Environmental liability insurance

The one class where the statute requires not compensation but remediation: returning the environment to its previous state, whatever it costs and whether or not anybody claims.

01Overview

What it is

Environmental liability works on a different logic from the rest of the programme. Under general liability, somebody is harmed, they claim, and the policy indemnifies. Here the duty falls on the operator and the duty is to remediate: to return natural resources to the state they were in, even where there is no injured third party claiming and even where the cost far exceeds the value of the land affected.

The second difference is that the statutory obligation is to hold a financial guarantee, not insurance. Article 24 of Law 26/2007 requires operators of the activities listed in its Annex III to hold a guarantee enabling them to meet that liability, and the guarantee may take the form of a policy, a bank guarantee or a technical reserve. The minimum amount is set by the competent authority according to the intensity and extent of the damage the activity may cause.

Environmental liability does not fit the logic of the rest of the programme, and conflating them is what leaves many companies exposed. Under general liability there is an injured party who claims and an insurer who indemnifies. Here there is an operator obliged to remediate: to return natural resources to the state they were in, through primary, complementary and compensatory measures, even where nobody claims anything.

That duty is measured not by the value of the asset affected but by the cost of the works needed to restore it — and it is precisely what general liability policies exclude.

The obligation is to hold a guarantee, not to buy insurance

Law 26/2007 on environmental liability provides in article 24 that operators of the activities listed in its Annex III must hold a financial guarantee enabling them to meet the environmental liability inherent in their activity. That guarantee may be a policy, a bank guarantee or a technical reserve, and its minimum amount is set by the competent authority according to the intensity and extent of the damage the activity may cause.

Article 28 is the one worth reading before quoting anything, because it lists the exemptions:

  • Operators whose activities could cause damage whose remediation is assessed at less than €300,000.
  • Those between €300,000 and €2,000,000 who evidence, through a certificate from an independent body, permanent and continuous adherence to the EU eco-management and audit scheme (EMAS) or to the current UNE-EN ISO 14001 standard.
  • The use of certain plant protection products and biocides for agricultural and forestry purposes.
  • Activities established by regulation on account of their low potential for damage.

Working out which of those the installation falls into is the first job, and it frequently changes the conversation entirely.

Where the gaps open up

The first is the date the damage began. In gradual pollution it is almost never clear, and which policy responds turns on it. Without pre-existing conditions cover and without a prior site study, a finding in due diligence ends up negotiated into the price of the deal.

The second is the scope of remediation. Many companies assume the exposure is the value of the land, and it is not: it is the cost of the restoration measures, which can be a multiple of it.

The third is mitigation costs. The statute requires urgent measures where damage is imminent, before any damage even exists. That outlay is immediate, and not every policy covers it with the same headroom.

Why through a broker

As a brokerage registered with the Spanish insurance regulator, the Dirección General de Seguros y Fondos de Pensiones, under reference J0140, New Brokers acts on the client's mandate, not on any insurer's behalf.

In this class the work starts with a question that is not about insurance: whether the activity sits in Annex III and whether an exemption reaches it. Answering it properly avoids buying more than necessary and, above all, avoids discovering late an obligation that is free-standing and prior to any loss. From there, it is a market with limited capacity where the technical information taken to it — soil characterisation, inventory of substances, distance to watercourses — weighs as much as the risk itself.

02Covers

What is covered

  • Primary remediation of environmental damage

    The cost of returning natural resources and the services they provide to their baseline condition, which is the central duty the statute imposes.

  • Complementary and compensatory remediation

    The measures required where primary remediation does not fully restore, or to compensate interim losses until the environment recovers.

  • Gradual pollution of soil and water

    Damage occurring progressively rather than through a sudden event. It is the exposure general liability policies expressly exclude.

  • Sudden and accidental pollution

    A discharge, leak or one-off emission, including one arising from a breakdown or an accident in the operation.

  • Prevention and mitigation costs

    Urgent measures to stop imminent damage from occurring, which the statute requires be taken even before any damage exists.

  • Damage to protected sites and biodiversity

    Harm to habitats, species and waters within the scope of the rules, whose remediation is valued on technical rather than market criteria.

  • Third-party pollution liability

    Claims by private parties for personal injury or property damage arising from the pollution event, distinct from the duty to remediate owed to the authority.

  • Defence and administrative proceedings costs

    The cost of taking part in the file opened by the competent authority, which starts long before any civil claim exists.

  • Investigation and quantification of damage

    The technical studies needed to establish the extent, the origin and the date of the damage, which in gradual pollution is the most disputed item of all.

  • Pre-existing conditions and historical liability

    Contamination pre-dating inception, covered only where expressly bought and normally after a site characterisation study.

