The Geothermal criteria sets out what geothermal projects are applicable for certification under the Climate Bonds Standard

The potential of current geothermally-active regions is estimated to be able to provide roughly 10% of world primary energy consumption.

Additionally, Enhanced Geothermal Systems (EGS) technologies are being developed that will expand geothermal’s geographical range, and hence increase this potential by an order of magnitude.

Geothermal looks set to be a huge source of clean energy for the future.

However, in some instances Geothermal can also be a source of emissions. Some geothermal plants can actually generate higher direct greenhouse gas emissions than fossil fuel equivalents; drilling through some rock types can lead to fugitive GHG emissions.

The Geothermal criteria addresses this issue with the emission threshold that projects must meet if they are to be certified. 


1. New and existing geothermal projects with direct emissions of less than 100gCO2/kWh

2. Geothermal projects with mitigation technologies that will render the non-condensable gas releases to the atmosphere negligible

3. Geothermal projects that have been reviewed and registered under the Clean Development Mechanism



Geothermal Expert Advisory Committee - provided input as technical advisors, however they do not formally endorse the criteria that have been developed

Climate Bonds Standard: Sector Criteria Process

Each sector-specific eligibility criteria are developed along a set process. This ensures we create robust science-backed criteria that are usable in the market:

Sector criteria are currently available for Solar Energy, Wind Energy, Geothermal Energy, Low Carbon Buildings, Water Infrastucture, Low Carbon Transport and Marine Renewable Energy.

Soon to be available are criteria for Hydropower and Forestry. Work is ongoing on Waste Management, Bioenergy, Land Conservation & Restoration and Land Use.
