Czech Climate litigation

WHAT IS THE CZECH CLIMATE LITIGATION?

The association Czech Climate Litigation brings together more than 450 people from across the Czech Republic who are concerned about the state’s inaction on climate protection. 
We come from different corners of the country and different professional backgrounds.
Our members include students, people from the private sector, agriculture and forestry, medicine, education, and many other fields.

OUR JOURNEY FOR JUSTICE

Together with law firm Frank Bold Advokáti, the Czech Climate Litigation association and other individuals affected by the climate crisis filed a lawsuit against the responsible ministries and the Czech government. We drew on expert evaluations according to which the state is not taking sufficient measures to reduce emissions (mitigation) or to adapt to ongoing changes. Through this approach, the state is violating our human rights and international commitments. The goal of our efforts is to push for more ambitious and effective measures.

Q&А

If we win in the court, the government will have a legal duty to start taking climate change seriously and accept appropriate mitigation and adaptation measures. Even if we do not win, the lawsuit will support a debate at national and regional level on the adequacy of current measures. In fact, just the court filing and its media coverage itself can influence top politicians to start taking the situation seriously and to take stronger action to combat climate change.
 

Although the government is providing some action plans, legislative proposals, subsidies, etc., everything is desperately insufficient and greenhouse gas emissions in Czech republic have even risen in recent years. The fight against climate change is not like the fight against other negative phenomena – poverty, crime, corruption, etc. If, according to the IPCC international expert panel, we do not take drastic measures in the next 10 years, there will be no going back. The climate litigation calls for the measures taken by the Czech Republic to be brought into compliance with the objectives of the Paris Agreement. In practice, this means substantially increasing ambitions for reducing greenhouse gases (here and now, not making vague plans for 2050) and at the same time starting to really prepare for the negative effects of climate change at all levels using nature-friendly practices (even though large farming or construction corporations will be against this).

In general, the lawsuit claims that our rights have been violated (fundamental human rights and other subjective rights) by inaction or even illegal interference by the state authorities. In addition the lawsuit claims that the Czech government breaks several international agreement by its inaction. The defendants are the Ministry of Environment, the Ministry of Commerce, the Ministry of Agriculture, the Ministry of Transport and the Czech Government. The complete text of the lawsuit (in Czech) is available here.

The lawsuit is mainly financed by members of the association and individual donors. We have also received a financial grant from the Center for Climate Integrity, which will help us cover the cost of the lawsuit. The income and expenses of the association are public and available for viewing on the transparent account of the association.

If we win, the court can order the government to:

  1. Refrain from actions which would obviously jeopardize the fulfillment of the Czech Republic’s commitments in protection against climate change (e.g. by granting emission exemptions to the largest CO2 producers),
  2. Update the Climate protection policy and other government plans into compliance with Czech international commitments,
  3. Update its Nationally Determined Contribution to the Paris Agreement in a way that avoids dangerous climate change,
  4. Align its climate protection instruments (e.g. grant programs) with its policy documents and to strengthen climate adaptation measures,
  5. Compensate victims of climate change (small farmers, owners of forests, etc.) and assist them in implementing necessary measures.

If successful, the lawsuit will provide a strong signal to government agencies to be more consistent in protecting Czech citizens from climate change, and an important precedent for similar cases in our country and abroad. The Czech Climate Litigation association will then oversee government compliance with the obligations imposed by the court.

In case the lawsuit will be dismissed at the Municipal Court in Prague, we will turn to the Supreme Administrative Court and afterwards also possibly to the Constitutional Court. However, the Czech legal system provides relatively limited means of protecting our rights related to the climate crisis. Even if we use all available legal means with the best available expertise, it is still possible that the case will be dismissed. That however does not indicate that the case is not legitimate; there is no doubt about its legitimacy. Dismissal of the lawsuit would only indicate that we have failed to enforce our rights and legitimate claims through the courts. Nevertheless, the filing of the lawsuit itself can yield some results:

  1. A negative judgment may still include a partial acknowledgment of our claims,
  2. We will raise awareness about the climate crisis and the government’s responsibility to combat its causes and manifestations among the general public.
  3. Even in the event the case is dismissed, the government becomes aware of its obligations and also of the fact, that there is a substantial group of people who are determined to assert their rights through the courts.
  4. Regardless of the outcome, civil society is mobilized in the preparation of the lawsuit, with valuable friendships and alliances being formed between people who feel responsible for our common future.

