I happened to notice a new brand of tissues at Publix yesterday. They're made by a company called Scotties. The best part is that for every tree they use, they plant 3. The company uses trees that are certified by the Sustainable Forestry Initiative and is somehow ambiguously linked to the Renewable Forest Project.
That's 10x better than using recycled tissues. They're not that expensive (they cost about 0.75¢) when compared to something like Publix Greenwise (costing about 0.70¢).
