Our organizations have worked to protect federal forests, wildlife, watersheds, and our climate for decades. We’ve come together to launch the Climate Forests Campaign because conserving our remaining older forests and trees on federal public lands is one of the country’s most straightforward, impactful and cost-effective climate solutions. This must be prioritized alongside rapidly reducing greenhouse gas emissions. We are calling on the Biden Administration to enact a strong, lasting rule that protects mature trees and forest stands from logging across federal lands as a cornerstone of US climate policy. The older parts of our nation’s forests are climate and biodiversity champions — they sequester large amounts of carbon and can store that carbon for centuries, providing the foundation for a diversity of life. If the Administration is going to lead in solving the climate and biodiversity crises, it must protect these carbon critical climate forests and set an example for the world.
