For 30 years, WHC has been promoting and certifying ecological stewardship action on corporate lands through partnerships and education. Since only 10-15% of the world's land surface is protected, private lands provide an essential opportunity for restoring and protecting biodiversity. As the only international conservation NGO focused exclusively on the private sector, WHC provides a framework for voluntary conservation action on a wide variety of corporate lands. WHC's corporate members represent some of the leading national and multinational corporations seeking to support sustainable ecosystems and the communities that surround them. These efforts have resulted in more than 1,000 certified programs across 48 states, Washington, D.C., Puerto Rico, and 29 countries.
