Air pollution caused by heavy transport and handling operations in industrial sites creates legal and financial risks that often remain hidden for businesses. In the Czech Republic, new European emission standards and stricter air quality limits apply to you, and they are set to start taking effect in 2026. This article will clarify what obligations actually apply to you, what sanctions you may face, and where the most common legal pitfalls lie in practice.

Pollution from transport and on-site handling – the legal reality in the Czech Republic

Heavy traffic on site roads, loading goods, handling materials, and parking vehicles – all of these activities release nitrogen oxides, particulate matter, and other harmful substances into the air. At first glance, it may seem like ordinary operations. Many assume that if vehicles have passed the technical inspection, everything is fine. The reality, however, is far more complex and stricter.

In the Czech Republic, you are currently subject to three consecutive legal regimes that impose obligations on you and expose you to sanctions. The first is civil liability, i.e., the obligation to compensate the person who has been harmed by the pollution. For example, a neighbour whose property has been contaminated.

The second is public-law liability for an administrative offence, imposed by the Czech Environmental Inspectorate or local authorities. The third is criminal liability, which applies to more serious cases and is handled by the public prosecutor and the police.

In practice, these regimes very often overlap. This means that a single pollution incident may simultaneously trigger administrative proceedings for a fine, civil proceedings for damages, and potentially also criminal proceedings. Each of these proceedings has different procedural rules, a different burden of proof, and different impacts on your business.

The attorneys at ARROWS, a Prague-based law firm, encounter this level of complexity repeatedly. They know how to proceed in each type of proceedings, how to protect your rights, and how to communicate with the authorities so that all three proceedings do not unravel at once and result in multiple layers of exposure.

The “polluter pays” principle and strict liability

The central legal principle in the field of air protection is the “polluter pays” principle. This means that whoever causes pollution through their activities bears all costs of its removal and remediation. This principle is enshrined in both European and Czech law and is entirely beyond dispute.

Moreover, many environmental offences are subject to so-called strict liability. In practice, this means that fault is not required – neither intent nor negligence. It is sufficient that the pollution occurred in connection with your operational activities and that there is a causal link between them. For how limits, permits, and the consequences of breaches are assessed in practice, you may also find the follow-up overview in the article Integrated Permit (IPPC) and emission limits: legal framework and sanctions for breaches useful. For example, if handling materials in your yard causes dust that spreads beyond the premises, you are liable for it just as strictly.

In practice, however, this leads to a common misconception: an ordinary business owner assumes that if they keep their vehicles in good condition and have a valid technical inspection, nothing can happen to them. But the legal reality is different – if a vehicle exceeds permitted emission limits during an inspection, you face sanctions regardless of your good faith. The attorneys at ARROWS, a Prague-based law firm, know these situations and can explain what exactly the inspection authorities check and what you should focus on.

Liability regardless of any breach of law

An interesting but often overlooked fact of Czech legal practice is that your liability for pollution does not cease even if you comply with all statutory obligations to the letter. In other words: even a valid operating permit, compliance with emission limits, proper payment of fees, or investments in modern technologies may not protect you from a civil claim for damages caused by your emissions.

A public-law fee for air pollution is not the same as compensation for damage under the Czech Civil Code. These are two entirely separate legal relationships. Therefore, if a neighbour’s forest or agricultural land suffers over the long term due to your emissions, the owner may claim damages even if you have always acted in compliance with the regulations. In such a case, the court examines only the causal link between your operations and the damage incurred, the amount of the damage, and the period when it manifested.

This reality confirms why it is important to approach air protection comprehensively and not rely solely on meeting the “mandatory minimum”. Our attorneys in Prague can help you set up your operations to minimise risks not only vis-à-vis state regulators, but also in relation to private-law claims by neighbours or owners of surrounding land.

New legislation in 2026 – the EU Air Quality Directive and changes to limits

In the Czech Republic, there have recently been significant legislative changes that directly affect your liability and operating costs. One of the most important steps was the adoption of the new Directive of the European Parliament and of the Council on ambient air quality and cleaner air for Europe. It entered into force at the end of 2024.

This directive is considered a revolution in the approach to air protection, not because it introduces entirely new limits, but because it introduces an enforceable approach with stricter controls and sanctions against Member States.

The Czech Republic is now undergoing the process of transposing this directive into national law. The impacts of stricter regulation on specific projects (including the risk of restricting or suspending operations) are also discussed in the article When air pollution may be a reason to stop a construction project or operations. For entrepreneurs, this means a gradual and systematic tightening of emission limits, which will continue until 2030. It is therefore high time to start reviewing your operating standards. 

