The city of Chicago is suing six oil and gas giants, as well as an industry trade group, which “funded, conceived, planned, and carried out a sustained and widespread campaign of denial and disinformation about the existence of climate change and their products’ contribution to it.” Progressive Chicago Mayor Brandon Johnson filed the lawsuit Tuesday against ExxonMobil, Chevron, BP, Shell, ConocoPhillips, Phillips 66 and the American Petroleum Institute. The suit lays out the climate crisis impacts faced by Chicago, including more frequent and intense storms, flooding, droughts, extreme heat waves and shoreline erosion. Chicago joins eight other states, the District of Columbia and multiple municipalities across the U.S. that have filed similar lawsuits against Big Oil over their role in exacerbating the climate crisis.
