Despite evidence that urban trees offer a diverse range of benefits – from improving air and water quality to reducing energy costs, improving human health, and even storing carbon – they are disappearing at an alarming rate from cities across the U.S.
A recent paper by two Forest Service scientists reports that 36 millions trees are lost each year in U.S. metropolitan areas. The reasons are largely financial, with many municipalities unable to find enough money to finance green projects. It’s been reported there’s a growing recognition of the inequity of tree-canopy distribution in U.S cities, with vast cover in wealthy areas and far fewer trees in disadvantaged neighbourhoods. Add to this the difficulties posed by drought and increased temperatures due to climate change, and it’s clear to see why urban trees are suffering.
However, good news is on the horizon. To help find more funding for urban trees, some local governments, including Austin, Texas, and King County, Washington are running pilot projects with a non-profit organisation called City Forest Credits (CFC) in Seattle. The projects are generating funding for city tree canopies from private companies and individuals who wish to offset their carbon emissions. These companies and individuals buy credits for tree planting or preservation, contributing to greener urban environments.
The credits generated from these projects “are specifically catered to the urban environment and the unique challenges and possibilities there, so they differ from traditional carbon credits,” said Ian Leahy, a member of the CFC protocol board, and Director of Urban Forestry Programs at American Forests – a non-profit conservation group.
Zach Baumer, Climate Program Manager for the City of Austin, and fellow member of the CFC board, said, “I think the work is innovative and potentially game-changing. To harness the market to create environmental benefits in cities is a great thing.”
To be eligible for new carbon credits, city tree projects must follow official procedures for urban forests. These include rules covering specific factors like the location and duration of a project, and how the carbon will be quantified.
