Since 2012, Colcom has supported Tree Pittsburgh with annual general operating support. This consistent funding has helped Tree Pittsburgh expand its operations, build capacity, and take on new leadership roles, including leading the formation of the Pittsburgh Canopy Alliance in 2020. The Alliance is a coalition of 20 environmental organizations dedicated to growing the tree canopy in Allegheny County and includes Western Pennsylvania Conservancy, Pittsburgh Parks Conservancy, Allegheny Land Trust, Student Conservation Association, Rachel Carson Trails Conservancy, UpstreamPGH, and Friends of the Riverfront.
Tree Pittsburgh recently spearheaded an effort to secure funding from the Inflation Reduction Act via a U.S. Forest Service grant. The request was granted, with $8M awarded to Tree Pittsburgh on behalf of the Pittsburgh Canopy Alliance and an additional $1M awarded to the City. These funds must be spent within five years and will go toward tree planting and maintenance, as well as work opportunities and education, and are designated for communities that experience high levels of pollution and economic distress.
