Climate Risks Series, Part 1: Climate litigation and severe weather fuelling insurance coverage disputes
The global rise in climate litigation looks set to continue, with oil and gas companies increasingly accused of causing environmental damage, failing to prevent losses occurring, and improperly managing or disclosing climate risks. Implementation of decarbonisation and climate strategies is subject to scrutiny across all industry sectors, with claims proceeding in many jurisdictions seeking compensation for environmental harm as well as strategic influence over future regulatory, corporate or investment decisions.
Evolving risks associated with rising temperatures have significant implications for the (re)insurance market as commercial policyholders seek to mitigate exposure to physical damage caused by severe weather events; financial loss arising from business interruption; liability claims for environmental pollution, harmful products or ‘greenwashing’; reputational risks; and challenges associated with the transition towards clean energy sources and net zero emissions.
Litigation Trends
Cases in which climate change or its impacts are disputed have been brought by a wide range of claimants, across a broad spectrum of legal actions including nuisance, product liability, negligence, fiduciary duty, human rights and statutory planning regimes. Approximately 75% of cases so far have been commenced in the US, alongside a large number in Australia, the EU and UK.
Science plays a central role and can be critical to determining whether litigants have standing to sue. The emerging field of climate physics allows for quantification of greenhouse gas (“GHG”) emitters’ responsibility, with around 90 private and state-owned entities found to be responsible for approximately two-thirds of global carbon dioxide and methane emissions. Recent advances in scientific attribution may provide evidence for legal causation in claims relating to loss from climate change or severe storms, flooding or drought.
Directors of high-profile companies may be personally targeted in such claims as liable for breach of fiduciary duties to the company or its members, in failing to take action to respond to climate change, or approving policies that contribute to harmful emissions.
Recent Cases
An explosion of ‘climate lawfare’ has kicked off in recent years, with the cases highlighted below indicative of key themes.
Smith v Fonterra [2024]
The New Zealand Supreme Court reinstated claims, struck out by lower courts, allowing the claimant Māori leader with an interest in customary land to proceed with tort claims against seven of the country’s largest GHG emitting corporations, including a novel cause of action involving a duty to cease materially contributing to damage to the climate system. This was an interlocutory application and the refusal to strike out does not mean that the pleaded claims will ultimately succeed on the merits. However, the judgment is significant in demonstrating appellate courts’ willingness to respond to the existential threat of climate change by allowing innovative claims to be advanced and tested through evidence at trials.
R v Surrey County Council [2024]
In a case brought by Sarah Finch fighting the construction of a new oil well in Surrey, the UK Supreme Court (by a 3:2 majority) ruled that authorities must consider downstream GHG emissions created by use of a company’s products, when evaluating planning approvals. The Council’s decision to grant permission to a developer was held to be unlawful because the environmental impact assessment for the project did not include consideration of these “Scope 3” emissions, when it was clear that oil from the wells would be burned.
Verein KlimaSeniorinnen [2024]
An association of over 2,000 older Swiss women complained that authorities had not acted appropriately to develop and implement legislation and measures to mitigate the effects of climate change. The Grand Chamber of the European Court of Human Rights held that Article 8 of the European Convention encompasses a right for individuals to effective protection by state authorities from serious adverse effects of climate change on their life, health and wellbeing. Grand Chamber rulings are final and cannot be appealed: Switzerland is now required to take suitable measures to comply. While not binding on national courts elsewhere, the decision will be influential.
ClientEarth v Shell [2023]
The English High Court dismissed ClientEarth’s attempt to launch a derivative action against the directors of Shell plc in respect of their alleged failure to properly address the risks of climate change, indicating that claims of this nature brought by minority shareholders will face significant challenges. The Court noted that directors (especially those of large multinationals) need to balance a myriad of competing considerations in seeking to promote the success of the company, and courts will be reluctant to interfere with that discretion, making it harder to establish that directors have breached their statutory duties.
US Big Oil lawsuits
Following lengthy disputes over forum, proceedings against oil and gas companies in the US are gaining momentum, paving the way for the claims to be substantively examined in state courts. Many actions against the fossil fuel industry seek to establish that defendants knew the dangers posed by their products and deliberately concealed and misrepresented the facts, akin to deceptive promotion and failure to warn arguments relied upon in other mass tort claims in the US, arising from the supply of tobacco, firearms or opioids.