This table sets out the regime established by Law 26/2007 on environmental liability, not the terms of any particular policy. The exemption in article 28(b) requires evidencing, through a certificate from an independent body, permanent and continuous adherence to EMAS or to the current UNE-EN ISO 14001 standard. The scope of each section is governed in every case by the specific conditions of the policy.

04Scope

What is not covered

In this class the exclusions turn on a question that is hard to answer years later: when exactly did the contamination begin.

  • Contamination pre-dating inception, unless pre-existing conditions cover is bought after a site characterisation study.

  • Deliberate breach of the environmental permit or of authorised discharge and emission limits.

  • Administrative fines and penalties imposed on the operator, as distinct from the cost of remediating.

  • Damage arising from installations operating without the environmental permit they require.

  • The cost of improvements and upgrades the authority imposes going forward, as opposed to remediating damage already caused.

  • Loss in land value beyond the cost of decontaminating it.

  • Damage caused by waste handed to an authorised manager, once title has validly passed.

  • Damage arising from undeclared activities or from substances other than those notified to the insurer.

05Use cases

When you will be asked for it

  1. Contaminated soil found during a sale

    Due diligence ahead of selling a warehouse detects hydrocarbons in the subsoil. Nobody knows whether the discharge belongs to the current activity or to the previous one.

    What it means

    The date the damage began decides which policy responds, if any does. Without pre-existing conditions cover and without a prior site study, the cost of decontamination ends up being negotiated into the price of the deal rather than with an insurer.

  2. Accidental discharge into a watercourse

    A tank failure causes a discharge reaching a watercourse, and the river basin authority opens a file and demands immediate measures.

    What it means

    Three things operate at once: mitigation costs, which the statute requires be incurred immediately; remediation of the damage to the resource; and defence in the administrative proceedings. Only the third resembles a classic liability claim.

  3. Annex III activity with no guarantee in place

    The company appears in Annex III of the statute and has neither provided a financial guarantee nor evidenced that it is exempt.

    What it means

    The first cost is not the damage, it is the breach: the guarantee is a free-standing obligation. Checking whether the installation falls within Annex III, and whether any of the article 28 exemptions reaches it, comes before any quotation.

06Process

How it is arranged

  1. Checking Annex III and the exemptions

    We establish whether the activity appears in Annex III and whether any article 28 exemption applies, starting with the potential damage threshold and with EMAS or ISO 14001 certification.

  2. Site and history analysis

    We review present and past use of the land, any characterisation studies available, and proximity to watercourses, aquifers and protected sites, which is what drives how the damage is valued.

  3. Sizing and placement

    We work from risk scenarios and their associated remediation costs, which is the method by which the amount is set, and compare wordings in a market with limited capacity.

  4. Issue, evidencing and monitoring

    We issue the policy, help evidence the guarantee to the competent authority where required, and update cover if the activity or the site changes.

08Common questions

Frequently asked questions

Is environmental liability insurance compulsory in Spain?

The statute does not require buying insurance, it requires holding a financial guarantee, and only from operators of the activities listed in Annex III of Law 26/2007. That guarantee may take the form of a policy, a bank guarantee or a technical reserve. Article 28 also sets exemptions: operators whose activities could cause damage whose remediation is assessed below €300,000 are outside it, as are those between €300,000 and €2,000,000 who evidence, through an independent body's certificate, permanent adherence to EMAS or to the current UNE-EN ISO 14001 standard.

Doesn't my general liability policy already cover pollution?

Only in part, and rarely the part that matters. General liability policies usually cover sudden and accidental pollution towards third parties, but exclude gradual pollution and, above all, the duty to remediate ecological damage owed to the authority. That remediation duty is the one that can reach disproportionate figures, and it is exactly what this policy covers.

What is the difference between indemnifying and remediating?

It is the key to this class. Indemnifying means compensating someone who has suffered damage and claims for it. Remediating means returning the natural resource to its previous state, through primary, complementary and compensatory measures, regardless of whether any third party has been harmed. Which is why the cost is set not by the value of the asset affected but by the works needed to restore it.

How is the amount of the guarantee calculated?

Article 24.2 provides that it is set by the competent authority according to the intensity and extent of the damage the operator's activity may cause, following the method to be established by regulation. That method works from risk scenarios and the remediation costs associated with each, not from turnover or company size.

Does the policy cover contamination that existed before inception?

Only where pre-existing conditions cover is expressly bought, and normally after a site characterisation study. It is the most delicate delimitation in this class, because in gradual pollution the date damage began is rarely clear, and which policy responds turns on it. It is worth settling at inception, not when the soil report arrives.

What information do you need to prepare a proposal?

A description of the activity and whether it falls within Annex III, the environmental permit if you hold one, the inventory of substances and tanks, any soil characterisation studies available, proximity to watercourses and protected sites, and any EMAS or ISO 14001 certification, since it may give rise to an exemption.
