TFI Technical Support Unit


The Technical Support Unit (TSU) for TFI is based at the Institute for Global Environmental Strategies (IGES) in Japan. The Unit is supported by the Government of Japan. The TSU provides scientific, technical and organisational support to the TFI under the overall supervision of the Task Force Bureau (TFB).


The establishment of TSU at IGES was completed in September 1999 with substantial co-operation amongst the IPCC, OECD, IEA, Government of Japan and other related institutions. Currently, seven staff members are working in the TSU at IGES.




An intern programme was launched in 2003 to provide opportunity to young researchers/scientists to familiarise themselves with the IPCC methodologies for national GHG inventories through applied studies on the science relevant to specific sector(s). However, for the fiscal year 1 July 2020 – 30 June 2021 the internship programme is not active.
