Good day

I am working on projects in Estonia and we are trying to achieve the requirement for Opt 2 of this credit by choosing 5 materials from 3 different manufacturers.

During my research I stumbled upon many eligible materials, however those are mostly used in North American region.

Does anyone have any clue which materials can we choose in Eurpean Region? A database or certain materials you have used would be highly appreciated.

Thanks in advance!
