"KIGALI -- The world will not forgive leaders gathered in Rwanda this week if they fail to back a proposed agreement to cut greenhouse gases, a top U.N. official said on Thursday, calling the deal an easy one to achieve.
Representatives from about 150 nations heard the appeal as they opened negotiations on a deal to phase down the use of factory-made hydrofluorocarbon (HFC) gases, which are used in refrigerators, air conditioners and aerosols.
U.S. Secretary of State John Kerry was expected to join the conference later in the day. U.S. officials said they were optimistic an agreement could be reached at the meeting ending on Friday.
"No one, frankly, will forgive you if you cannot find a compromise at this conference," said Erik Solheim, executive director of United Nations Environmental Program (UNEP)."
