SEMINAR TIMETABLEPromoting Use of GOSAT Data for Climate Science Outreach and Business Applications

As GOSAT-GW successfully launched in June 2025, NIES and MOEJ are promoting climate science outreach both domestically and internationally, while also encouraging the utilization of GOSAT-GW data by the private sector.
We integrate the latest scientific knowledge and observational data - including high-spatial-resolution greenhouse gas (GHG) data provided by GOSAT-GW, long-term satellite data from GOSAT and GOSAT-2 dating back to 2009, and precise in-situ measurements collected from ground sites, ships, and aircraft. Our aim is to provide this information not only to researchers but also to domestic and international policymakers, local governments, and the private sector through the Japan GHG Center (provisional name), thereby promoting global decarbonization efforts.
This seminar provides an overview of the current status of GOSAT-GW and the Japan GHG Center, as well as prospects for private-sector's use of the GOSAT data.

At this seminar, we welcomed speakers from domestic and international research institutions, UN agencies, space organizations, and private companies to present the achievements of Japan’s GOSAT series satellites and prospects for utilizing satellite data to promote decarbonization efforts. In the latest status report on GOSAT-GW, launched in June 2025, we analyzed data obtained through its Focus Mode observation and, for the first time publicly, reported concentrations of carbon dioxide, methane, and nitrogen dioxide. Furthermore, we introduced initiatives for leveraging satellite data to reduce greenhouse gas emissions, including collaboration between Japan and international organizations, and discussed prospects and effectiveness in business fields such as insurance and finance. In addition, we presented the preparation status of an information center (tentatively named the Japan GHG Center) that will disseminate the latest observation data and scientific insights worldwide. Finally, we introduced Japan’s efforts to establish frameworks for next-generation education in climate science and greenhouse gas studies.
