Research Institute for Global Change (RIGC)

Benefiting the whole world through research and development aimed at understanding the current status of global environmental change and predicting the future

To contribute to the resolution of global issues such as climate change, ocean acidification, and plastic pollution, we will lead international projects to conduct integrated research on oceans at all depths and on the close interactions of oceans with the atmosphere and land masses. We will apply the data obtained from this research to formulate both short-term seasonal predictions and mid- to long-term predictions covering centuries.

We will actively disseminate our research results through international frameworks such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement, the UNESCO Intergovernmental Oceanographic Commission (IOC), the Intergovernmental Panel on Climate Change (IPCC), and the Arctic Council (AC). We will contribute to the achievement of the United Nations Sustainable Development Goals (SDGs), in particular Goal 13 (climate action) and Goal 14 (life below water), as well as Japanese government policies.
