Greenpeace and the Law

“Lawyers can and do make a difference in campaigns to protect the planet. We advocate for fundamental rights including freedom of expression, access to information and the right to peaceful protest. We use strategic litigation to enforce environmental laws and hold both governments and corporations to account. We remind lawmakers of the legitimacy of environmental interests and the right to seek access to environmental justice.”
– Jasper Teulings, former General Counsel, Greenpeace International.

Strategic Litigation

Greenpeace’s global network of independent national and regional organisations are key players in proactive litigation worldwide to respond to environmental problems and human rights harms.

People v Arctic Oil:
In 2016, Greenpeace Nordic partnered with Nature and Youth to file a legal case against the Norwegian Ministry of Petroleum and Energy. They invoked the Norwegian Constitution, international human rights and environmental law, climate science and the Paris Agreement in challenging the government’s decision to license new oil and gas drilling in the Arctic. The seniors group, Grandparents Climate Action, led by a former Norwegian Supreme Court Justice and Friends of the Earth Norway have joined as intervenors.

The case was argued before all instances in Norway. Before the Oslo District Court, there was a partial victory for the Plaintiffs as the Court rejected the government’s contention that the environmental article in Norway’s Constitution does not confer a legally enforceable right. However, it held that Norway’s government has no power to prevent GHG emissions from oil and gas produced in Norway but burned abroad.  This finding was reversed in the Court of Appeal judgment in 2020. Although the Court of Appeal ruled for the Norwegian government, it reaffirmed the right to a healthy environment and  stated that in establishing whether the government has infringed on this right, all greenhouse gas emissions from Norwegian oil exported abroad must be taken into account. 

Due to the COVID-19 pandemic restrictions, the Norwegian Supreme Court sat in plenary and heard oral arguments via video-link over the course of seven days.  It handed down its judgment in a 11-4 ruling against the co-plaintiffs at the end of 2020. The Supreme Court departed from the lower court’s finding that there was an enforceable right to a healthy environment in the Norwegian Constitution, finding instead that it was a legal construction between a right and a principle. However, in the majority and minority opinion, the Supreme Court found that climate impacts in an environmental impact assessment should include all greenhouse gas emissions of combustion (even after export). The difference in opinions being the timing, with the dissent finding that a later assessment of these climate impacts would be insufficient according to the law.

Greenpeace Southeast Asia and others v Carbon Majors:
In 2018, the Commission on Human Rights of the Philippines started hearing a petition seeking to hold the investor-owned “Carbon Majors” (oil, natural gas, coal and cement companies) accountable for contributing to global emissions of GHGs fuelling climate impacts resulting in human rights harms. This is the world’s first national human rights investigation of its kind, brought by a coalition of 14 organisations, including Greenpeace Southeast Asia-Philippines, along with Filipino farmers, fisherfolk, human rights advocates, typhoon survivors, artists and concerned citizens. The petition was filed after super typhoon Haiyan wreaked havoc in the Philippines in 2013 and is grounded in research linking  a large share of global climate pollution to a small number of coal, oil, and gas and cement producers, known as the Carbon Majors.

The National Inquiry conducted by the Commission on Human Rights has become one of the most significant repositories of scientific, legal, and community evidence of fossil fuel industry’s responsibility for climate change impacts  and human rights harms. The Commission held hearings throughout 2018 in the Philippines, New York City, and London as part of its investigation. It received various testimonies from community representatives, prominent climate scientists, and legal and policy experts. The evidence is available to the public on the websites of Greenpeace Southeast Asia-Philippines and the Commission on Human Rights of the Philippines.

The Commission is expected to deliver its final report in 2021. A positive outcome for the petitioners would be groundbreaking. Unlike lawsuits seeking compensation for damages, the national inquiry is focused on preventing further harm and could result in recommendations to policymakers and legislators concerning corporate responsibility for the climate crisis.

KlimaSeniorinnen v. Government of Switzerland:
The KlimaSeniorinnen (“Senior Women for Climate Protection”), supported by Greenpeace Switzerland, and representing more than 1000 women aged 64 and over, sent a formal legal complaint to the Swiss Government and three administrative bodies responsible for national climate policies. The elders are challenging the government’s climate policies, highlighting shortfalls that are putting their lives and future generations at risk. The authorities refused to rule on the request, so they filed their case before the Federal Administrative Court. That court dismissed the case in December 2018 on the grounds that senior women were not more likely than other citizens to experience harmful effects of climate change – despite their increased incidence of death during heat waves. The senior women appealed the case to the Swiss Federal Supreme Court at the end of January 2019. In addition to their case, they are now lobbying for human-rights-compliant 2030 and 2050 targets.

In November 2019, the senior women filed an application at the European Court of Human Rights, with the support of the GPI Legal Unit. This case is globally significant because it is part of the first wave of climate cases in front of the European Court of Human Rights.

