Weyerhaeuser

Weyerhaeuser engages in the upstream exploration and production of oil and natural gas through the leasing of its mineral rights. The company holds and markets leases for fossil fuel extraction on its land holdings. For example, state production records document active gas leases in Hidalgo County, Texas, operated by third parties like American Exploration Company under the "Weyerhaeuser" lease name. Historical drilling data also shows oil and gas production from a Weyerhaeuser well in Texas between 1985 and 1999.

This activity represents a direct, non-incidental revenue stream from fossil fuel extraction. While the scale of this operation relative to Weyerhaeuser's primary timber and forest products business is not detailed in the available evidence, the company's ongoing management and leasing of its mineral assets for oil and gas production places it within the upstream fossil fuel sector.

Weyerhaeuser has accumulated significant environmental penalties and liabilities related to its industrial operations. In 1998, the company’s pulp and paper mill in Longview, Washington, settled an EPA complaint for over $700,000. More recently, in January 2025, the Washington Department of Ecology issued a $145,000 penalty to Weyerhaeuser’s Longview lumber mill for 36 stormwater discharge violations, including 15 instances of noncompliance with permit limits. In October 2023, an environmental group filed a lawsuit alleging the company’s lumber mill regularly discharged wastewater exceeding permitted volumes and containing pollutants like oil and grease into the Columbia River, violating the Clean Water Act.

The company’s history includes multiple sites requiring environmental cleanup. Legal records from the 1990s indicate Weyerhaeuser was involved in efforts to address pollution damage at various locations, with situations requiring mandatory reporting of leaks, spills, or contamination to authorities. In 2025, the Washington Legislature allocated $20 million to clean up the former Weyerhaeuser Mill A site on Port Gardner Bay. ViolationTracker documents air pollution penalties against the company totaling in the tens of millions of dollars. This pattern of regulatory enforcement, alongside ongoing litigation and cleanup liabilities, demonstrates documented environmental harm from its operations.
