The civil case was filed in superior court in San Francisco against ExxonMobil, Shell, BP, ConocoPhillips and Chevron, which is headquartered in California. The American Petroleum Institute, an industry group, is also a defendant in the case.
“Oil and gas company executives have known for decades that reliance on fossil fuels would cause these catastrophic results, but they suppressed that information from the public and policymakers by actively pushing out disinformation on the topic,” the 135-page complaint read.
“Their deception caused a delayed societal response to global warming. And their misconduct has resulted in tremendous costs to people, property, and natural resources, which continue to unfold each day.”
The suit seeks the creation of an abatement fund to pay for future damages caused by climate disasters in California, which is on the front lines of climate change-fueled wildfires, flooding and other extreme weather phenomena.
“By downplaying the scientific consensus on climate change and emphasizing uncertainty, Defendants hoped to delay any regulatory action that might seek to reduce or control (greenhouse gas) emissions, thereby threatening the industry’s profits,” the complaint added.
Representatives of the defendants did not immediately reply to requests for comment from AFP.
“For more than 50 years, Big Oil has been lying to us – covering up the fact that they’ve long known how dangerous the fossil fuels they produce are for our planet,” California Governor Gavin Newsom said in a statement on Friday.
“California is taking action to hold big polluters accountable,” he added.
Since the current wave of environmental litigation against fossil fuel firms began around 2017, the industry has sought to avoid state trials on procedural grounds.
That effort received a major blow in May when the US Supreme Court declined to consider an appeal in two cases, meaning they could proceed.
The lawsuits are modeled on successful cases against Big Tobacco as well as against the pharmaceutical industry over the proliferation of opioids.
