Sustainable Forestry Initiative billboards
If you’ve walked, biked, riden, or driven around the East side of downtown lately, you’ve seen the Sustainable Forestry Initiative billboards.
The SFI encourages responsible forest and land management. Wood officially labeled by the SFI is either Chain of Custody [all wood harvesting and manufacturing processes are confirmed to meet the sustainable standards] certified or 100% Certified Content [product comes entirely from a SFI qualified forest] certified.
Supporting and choosing products that have been SFI certified is an environmental move that helps reduce clear cutting and other damaging forestry practices.

I would strongly encourage people to purchase FSC Certified lumber NOT SFI. SFI was developed and funded by timber industry representatives in 1994 in response to FSC (the Forest Stewardship Council) which is a non-partisan organization based on scientific research about healthy sustainable forestry practices and established in 1993. Not until last year was the SFI board of directors fully independent from interested parties, and they brag about that fact in this press release. http://www.sfiprogram.org/miscPDFs/SFI%20Independence%20Ad.pdf
