A family of four’s annual toilet paper use generates about the same amount of carbon as cutting down 27 trees or flying on a jet from Toronto to Vancouver. Those are the kind of statistics that might make you want to sit down, on the throne, perhaps, with a new appreciation of what we’re flushing away. The numbers come from the New York-based Natural Resources Defense Council. The council’s annual ranking of toilet paper released Friday heaps scorn on those companies, such as consumer goods giant Procter & Gamble Corp., that shun recycled paper in their top-selling products, such as Charmin. The council gives mixed praise to competitor Kimberly-Clark Corp. for finally offering environmental tissue — Scott Essential Standard Roll — to the residential market, while retaining market share in offending tissues, such as Cottonelle. …“The toilet paper we buy is a climate decision,” Vinyard said.
