Activists have been expressing concerns about climate disinformation on Twitter after Musk's takeover. Although there has not been an explicit policy change in Twitter's approach to tackling climate disinformation on the platform, Musk fired Twitter's sustainability team within a wider cull of staff two days before the start of COP27. Jennie King, the head of civic action and education at the Institute for Strategic Dialogue (ISD), explained that Twitter was supposed to be the voice of COP27, according to a campaign planned in advance alongside climate advocates. However, she expressed that all the intermediaries in the company were laid off and that, since then, there has been a spike in outright climate denial on the platform.
