Realization of a Sustainable and Environmentally Friendly Society
By improving and applying environmental technology, the Taisei Group is striving to achieve the 2050 Environmental
Targets “Sustainable and Environmentally Friendly Society” involving the entire value chain in unity.

Promotion of Environment Management Activities
We established the Environmental Policy to work on the formation of high-quality social capital through our corporate activities
having the construction business as the core in harmony with nature under the Taisei Group’s philosophy, “To create a vibrantenvironment for all members of society.” Based on this policy, we set up the 2050 Environmental Targets and identify ESG materiality, and clarify our position to help reduce the burden on the global environment.

Activities to Reduce Environmental Impact,
TAISEI Sustainable Action (TSA)
Taisei Corporation is promoting company-wide activities to reduce environmental impact, such as by promoting paperless meetings, adopting LED
temporary lights, ensuring energy-saving operation of heavy machinery andvehicles, using hybrid-type heavy machinery, utilizing renewable energy andarranging a green environment that pays attention to people’s wellness,under the name of TAISEI Sustainable Action.
Through the promotion of TSA, we are reducing greenhouse gases (CO2)by improving the efficiency of energy usage for the construction stage at all
worksites and utilizing renewable energy.
Moreover, to have employees and many people involved in construction
recognize the importance of reducing environmental impact, we distributethe “Guideline for the Achievement of Targets,” which presents detailed“Guide for Achieving Targets”

examples to demonstrate the relationship between environmental impact
reduction and the improvement of productivity. We also established a newaward system to evaluate ideas about environment activities, which can beused as a model, as well as ambitious challenges. In this way, we aim toachieve Environmental Targets.

For Realization of Low Carbon Society
For Realization of Low Carbon Society (Risks and Opportunities)
In recent years, the trend toward rising temperatures, together with disasters brought about by larger typhoons and extreme
torrential rain, have become environmental risk factors that cause interruptions and delays in construction for the constructionindustry. At the same time, Zero Energy Building (ZEB), a measure to mitigate climate change, has created new business opportunities by solving and responding to problems with technology and initiatives. “Adaptation to climate change” was stated as one of
the socio-economic background factors required for green infrastructure, in the “Green Infrastructure Promotion Strategy” announced by the Ministry of Land, Infrastructure, Transport and Tourism in July 2019. Taisei Corporation regards the “expansion ofmarkets for strengthening infrastructure against climate change” as an opportunity to receive orders, and is working to expand thisopportunity by promoting technological development and design proposals related to “green infrastructure,” which will alleviate andreduce damages using natural functions.
Taisei Corporation refers to the TCFD (Task Force on Climate-related Financial Disclosures) recommendations to identify risks andopportunities that account for the effects of climate change over the short- to long-term, employ the identified items in various
initiatives in its EMS (Environmental Management System).
For environmental risks (negative impact) and opportunities (positive impact), please refer to “Important ESG Tasks for the Taisei Group (Materiality)
and Impact on Corporate Activities” on p.14 of TAISEI ANNUAL REPORT 2019.

Major Results in FY2018● SBT Certification and Medium and Long-Term Activities

Taisei Corporation’s greenhouse gas reduction target was certified by Science Based Targets (SBT), an international initiative. Our
CO2 emission reduction target for 2030, which is a benchmark of Environmental Target 2050, was recognized as having a scientificbasis, and contributes to the achievement of the target of the Paris Agreement to keep the temperature to less than two degrees
Celsius above the level before the Industrial Revolution.
Through the popularization of ZEB and environmentally friendly designs for customers, we have been working on reducing
environmental burden and CO2 at worksites in Japan during construction by establishing CO2 reduction intensity targets (comparedwith the value of finished work) for the building operation stage (Scope 3) and construction stage (Scope 1+2). Our 2030 target
certified by SBT was reflected in the annual Environmental Targets. To achieve the targets, in addition to implementing TSA (seep.2), we will cooperate with various stakeholders including supply chain partners and customers to reduce the emission amount.

