Is there any legal status attached to the label UNESCO Global Geopark?

No, “UNESCO Global Geopark” is not a legislative designation – though the defining geological heritage sites within a UNESCO Global Geopark must be protected under indigenous, local, regional or national legislation as appropriate. UNESCO Global Geopark status does not imply restrictions on any economic activity inside a UNESCO Global Geopark where that activity complies with indigenous, local, regional and/or national legislation.
