Here's Moe's answer: If you are one of the leading companies in the United States that sends out bulk mail, and repetitively sends out bulk mail, the envelopes will sometimes say Made From Recycled Paper, and most people say that is a positive. The electricity that is used to recycle paper is a cost in dollars, and it takes coal to make electricity, which is a finite resource and must be continually mined. If you're talking hydroelectric power, that means damming up rivers to the point that eventually the river becomes a creek. The telephone company that bugs me to sign up for their service will buy the cheaper envelope, even if it is .5 cents cheaper per envelope. Where the wood came from is not a point of interest to a Wall Street or NASDAQ company. Then again, they might buy the recycled envelopes that have that recycled logo to impress people. The down side to any industry is that accountants don't go to the same restaurants as people who drive earth movers or have degrees in forestry. Yuk, yuk, yuk.