Taisei Corporation’s SBT:
Reduce Scope 1 + 2 emissions (CO2 at construction stage) by 26% by 2030
Reduce Scope 3 emissions (CO2 at building operation stage) by 25% by 2030

In the Shinagawa Season Terrace, a multi-purpose building that makes effective useof the upper part of the Water Reclamation Center, we built a reservoir for rainwater inthe basement of the Center, in order to temporarily store water during the early stagesof heavy rain, to prevent polluted water from flowing directly into the sea. The building
demonstrates other multifaceted functions of green structures, including the creationof a wide open green space situated on artificial ground constructed above theground, reduction of the heat island effect on the city by using this greenery to coolwind from the Tokyo Bay before sending it into the city area, and conservation of
biodiversity by fostering new ecosystems through waterfront creation using rainwater.

For Realization of a Recycling Society (Risks and Opportunities)
Most of the materials used for the construction business are limited natural resources. Japan imports most of the raw materials.
Therefore, when the supply of materials becomes unstable due to a disaster caused by an extreme climate, it may create a significant risk to business continuity. By promoting green procurement, Taisei Corporation aims to achieve a recycling society by considering the life cycle of selecting materials from the building design stage and providing technology that enables buildings to last
many years.

For Realization of a Nature Co-Existing Society (Risks and Opportunities)
There is always a concern that construction would significantly affect the surrounding environment including nature. During theplanning phase, we extract risks such as the violation of environmental laws and regulations as well as opportunities including
chances to add value. We pay attention to biodiversity until the operation and management support phase after construction, andprovide solutions to create a rich environment to customers. We will contribute to the achievement of a society that cohabits withnature by properly evaluating the value of natural resources to utilize for the development of infrastructure and buildings andreducing the influence of construction.
Major Results in FY2018● Biodiversity-Conscious Research, Planning, Construction and Monitoring

With Ecological Planning, our proprietary environment planning technology, Taisei Corporation contributes to the realization of anature co-existing society by analyzing the natural environment of construction sites and surroundings, carrying out planning basedon predictive estimates and monitoring the construction and post-construction status. In addition, based on our long years ofexperience, we developed “Ikimono Concierge,” a tool that conducts a predictive estimation of animals that could be introduced toa planned site and “Mori Concierge,” a tool to select plants suitable for the environment of a planned site. Using these tools, we
provide high-quality proposals that contribute to cohabitation with nature.
● Biodiversity Conservation and Creation Activities

In the construction of the Sapporo Dome, which was completed in 2001, we used our
proprietary ecological planning technology from the planning stage.
In order to verify that the environment is actually inhabited by various types of living
creatures, we have conducted long-term monitoring surveys based on the number of
species of birds, butterflies, dragonflies, and other creatures, from the planning stage in1997 to the completion of construction in 2001, at both 3 years and 10 years after
construction, and also in the present day.
Knowledge and concrete results accumulated during this process have been used
for the development of the biodiversity communication tools, the “Ikimono (living creatures) Concierge,” and have contributed to the conservation and sustainable use ofnatural resources through various environmental awareness activities conducted by

support in FY2018 through fundraising to donate the cost of planting saplings for thereforestation of Kamaishi Forest. We were also involved in the construction of Kamaishi
Unosumai Memorial Stadium, where trees that had been felled by the fire in Unosumai
District were used to make wooden seats, public toilets, benches and louvers sunshades.

For Realization of a Safety Secured Society
For Realization of a Safety Secured Society (Risks and Opportunities)
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 ofenvironmental risks of society by promoting the proper management of construction waste, the development of new technologies
and measures to cope with the regulations for soil pollution which are expected to become stricter than now.
Major Results in FY2018● Risk Measures at Worksites

With a worksite environment patrol, the Environment Department of the head office and branches conduct an internal audit
to check the observance of the environment law at worksites.
As for the findings, we establish corrective and preventative
measures for continuous improvement. At a worksite, basedon the Environment Management manual, we provide environmental education to our employees and specialized contractors. By sharing the cases that could result in an environmental

Measure (Example)

Noise

In response to a complaint about the noise generated withmachinery work such as tunnel drilling or that at the temporary
yard for crushed stone, we implemented noise-proof measuresand arranged working hours.

