"Some of the world’s top PR companies have for the first time publicly ruled out working with climate change deniers, marking a fundamental shift in the multi-billion dollar industry that has grown up around the issue of global warming.

Public relations firms have played a critical role over the years in framing the debate on climate change and its solutions – as well as the extensive disinformation campaigns launched to block those initiatives.

Now a number of the top 25 global PR firms have told the Guardian they will not represent clients who deny man-made climate change, or take campaigns seeking to block regulations limiting carbon pollution. Companies include WPP, Waggener Edstrom (WE) Worldwide, Weber Shandwick, Text100, and Finn Partners."