New emission limits for particulate matter and nitrogen oxides

The new EU Ambient Air Quality Directive sets new target values to be achieved no later than 1 January 2030. While the current Czech legal framework and previous emission standards allowed a certain degree of tolerance, the new directive tightens these limits significantly.

Particulate matter PM10 (particles with a diameter of less than 10 micrometres) – The currently applicable Czech limit for the annual average concentration is 40 micrograms per cubic metre (40 µg/m³).

The new Directive provides that no later than 1 January 2030, the annual average concentration of PM10 must be a maximum of 20 µg/m³, i.e., a 50% reduction compared to the current limit.

The daily average concentration must not exceed 45 µg/m³, and this value must not be exceeded more than 18 times per calendar year. This is indeed a significant tightening.

PM2.5 particulate matter (particles with a diameter of less than 2.5 micrometres) – These particles are particularly harmful because they penetrate deep into the airways and lungs. The new Directive sets a new target limit of 10 µg/m³ for the annual average concentration, which is another significant tightening.

In the Czech Republic, in 2024 this limit was met at several monitoring stations, and in some cases some of the lowest values in the history of measurements were achieved. This is positive news, but it also creates new pressure to maintain these low levels on a long-term basis and requires further measures.

Nitrogen oxides (NOx) – The new EU Directive introduces a further reduction of immission limits for nitrogen dioxide (NO₂). Currently, the Czech Republic has been meeting the NO₂ limits for several years without exceedances.

Euro 7 emissions standard – With regard to the transport sector, a new Euro 7 emissions standard is being prepared, which will be the strictest standard to date and will replace the current Euro 6 (in force since 2014). Approval of the final form of the legislation is expected in 2026–2027.

Entry into force for new vehicle types is planned for 2028–2029, and the obligation for all newly sold vehicles in 2030.

Main new features of the Euro 7 standard:

  • Harmonisation of limits for petrol and diesel – until now, diesel engines had more lenient limits for certain emissions; Euro 7 changes this.
  • Regulation of emissions from brakes and tyres – for the first time in history, the standard also focuses on non-exhaust emissions, specifically brake dust and tyre wear, which make up a significant share of particulate matter in urban air.
  • Stricter testing – emissions will be measured across a wider temperature range (from −10 to +35 °C) and under various driving modes, including short urban trips when the engine is not fully warmed up.
  • Longer service life of after-treatment systems – catalysts and particulate filters must remain functional for the entire service life of the vehicle (200,000 km or 10 years).

For operators, this means that you should already start planning the renewal of your fleet today. Older Euro 6 vehicles will gradually be pushed out of the market.

Prices for new Euro 7 vehicles will be higher, and the transitional period between 2026–2030 will be the time when the last Euro 6 technology vehicles will be available, likely with high discounts.

Changes in Czech legislation and reporting obligations

In the Czech Republic, legal changes are being prepared or are already entering into force in response to the new EU Directive and the need to tighten air protection. The new rules for reporting the dates of emissions measurements and submitting measurement reports to the inspectorate are becoming stricter.

Electronic reporting with shorter deadlines is increasingly being implemented (e.g., within 24 hours of carrying out the measurement for selected types of sources, as specified, for example, by Decree No. 415/2012 Coll. and any amendments thereto).

This means that your reporting obligations are becoming stricter and you must be prepared for faster and more transparent communication with regulators.

The attorneys of ARROWS, a Prague-based law firm, can advise you on how to set up internal processes so that they comply with these new reporting obligations. It is not only a matter of an administrative filing, but also of ensuring that measurements are correct and that suspicion of manipulation is avoided.

Inspections and sanctions – what to expect in practice

The Czech Environmental Inspectorate (ČIŽP) is the state supervisory authority responsible for monitoring compliance with legal regulations in the field of environmental protection, including air protection. ČIŽP carries out inspections based on a plan or based on a complaint, for example when neighbours complain or when inspectors suspect a breach of the law.

An inspection is not random – ČIŽP focuses on three key areas where fines are statistically the highest: waste, water and air. As regards air pollution in industrial sites, inspectors focus on:

  1. Compliance with emission limits set out in the permit for operating stationary sources (e.g., boilers, furnaces, etc.).
  2. The technical condition and maintenance of combustion sources.
  3. Handling of waste and materials (if stored or processed on the site, with regard to dust and substance leaks).
  4. Operation of transport and the condition of vehicles on the site (even though the primary control of road transport lies with the Police of the Czech Republic).
  5. Fulfilment of reporting and record-keeping obligations in information systems (e.g., IRZ, ISPOP).

