A group of Dutch citizens weary of ineffectual climate diplomacy are celebrating after forcing change through legal action. Last week, following a lawsuit filed by a citizens’ climate-change platform called the Urgenda Foundation, a court in The Hague ordered the government of the Netherlands to cut greenhouse-gas emissions to at least 25% below 1990 levels by 2020 — substantially greater cuts than are required under the small country’s European Union (EU) obligations.
The ruling could encourage citizens of other countries to try using legal avenues to force stricter climate policies, says James Thornton, the London-based chief executive of Client Earth, an international group of environmental lawyers. “This is a very powerful decision with possible far-reaching repercussions,” he says. “It is forcing the use of undisputed scientific results for responsible policy-making — a very remarkable step.”
The Dutch government may still appeal the ruling, and even if it does have to implement extra emissions cuts, these would barely dent global greenhouse-gas emissions. But the court made clear that although Dutch policy-makers can do little to reduce emissions in China or the United States, they still have an obligation to act out of a duty of care for their citizens.
Thornton hopes that other courts will judge similar lawsuits in the same way in future. One such case is pending in Belgium, which must reduce its emissions by only 15% below 2005 levels under current EU pledges. But it is unclear whether the landmark Dutch ruling, and any European lawsuits that might follow, will make waves in other parts of the world — particularly in the United States.
In 2007, the US Supreme Court authorized the Environmental Protection Agency (EPA) to regulate greenhouse-gas emissions that contribute to air pollution, because pollution could endanger public health or welfare. A series of greenhouse-gas reduction plans have followed. But attempts to get federal courts to order more-substantial cuts have so far come to nothing. Four years after the EPA decision, the Supreme Court rejected an effort by California and five other states to seek a cap on emissions from the utilities sector. The states argued that greenhouse gases are a ‘public nuisance’; however, the court countered that the EPA’s authority to regulate emissions prevented federal judges from using the public-nuisance argument. Attempts by others to claim liability against polluters and seek damages under civil law have also been unsuccessful.
In the United States, “there is no federal constitutional right to environmental protection”, says Richard Stewart, an environmental-law specialist at New York University. “Some state courts may recognize such a right, but the remedy might at best be limited to local sources.”
“This is a very powerful decision with far-reaching repercussions.”
That seems to be the case in Washington state, where on 23 June, a Seattle court ordered the state’s ecology department to reconsider a 2014 petition brought by eight school students to limit the state’s carbon dioxide emissions. The petition called for the agency to act in line with what scientific evidence says is needed to protect the climate and the environment. The agency initially denied the petition, but has been ordered to report back to the court by 8 July. Petitioners’ lawyer Andrea Rodgers, of the Western Environmental Law Center in Seattle, said that it was the first time a US court had ordered a state agency to consider the most current and best available climate science in deciding regulation on carbon emissions.
It would be unusual for a US court to demand a specific level of federal emissions regulation, as has happened in the Netherlands, says Michael Oppenheimer, who studies geosciences and international affairs at Princeton University in New Jersey. A court would be likely to do so only if there were a large gap between public safety and existing regulations, he says.
“If it became clear that US regulations, along with actions of other countries, are insufficient, then at some future date a court might invoke the objective to force stronger action,” he says. But, adds Oppenheimer, current US targets are consistent with “at least some pathways” that would keep the world’s warming below 2 °C, the internationally recognized threshold for ‘dangerous’ climate change.