Implications for Policyholders
With increasing volatility and accumulation risk, insurers will look to mitigate exposures through wordings, exclusions, sub-limits and endorsements. The duty to defend is the first issue for liability insurers, given the number of policyholders affected and the potential sums at stake in indemnity and defence costs.
In 2021, the Lloyd’s Market Association published a model Climate Change Exclusion clause (LMA5570). Property policies exclude gradual deterioration, with express wording or impliedly by the requirement of fortuity, and liability insurance typically excludes claims arising from pollution.
Lawsuits have been filed in the US over insurance coverage for climate harm, including Aloha Petroleum v NUF Insurance Co of Pittsburgh (2022), arising from claims by Honolulu and Maui, and Everest v Gulf Oil (2022), involving energy operations in Connecticut. Policy coverage may depend on whether an “occurrence” or accident has taken place, as opposed to intentional acts or their reasonably anticipated consequences (Steadfast v AES Corp (2011).
Policyholders should review their insurance programmes with the benefit of professional advice to ensure adequate cover for potential property damage, liability exposures and legal defence costs.
In the following instalments of our Climate Risks Series, we will examine the impact of reinsurance schemes and parametric solutions, and coverage for storm and flood-related perils in light of recent claims experience.

Archer v Ace (or, The Demise Of LEG3?)
Introduction
In the London Market there is, by and large, a common understanding about how LEG3 and the other defects exclusions operate, and what they are intended to do. That doesn’t mean that disagreements don’t arise about how a particular defects exclusion might apply to a particular set of facts, but those disagreements tend to be relatively rare, and the London Market tends to deal with what we call Construction All Risks claims (or what would be known in the US as Builders’ Risk claims), quite well on the whole.
As a result, those using the defects exclusions in the London Market, whether that is insurers, brokers, or the more sophisticated policyholders, tend to overlook the fact that several of the clauses, in both the LEG and DE suites of exclusions, are actually very difficult to understand for those who come to the clauses with the (surely reasonable) aspiration of wanting to determine the meaning of the clauses from the words that they contain.
Towards the end of last year I wrote about the potential impact of the first Court decision anywhere in the world which considered the meaning of the defects exclusion which (along with DE5, which is much less commonly used outside the UK) is intended to preserve the most generous coverage for damage to works under construction, LEG3, in the case of South Capitol Bridgebuilders v Lexington. That case was decided by a Court in the District of Columbia, but applied the Law of Illinois. Now, like buses, a second decision has been handed down in the US which considers LEG3, this time applying the Law of Florida, in the case Archer Western - De Moya Joint Venture v Ace American Insurance Co.
The decision in SCB sounded alarm bells for the Builder’s Risk community in the US, and presumably also for the LEG Committee, who are responsible for the LEG defects exclusion clauses. It raised at least two questions of significance: what constitutes damage for the purpose of triggering a Builder’s Risk policy; and what is the meaning of the LEG3 clause? Its answers to those questions were striking: property that from an English law perspective would have certainly been regarded as merely being in a defective condition was held by the Court in SCB to have suffered damage. With regard to the meaning of LEG3, the Court in SCB appeared to be unable to form a view, and held that the clause was ambiguous: “egregiously so”.
The big question for those who, like me, have an interest in the health of the Builder’s Risk market, was whether SCB would come to be regarded as an outlier decision, or one that would have a meaningful impact? Archer v Ace suggests the latter.
The judgment in Archer concerns an application for summary judgment by the insurer which was denied, and so the issues in the case will continue towards a substantive trial in due course. However, the judgment runs to some 66 pages, and so the issues were considered in some detail. I am not going to try to cover all of the detail but, as with my article on SCB, am going to focus instead of what the most important elements might mean for the Builder’s Risk market.
The facts
Again, I’ll start with a very brief description of the facts, which up to a point may create a sense of Deja Vu for those familiar with the SCB decision. Once more we have a Builder’s Risk claim relating to inadequate concrete in a bridge under construction. We have a disagreement about whether the works under construction were damaged (so as to trigger the Builder’s Risk policy), or whether the works were merely defective (which would not trigger the policy). We have a policy that contains a LEG3 defects exclusion. And we have disagreements about what LEG3 means, and about how one might establish what constitutes the “improvements” with which LEG3 is concerned.
