Improved Forest Management

The King County Forest Carbon Program supports the permanent protection of threatened forests in both rural and more suburban parts of the county across a set of dispersed properties including some islands in Puget Sound. As of 2020, the project has acquired 96 parcels totaling 514 hectares and will continue to add more as the project progresses. Run by the King County Department of Natural Resources and Parks (DNRP), this project is using carbon financing to accelerate the purchase of additional parcels of land that are at risk of clearing for rural residential development or commercial timber harvest.

Pachama's project evaluation criteriaPachama rigorously evaluates every project listed on our marketplace to ensure that we're surfacing only the highest quality projects. Our Evaluation Criteria includes a series of checks that every project must pass as well as a number of informative insights on project quality. You can see a preview of these checks below.



The project's emissions reductions have been conservatively quantified

  • Baseline

    The reported baseline emissions are less than or equal to Pachama's observed baseline emissions. There are some variations based on project type.

  • Past Project Emissions

    The reported emissions inside the project area are greater than or equal to Pachama's observed emissions.

  • Carbon Inventory

    The project estimated their carbon stocks using a field inventory or remote sensing approach that was statistically representative of the project area, and their carbon stock estimate included a confidence interval and had <15% standard error.



Emissions reductions would not have occurred without the incentive of carbon credits

  • Project Boundary

    The boundary has not been artificially manipulated to increase crediting.

  • Financial and Legal Additionality

    There was no funding for carbon project activities in the 10 years prior to the project start date, and there were no legal requirements for emissions reductions or removals.

  • Improved Forest Management Projects Only

    Forest Maturity

    The crediting period must extend at least 25% beyond the age of economic maturity for at least half of the project area.

  • Reforestation Projects Only

    Forest Cover

    There must be no deforestation within the project area and existing forest cover must be less than 10% in the 10 years prior to project start date.



The project delivers a long-lasting climate impact ensured by continuous monitoring and reporting

  • Recent Project Emissions

    Pachama observed project emissions are less than the leakage-adjusted baseline meaning the project continues to provide a net climate benefit since their last credit issuance.

  • Fire Risk

  • Other Natural Risks

  • Buffer Pool



The project hasn't simply moved deforestation from one place to another, producing no net climate benefit

  • Leakage Summary

    Pachama currently examines and summarizes leakage calculations from registry-verified documents. Accounting for leakage is an inherently complex challenge with a range of methodologies. Pachama is using satellite observations to develop a consistent and easy-to-understand approach to quantifying leakage.


Beyond Carbon

The project causes no net harm and delivers biodiversity and community benefits

  • Free, Prior, Informed Consent

    The project sufficiently demonstrated proper community engagement and consultation, and a grievance and redress mechanism is in place.

  • Certifications

  • Forest Management

  • Reforestation Projects Only

    Ecological Impacts

    For reforestation projects, the forest composition must be a majority native species, there must be at least 5 different species planted, and the species assemblage and density should be similar to what would typically be found in the local ecoregion.


Tech-verified evaluationEvery forest project listed on the Pachama Marketplace must align with our Evaluation Criteria to ensure we're surfacing only the highest quality projects. To assess a forest project, Pachama uses remote sensing to review a variety of factors including forest cover loss in and around the project area. This project passes our emissions quality checks because the reported emissions are in line with what Pachama observed.

Contains modified data from Hansen Global Forest Change v1.9 (2001-2021).

Project story
Providing clean air, water, and public parks by protecting existing forests

Located near Seattle, Washington in the Pacific Northwest, this area is known for its temperate rainforests that include some of the largest trees in the world, yet is also the most populous county in the state with over 2.23 million residents. Most forests in King County have been heavily cut for timber production and regenerated one or more times since the late 1800s. Additionally, over the past several decades, increased local housing demand has expanded into rural areas putting pressure on nearby forests. By conserving these forests, the project will not only provide net emissions reductions but also protect biodiversity, water quality, and other ecosystem services.

The King County Rural Forest Carbon Project is a Grouped Project including multiple properties. All acquired properties will be managed for conservation, including enhancing carbon storage, maintaining or improving fish and wildlife habitat, recreation, and with certain properties maintaining activities like selective thinning to enhance forest health and resilience.


tons of net CO2 emissions will be reduced over the project’s first 10 years (12.82 tons per hectare per year).

Impacts beyond carbon

Climate benefits and healthy communities

All of the properties included in the project are open for public use, expanding access to forested green space and providing physical and mental health benefits to the county’s residents. There is significant local support for additional parks, green space, and conservation in the rapidly developing area surrounding Seattle. Learn more about a few of their key initiatives:


Sustainable cities and communities

Acquiring properties for the King County Parks system, which provides employment opportunities, youth job training, education programming, and recreational access development.


Climate action

Protecting remaining high conservation value lands and securing a regional trail network within 30 years with The King County Land Conservation Initiative.


Clean water and sanitation

Protecting and restoring habitats in order to preserve and enhance the well-being of 2.25 million residents, fulfill tribal treaty rights, eliminate inequities, and recover threatened salmon and orca through the Clean Water Healthy Habitat Strategic Plan.

Sustaining habitat for salmon and other wildlife

Protecting these forests saves critical salmon habitat and preserves corridors for Washington State’s remaining elk, bears, and other wildlife in an increasingly fragmented and paved-over landscape. By maintaining forests on the landscape, the project also improves water quality and quantity throughout the county in parallel with improved air quality.

Western Red-Cedar

Native to the West Coast of the U.S., the western red cedar grows up to 300 feet tall, especially in moist, cool, or fertile areas, and can often live to 1,000 years old if undisturbed. It is one of the most culturally important species for Tribes in the Pacific Northwest, with high conservation value.

how this project helps

This project protects intact forests, including areas where western red-cedar is well-established. In cases where acquired forests have a low diversity of tree species, western red-cedar is one of the species planted.

Salmon image
tree spotlight

Salmon populations in the Puget Sound region have sustained Indigenous communities and played a key role in natural ecosystems for millennia. Puget Sound is home to five species of salmon including Pink, Chum, Chinook, and Coho, but habitat degradation and loss, along with overfishing, have led to sharp declines since the late 1800s. Degradation of riparian forests and loss of forest cover have altered in-stream conditions and have contributed to these declines.

how this project helps

Healthy riparian and upland forests protect salmon habitat. This project protects high-priority forestland, contributing to shading in riparian areas and keeping stream temperatures lower, while also protecting upland forests that provide water quality and quantity benefits essential for salmon.
