduction of single-use plastic and sortingand collection.

TAISEI Environmental Report 2020 6

ISO26000 The Environment

For Realization of a Recycling Oriented Society●Resources at Worksites
The emission volume of construction waste varies
depending on the scale and type of construction. In
general, the bigger the construction is, the larger theamount of waste becomes.
However, most of the waste is strictly sorted andtransported by specialists. Then, it is treated byremoving dirt which became attached after construction and recycled. The ratio of the final disposal of theemitted waste, such as disposal at the final waste
disposal site, is less than 4%.
Currently, we operate a “routine collection system”
for many types of waste, including waste plastics at
our construction sites in Japan. In the future, we willcontinue to analyze data to obtain an efficientcollection frequency as well as mechanisms forcollaboration between construction sites, andstabilize the loading ratios of collection vehicles. We
arealso
consideringpromotingnationwide
deployment and aim to achieve a final disposal rateof 0% for construction waste in 2050.

Environment pollution caused by construction has a significant impact on the surroundings and society.
Compliance with environmental laws and regulations is always one of the most important environmental
issues. We keep contributing to the reduction of environmental risks of society by promoting the proper
management of construction waste, the development of new technologies and measures to cope with theregulations for soil pollution which are expected to become stricter than now.

●Risk Measures at Worksite
With a worksite environment patrol, the Environment
Department of the Head Office nd branches conduct aninternal audit to check the observance of the environment law
at worksites. As for the findings, we establish corrective andpreventative measures for continuous improvement. At aworksite, based on the Environment Management manual, we
provide environmental education to our employees andspecialized contractors. By sharing the cases that could result inan environmental accident, issuing notifications of the proper
management of toxic substances such as asbestos and PCB,
and reinforcing adequate control and treatment of polluted soil,
we have been raising awareness of the importance ofenvironment management and the prevention of environmentrelated accidents.
Regarding the management of water resources, Taisei
Corporation is working to “prevent water pollution caused byconstruction wastewater, and the like” as a management
priority. In FY2019, there were no water pollution caused byconstruction wastewater or violations of environmental laws .

Risk Measures at Worksites
Type

Measure (Example)

Dust

In response to a complaint about the dust
generated by construction, we implemented
measures such as water sprinkling andinstalling sheets.

Noise

In response to a complaint about the noise
generated at the nighttime concrete-related
work, we made early notification to theneighborhood.

Vibration

In response to a complaint about vibration
caused by heavy machinery work in the factory,
we changed our schedule to carry out work on
factory holidays.
In response to fuel leaks from a crane barge,

Water we used absorption mats for recovery and took
pollution recurrence prevention measures.

●Complaint to Worksites and Handling Thereof
We take proper measures regarding
environment-related complaints addressed
to a workplace, make a record and reportusing a communication sheet based on anenvironment management system (EMS)
procedure and share the information
horizontally among concerned departments
or within the entire Company as required. In
addition, we are properly handlingcomments given by citizen groups.

●Technical Case Study●

Developed a Cutting-Edge Method of Demolishing Skyscrapers Known as“Tecolep-Light system”
We successfully developed “Tecolep-Light system,” a cutting-edge method of demolishing skyscrapers. The
Tecolep system is an environmentally-conscious method of demolishing skyscrapers by repeatedly jacking
down from the upper level, while minimizing dust, noise, and other particles, etc. which may negatively
affect the surrounding environment.
Unitized lightweight roof structures can reduce the time to create a closed space, allowing demolition work
to be completed in a shorter period of time.

Third-party Assurance of Environmental Data within the Taisei GroupOver the past five years, we have standardized and manualized the method of collecting and aggregating
environmental data such as the quantity of energy consumed, the quantity of CO2 emissions and the volume
of industrial waste for the 7 main group companies participating in the Taisei Group Environmental
Promotion Conference. In FY2018, continuing from the previous year, the 7 main group companies received
third-party assurance for their actual performance data.
Among the group companies, TAISEI ROTEC CORPORATION, TAISEI U-LEC CO., LTD., TAISEI SETSUBI
CO., LTD. and J-FAST Co., Ltd. were inspected by auditors visiting their head offices, major offices andfactories.
Third-party assurance not only guarantees the data reliability but also leads to a review and improvementof the management structure and initiatives of each group company.
●Data is rounded off; therefore, the total value may not equal the sum of the parts.

with the Act on the Rational Use of Energy, the Act on Promotion of Global Warming
Measures, and the GHG Protocol, etc.
- Energy-related and water consumption- Civil Engineering and Building Construction (sites): Consumption in a two-month
period in FY2019 is sampled at 178 construction sites to calculate the consumption
per unit of construction turnover (basic unit). Annual consumption is calculated bymultiplying this basic unit by the construction turnover for the year. For civilengineering, this calculation is performed for each construction type.
* Energy-related: Fossil fuels (heavy oil, diesel, gasoline, kerosene), electrical power, city gas, and
LPG consumption and their energy-equivalent values.