In Archer the policyholder was a design and build contractor for the snappily titled “I-395/SR 836 Reconstruction / Rehabilitation Project” in Miami, Florida, which included the construction of a “signature bridge”. The design of the bridge involved batches of concrete, the production of which included the addition of “fly ash” from a pressurised fly ash silo, which had a mechanical system which was intended to allow specified amounts of fly ash to be added to the concrete batches. At some point between August and November 2020 the pressure relief valve of the silo failed, so that certain batches were “adulterated by an excessive amount of fly ash”.
I am not my firm’s expert on concrete (the “I ❤️ concrete” mug on my colleague Joanna Grant’s desk probably tells you who is) but, as the Court explained in Archer, although cement and concrete are terms that are often used interchangeably, they aren’t the same. Rather, cement is one of the ingredients of concrete, with the other common ingredients of concrete being fly ash, water, and aggregates. So, the presence of fly ash in concrete is not a problem in and of itself. In fact, in one sense, the more fly ash there is in the concrete, the better, as long as using additional amounts of fly ash does not come at the expense of the amount of cement used. High proportions of both fly ash and cement “generally increases the overall compressive strength of the concrete”. The problem comes when, as in Archer, additional amounts of fly ash are used at the expense of the amount of cement used. Then the compressive strength of the concrete is impaired.
When the policyholder became aware that some of the concrete had inadequate compressive strength, it submitted a claim for indemnity for the cost of repairing the concrete. The insurer denied coverage “reasoning the concrete constituted a defective material due to to the excess fly ash, and `because of this defect the material was never in a satisfactory state and therefore was not damaged’”.
Based on the above, the Court was required to address the following questions:
- Did the insured property suffer damage?
- Is LEG3 ambiguous?
In approaching those questions, the Court applied the test for summary judgment under the Law of Florida, which is that “summary judgment is appropriate where there is ‘no genuine issue as to any material fact’, and the moving party is ‘entitled to judgment as a matter of law’” (per Federal Rule of Civil Procedure 56), and that “when deciding whether summary judgment is appropriate, the court views all facts and resolves all doubts in favour of the non-moving party”.
It also applied the test for ambiguity under the Law of Florida, which is that “a policy is ambiguous only when ‘its terms make the contract susceptible to different reasonable interpretations, one resulting in coverage and one resulting in exclusion’”, and that “if there is an ambiguity, then it is construed against the insurer and in favour of coverage”.
As I did in my SCB article, I’ll explain what the Court held in relation to each issue, and add some comments of my own.
Did the insured property suffer damage?
As with SCB, the policy in Archer didn’t define the term “damage”. However, rather than just going to the dictionary, as the judge had done in SCB, the judge in Archer held that the test for damage had been determined by previous cases, and that it “requires a tangible alteration to the covered property”. That test is largely consistent with the test under English law, which requires a change in the physical condition of the insured property, which impairs the value or the usefulness of that property.
On the facts, and based on the high bar required to give summary requirement, the judge was “not prepared to accept the insurer’s argument that damage to the cement did not involve a physical alteration” and so that issue will remain to be determined at trial.
From an English law perspective, the issue is an interesting one, and the correct answer is not obvious. The correct answer will, in my view, turn on what is considered to be the relevant property: the concrete, or the cement?
If I was representing the policyholder, I would be arguing that the relevant property is the cement, and that the cement has become damaged by being overlaid with excessive quantities of fly ash. We know, from cases such as Hunter v Canary Wharf and R v Henderson, that the deposit onto insured property of excessive quantities of benign substances is capable of constituting damage, where the excessive quantities of those substances cost more money to remove than if ordinary quantities of those substances were present. On that basis, I would argue that the cement has undergone an adverse change in physical condition, that impairs both its value and its usefulness by coming into contact with excessive amounts of fly ash: the policyholder started out with cement which had a particular value, and as a result of the change in physical condition that occurred when the fly ash was added, it no longer retains that value.
