You can not get one for Spain.
I think it will be OK in Spain with the French one for infomation on which band.
Quote for Spain site:
"Can I drive with my badge from another country in restricted areas within Spain?
Yes. You can check the equivalence between the classifications of the different countries. In this way you will be able to know the equivalent Spanish emblem of your vehicle, knowing what traffic restrictions may affect you, and being able to drive on our roads with the emblem of your country
If my vehicle has a foreign license plate, can I obtain a Spanish environmental label?
No, but if your vehicle comes from a country with environmental certification (Germany, Austria, Denmark, France), you can check the equivalent of your badge in Spain, knowing what traffic restrictions may affect you, being able to drive with your country's badge ."
