"This new relationship between Kimberly-Clark and Greenpeace will promote forest conservation, responsible forest management, and recycled fiber as far and wide as possible." Also by the end of 2011, Kimberly-Clark will eliminate the purchase of any fiber from the Canadian Boreal Forest that is not FSC certified. This forest is North America's largest old growth forest, providing habitat for threatened wildlife such as woodland caribou and a sanctuary for more than one billion migratory birds. It is also the largest terrestrial storehouse of carbon on the planet, storing the equivalent of 27 years worth of global greenhouse gas emissions. Furthermore, the revised standards reinforce Kimberly-Clark's long-standing ban on use of wood fiber from illegal sources; adds a preference for post-consumer recycled fiber; and supports expansion of recycling initiatives and the identification, mapping and protection of areas that have the potential to be designated as Endangered or High Conservation Value forests.
