Formulation of New Environmental Policies

The Taisei Group endeavors to conserve and create the environment through our core business of the construction industry, and promotes environmental management aimed at realizing a sustainable society. Taisei Corporation operates an environmental management system (EMS) in compliance with ISO14001:2015, and we revised our "Environmental Policy"*1 for the first time in six years in order to promote environmental management better in line with our business by responding to changes in the situation surrounding the Company based on identified risks and opportunities. Based on the Environmental Policy, we work to reduce various environmental risks and impacts by setting specific environmental management targets (Taisei Agenda), and practice activities aimed at forming sustainable social infrastructure.

1 Formulated in July 2005. Final revision in April 2017.

KPIKey Performance Indicator

Taisei Corporation has set KPI targets in connection with important business-related environmental risks and opportunity creation in the FY2017 Taisei Agenda, and is making efforts to meet those targets.
We also continue to work on response to restoration and recovery in areas hit by major disasters as an item in our everyday management.
We recognize the close affinity between promotion of environmental management in the construction industry and efforts toward meeting the United Nations' sustainable development goals (SDGs) such as improving urban resilience. We have included the symbols for strongly related SDGs on the Taisei Agenda, which is posted throughout the Company.
