Earlier this month, many saw the COP22 meeting in Marrakesh, Morocco, as an opportunity for decisionmakers from around the world to begin discussion on implementation of the climate commitments made the previous year in Paris. With President-elect Trump pledging to withdraw the United States from the Paris Agreement, concerns have moved from implementation to how the Agreement might progress without U.S. involvement. At the conference last week, attendees were hopeful that China will take the lead in reducing global carbon emissions. It is unclear how the international community would respond to U.S. withdrawal, though the idea of economic sanctions, a carbon tax levied on the U.S., reduced military cooperation, and faltering trade agreements have been rumored. Should the United States withdraw from the Paris Agreement, it would be one of two nations to do so, the other being Nicaragua on the grounds that it was too weak.