Yes, the basic function of the court system is to protect the rights of citizens. If someone violates or threatens our rights, the court can order them to stop, whether it is the Government itself or one of its ministers. And because the state has not only the obligation not to harm citizens and nature, but also to actively protect them under international and constitutional law, the court can order the state to fulfil its legal obligations within a certain period. However the court cannot decide on policy measures themselves or order the state to take a specific measure (e.g. to provide a specific amount of subsidy for specific persons).

Current status

Our efforts at the Czech courts were unsuccessful (odkaz na ten factsheet?). We have therefore decided to turn to the European Court of Human Rights (ECHR) in Strasbourg. We will file our application in February 2026. We are convinced that the right to a healthy environment is a fundamental human right that we must defend at the international level as well.

THE JOURNEY OF THE CZECH CLIMATE LITIGATION: FROM THE FIRST FILING TO STRASBOURG

The story of our lawsuit began in April 2021, when we filed a lawsuit against the government and the relevant ministries in cooperation with law firm Frank Bold Advokáti. The reason was insufficient measures to reduce emissions (mitigation) and to adapt to climate change (adaptation). We demanded that the state take steps that would genuinely protect our future.

FIRST VICTORY AND THE STATE'S SUBSEQUENT INACTION

In June 2022, the Municipal Court in Prague issued a landmark judgment. It sided with us on mitigation and ordered the ministries to adopt a more ambitious target: reducing emissions by 55% by 2030, in line with EU regulation. On the question of adaptation, however, the court found no breach of the law, and also acquitted the Czech Government as a whole. 

Even though the judgment was final and binding, the ministries did not comply with it and took no additional measures, thereby disregarding the court’s decision. Unfortunately, the Czech legal system offers no protection against ministries ignoring an administrative judgment.

THE LEGAL BATTLE AT A HIGHER INSTANCE

In February 2023, the Supreme Administrative Court (SAC) overturned the original judgment and returned the case for further consideration. According to the SAC, there is no legal obligation requiring Czech ministries to further reduce emissions, even though Czech climate policy is „on the edge of legality.“ The SAC considered European and international commitments to be too general. The expert evaluations calling for even deeper emission reductions failed to convince the court. The Municipal Court in Prague, bound by the SAC’s opinion, subsequently dismissed our lawsuit in October 2023.

THE END OF THE ROAD IN THE CZECH REPUBLIC

A definitive conclusion to the proceedings before the general courts came when the SAC dismissed our lawsuit in November 2024. In doing so, the court refused to follow the then-recent and landmark judgment of the European Court of Human Rights in the case of the Swiss senior women.

Believing that the fundamental human rights of people living in the Czech Republic continue to be violated, we filed a constitutional complaint in February 2025. However, the Constitutional Court dismissed it in November 2025, while not ruling out the possibility of future climate lawsuits succeeding.

None of the Czech courts stated that the Czech state was doing enough to protect the climate or fulfilling its obligations. At a time when Czechia may have exhausted its carbon budget and the effects of the climate crisis are intensifying, the courts focused on procedural criteria rather than human rights.

THE NEXT STEP: THE EUROPEAN COURT OF HUMAN RIGHTS

We have exhausted all domestic legal remedies, but our efforts are not over. We are currently preparing an application to the European Court of Human Rights, which we plan to submit in February 2026. We believe that the international court will confirm what the Czech courts overlooked: that climate protection is an essential condition for protecting the human rights of us all. And that this places clear obligations on the state to protect its citizens and future generations.
