ECO20® Made with solar energy

Make your products make a difference with respect to competitors thanks to a new quality standar.

The ECO20® seal counts on the certification of an ENAC accredited entity to certify energy management systems or environmental management and it guarantees that the energy used in the manufacturing process has 100% solar origin, with no environmentally unfriendly greenhouse gas emissions.


ECO20® is based in Warranties of Origin, an instrument issued by the Spanish National Commission for Markets and Concurrence (CNMC) which certifies that a determined amount of electric energy has been obtained from the sun in a determined period of time. This warranty system allows any industry to certify that the origin of its consumption comes from solar sources.
