I have been researching picture frame mouldings and stretcher bars that do not result in environmental damage. The plot thickens the more I learn about the framing / moulding industry. There is an excellent resource I found that discussed woods to avoid: http://www.rainforestrelief.org/documents/Guidelines.pdf
One company I have found is very in tune with this issue: Framerica moulding seems to be one of the most eco-friendly moulding companies. Here is an excerpt from the Decor Article on Green Framing Products:
Framerica’s products have earned Environmentally Preferred Product (EPP) certification from the Composite Panel Association of wood manufacturers, and BonanzaWood saves deforestation from solid wood and the oil consumption attributed to plastics. Framerica has used BonanzaWood as the primary core for its mouldings for more than 10 years. BonanzaWood contributes to absolutely zero deforestation, in many instances utilizing wood waste from post-consumer products that would otherwise be destined for landfills.
I must also point out that Omega moulding has been very helpful with my inquiries about moulding wood, and referred me to this website: UNEP.
I am still doing research on some of their mouldings I have been using to see if they are FSC certified.
