50 Million Tree Pledge

Working with the Arbor Day Foundation and the US Forest Service, our Foundation is underwriting the planting of 50 million trees over 50 years in National Forests around the USA, Canada, the United Kingdom and Germany.

A Colorado Story

Over the course of three years, we've funded the planting of 860,000 trees in Pike National Forest, with 20,000 more planned for 2015. Pike National Forest was severely damaged by fire in 2002, impacting the health of the South Platte watershed, which provides more than 60 percent of Denver's drinking water.

What Can 10 Million Trees Do?

According to the Arbor Day Foundation, 10 million trees can absorb more than 10 million pounds of carbon, produce oxygen for up to 40 million people per day and lift as much as a billion gallons of water out of the ground and into the air.
