Lead the world toward an effective and equitable global climate agreement Support efforts to stop emissions from deforestation and degradation in developing countries. Contribute to global financing mechanisms for climate mitigation and adaptation in the developing world. Ensure that climate change-related impacts are addressed under the Endangered Species Act.