Vehicle inspections are carried out by the Police of the Czech Republic (especially with regard to smoke opacity and the functionality of emission systems) and by ČIŽP (with regard to stationary sources on the site and general compliance with the Air Protection Act). Emissions measurements for vehicles take place primarily as part of regular technical inspections, but also through mobile expert units of the Police of the Czech Republic directly in operation.

Inspectors and the police focus on smoke opacity, particulate matter and the functionality of emission reduction systems. If a roadside inspection reveals a dangerous defect in the area of emissions, the vehicle’s roadworthiness may be restricted on the spot or further driving may be prohibited altogether.

For the operator, the fine for a first breach may reach up to CZK 50,000 per vehicle in administrative proceedings. However, if tampering with tachographs or emission systems is proven, sanctions of up to CZK 5,000,000 may apply, including for legal entities.

For stationary sources of pollution (e.g., industrial technologies, boilers on the site, etc.), ČIŽP carries out measurements and compares them with the emission limits set out in the permit.

If an exceedance occurs, the inspectorate initiates administrative proceedings and may impose a fine ranging from hundreds of thousands to tens of millions of Czech crowns, order remedial measures, and in extreme cases also decide to restrict or suspend operations.

Real levels of fines and remedial measures

The figures we encounter in practice are alarming. The above-mentioned fines for vehicles are not the biggest problem – they are in the tens of thousands of Czech crowns. The real danger lies in fines for operational breaches on sites and the subsequent remedial measures.

When ČIŽP finds a breach of the Air Protection Act, for example that a stationary source emits more pollutants than its permit allows, or that construction or activities are carried out without the required permit, it may impose a fine of up to CZK 10 million on a legal entity.

But that is not all. Along with the fine, the inspectorate usually also orders a remedial measure, meaning that you must remedy the defect within the specified period (usually 30–90 days). A remedial measure often means installing filters, reconstructing technologies, or ordering you to reduce production capacity. In industrial sites, this involves investments in the tens to hundreds of millions of Czech crowns.

In extreme cases, ČIŽP will issue a decision to suspend operations, which for a company means a de facto collapse – you cannot sell, you cannot fulfil contracts with customers, cash flow stops.

The complexity of administrative proceedings and the risks of failure

When ČIŽP initiates administrative proceedings, you must not think it is just a formality. The proceedings are complex and have several stages. The inspectorate carries out an inspection, prepares an inspection report, and then initiates administrative proceedings based on its findings. In these proceedings, you are given the right to comment on the matter, submit evidence, propose additional evidence-taking, and subsequently file an appeal against the decision.

The most problematic part is what inspectors find during the measurement. Emissions measurements are carried out using special instruments, and even if you are confident that you are complying with your permit, it can come as a surprise when the inspection informs you that you are exceeding the limit. At that moment, you need to make very smart decisions.

The attorneys at ARROWS, a Prague-based law firm, know how to act in such situations. They can help you prepare submissions in administrative proceedings, arrange an independent measurement to challenge the inspection’s measurement, and communicate with the authorities in a way that minimizes conflict and maximizes the chances of a favorable outcome.

Related questions on air protection

1. If I am aware of an error and want to fix it myself before the inspection comes, can I avoid a fine?
Partly yes, but it depends on timing and the specific circumstances. If you report the breach to the competent public authority yourself before you are inspected, this may be considered a mitigating circumstance. In some cases (for less serious offences), you may avoid a fine, but the obligation to remedy the situation remains. 

2. What if I claim that the supplier or a hired driver is responsible for the pollution, not me as the site owner?
The liability of the site owner or its operator is not eliminated. If you operate the site, you are responsible for what happens there. If external companies or drivers work there, this does not relieve you of liability—you are still the operator. 

3. What rights do I have during an inspection and measurement by the Czech Environmental Inspectorate (ČIŽP)?
You have the right to be present during the inspection and measurement, you have the right to see the measured values, and you have the right to request a copy of the inspection report. If you believe the measurement was incorrect, you can commission an independent measurement by an external accredited laboratory—then, in the proceedings, it will be assessed which measurement is credible. ARROWS’ Prague-based attorneys can stand by you during such an inspection and protect your procedural rights.

