What Green Diamond does

Green Diamond Resource Company is a sixth-generation, family-owned forest products company founded in 1890 (originally as Simpson Logging Company) and headquartered in Seattle. It owns and manages approximately 2.2 million acres of timberland across nine states in the western and southern United States, including wholly owned operations in Washington, Oregon, California (anchored by the Korbel Tree Nursery), Montana, and the Southeast, plus the Green Diamond Management Company subsidiary that operates the Twin Creeks timber portfolio. The company is among the five largest U.S. timberland owner-operators, with 100% of its forests certified to the FSC and SFI sustainable management standards.

The business operates five revenue lines: (i) timber sold directly to local sawmills for lumber and related products; (ii) wood chips exported via the company's Humboldt Bay facility (one of only three West Coast facilities capable of loading ocean-going vessels) to pulp mills in Japan, China, and the U.S., plus compressed wood pellets for European energy markets; (iii) forest carbon credits from 14 Improved Forest Management and Afforestation/Reforestation projects spanning 700,000+ acres across five states, with over 7 million mtCO2e issued by year-end 2025; (iv) third-party forest management and co-investment services through Green Diamond Management Company, which manages 628,000 acres including the Twin Creeks joint venture with Silver Creek Capital Management; and (v) woody biomass products sold to biorefineries and renewable energy buyers. Underlying technology includes LiDAR forest canopy mapping, heavy-lift drones (~45 lb payload) for equipment transport, and the Korbel Nursery's proprietary genetic tree improvement and redwood propagation program, supplemented by remote water temperature monitoring across nearly 100 fish-bearing streams.

Revenue mechanics are predominantly B2B and direct: timber and chips transact at negotiated unit prices pay-as-you-go, while carbon credits are sold through a dedicated sales team via spot transactions, annual renewals, or multi-year offtake agreements (Microsoft is a named buyer); forest management services earn multi-year contractual fees from institutional investors. Pricing is not publicly disclosed across any line. Green Diamond harvests less than 2% of its land per year under continuous-cover silviculture, holds 60+ species Habitat Conservation Plans covering 1.5M+ acres, and serves as operating partner to Silver Creek Capital Management through the 2015 Twin Creeks joint venture.

Revenue model

1. Timber Sales: Green Diamond's primary source of revenue comes from sustainably harvested timber. The company manages a continuous cycle of harvesting and replanting across its 2.2 million acres. Timber products include logs for lumber and other forest products supplied to local sawmill customers, creating household essentials, community infrastructure, and long-lasting homes. Products include lumber for homes and furniture, and other products such as floral greens.
2. Wood Chip Exports: Wood chips are generated as a byproduct from sawmill processing of harvested trees. Green Diamond operates a chip facility on Humboldt Bay, one of only three West Coast facilities that can load ocean-going wood chip vessels. Chips are sold to pulp mills in Japan, China, and the U.S. domestic market. Whole-log chipping also processes smaller logs and other tree parts (tanoak, red alder, Sitka spruce) for domestic pulp facilities. Southeast timberlands produce SFI-certified wood chips for European markets as compressed wood pellets.
3. Carbon Credits: Green Diamond develops, owns, and manages U.S.-based forest carbon projects across Compliance and Voluntary markets. The portfolio includes 14 Improved Forest Management (IFM) and Afforestation, Reforestation and Revegetation (ARR) projects spanning 700,000+ acres across five states. The company has issued over 7 million mtCO2e sequestered and issued as carbon credits as of end of year 2025. Credits are sold via spot transactions, annual contract renewals, and multi-year offtake agreements.
4. Biomass and Renewable Energy: Green Diamond supplies woody biomass products including pine needles, sawdust, and slash from thinning projects to biorefineries. Southeast operations supply European customers with wood chips and pellets for power plants and home heating. The company is also involved in research projects such as Waste to Wisdom to identify ways to make biomass fuel production more cost-effective.
5. Forest Management Services: Through Green Diamond Management Company, the company provides active forest management, responsible harvesting, and log marketing services as a co-investor in various forestry operations. Services include management to enhance forest health and productivity, marketing and sales, evaluation and acquisition of forest lands, and recreation access and carbon ecosystem services assessment. Revenue comes from fees for managing co-investment portfolios.

