ESG Initiatives

From the view point of ESG (Environment, Social, Governance),

Supporting Global Initiatives

In order to realize a sustainable society, we are not only implementing the Obayashi Basic Principles but we are engaging in many activities aimed at meeting the expectations and demands of society, based on various guidelines.

Participation in the United Nations Global Compact

Obayashi joined the UN Global Compact(*1) in August 2013. The UN Global Compact supports ten principles relating to areas of human rights, labor, environment, and anti-corruption. We will promote our business activities with a high sense of responsibility and global perspective in order to promote responsible business to contribute to the creation of a sustainable society.

*1 UN Global Compact
The Compact was advocated by then UN Secretary-General Kofi Annan in 1999, then officially launched in 2000 at UN Headquarters in New York. It is an international initiative to achieve healthy globalization and a sustainable society. It calls for the rollout of corporate strategies and activities that comply with and put into practice ten principles in four areas: human rights, labor, environment and anti-corruption

Initiatives for Sustainable Development Goals (SDGs)

We link SDG's goals(*2) to our business in accordance with the Obayashi Basic Principles. We will continue making contributions through our business to overcome the ESG challenges and achieve the goals of the SDGs.

*2 Sustainable Development Goals
The UN Sustainable Development Summit was held at UN Headquarters in New York City in September 2015. The outcome was "Transforming our World: the 2030 Agenda for Sustainable Development," a document adopted by the more than 150 heads of UN member states in attendance. The plan of action for people, planet, and prosperity sets out 17 goals with 169 specific targets as the Sustainable Development Goals (SDGs). It calls on enterprises to make proactive efforts to achieve these.
