Established within IGES in 1999, TSU supports the activities of the Intergovernmental Panel on Climate Change (IPCC) Task Force on National Greenhouse Gas Inventories (TFI).

Asia-Pacific Network for Global Change Research (APN)

The APN is an inter-governmental network of countries (currently 22 member countries) whose mission is to foster global change research in the Asia-Pacific region, increase developing country participation in that research, and strengthen interactions between the scientific community and policy-makers. In order to optimise its work, the APN Secretariat came under the administrative umbrella of IGES in April 2004, although the APN’s Intergovernmental Meeting (IGM) continues to be its policy and decision-making body.



Japanese Center for International Studies in Ecology (IGES-JISE)

JISE carries out practical surveys and research to restore, regenerate and create forestry and vegetation from regional to global levels to move towards the establishment of a sustainable society from the perspective of plant ecology. JISE also promotes training in environmental and ecological studies, and collects and disseminates related information. JISE was integrated into IGES in April 2007.


IPBES Technical Support Unit for the Assessment of Invasive Alien Species (IPBES-TSU-IAS)

IGES has been hosting the technical support unit for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) thematic assessment of invasive alien species and their control (TSU-IAS) since February 2019 at the Tokyo Sustainability Forum (TSF). IGES had also hosted the technical support unit for the IPBES Regional Assessment for Asia and the Pacific (TSU-AP) since 2015.
These TSUs have functioned as extensions of the IPBES secretariat that is headquartered in Bonn, Germany. The purpose of the TSUs has been to support and assist in the coordination of these two IPBES assessments, including the drafting of the respective IPBES assessment reports.
