New Tactic in Climate Change Litigation Could Cost Energy Companies Billions. Or Not.

There s a lovely neighborhood in Marin County, California where we recently thought about buying a house. The lots in Bel Marin Keys aren t big, but they back to lagoons connected to the San Pablo Bay. Just about everyone has a dock in their backyard.

And then we remembered. In a few decades, the whole place will probably be flooded, covered by a foot or so of water, thanks to global warming.

This week, Marin and two other coastal communities in California hit back, suing 37 giant oil, gas and coal companies in a first-of-its-kind bid to win compensation for costs related to rising sea levels.

Defendants include ExxonMobil, Chevron, BP, Shell, ConocoPhillips and Arch Coal companies that the plaintiffs assert are together responsible for about 20 percent of global greenhouse gas emissions.

This type of state common law climate litigation has been a long time coming, and these cases may well represent the first of a slew of similar cases nationwide, Michael Burger, executive director of the Sabin Center for Climate Change Law, wrote in Columbia Law School s climate law blog. Importantly, these cases have been filed at a particular moment in time, when scientific consensus on and understanding of climate change is at an all-time high but the federal government s commitment to addressing the problem is at an all-time low.

The trio of nearly identical state court suits by Marin and San Mateo counties and the city of Imperial Beach are the latest attempts to address climate change through the courts. In Oregon, 21 young Americans are edging toward trial in a suit against the federal government alleging that their constitutional rights were violated by policies promoting the production of fossil fuels. And the attorneys general of Massachusetts and New York have launched a fraud investigation against ExxonMobil, looking at whether the company misled shareholders and the public about climate change.

The California suits are trying another approach.

The governments are represented by environmental plaintiffs firm Sher Edling, which according to Marin County deputy counsel Brian Case is handling the case on contingency. Taxpayers are not being asked to bear the risks of this lawsuit, he said.

It does seem like a bit of a long shot.

Optimistically, name partner Vic Sher in an interview likens the suits to Big Tobacco and MTBE litigation.

There are certainly some similarities. Like the tobacco companies, the oil and gas defendants allegedly knew about the hazards associated with their products, acted to conceal the knowledge and have profited handsomely for years.
