Environmental Insurance
Standard general liability and property policies exclude pollution risk almost universally, leaving most organizations covered for everything except the one exposure they are least prepared to fund themselves. HUB's environmental insurance advisors identify that gap and place coverage through dedicated surplus and specialty market relationships.

Where standard insurance buying leaves pollution risk uncovered
Environmental exposure creates three distinct pressures: coverage that standard markets were never built to provide, an exclusion most buyers do not know they carry and claims that pull in regulators and remediation parties a standard adjuster rarely handles. Each pressure calls for a different response.
Pollution coverage sits outside standard general liability and property forms entirely, placed instead in a surplus and specialty market where capacity, appetite and policy language vary by carrier. For higher-hazard risks and properties with known conditions, that market narrows further.
Environmental coverage is placed predominantly in the surplus and excess & surplus market, where carriers disagree on what counts as a covered pollutant and capacity for higher-hazard risks is limited. Organizations with known, pre-existing pollution conditions face outright exclusion from many carriers, with no standard-market fallback available.
An independent broker with dedicated environmental market relationships can place coverage, including for known pre-existing conditions, that a generalist broker without surplus lines access cannot reach. The starting question is not which carrier offers the best terms but which carriers will underwrite the risk at all.
Organizations rarely ask whether their broker has real environmental market access until a generalist broker comes back with no options. By then, the search for a specialist should have already started.
The organizations who secure coverage for an exposure the standard market was never going to underwrite in the first place is the one who leverages their broker’s specialized carrier relationships that a generalist broker simply does not have.
An absolute pollution exclusion appears in roughly 98% of general liability and property policies, so most organizations that believe they are covered for environmental exposure simply are not. The gap stays invisible until a claim is denied under that exclusion.
Organizations outside obviously environmental industries, real estate, hospitality, healthcare, agribusiness, often assume they carry no pollution exposure and never raise it with their broker. This is not a limits question, as in Property or Casualty; it is a total absence of coverage most buyers miss.
Proactive exposure identification, rather than waiting for a client to raise pollution coverage, paired with policy language negotiated to the organization's specific pollutant definition, facility profile and, for contractors, project phase, closes the gap before it becomes a denied claim.
The question that surfaces this exposure is rarely “do we need pollution coverage”; it is “what exactly does our current policy exclude,” asked before a claim, not after.
A successful organization is the one who discovers and closes a coverage gap before a claim occurs, rather than discovering it the hard way when a claim is denied under a policy it assumed would respond.
Environmental claims frequently draw in regulators and multi-party remediation, combining first-party cleanup costs with third-party bodily injury and property damage liability. A standard-lines adjuster is rarely equipped to navigate that combination, and the claim can stall while parties work out who leads.
Pollution claims unfold differently than a standard property or casualty claim, often involving environmental regulators, remediation contractors and multiple affected parties at once. Cleanup, defense and third-party liability costs all move simultaneously, and organizations need a broker who has handled a pollution claim, not just placed the policy.
Claims advocacy from a broker with genuine environmental claims experience, coordinating between the client, the carrier and any regulatory or remediation parties involved from the moment an incident is reported, keeps cleanup, defense and liability moving together instead of stalling.
The claim is resolved with cleanup, defense and liability costs addressed in a coordinated way, rather than managed piecemeal by parties unfamiliar with environmental claims.
Our Areas of Expertise
A practice built around finding the gap and filling it
Standard brokers add an endorsement and move on. HUB starts by identifying exposure the client did not know it had, then places coverage through dedicated surplus and specialty market relationships built specifically for pollution risk and stays involved when a claim happens.

Most organizations do not raise pollution coverage with their broker because they do not know they need to. HUB's environmental advisors proactively identify exposure across industries that rarely think of themselves as environmentally exposed, including real estate, hospitality, healthcare, agribusiness and transportation, then negotiate policy language, pollutant definitions and facility-specific terms rather than relying on standardized forms that do not exist in this market. For contractors, coverage is designed around project phase — site preparation, demolition, excavation — and project structure, including owner-controlled and contractor-controlled wrap-up programs, so the policy tracks the actual risk rather than a static annual snapshot.
Environmental coverage lives predominantly outside the standard market, in a surplus and excess & surplus market where carrier appetite, capacity and policy language vary considerably. HUB's placement relationships extend to markets willing to underwrite known, pre-existing pollution conditions that many carriers exclude outright, coverage a generalist broker without dedicated environmental-market access typically cannot reach. This market access is the capability that most distinguishes this advisory work from a standard commercial placement, where the question is which carrier offers the best terms rather than which carriers will underwrite the risk at all. Policy language, pollutant definitions and per-occurrence versus aggregate structures also vary enough by carrier that the placement conversation is as much about wording as about price.
