Climate litigation moved from the courtroom to real-world impact in 2025. Across continents, judges blocked polluting projects, exposed misleading climate claims, and forced governments to rewrite weak climate plans. These cases did not rely on complicated language or distant promises. Instead, courts focused on facts, fairness, and the harm caused by unchecked pollution.
Ten years after the Paris Agreement, climate litigation has become one of the strongest tools for climate protection. Below are 13 major climate litigation wins from 2025, explained clearly and simply, while staying true to what courts actually decided.
Fossil fuel approvals overturned after courts count real emissions
Courts around the world made it clear in 2025 that fossil fuel projects cannot escape climate responsibility. Judges repeatedly ruled that governments must consider the pollution created when oil, gas, and coal are burned, not just when they are extracted.
At the start of the year, a court ruled that approval for two major oil and gas projects in the North Sea was unlawful. Regulators failed to assess emissions caused by burning the fuel. As a result, the approvals collapsed. This decision sent a strong message that climate harm does not stop at national borders or production sites.
Soon after, a proposed coal mine in northern England lost its planning permission. Once authorities properly assessed the climate impact, the project could not meet legal standards. The company behind it later abandoned the mine entirely.
In Australia, a court annulled approval for the largest coal mine expansion in one state. The ruling highlighted a major failure by regulators. They ignored emissions released when coal is exported and burned overseas. Judges stressed that these emissions still worsen climate change and must be included in assessments.
Norway followed a similar path. A court declared licenses for three offshore oilfields illegal because climate impacts were not fully studied before approval. While production was not immediately halted, the government received a strict deadline to correct the flaws.
Meanwhile, years of legal pressure finally ended plans for Brazil’s largest proposed coal power plant. Courts had already suspended permits over climate and licensing violations. By early 2025, the company withdrew, stating the project was no longer viable.
In Kenya, a decade-long legal battle ended with a court upholding the cancellation of a coal plant license. Judges found serious gaps in environmental reviews, weak public consultation, and a failure to assess climate impacts properly.
Together, these cases showed a clear shift. Courts no longer accept incomplete climate assessments. Governments must now fully measure the damage caused by fossil fuels before approving projects.
Greenwashing claims collapse under legal scrutiny
While some cases stopped pollution at the source, others tackled how companies talk about climate action. In 2025, courts and regulators challenged misleading environmental claims, also known as greenwashing.
In Australia, an energy company settled a lawsuit over claims that its electricity and gas products were “carbon neutral.” The case showed that carbon offsets were used without cutting real emissions. As part of the settlement, the company admitted offsets cannot undo climate damage and issued apologies to hundreds of thousands of customers.
In Germany, a court ruled that a global technology company could not describe a smartwatch as “carbon neutral.” Judges found that the claim relied on short-term tree projects that did not guarantee long-term climate benefits. Soon after, the company removed similar claims from marketing in other countries.
France also delivered a strong decision. A court ruled that a major fossil fuel company made misleading claims about reaching net-zero emissions while continuing large-scale oil and gas production. Judges stated that vague climate promises without clear explanations could confuse consumers.
In the United States, greenwashing cases reached the food industry. One major meat producer agreed to a large settlement after being accused of misleading customers about emissions reductions. The company paid over a million dollars and committed to changing how it markets environmental claims.
Soon after, another meat company agreed to stop promoting beef as climate-friendly and dropped its net-zero advertising. These cases reinforced a simple rule: climate claims must reflect real action, not marketing language.
Governments forced to rewrite climate plans through legal action
Climate litigation in 2025 also pushed governments to strengthen climate policies. Courts made it clear that weak plans and vague promises no longer meet legal standards.
In the United Kingdom, a high court ruling forced the government to publish a tougher climate strategy. Judges found earlier plans lacked detail and failed to explain how emissions would actually fall. The revised plan included clearer measures for energy, transport, homes, agriculture, and industry.

In the United States, young residents challenged their state over transport systems that increased emissions. The case ended in a settlement that recognized the right to a life-supporting climate. The state then released a detailed roadmap to cut emissions from roads, shipping, and inter-island flights. The plan included electric vehicles, better public transport, and native reforestation.
International courts also shaped climate law in 2025. Two global judicial bodies issued advisory opinions stating that people have a right to a healthy climate. They also confirmed that countries must prevent climate harm and could face legal responsibility if they fail.
Although these opinions do not directly force action, courts worldwide already cite them in climate cases. They strengthen the legal argument that climate protection is a duty, not a choice. Germany also became a key legal battleground. Although a court rejected one climate damages claim, it confirmed that the law can hold large polluters responsible for their share of climate harm. Later in the year, new lawsuits emerged using this legal foundation.
Across 2025, these 13 climate litigation wins reshaped how courts treat pollution, promises, and public responsibility. Judges blocked coal plants, questioned oil licenses, exposed false climate claims, and compelled governments to act within the law. Each ruling reinforced the same principle: honesty, accountability, and full climate impact assessments are no longer optional under the law.