If, on the other hand, I was representing the insurer, I would be arguing that the relevant property is the concrete, and that it was in a defective condition from the moment it was created (by the mixing of the cement and the fly ash). I would argue that from that point onwards it didn’t undergo any further “tangible alteration”, meaning that the test for damage hasn’t been satisfied. We know from the Bacardi case that, in English law, the creation of a defective finished product doesn’t constitute damage. Although Tioxide tells us that damage does occur when a defective finished product undergoes a change in physical condition that constitutes a further impairment of value or usefulness, that hasn’t happened in Archer, where the concrete was under-strength as soon as it came into existence, and remained that way until discovery.
So, which material should the Court be concerning itself with, the cement or the concrete? Although, as a policyholder representative, I would like to say that the Court should be concerning itself with the cement, I don’t think that’s right. The property which needs fixing is the concrete. The claim is not for the cost of repairing the cement, but for the cost of repairing the concrete.
On the basis of the above, although the insurer wasn’t successful in obtaining summary judgment on the proposition that the insured property hadn’t suffered damage, I expect the insurer to succeed on that issue at trial.
Is LEG3 ambiguous?
As in SCB, the Court in Archer first considered whether it was ambiguous as to whether LEG3 was an extension or an exclusion. The policyholder had argued that LEG3 is “both a coverage grant and an exclusion”, and the Court held that LEG3 “generates a functional extension, or broadening, of coverage”, as compared with the narrower exclusion which LEG3 had replaced by endorsement.
That doesn’t sound right to me, and in my view that doesn’t reflect the position under English Law. Tesco v Constable makes clear that the main insuring clause of a policy can only be widened by other clauses in the policy by using the clearest terms (and ABN Amro then gave an illustration of just how clear those terms needed to be, i.e very).
The second potential ambiguity in LEG3 was what it means to “‘improve’ the original workmanship”. Here, the Court in Archer didn’t develop the arguments any further than in SCB, and simply agreed that LEG3 was ambiguous in that regard.
So, where does that leave us?
In a few short months two different Courts, applying the law of two different States, have both held that LEG3 is ambiguous. In fact that’s being somewhat diplomatic, and it’s probably more true to say that neither Court could work out what on earth LEG3 was supposed to mean. That being the case, if SCB suggested that there was an opportunity for the LEG Committee to take a fresh look at the drafting of LEG3 and the other defects exclusions, Archer suggests that it really has no option, and that it must do so as a matter of urgency.
If LEG3 is going to be amended (as, in my view, it must), then the LEG Committee also has an opportunity to overhaul the other defects exclusions.
Although the DE clauses and the LEG clauses have different origins, it is not helpful for there to be two different suites of clauses which are so similar to each other. In my view it would be much better for there to be a single suite of clauses which captures the best elements of the current clauses.
So:
- There should be a clause which is concerned with causation, and which excludes the cost of repairing any damage caused by mistakes (which would essentially be a re-drafted, simplified, version of DE1 and LEG1, which both do the same thing);
- There should then be two clauses which are concerned with the condition of the relevant property before the damage occurs. One of those clauses would exclude the cost that would have been incurred to repair any defects which were present in property that has become damaged, if those defects had been discovered immediately before the damage occurred (i.e. a re-drafted, simplified, version of LEG2). The other clause would exclude entirely the cost of fixing damage to property which was in a defective condition immediately before the damage occurred (i.e. a re-drafted, simplified, version of DE3, which one might call LEG2A in the new suite);
- The final clause would exclude only the cost of improvements (i.e. a re-drafted, simplified, version of LEG3). My SCB article proposed an amended version of LEG3, and a few months later I would still stand behind that draft.
Those clauses would be made to be bought together. So, a policy with the most limited cover would contain only LEG1. A policy with wider cover would contain both LEG1, and also either LEG2 or LEG2A (whichever is most appropriate for the type of project involved). A policy with the widest cover would contain LEG1, plus one of LEG2 or LEG2A, and also LEG3. Where a policy contains more than one of the new defects exclusions, the policyholder should be able to choose which to apply in the event of a claim, with each exclusion coming with a different deductible. LEG1 would have the lowest deductible. LEG2 or LEG2A would have a higher deductible, and LEG3 would have the highest deductible of all.
That, in my view, would represent a very healthy outcome for insurers, brokers, and policyholders alike, and constitute a positive response to the issues raised by SCB and Archer: a single suite of defects exclusions; which are simply drafted and easy to understand; and which fit together with each other, and are intended to be used in conjunction with each other.
