This page contains additional information related to the Green Web Foundation provider verification criteria and process. These FAQs are a supplement to What disclosures do you accept for verification which you should read first to familiarise yourself with the current verification criteria.
For the purposes of verification, we consider the following forms of energy to be fossil-free energy sources:
- Solar power (photovoltaic and solar thermal)
- Wind power (onshore and offshore)
- Geothermal energy
- Ocean energy (tidal, wave, and ocean thermal energy conversion)
- Hydropower
- Nuclear energy
We have arrived at this list of energy sources after reviewing existing accepted clean energy standards in particular the 24-7 Carbon-Free Coalition (24-7 CFC) Technical Standard.
