The work of the IPCC is organized in three Working Groups and a Task Force; Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. The Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals of greenhouse gases.
The IPCC does set up different Task Groups to address specific issues. At present, the IPCC has four Task Groups:

Task Group on Data Support for Climate Change Assessments (TG-Data)

At its 47th Session (Paris, France, 13-16 March 2018), the Panel decided to rename the Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA) to "Task Group on Data Support for Climate Change Assessments (TG-Data)". The Panel also adopted terms of reference for the TG-Data and guidance for the core functions of the Data Distribution Centre (DDC)


Ad-hoc Task Group on Financial Stability (ATG-Finance)

The Task Group was established by the 45th Session of the IPCC (Guadalajara, Mexico, 28-31 March 2017). The ATG–Finance’s purpose is to propose, to the Panel, funding options and their implications in order to provide predictable, sustainable and adequate means for a smooth implementation of the IPCC’s work programme. Its mandate also includes identifying matters affecting IPCC’s financial stability. Its mandate has been extended twice, by the Panel during its 46th and 47th Sessions.
The ATG-Finance will report on progress to the 48th Session of the IPCC in October 2018.


IPCC Gender Task Group

The IPCC, at its 47th Session (France, Paris, 13-16 March 2018) decided to establish a task group to develop a framework of goals and actions to improve gender balance and address gender-related issues within the IPCC. The Task Group on gender will report back to the Panel’s 49th Session scheduled in May 2019.


Task Group on the Organisation of the Future Work of the IPCC in light of the Global Stocktake

At its 43rd Session (Nairobi, Kenya, 11 – 13 April 2016), the IPCC requested the Secretariat to prepare proposals for aligning the work of the IPCC during its Seventh Assessment Report (AR7) with the needs of the global stocktake under the Paris Agreement. At its 46th Session (Montreal, Canada, 6 – 10 September 2017) the Panel established a Task Group on the alignment of the IPCC cycles and the global stocktake. During the 47th Session (France, Paris, 13-16 March 2018) the Panel adopted the Task Group’s terms of reference and renamed it Task Group on the organization of the future work of the IPCC in light of the global stocktake
