We are committed to addressing social challenges
with an eye toward realizing a sustainable society and enhancing corporate value.

Basic Policy

The Obayashi Basic Principles, consisting of the Obayashi Philosophy, Obayashi Code of Conduct, and Obayashi Three Pledges, apply to all officers and employees. We believe that our business activities themselves are the very practice of the Obayashi Basic Principles. We clearly define the Group's social responsibilities, taking account of the needs of our stakeholders and society. Then we work to solve social challenges. In June 2019, we established Obayashi Sustainability Vision 2050 (OSV2050). The Obayashi Group will work to achieve our vision for 2050, realizing the sustainability of the planet, society, and people.

Sustainability Promotion Framework

Management Policy for promoting sustainability is determined by the Board of Directors based on discussions at the Sustainability Committee and Director's Roundtable Meeting. On the business execution side, we have a system in place that consists of the Business Plan Committee commissioned by the president and under the jurisdiction of the Management Meeting, and expert committees in various sustainability-related fields that sit under the Business Plan Committee. These committees formulate and promote specific measures based on the management policies determined by the Board of Directors on the approach to the business portfolio, human resources and organizational strategy, and intellectual property strategy, among others. They also keep up-to-date with progress on the implementation of those measures and consult with the Board of Directors.
