City Forest Credits - Urban Forestry Carbon Registry
United States · 2015 · City Forest Credits
City Forest Credits has enabled a structural shift in how urban forestry is financed by translating trees into measurable carbon credits that can unlock dedicated climate finance. This has allowed cities and nonprofit organizations to fund tree planting and long-term preservation that would otherwise depend entirely on constrained public budgets. The system has helped integrate urban canopy expansion and preservation into formal climate strategies, linking carbon accounting with local resilience priorities such as heat mitigation, stormwater management, air quality improvement, and public health. Importantly, it keeps climate investments geographically embedded, ensuring benefits are directly visible and experienced by urban residents.
Highlight
An ICROA-endorsed urban forestry carbon registry that enables cities to fund tree planting and preservation through verified carbon credits and measurable local environmental benefits.
Extended description
City Forest Credits (CFC) was established in 2015 to address a structural gap in climate finance: urban forests were widely recognized for their environmental and social value but were largely excluded from mainstream carbon markets. Traditional offset systems focused on large-scale rural forestry, renewable energy, or industrial emissions reduction projects, leaving cities without dedicated financial mechanisms to support urban tree planting and long-term forest preservation.
To address this, City Forest Credits developed a dedicated carbon registry and set of urban forestry protocols that enable municipalities, nonprofits, conservation organizations, utilities, and private landowners to generate verified carbon credits from urban tree projects. The organization operates as a nonprofit standards body responsible for methodology development, project registration, independent verification oversight, and credit issuance.
Projects fall into two main categories: urban afforestation/reforestation and long-term urban forest preservation. These projects must meet strict additionality, monitoring, and permanence requirements, with preservation commitments typically extending 40–100 years. Credits are issued only after third-party verification confirms compliance with approved methodologies.
A defining feature of the system is the Carbon+ Credits™ framework. Each credit represents one verified metric ton of CO₂ equivalent (tCO₂e), but also reports additional ecosystem services including stormwater interception, air pollutant removal, energy savings from reduced heating and cooling needs, and biodiversity co-benefits. This reflects a broader systems approach where urban trees are treated as multi-functional infrastructure rather than purely carbon sinks.
A key quality signal for the program is its endorsement by ICROA (International Carbon Reduction and Offset Alliance). ICROA is a globally recognized accreditation body that evaluates carbon standards based on governance, transparency, environmental integrity, and verification rigor.
Operationally, projects are implemented through partnerships between local governments, NGOs, landowners, and technical forestry experts. Credit issuance is contingent on verified carbon accounting and long-term maintenance obligations. The registry ensures transparency by publicly listing projects and maintaining auditable records of issued credits.
The system embeds urban forestry directly into climate finance mechanisms, enabling cities and Project Operators to fund tree planting and forest preservation through private-sector climate investment rather than relying solely on public budgets. This supports integrated urban resilience strategies addressing heat stress, flooding, air pollution, and environmental inequality.
Since 2023–2024, the voluntary carbon market has undergone increased scrutiny following broader concerns about credit integrity across some offset categories. While these concerns have not been directed specifically at City Forest Credits, they have contributed to more cautious corporate purchasing behavior and slowed project development.
Demonstrated metrics
City Forest Credits Carbon+ Credits™ quantify both carbon and ecosystem services across urban forestry projects:
Carbon sequestration and storage (tCO₂e per credit)
Stormwater interception and runoff reduction (m³/year)
Air pollutant removal (tons/year)
Energy savings from urban cooling effects (kWh/year)
Urban canopy expansion and forest preservation area (acres)
Long-term permanence commitments (40–100 years for preservation projects)
Projects are implemented in and around multiple U.S. cities including Austin, King County, Chicago, Des Moines, Minneapolis, and Atlanta. Credit pricing has typically ranged in voluntary markets around USD 22–45 per tCO₂e depending on project type, co-benefits, and verification conditions.

Implementation location & date
United States; projects implemented across multiple cities and metropolitan regions. CFC was established in 2015 and continues to register and issue credits for urban tree planting and forest preservation projects.
Similar cases elsewhere
Comparable carbon-finance models operate through Plan Vivo projects in Latin America, Africa and Asia-Pacific, although these generally focus on community-led forestry and restoration rather than CFC's urban-specific registry model.
