Switzerland the first country to mandate full disclosure

With full disclosure all electricity production sites are forced to issue a Guarantee of Origin for every MWh of production, regardless of the type of power station that has produced it.  While some criteria exists (such as the size of the power station) RECS International is very supportive of this decision and encourages other national bodies to follow suit.

Full disclosure eliminates many questions around how supply companies should disclose their fuel-mix to end-consumers.  While in some countries renewable electricity is regulated as being from a Guarantee of Origin, very few countries have said how to calculate the non-renewable portion of the mix.