Core offering

Green Diamond is a forest products company that owns and manages 2.2 million acres of working forests across nine U.S. states, harvesting and selling sustainable timber logs to sawmills, producing and exporting wood chips to pulp mills globally, developing and selling verified forest carbon credits across compliance and voluntary markets, supplying woody biomass for renewable energy customers, and providing third-party forest management services to institutional timber investors.

Product overview

Green Diamond operates as a single unified offering of forest products and land management services across five business lines, rather than a platform-plus-modules architecture. The core portfolio consists of Timber (sustainably harvested logs for sawmills), Wood Chips (residual wood for paper and pulp mills via their Humboldt Bay facility), Co-Investment and Forest Management (outsourced timberland management for institutional investors via Green Diamond Management Company), Forest Carbon Credits (Improved Forest Management and Afforestation/Reforestation projects generating verified carbon offsets), and Biofuel/Renewable Energy (biomass products for power plants and biorefineries). These products share the common thread of sustainable forest stewardship and operate from Green Diamond's 2.2 million acres of owned and managed timberlands across nine western and southern U.S. states.

Scale indicators19 records

Recent moves11 records

Expansion highlights6 records

Emerging players

• Pachama: Technology-driven forest carbon marketplace and project developer. While not a timberland owner, Pachama operates in the same forest carbon credit supply chain that Green Diamond monetizes through its 14-project portfolio, serving overlapping corporate buyers like Microsoft.
• NCX (Natural Capital Exchange): Forest carbon marketplace and project facilitator working with U.S. family forest owners. Competes with Green Diamond for the same pool of corporate carbon-credit buyers and represents both an alternative channel and a potential partner for forest carbon origination.

Regional players

• Hampton Lumber: Privately held, family-owned forest products company with sawmills and timberlands concentrated in the Pacific Northwest and Northern California. Comparable to Green Diamond's PNW operations in species mix (Douglas-fir, redwood), customer base, and sawlog marketing model.
• Stimson Lumber: Privately held forest products company with ~145,000 acres of Oregon timberland and sawmill operations. Comparable to Green Diamond's Oregon and Washington divisions on private timberland management and sawlog sales in the Pacific Northwest.

Direct peers

• PotlatchDeltic: Public timber REIT (~1.9M acres) with timberlands, wood products, and real estate segments across the U.S. South and Pacific Northwest. Directly comparable to Green Diamond on Southern and Western timberland ownership, certification, and downstream log marketing.
• CatchMark Timber (Triple T Holdings): Timberland investment and management company (~275,000 acres across U.S. South and Pacific Northwest). Highly comparable to Green Diamond's Twin Creeks co-investment model as a third-party timberland asset manager for institutional capital.
• Rayonier: Public timber REIT owning ~2.7M acres of timberland with timber, real estate, and forest resources segments. The company's former CEO (David Nunes) currently serves on Green Diamond's board, underscoring direct operational overlap in U.S. timberland management.
• Sierra Pacific Industries: Privately held, family-owned forest products company owning ~2.4M acres of California timberland with integrated sawmill, plywood, and biomass operations. Closest private-peer analog to Green Diamond given overlapping California footprint and vertically integrated model.
• Weyerhaeuser: Largest private timberland owner in the world (~12.4M acres) and a publicly traded timber REIT. Operates the same integrated timber-to-products model with sawlog sales, land sales, and wood products manufacturing — the most directly comparable U.S. timberland operator to Green Diamond at scale.

Broad incumbents

• Plum Creek Timber Company (merged into Weyerhaeuser): Formerly the largest private timberland owner in the U.S., now part of Weyerhaeuser. Plum Creek's former president (Thomas Lindquist) sits on Green Diamond's board, indicating direct strategic comparability in Western and Southern timberland operations prior to the merger.