Waterpollution

Hydraulic oil was discharged to the drains of a factory. We
eliminated the oil using oil absorption material, and installed
polluted water treatment equipment for the water discharged tothe drains.

Vibration

In response to a complaint about the vibration caused by drilling,
we slowed down the speed of heavy machinery.

Dust

In response to a complaint about the dirt that came off fromconstruction vehicles on a public road, we cleaned the road andtires of the construction vehicles.

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 beenraising awareness of the importance of environment management and the prevention of environment-related accidents. Regarding the management of water resources, Taisei Corporation is
working to “prevent water pollution caused by construction wastewater, etc.” as a management priority. In FY2018, there were noenvironmental accidents or violations of environmental laws and regulations.

1,4-dioxane is a chemical substance that is commonly used as a solvent in the chemicalindustry, but it is now subject to water pollution regulations. However, since this substance does not decompose easily, the environmental burden and cost required for its
handling pose major issues. We searched for 1,4-dioxane-degrading bacterium from various environments, and found a new bacterium to degrade 1,4-dioxane effectively. We
have established a water treatment process using the degrading bacterium, and com-

Calculation Method & Standard
Classification into civil engineering and building construction (sites), offices (excluding development projects and others),
and factories
Scope 1: CO2 emissions associated with the combustion of fossil fuels
Scope 2: Indirect CO2 emissions associated with the use of electricity, steam, and chilled and hot water
Scope 3: CO2 emissions associated with the transport of construction waste off construction sites and the outward andreturn transport of soil from construction (off-site emissions)
CO2 emission coefficient: Calculated using the emission coefficient in accordance with the Act to Rationalize the Use of
Diesel, Heavy Oil, and Energy and the Act on Promotion of Global Warming Countermeasures. For offices, the actual
emission coefficient for FY2017 according to the electrical power company is used.
Electrical power: Calculated using the 2017 emission coefficient on the user end announced by the Japan Business
Federation (before reflecting the Kyoto credit), 0.495t-CO2/MWh.
City gas: Calculated using the standard calorific value of the gas supply company and the emission coefficient of the Act on
Promotion of Global Warming Countermeasures.
The annual quantities purchased and used by the offices and factories of the Taisei Group are calculated in monthly units.
Calculated for each company based on the Taisei Group environmental data manual. Consumption in a two-month period in
FY2018 is sampled at 190 construction sites to calculate the consumption per unit of construction turnover (basic unit).
Annual consumption is calculated by multiplying this basic unit by the construction turnover for the year. For civilengineering, this calculation is performed for each construction type.
The quantities of the main construction materials and other materials purchased directly through individual construction of
Taisei Corporation and joint venture construction for which Taisei Corporation is the representative. The same calculation
method applies to the consumption of concrete formworks and alternative formworks.

Construction by-products (waste and valuable resources) emitted at the sites of the Taisei Group individual construction
projects, joint venture construction for which Taisei Group is the representative, and factories owned by Taisei Group.

・ Organizations covered: the Taisei Group (Taisei Corporation, TAISEI ROTEC CORPORATION, Taisei-Yuraku Real Estate Co., Ltd., TAISEI U-LEC CO., LTD., TAISEI SETSUBI
CO., LTD., TAISEI HOUSING CORPORATION, SEIWA RENEWAL WORKS CO., LTD., and J-FAST Co., Ltd.), which are all within Japan only. Environmental data cover morethan 90% of the sales made by the entire Taisei Group.
・ Calculation standard: Calculated based on in-house standards and the Taisei Group’s environmental data calculation manual for the management of environmental
information, complying with the Act on the Rational Use of Energy, the Act on Promotion of Global Warming Measures, the Waste Disposal and Public Cleansing Act, and the
GHG Protocol, etc. In calculation of CO2 emissions, Taisei Corporation uses the value of the fuel consumption of the Japan Construction Mechanization Association, fromwhich the fat content is excluded. Energy-related: Fossil fuels (heavy oil, diesel, gasoline, kerosene), electrical power, city gas, and LPG consumption and their energyequivalent values.
