The documentclass europecv is outdated and does not contain the latest euroPass, here an example in english.
The latest update of the package is from 2014 here so an alternative solution must exist.
Instructions are here about the format.
I sent a kind request to the author to update the package as an encrypted and signed email as the author wants.
