To be perfectly honest, it’s not about us. It’s about businesses recognizing that industry and ecology are inherently connected. It’s about realizing the positive effects of connecting businesses, consumers and nonprofits through philanthropy. And it’s about understanding that the true cost of doing business can be mitigated by a simple pledge to the planet.

Since 2002, 1% for the Planet has inspired members of the business community to contribute 1% of sales to environmental groups around the world. In return, this growing alliance of companies is given the opportunity not only to see their self-worth rise, but their net worth climb as well.
