Dan Lambe has committed nearly two decades of work to help solve some of the biggest issues facing people and the planet through trees. After being named CEO in 2022 after 19 years in leadership roles at the Arbor Day Foundation, Lambe launched an initiative to accelerate the nonprofit’s impact by planting 500 million trees with a focus on forests and neighborhoods with the greatest need. The ambitious goal, set to replicate the number of trees planted in the Foundation’s first 50 years in only five years, has helped spur remarkable growth within the organization and expanded the Foundation’s global reach. Lambe’s leadership is rooted in three guiding principles, including supporting a quality team, bringing an increased focus to planting trees, and instilling a belief that the Foundation’s work can make a lasting difference.

Lambe is a trusted thought leader in the sustainable forestry space, and he regularly speaks at conferences hosted by the United Nations, Sustainable Brands, the U.S. Chamber of Commerce and other high-profile industry events where trees and climate intersect. Lambe is also frequently used as a resource for top news outlets and has been featured on The Weather Channel, CNN, The Washington Post, Associated Press, TIME, Forbes, Inc.