Low-emission zones – new restrictions in urban areas

With the introduction of new emission limits and efforts to improve air quality, Czech and European cities are gradually introducing so-called low-emission zones (also referred to as environmental zones or LEZ – Low Emission Zones). In these zones, vehicle entry is restricted according to their emission category. Older and more polluting vehicles are not permitted to enter.

The principle of low-emission zones and the rules in the Czech Republic

Low-emission zones are legally anchored in Act No. 201/2012 Coll., on Air Protection. The Act allows municipalities to establish low-emission zones, and if such zones are introduced, vehicles that do not meet the emission categories for entry and do not have an exemption are not permitted to enter, under threat of a fine.

In the Czech Republic, low-emission zones are being introduced gradually. While in some large cities (such as Prague) they have already been introduced or are being prepared, in smaller towns they are still only being discussed. However, it can be expected that the number of cities with a low-emission zone will increase, especially if new EU limits begin to be applied.

If a zone is introduced where you operate, you may face the following situation: your older vehicles (for example, a truck or a diesel car from 2000–2010) will not be allowed to enter this zone without an emissions sticker. Without a sticker, or with an incorrect sticker, a police officer or municipal police officer may impose a fine.

Examples from abroad – Germany and the outlook for the Czech Republic

A good example of how low-emission zones work is Germany, where there are currently (2026) more than 80 environmental zones covering major cities as well as entire areas.

In Germany, such a zone is called an Umweltzone, i.e., an environmental zone. All vehicles may enter an environmental zone in Germany only with an emissions sticker (Umweltplakette or Feinstaubplakette). The sticker is color-coded to correspond to the vehicle’s emission category.

A green sticker is for the cleanest vehicles, a yellow one for older categories. Vehicles that cannot obtain even a yellow sticker (typically vehicles older than 1990 without sufficient emissions technology) are not permitted to enter the zone at all.

If you enter an environmental zone without a German emissions sticker, or with an older yellow sticker where a green one is required, you will be fined approximately EUR 100. But beware—if the police suspect that your car is not in good technical condition (for example, it is excessively smoking from the exhaust), they may stop you and recommend that you go to a service center where emissions will be measured.

If you do not meet the prescribed emission standard, you must have the car repaired on the spot or towed back to the Czech Republic. In such a case, the emissions sticker will not save you, and you will still pay a fine.

A similar expansion of low-emission zones can also be expected in the coming years in the Czech Republic. If you have a fleet and commute to major cities, you should take their emission category into account when purchasing new vehicles. Investment in fleet renewal will gradually become a necessity.

Exemptions and special regimes

The Air Protection Act provides that a municipality may grant an exemption in a low-emission zone to certain vehicles or groups of vehicles. For example, vehicles used by persons with disabilities, emergency service vehicles, or vehicles that are necessary for the operation of industry in the given area. Such exemptions are granted upon application and are subject to thorough review.

If your activities on the site or your vehicles may fall under an exemption, you should proactively communicate with the local municipality and find out what options are available. ARROWS’ Prague-based attorneys can help you prepare the exemption application and negotiate with the local authorities.

Practical risks and typical situations from business practice

In industrial sites, we encounter the following typical situation: Several dozen vehicles enter the site every day (trucks, handling equipment, employees’ cars). There are also stationary sources of pollution on the site—boilers, furnaces, handling machinery. The site operator clearly has the right and the duty to control what happens there, but in practice there is often a lack of awareness of the legal liability they bear.

Key legal rules that apply to the chain of liability:

  1. The “polluter pays” principle – the person whose activity causes pollution bears the costs of its removal. If you are the site operator, even if the pollution was caused by a vehicle of an external supplier, you may be fined. You can then seek recourse (compensation from the vehicle owner), but you are liable vis-à-vis the public authority.
  2. Strict liability – you do not need to be at fault; it is sufficient that the pollution arose in connection with your activity.
  3. Liability regardless of a breach of law – even if you have all permits and comply with emission limits, you may still be held liable in private-law proceedings for damage to the surrounding area.

Potential issues

How ARROWS helps (office@arws.cz)

Fine for exceeding emission limits or operating without a permit – the Czech Environmental Inspectorate (ČIŽP) may impose a fine of up to CZK 10 million and order remedial measures.

Administrative defence – we will represent you in misdemeanour proceedings, submit a motion to review the Inspectorate’s measurements, and arrange independent measurements to challenge the ČIŽP results. We will assist with an appeal against the decision.

Shutdown of operation of a stationary source – a decision to suspend operation of a pollution source until remediation is arranged can mean the de facto collapse of the business.

Crisis management – we will immediately file an appeal or a motion for interim relief and negotiate with ČIŽP on a phased solution, minimising the duration of the operational interruption.

