EU Joins COP31 Geothermal Pledge Aiming for 193 GW of Power by 2050

The European Commission announced on 10 November 2026 that the European Union has joined the Global Geothermal Ambition 2050 at the COP31 talks in Antalya, Türkiye. The pledge was launched by the Turkish COP31 Presidency with the International Renewable Energy Agency. It aims to scale up global geothermal energy supply for power and heat to 12 times 2025 levels by 2050.

The announcement cites IRENA analysis indicating that total primary geothermal energy supply for heat and power could rise from around 2.5 EJ today to around 31 EJ by 2050. Global geothermal power capacity would increase from 15.6 GW in 2025 to 193 GW over the same period.

By our calculation, that capacity path would add 177.4 GW of geothermal power and would multiply 2025 capacity by 12.4 times, the same multiple as 31 EJ against 2.5 EJ.

Signatories commit to stronger policy frameworks and investment opportunities for geothermal energy. The announcement describes geothermal as a dispatchable renewable source that can complement variable wind and solar output and supply both electricity and heat. The pledge text also refers to research and development and to supply-chain work, together with international cooperation, and states that environmental and social responsibility should be respected.

COP31 is being held in Antalya from 9 to 20 November 2026. The Commission published the announcement during the first week of the conference.
