During the annual meeting of the Scientific Steering group of the Global Carbon Project in April 2013, the U.S. Carbon Cycle Science Program Office presented the Program’s short and long-term USGCRP aligned priorities and discussed potential future activities with the GCP. The GCP Scientific Steering Group (SSG) discussed the newly developed Global Carbon Atlas and the newly formulated goals of 'Future Earth' which will incorporate the GCP. The GCP-IIASA workshop on 'negative emissions'immediately preceded the SSG meeting, which will yield a series of international papers on this emission reduction option's science, technology and policy aspects.