Private-law claim by neighbours for damages – neighbours may claim compensation for pollution of their property regardless of your misdemeanour.

Civil dispute – we will represent you in court proceedings and argue causation, the amount of damage, and your fault, with the aim of minimising your liability.

Lack of an emergency plan and communication with regulators – lack of awareness of obligations and poor communication with ČIŽP leads to further burden.

Compliance and prevention – we will review your internal policies, emergency plans and communication protocols with regulators so that you are always prepared.

New initiatives and future developments – what to prepare for

The European Union is moving towards further tightening in the area of air quality. The new EU Ambient Air Quality Directive means that Member States will have to adopt more precise measures and will be subject to closer oversight. Over the next 3–4 years, the Czech Republic will have to focus on meeting new immission limits, which are set higher through to 2030.

Further developments are already being prepared in the automotive sector as well. The Euro 7 standard, which will take effect in 2028–2030, will require a range of investments from vehicle manufacturers. For businesses, this means that the prices of new vehicles will increase. Older vehicles will gradually be pushed out of the market and low-emission zones will expand.

We recommend that you already consider a long-term strategy for fleet renewal and technology modernisation. ARROWS attorneys in Prague can help you map your legal obligations and prepare a strategic plan so that legislative changes do not come as a surprise, but as an anticipated and managed change.

Final summary

Air pollution from transport and handling activities in industrial premises is a very serious legal and financial topic. If you do not take it into account now, you may face several unpleasant surprises over the next 2–3 years. New emission limits, the new EU Directive and the Euro 7 standard are not just theoretical discussions – these are specific legal obligations that will be enforced.

Strict liability of the operator means that you do not have to act at fault – it is sufficient that the pollution arises in connection with your activity. A fine for exceeding limits can reach tens of millions of Czech crowns, and even worse are remedial measures and shutdowns, which can mean the de facto collapse of the business.

FAQ

1. If my vehicle has a registration certificate and passes the technical inspection, am I compliant with emissions?
No. The registration certificate and technical inspection are minimum standards. If, in real operation, the vehicle emits pollution measurably above the limit value, you are liable regardless of the registration certificate. ČIŽP and the Police of the Czech Republic (Policie ČR) carry out measurements directly in operation and may find that the vehicle smokes more than it should. ARROWS attorneys in Prague can advise you on what level of care to devote to your fleet and how to minimise the risk.

2. What are my obligations as an operator of a site if external contractors work there?
As the site operator, you are responsible for what happens on the premises. If an external company handles polluting material there or brings in old vehicles that smoke, you may be fined. Therefore, your contractual terms should clearly define the external company’s responsibility and you should require them to meet emission standards. ARROWS attorneys in Prague can prepare such contracts for you.

3. How much does remediation cost if ČIŽP finds pollution and orders remedial measures?
It varies significantly. A simple remedial measure (e.g., repairing ventilation in a hall) may cost tens of thousands of Czech crowns. More complex measures (e.g., installing filters, reconstructing technologies, or renewing the fleet) are counted in millions to tens of millions. The most expensive are remedies in cases where ČIŽP orders a shutdown – then losses in turnover and contractual performance are taken into account.

4. Can I order an emissions measurement myself in advance to see whether I am compliant?
Absolutely. We recommend ordering an independent measurement from an accredited entity. If the results are good, you at least have certainty. If they are worse, you have time to remedy the situation before the inspection arrives. ARROWS attorneys in Prague can advise you on which entity is credible and how to interpret the measurements correctly.

5. What is the minimum I have to do to reduce the risk of fines?
Focus on five key areas: (1) proper fleet maintenance and regular emission checks, (2) technical dust-control measures on the premises (watering, protective tarpaulins, extraction), (3) regular review of permits and compliance with emission limits for stationary sources, (4) employee training on environmental obligations and correct procedures, (5) a long-term plan for renewing vehicles and technologies with regard to new standards. ARROWS attorneys in Prague can prepare a more detailed compliance programme for your specific situation.

6. How do the low-emission zones that cities are currently introducing differ from existing obligations?
Low-emission zones are an additional restriction – if such a zone is introduced where you operate, your vehicles may not be permitted to enter without an emissions sticker or if they do not meet the required emissions class. This is another layer of restrictions on top of existing obligations. If you have an old vehicle that does not meet the zone’s requirements, you will not be allowed to enter the zone. Therefore, it is a good idea to map already now which cities are introducing such zones or plan to introduce them.
