Edelman is following its own PR strategy. Earlier this month, it concluded a two-month study of its climate principles and scrutinized more than 330 of its 2,000 clients, including “a deep dive” on 20 whose emissions are particularly large. That group includes ExxonMobil, Royal Dutch Shell, and American Fuel and Petrochemical Manufacturers (AFPM), according to Clean Creatives. So far, however, Edelman has not severed ties with any clients.
