Insurers competing aggressively


Approaching the end of 2026, environmental insurance buyers enjoy an advantageous marketplace. New entrants are joining the market, with nearly 50 insurers now writing environmental insurance across several industries.

Both established and new carriers are eager to expand their market share. To do so, they are often competing aggressively on pricing for pollution legal liability (PLL), contractors pollution liability (CPL), combined general liability/pollution legal liability, and contractors professional and pollution (CPPI) policies. In the second quarter of 2026, median rates for PLL rose 2.0% year over year, according to Lockton data.

Prospective insurance buyers and the attorneys and consultants are more knowledgeable about the purpose and value of environmental insurance today, leading more organizations to proactively evaluate and purchase coverage.

Due to the expanded capacity in the marketplace premiums for up to ten year terms of historical liability are attractive in acquisitions and transactions. Environmental insurance is also being sought to address contractual liability concerns. For example, the environmental obligations in construction contracts are growing, leading contractors to turn to insurance solutions to protect against potentially costly exposures.


Broad coverage for complex environmental risks


Emerging environmental risks continue to present significant challenges for both businesses and insurers. Among the most prominent examples are per- and polyfluoroalkyl substances (PFAS, also known as “forever chemicals”) and ethylene oxide, both of which have become significant sources of long-tail environmental liability and litigation risk.

Historically, insurers have approached these risks cautiously. In the case of PFAS, many carriers previously imposed broad exclusions due to the lack of clear national exposure standards and uncertainty surrounding potential loss costs. Similar concerns have also influenced underwriting approaches to ethylene oxide, for which scientific, regulatory, and litigation developments have made potential liabilities difficult to quantify.

More recently, however, the market’s approach has evolved. As insurers have gained a better understanding of these exposures and accumulated greater underwriting experience, many have moved away from blanket exclusions toward more nuanced, risk-based underwriting. At the same time, abundant capacity and aggressive competition among carriers mean insurers are increasingly offering favorable pricing and breadth of coverage.

As a result, buyers have significant opportunities. Carriers are often willing to consider coverage enhancements and policy modifications that may have been more difficult to obtain in a tighter market. Rather than applying uniform exclusions, insurers are increasingly evaluating specific operations, controls, and exposure profiles when determining the scope of coverage they are willing to provide.

This shift is particularly evident with PFAS. Many carriers now differentiate between cleanup liabilities and bodily injury or property damage claims and may provide coverage where exposures are well understood and policies are appropriately structured. The availability of coverage reflects the market's growing ability to underwrite emerging environmental risks when supported by strong risk management practices and underwriting information.

Ethylene oxide presents a similar challenge. Commonly used in industrial processes, the gas has been linked to cancer and continues to generate substantial litigation activity. Facilities where ethylene oxide has been used or has been present historically may face bodily injury claims from employees, neighboring businesses, and surrounding communities, even when operating in compliance with applicable federal and state environmental regulations.

More broadly, plaintiffs’ attorneys are increasingly pursuing claims related to PFAS, ethylene oxide, and other environmental contaminants through aggressive pre-litigation strategies. Demand letters alleging environmental violations, bodily injury, emotional distress, and other damages are often used to exert significant pressure before formal litigation begins. While the amounts sought in these demands may ultimately exceed eventual settlement values, they nevertheless represent a growing source of liability exposure and defense costs for insureds.

Despite improving market conditions, underwriting remains highly risk-specific. While carriers are eager to deploy capacity, the ultimate scope of coverage depends on the nature of an insured’s operations, historical activities, and environmental exposures. For buyers, this underscores the importance of preparing well in advance of renewals and presenting a thorough, well-documented risk profile to insurers.

Bridging the gap between environmental & casualty coverage


An increasingly popular approach among insurance buyers is the use of bundled policies that combine environmental and casualty coverages under a single insurer, rather than requiring separate towers or carriers. As demand for integrated risk solutions continues to grow, insurers have expanded their offerings and capacity in this segment.

Bundled products offer several advantages for buyers, including potential cost savings. While buyers may spend somewhat more, overall costs are often less than they would be for separate coverage structures. Bundled solutions can be particularly attractive for manufacturers and companies with potential product-related pollution exposures, where the line between environmental liability and traditional casualty claims can become blurred, especially when it comes to the defense of a claim.

Importantly, bundled offerings allow for greater clarity of coverage. Consider a specialty chemical manufacturer that supplies an antimicrobial preservative to a personal care products manufacturer. The preservative is incorporated into finished products and sold to consumers. Years later, it is alleged that exposure to the chemical causes adverse health effects, resulting in bodily injury lawsuits against both the finished product manufacturer and the ingredient supplier.

Plaintiffs may allege that the chemical itself is harmful, that consumers were exposed through normal use of the product, and that the substance constitutes a contaminant or pollutant. Under a traditional general liability policy, insurers may raise questions regarding the applicability of the pollution exclusion, while environmental policies may have separate triggers, exclusions, or coverage requirements.

When product liability, general liability, and affirmative pollution liability coverage are combined under a single policy, the insured benefits from a coordinated claims response and greater certainty that bodily injury claims arising from the chemical exposure will not become the subject of coverage disputes between carriers.


Making the most of today’s market


Use today's favorable market to:

  • Reassess exposures.
  • Strengthen coverage.
  • Take advantage of abundant capacity.

Intense competition among insurers creates opportunities to negotiate broader terms, enhanced policy language, and more comprehensive protection while maintaining attractive pricing. Rather than focusing solely on premium reductions, buyers can use current market conditions to address coverage gaps and secure solutions tailored to evolving risks.

Companies should also consider integrated risk-transfer solutions. Combined environmental and casualty products can reduce coverage uncertainty, streamline claims handling, and minimize disputes over whether a loss falls under an environmental or casualty policy. As organizations evaluate environmental exposures and explore insurance solutions, working with a broker that specializes in environmental risk can be critical. Environmental policies are highly customizable, and the right advisor can help buyers look beyond premium costs to assess coverage quality, negotiate stronger terms, and tailor protection to their specific risk profiles.

Specialized expertise can also help organizations make informed decisions about coverage structure, limits, and policy design while ensuring environmental coverage aligns with the broader insurance program. Just as importantly, experienced brokers can help navigate complex claims and advocate for favorable outcomes when losses occur.