Greenpeace France, Oxfam France, Notre Affaire à Tous & Foundation pour la Nature et l’Homme v Government of France:
In 2018, Greenpeace France, in collaboration with Notre Affaire à Tous, Oxfam France, and Fondation pour la Nature et l’Homme, filed a demande préalable (letter before action) as the first step in France’s first-ever climate lawsuit. Dubbed “L’Affaire du Siècle” (the trial of the century), the lawsuit claims that the French government’s inadequate steps to address the climate crisis and its failure to implement international, European, and national climate objectives breaches national and international law, including people’s human rights. Similar to the Swiss case, this lawsuit aims to align France’s climate laws and policies with the Paris Agreement, at a minimum. Within ten days of the letter, the groups’ appeal received more than 1.7 million signatures, demonstrating widespread public support for the case. Since the authorities refused to act as requested by the letter, the co-plaintiffs filed a case in the Administrative Court of Paris on 14 March 2019. On 16 March 2019, the day after the global school strike for climate protection, which mobilised more than 1.6 million young people around the world, 350,000 people marched in more than 200 cities in France in support of the case and to demand increased climate action from the government.

The lawsuit challenges the state’s inaction on climate change and failure to meet its own goals for reducing greenhouse gas emissions, increasing renewable energy, and limiting energy consumption. On 20 May 2019, the 4 NGOs filed their additional pleading in front of the Administrative Court. On 3 February 2021, in a landmark decision, the Paris Administrative Court held the French state liable for its failure to meet its own greenhouse gas emissions reduction targets. It is the first time the State’s responsibility in the climate crisis, because of its lack of action, is acknowledged by French justice.

It’s a victory of truth over the denial of the French state, who has relentlessly claimed its actions are sufficient, despite overwhelming evidence that it is failing. The recognition of the State’s fault and responsibility is a crucial step to obtain a follow-up court order forcing the State to act and a victory for communities asserting their rights everywhere in the world.

Greenpeace México, A.C. v. Ministry of Energy (and others):
This case began in late spring 2020 and received positive results in early November 2020. The Mexican Center for Environmental Law (CEMDA) and Greenpeace Mexico have successfully challenged new federal decrees that limited the participation of renewable energy companies in the domestic market. It is a major victory against anti-renewable measures and helps secure the human right to affordable and accessible clean energy. Community-based renewable projects can help to combat the energy poverty that afflicts millions of households. In addition to the successful proceeding against a local energy secretariat Sener and electricity system operator Cenace obtaining a temporary suspension of parts of the energy policy, Greenpeace Mexico has initiated three additional injunction proceedings demanding the non-compliance of the intermediate targets of the NDC regarding the percentage of clean energies in the country’s power mix. 

Greenpeace East Asia et al v Taiwan Ministry of Economic Affairs:
On 3 February 2021, four individual plaintiffs who live in the areas that are directly impacted by the simulated sea-level rise and storm surge, as well as Greenpeace East Asia and Environmental Jurists Association, filed a lawsuit against Taiwan’s Ministry of Economic Affairs (MOEA). The plaintiffs submit that the MOEA failed to exercise proper administrative discretion when it enacted the “Regulations Governing the Chartered Capacity on Electricity Consumption Agreements Which the Users Shall Install Renewable Energy Facilities for Exceeding a Certain Capacity” (Regulation for Large Power Consumers), in force since January 1st, 2021. Specifically, the plaintiffs argue that the Regulation for Large Power Consumers does not comply with its enabling law, the Renewable Energy Development Act, and that its clauses are insufficient to fulfill the 2025 renewable energy goals under the Renewable Energy Development Act. Therefore, the plaintiffs request the Taipei Administrative Court to order the MOEA and its Energy Bureau to amend the “Regulation for Large Power Consumers” in accordance with the Renewable Energy Development Act and the 2025 renewable energy goal. The filing of this case is a first in Taiwan and a breakthrough in citizen suits and climate litigation. The lawsuit is the first example of ordinary people in Taiwan using the power of strategic litigation to hold the government accountable for its climate inaction.

Right to Protest

Greenpeace engages in confrontational, non-violent direct action to expose environmental crimes. These actions can sometimes lead to legal action against Greenpeace organisations and activists – volunteers committed to environmental protection. Courts across the world have recognised the legitimacy of Greenpeace actions and the right to engage in peaceful protest in democratic societies.

In the District Court of New South Wales, Australia, Judge Lantham exercised her discretion not to impose punishment in sentencing a case for trespass against 29 Greenpeace activists, who had graphically exposed the woeful security at a nuclear plant by penetrating it. Her Honour stated in her decision of 15 May 2002, that: “…The right to protest and the right to express publicly one’s political views, albeit by direct action, is one which is to be valued and protected in the context of modern democracy…”

In 2008, six Greenpeace UK activists were charged with criminal damage following an attempt to shut down the Kingsnorth coal-fired power station in Kent – by scaling the chimney and painting the Prime Minister’s name down the side. The jury returned a ‘not guilty’ verdict, accepting the activists’ defence that they were acting in order to defend property of a greater value from climate change, including everything from the polar ice caps to the tropical rainforests of the Amazon and the Congo basin. In 2009, plans to build a second coal-fired station at the site were shelved.

