What are the standards for "green" Christmas trees and where can I purchase one in the Silicon Valley?

To pass muster, a farm must be inspected to ensure that it meets certain standards for managing wetlands, nutrients and pests. Water and soil conservation measures are reviewed, and biodiversity and worker safety are also considered.

Looks like a scam to get everybody to pay one grower who made up some green coalition a little cash to certify their farm .

Just get you tree from some group that sells them and donates part of the proceeds to charity it may not be all that green but it is in the spirit of Christmas.

Buy a fake one if your that worried about it. Plus you won't kill a tree.
