The Climate Action Against Disinformation (CAAD) coalition reported early in 2023 that a sample of fossil fuel sector-linked entities spent approximately 4 million USD on Meta for paid advertisements to spread false, misleading claims on climate crisis, net-zero targets and necessity of fossil fuels prior to and during COP27. The analysis identified 3,781 ads, the majority from Energy Citizens (an Anerican Petroleum Institute group). America’s Plastic Makers spent over $1 million and the Saudi Green Initiative ran 13 ads. There was a surprising increase in content related to outright climate denial, including a spike on Twitter for the hashtag #ClimateScam since July 2022.
