The International Energy Agency Geothermal Implementing Agreement (IEA-GIA), or IEA Geothermal, provides an important framework for wide-ranging international cooperation in geothermal R&D.  Efforts concentrate on encouraging, supporting and advancing the sustainable development and use of geothermal energy worldwide both for power generation and direct-heat applications.


To promote the sustainable utilization of geothermal energy worldwide by improving existing and developing new technologies. Efforts focus on facilitating the transfer of know-how, providing high quality information and widely communicating geothermal energy’s strategic, economic and environmental benefits. The goal is to render exploitable our vast and widespread global geothermal resources, to contribute to the mitigation of climate change.
