The agreement came at the end of a week-long meeting of the International Maritime Organisation, a United Nations body, in London, where small countries were pitted against large shipping nations that were against such restrictions.
Friday's agreement calls for global shipping emissions to peak as soon as possible, and to reduce the total annual greenhouse gas emissions by at least 50 percent of 2008 levels by 2050. It also calls for efforts to be pursued to phase out greenhouse gas emissions from shipping entirely.
