This label is made by the the producer, Stjörnuegg, and is not a verified certification. It illustrates the producers statement that no GMO is used to feed the hens laying the eggs. 

The only verified certification about no GMO in production is the Tún organic product label. 

Though this label is likely intended to inform consumers it is only a statement by the producer and up to the buyer to decide the integrity of the statement. 

Unverified labels of this kind are likely to confuse the customer and dilute the value of proper certified labels where statements have to be backed by research, rules and verified by third party.
