Our Mission

This project aims to build a scientific platform for understanding and reducing greenhouse gas emissions through strengthened collaboration with domestic and international research and government institutions, by integrating insights from their respective activities.

About us
Climate Crisis
See More
We introduce the urgent need for action regarding global warming and its impacts. Learn about the importance of reducing greenhouse gases and the measures the world needs to take.
Paris Agreement
See More
We introduce the importance of international cooperation to limit temperature rise to 1.5°C and the efforts of each country based on the Paris Agreement.
Global Stocktake
See More
This is an important process to review the progress of each country's emission reduction targets based on the UN Framework Convention on Climate Change (UNFCCC) and to enhance the effectiveness of global climate action.
GOSAT-series Satellite Observation
See More
'Top-down estimation' by observing greenhouse gas emissions from satellites enables rapid emission assessment and verification of reduction measures.