After activists briefly shut down 72 of Shell’s fuel stations in the Netherlands in 2012, in protest at the company’s plans to drill for oil in Arctic waters, Shell sought a court order banning any further actions on or near its premises. The Amsterdam District Court found that the action had met requirements of subsidiarity and proportionality, and rejected Shell’s demand. In doing so, it held that “The basic principle is that organisations such as Greenpeace are in principle free to take action and to make their views publicly known. The sole fact that such action causes inconvenience to the company targeted by the action – in this case, Shell – does not mean that such action is wrongful.”

The most high-profile recent legal dispute involving a Greenpeace action arose in September 2013, when Russian forces detained the Arctic Sunrise and its crew of 30 and charged them with piracy, in response to a peaceful protest against oil drilling on the continental shelf in the Arctic. The Netherlands – flag State of the vessel – began arbitration proceedings against the Russian Federation, relying on a file of evidence supplied by Greenpeace International. In August 2015, the arbitral tribunal ruled in favour of the Netherlands. Its ruling clearly established the principle that there is a right to protest at sea.  A settlement was eventually agreed between the Dutch and Russian governments. Meanwhile, the ‘Arctic 30’ also filed applications with the European Court of Human Rights, asserting that their right to liberty and to freedom of expression had been violated.

Recently, the Timaru District Court convicted but discharged four activists who had delayed a ship as part of an ultimately successful campaign against oil and gas company OMV’s hunt for fossil fuels in New Zealand. The judge told the activists that “in time, you may be referred to, or remembered, not as offenders, but as leaders in the same way as many advocates for women’s education and women’s suffrage were, in their time, seen as offenders and troublemakers, but are now seen as right-thinking leaders for change.

Freedom of Expression

Greenpeace regularly champions the right to free speech in its defence of the environment. On occasion, when our campaigning hits its target, companies will seek to prosecute and unreasonably restrict what we say or do.

For example, in 2002 the French nuclear fuel company Areva filed proceedings against Greenpeace France, alleging breach of its trademark in relation to the Greenpeace parody of the Areva logo that depicted the risks of the nuclear industry. In 2008, Cour de Cassation, France’s highest court, held in favour of Greenpeace France in declaring that the logo parody fell within the legitimate right of freedom of expression.

The European Court of Human Rights has repeatedly recognised the position of NGOs in society as a ‘critical watchdog,’ by disseminating information and ideas on matters of general public interest such as health and the environment. In Steel & Morris v UK (2005) the Court held that, given this role, NGOs can invoke the same high level of protection as the press under the right to freedom of expression provided they “act in good faith in order to provide accurate and reliable information in accordance with the ethics of journalism…” Greenpeace lawyers play an important role in ensuring publications live up to this requirement and in defending the concomitant right to criticise.

Greenpeace knows all too well that threats to freedom of expression don’t just come from governments. Greenpeace organisations around the world have been targeted in recent years by Strategic Lawsuits Against Public Participation (SLAPPs) – lawsuits designed not to win on their merits but to use the litigation process to drain resources and intimidate critics into silence. Two prominent examples of these corporate attacks on Greenpeace, filed using an anti-racketeering law in the USA, led to the formation of the Protect the Protest anti-SLAPP coalition in 2018. In April 2020, one of these corporate plaintiffs – the logging giant Resolute Forest Products – was ordered to pay almost $1million to the Greenpeace defendants targeted in these attacks, in one of the highest monetary figures ever awarded under California’s anti-SLAPP statute. 

A similar coalition – On Ne Se Taira Pas (We Will Not Be Silenced) – was launched in France earlier the same year with the support of Greenpeace France. The Greenpeace International legal unit is now working with advocacy groups from across Europe to build the resilience of activists and other public watchdogs to SLAPPs and legal intimidation in Europe.

International Environmental Law

Greenpeace is actively involved in lobbying for effective international environmental law to address global problems and has achieved significant successes, such as the involvement in the adoption of the UN General Assembly resolution imposing a moratorium on large-scale drift nets on the high seas and the Biosafety Protocol to the Convention on Biological Diversity, which controls the international trade in genetically modified organisms. Greenpeace also holds formal observer status at many international meetings where the fate of the planet is decided: the Convention on the International Trade in Endangered Species of Wild Fauna and Flora, the Commission for the Conservation of Antarctic Marine Living Resources, the International Whaling Commission, the United Nations Framework Convention on Climate Change and the Food and Agriculture Organisation of the United Nations, among others.

Key Cases

Most of Greenpeace’s campaigns are either about creating or upholding laws. At many moments in our history, cases brought by us or against us have formed movements, secured campaign wins and defended democratic space. We have challenged governments and corporations and have helped shape the law to protect the Planet. Below is a tiny selection.
