We are a non-profit 501(c)(3) organization based in Seattle. Our mission is to bring the wide range of environmental benefits of trees to our cities and towns in America. We seek to make American cities greener and healthier by enabling urban tree-planting and preservation projects to earn carbon credits to generate much-needed funding for our declining urban forests.
We are supported by generous grants from:
- The Bullitt Foundation
- Herman P. and Sophia Taubman Foundation
- Laird Norton Family Foundation
- McKibben Merner Family Fund
- Beardsley Family Foundation
Our progress is made possible by hundreds of hours of work by dozens of longtime urban forest professionals. Many of those are listed below as part of our Protocol Drafting Group and our Board of Advisors. Of particular note are the technical assistance and scientific contributions of Dr. Gordon Smith, Dr. E. Greg McPherson, Scott Maco, and Andy Trotter.
Mark is the Executive Director of City Forest Credits. Mark is a lawyer and business person and has been active in urban forestry for many years. He drafted the first conservation easement for the City of Seattle Heritage Tree Program over 25 years ago. He received a Founder’s Award from a tree preservation group in Seattle for his legal work in many tree cases. For the ten years prior to founding this non-profit organization, Mark managed a business and co-founded a website. He was a Morehead Scholar at UNC-Chapel Hill and has a Ph.D. and law degree from Harvard.
Mark and several members of the drafting group below served on the work group at the Climate Action Reserve in 2013-14 that developed an urban forest carbon protocol.
Dr. Gordon Smith
Dr. Gordon Smith has made critical contributions to our development of the first-ever City Forest Tree Preservation Protocol. Dr. Smith brings many years of experience in carbon accounting and has consulted with state, federal, private sector, and non-profit organizations on a range of issues relating to GHG standards, accounting, and implementation.
Dr. Smith was an early participant in GHG credit markets, and has extensive expertise across the entire spectrum of mitigating GHG emissions including making land uses more productive, managing land use change, modeling emission benefits, standards development for GHG accounting, project development, project and methodology validation and verification, and verifier accreditation.
Dr. Smith is a member of the editorial board of the journal Carbon Management; member of the Greenhouse Gas Management Institute advisory committee; accredited expert with the Verified Carbon Standard (VCS) in afforestation/deforestation, improved forest management, avoided deforestation (REDD), and agricultural land management; and; member of the AFOLU Technical Committee of the American Carbon Registry (ACR). Formerly, he was Carbon Development Director for the REDD project developer Wildlife Works. Dr. Smith is the Technical Lead for the Sustainable Lands component of the USAID Climate Economic Analysis for Development, Investment and Resilience (CEADIR) project.
