What Japan Center for a Sustainable Environment and Society does

Japan Center for a Sustainable Environment and Society (JACSES, legally \u300c\u74b0\u5883\u30fb\u6301\u7d9a\u793e\u4f1a\u300d\u7814\u7a76\u30bb\u30f3\u30bf\u30fc, a Specified Non-Profit Corporation under Japanese law) is a Tokyo-based policy research and advocacy NGO founded in 1993. The organization conducts environmental policy research and public advocacy across nine program areas: development and aid, tax and fiscal policy, climate change, SDGs/SCP, NGO capacity building, fluorocarbons, globalization, environmental capacity, and water privatization. Its primary outputs are policy proposal reports, briefing papers, two monthly email newsletters (Climate Policy Express+ and the JACSES Mail Magazine), and published books such as "Gigaton Gap: Climate Change and International Negotiations." JACSES participates directly in international climate negotiations including UNFCCC COP meetings (notably COP30 in Bel\u00e9m) and engages in regular government-NGO dialogue processes with the Japanese Ministry of Finance and other ministries.

JACSES does not develop commercial technology products; its core technology is policy research, report authorship, and direct participation in policy processes. The organization is led by Representative Director Furusawa Kosuke (a Koku Gakuin University economics professor), Secretary General Adachi Jiro, Climate Change Program Leader and Deputy Secretary General Endo Risa, Editor-in-Chief Onoda Shinji, and Deputy Editor Kishi Shunsuke. Its audience includes Japanese government agencies, policymakers, academic researchers, civil society organizations, students, and members of the public interested in climate and environmental policy.

The business model is non-commercial: revenue is generated through supporter/membership fees, donations, and publication sales (e.g., the Gigaton Gap book at 1,600 JPY inclusive), supplemented by likely foundation and government grants for specific policy projects. Distribution is conducted via a direct-to-consumer publication storefront on jacses.org, owned email newsletters on the Mail2 platform, an Instagram channel (@jacses_climate_sdgs), press releases, and direct participation in international policy forums. The organization has no parent company, no venture capital or private equity backing, and is governed independently by a board of directors.
