PR giant Edelman worked with Koch network, despite climate pledges

Move by world’s largest public relations company, uncovered by tax records, alarms climate advocates

Edelman, the world’s largest public relations company, was among the Charles Koch Foundation’s highest-paid vendors in 2022, a 990 tax disclosure form shows, alarming climate advocates.

The PR giant has made numerous climate declarations over the past decade, including making a pledge to eschew projects promoting climate denial. Partnering with a part of the Koch network, which has long worked to sow climate doubt, calls those pledges into question, said Duncan Meisel, the executive director of Clean Creatives, a non-profit pushing creative agencies to cut ties with fossil fuel polluters.
