In order to achieve its objectives EFDA conducts the following group of activities:
* Collective use of JET, the world's largest fusion experiment
* Reinforced coordination of fusion physics and technology research and development in EU laboratories. 
* Training and carrier development of researchers, promoting links to universities and carrying out support actions for the benefit of the fusion programme. 
* EU contributions to international collaborations outside F4E
EFDA coordinates a range of activities to be carried out by the Associations in 7 key physics and technology areas. The implementation of these activities benefits from structures so called Task Forces and Topical Groups. The European Task Forces on [https://web.archive.org/web/20091222223222/http://www.efda.org/about_efda/activities-plasma_wall_interaction.htm Plasma Wall Interaction] (PWI) and on [https://web.archive.org/web/20091222223205/http://www.efda.org/about_efda/activities-integrated_tokamak_modelling.htm Integrated Tokamak Modelling] (ITM) set up respectively in 2002 and 2003. To strengthen the co-ordination in other key areas five Topical Groups have been set up in 2008: on [https://web.archive.org/web/20090419230108/http://www.efda.org/about_efda/activities-fusion_materials.htm Fusion Materials Development], [https://web.archive.org/web/20091222223153/http://www.efda.org/about_efda/activities-diagnostics.htm Diagnostics], [https://web.archive.org/web/20091222223159/http://www.efda.org/about_efda/activities-heating_and_current_drive.htm Heating and Current Drive], [https://web.archive.org/web/20091222223242/http://www.efda.org/about_efda/activities-transport.htm Transport] and [https://web.archive.org/web/20091222223217/http://www.efda.org/about_efda/activities-magnetohydrodinamics.htm Plasma Stability and Control].
