SEATTLE — Weyerhaeuser and The Nature Conservancy (TNC) announced a multiyear collaboration to further the scientific understanding of how forests and forest products contribute to climate mitigation. …TNC pioneered research quantifying nature’s full ability to absorb and store carbon and provide a scalable and readily available opportunity to mitigate climate change. These natural climate solutions can help protect, better manage and restore forests to reduce or absorb 11 billion metric tons of GHGs per year. Over 1 billion metric tons of that potential could come from improved management of working forests. …Over the next several years, Weyerhaeuser and TNC will collaborate on forest research; implement standards and frameworks for greenhouse gas accounting; support the development of improved carbon project methodologies; and help shape strategies that accelerate the adoption of climate-smart forestry practices worldwide.
