    Climate Litigation More Than Doubles in Five Years

    Stockholm (NordSIP) – During recent years, the fight for a more sustainable future has often moved from the back halls of government power and the boardrooms of companies to find itself before a judge in courts of law.

    Now, a new report – Global Climate Litigation Report: 2023 Status Review by the UN Environment Programme (UNEP) and the Sabin Center for Climate Change Law at Columbia University, contextualise these events to highlight the emerging trend of climate litigation becoming an integral part of securing climate action and justice. The report is based on a review of cases focused on climate change law, policy or science collected up to 31 December 2022 by the Sabin Center’s US and Global Climate Change Litigation Databases.

    Climate policies are far behind what is needed to keep global temperatures below the 1.5°C threshold, with extreme weather events and searing heat already baking our planet,” said Inger Andersen, Executive Director of UNEP. “People are increasingly turning to courts to combat the climate crisis, holding governments and the private sector accountable and making litigation a key mechanism for securing climate action and promoting climate justice.”

    A Growing Body of Law

    The total number of climate change court cases has more than doubled since 2017, from 884 in 2017 to 2,180 in 2022, and is growing worldwide. Legal actions were brought in 65 bodies worldwide: in international, regional, and national courts, tribunals, quasi-judicial bodies, and other adjudicatory bodies, including special procedures of the UN and arbitration tribunals.

    Although the USA remains the most prolific jurisdiction where environmental cases are brought to court, about 17% per cent of cases now being reported in developing countries, including Small Island Developing States.

    According to the report, most ongoing climate litigation falls into one or more of six categories:

    1. Cases relying on human rights enshrined in international law and national constitutions;
    2. Challenges to domestic non-enforcement of climate-related laws and policies;
    3. Litigants seeking to keep fossil fuels in the ground;
    4. Advocates for greater climate disclosures and an end to greenwashing;
    5. Claims addressing corporate liability and responsibility for climate harms;
    6. Claims addressing failures to adapt to the impacts of climate change.

    According to the report, this argument matters since as climate litigation increases in frequency and volume, the body of legal precedent grows, forming an increasingly well-defined field of law.

    “There is a distressingly growing gap between the level of greenhouse gas reductions the world needs to achieve in order to meet its temperature targets, and the actions that governments are actually taking to lower emissions. This inevitably will lead more people to resort to the courts. This report will be an invaluable resource for everyone who wants to achieve the best possible outcome in judicial forums, and to understand what is and is not possible there,” said Michael Gerrard, Sabin Center’s Faculty Director.

    Climate Change and Human Rights

    The report demonstrates how courts are finding strong human rights linkages to climate change. This leads to greater protections for the most vulnerable groups in society and increased accountability, transparency and justice, compelling governments and corporations to pursue more ambitious climate change mitigation and adaptation goals.

    The report also highlights how this emerging rend is relevant for vulnerable groups who struggle to make their voice heard. 34 cases were brought by and on behalf of children and youth under 25 years old, including by girls as young as seven and nine years of age in Pakistan and India, respectively. In Switzerland, on the other hand, plaintiffs are making their case based on the disproportionate impact of climate change on senior women.

    In the future, the report predicts a rise in the number of cases dealing with climate migration, cases brought by Indigenous peoples, local communities and other groups disproportionately affected by climate change, and cases addressing liability following extreme weather events. The report also anticipates challenges in applying the science of climate attribution as well as a rise in “backlash” cases against litigants which aim to dismantle regulations that promote climate action.

    Notable Cases

    The report highlights notable cases where government decisions were challenged based on a project’s inconsistency with the goals of the Paris Agreement or a country’s net-zero commitments.

    Of these, seven particular key climate litigation cases and matters covered in the report stand out:

    1. The UN Human Rights Committee concluding for the first time that a country has violated international human rights law through climate policy and climate inaction, finding Australia’s government is in violation of its human rights obligations to Torres Strait Islanders;
    2. Brazil’s Supreme Court holding that the Paris Agreement is a human rights treaty, which enjoys “supranational” status;
    3. A Dutch court ordering oil and gas company Shell to comply with the Paris Agreement and reduce its carbon dioxide emissions by 45 per cent from 2019 levels by 2030. This was the first time a court found a private company to have a duty under the Paris Agreement;
    4. Germany’s court striking down parts of the Federal Climate Protection Act as incompatible with the rights to life and health;
    5. A court in Paris holding that France’s climate inaction and failure to meet its carbon budget goals have caused climate-related ecological damages;
    6. A United Kingdom court finding that the government had failed to comply with its legal duties under its Climate Change Act 2008 when approving its net-zero strategy;
    7. Efforts to obtain advisory opinions on climate change from the International Court of Justice and the International Tribunal for the Law of the Sea are being initiated and driven by Small Island Developing States.
