Sudden and accidental pollution coverage is vanishing from standard insurance markets – and the shift is hitting energy operators hard.
“There is a growing trend where, particularly in the standard markets, there's movement away from offering sudden and accidental pollution coverage,” said Loren Henry (pictured), vice president of environmental and energy at Jencap. “There's been a logjam of claims and losses... and the cost of cleaning up pollution events is ever increasing – exponentially.”
As losses mount, many carriers are offloading pollution risk into the excess and surplus (E&S) market, where policies are less regulated and more responsive to real-time cost pressures. Unlike standard insurers, E&S carriers are not required to file rate changes with state regulators, giving them greater flexibility.
“They’re better equipped to handle that rapid development of costs,” Henry said. “Standard markets see that and they're trying to push sudden and accidental pollution coverage into the E&S market.”
That shift is proving expensive for insureds. Henry cited a recent case involving a refinery that had carried pollution coverage with a standard market insurer for over 25 years. When the insurer exited, the operation was forced into the E&S market – and its premium skyrocketed from $35,000 to $250,000 for the same $10 million limit.
“It was just such a huge increase,” he said. “The standard market had a GL policy – a standard 1-2 GL policy – and then they had a $10 million limit above that. So we had to go out to the E&S market and get $10 million in pollution limits, and it just ballooned.”
Still, Henry said many clients remain insurable – just not at the prices they’re used to. “I would use the term ‘uninsured’ more than ‘uninsurable,’” he said. “There is a space in the market for sudden and accidental pollution – for lease operators, for oil and gas production companies. It’s just a big shock coming into the E&S market from the standard market.”
Beyond pricing, new E&S policies are coming with stricter terms. Deductibles are higher – typically between $100,000 and $250,000 – and many exclude pre-existing conditions. For long-time policyholders, that means a loss of historical protections embedded in standard coverage.
“Already, just by switching from the standard market policy to the E&S policy, you've lost that tailwind of coverage that you had going back to when you started that original standard market policy,” Henry said.
Henry warned that capacity is also tightening. With fewer carriers willing to absorb long-tail environmental exposures, limits are being reduced and coverage increasingly structured in layers.
“Companies that maybe were putting up $10 million, $20 million, $25 million in limit are going to start tapering that down,” he said. “You might have someone that only puts up $5 million in the first layer, and then you've got to get another $5 million above that, and you build in chunks.”
That tower-building approach, common in auto liability, is now creeping into environmental risk – requiring more carriers to take on smaller portions of the total coverage.
“We’ll need more capacity. We’ll need more players in this space because there's not a ton of them right now,” Henry said.
For brokers and risk managers, the emerging challenge is twofold: managing rising costs while ensuring compliance. Environmental insurance is often mandated by regulators or contractual obligations, making coverage a legal necessity.
“This is the change that's coming down the pipeline,” Henry said. “Let's get ahead of it as soon as we can... If you want to stay within compliance, whether it's state, federal regulators or oil field contracts, this is the reality.”
Helping clients prepare early – rather than scrambling at renewal – will be critical. As Henry put it, the retreat from standard market pollution coverage isn’t the end of insurability, but it does mark a turning point in how environmental risks are priced, structured, and sustained.
