• Washington residents sue Big Oil for climate-driven insurance rate hikes.
• Lawsuit cites decades of internal fossil fuel research on extreme weather and rising risks.
• U.S. climate disasters cause billions in insured losses, pushing premiums higher.

Two Washington residents claim that oil giants such as Exxon Mobil, Shell, Chevron, and ConocoPhillips, along with the American Petroleum Institute, are responsible for worsening climate-related risks.

According to the filing, the consequences of climate change have pushed insurers to raise premiums, thereby leaving households with higher costs.

The lawsuit argues that these oil companies had decades of internal research showing that fossil fuel emissions would intensify extreme weather, sea-level rise, and large-scale economic damage.

Despite this, the companies protected their own assets from climate impacts and continued expanding fossil fuel production.

The plaintiffs describe this behaviour as misleading because the companies were said to have understood that increased climate risks would place pressure on insurance markets.

Their filing brings attention to rising climate-driven natural catastrophes, which have created steep financial losses for the insurance industry.

Climate-related disasters, notes a report, have increased significantly since 2018, with billions in insured losses recorded every year.

In 2023, natural catastrophes caused about $114 billion in economic losses, with nearly $80 billion covered through insurance. Through the first three quarters of 2024, losses logged $145 billion, again with $80 billion insured.

These figures explain why insurers have raised premiums in multiple states, including Washington, where wildfire risk, storm damage, and record heat have intensified.

The plaintiffs give their personal examples to show the scale of the financial impact. One resident saw his annual premium rise from $1,012 in 2017 to $2,149 in 2022, an increase of 113%.

The other plaintiff experienced a similar rise and had to switch to a cheaper policy with reduced protection despite living in an area described as dry and prone to forest fires.

They state that they were unaware of what they describe as misleading conduct by the defendants regarding climate risks tied to fossil fuel use.

However, oil businesses deny the accusations and describe the lawsuit as part of a coordinated attack on an industry that powers daily life. Previous federal cases relating to climate liability have largely been dismissed for jurisdictional reasons, leaving the question unresolved.
