UK climate activist group Pipe Busters first broke into the construction site for the Southampton to London Pipeline (SLP) in June. Using an array of carefully selected tools, from bolt cutters to a circular saw, they damaged several sections of uninstalled pipeline and a construction vehicle.

This wasn’t a random act: the pipeline’s main function is to supply Heathrow with aviation fuel.

“Aviation is a planet killer,” said Pipe Busters in an emailed statement. “Pipe Busters act to halt the expansion of flying that the SLP would make possible.”

In a year in which heat records were smashed across the globe, a new wave of climate activists seems to have simultaneously begun its own campaign of breaking things. During the summer, Just Stop Oil activists destroyed several petrol pumps on the M25, while This Is Not a Drill smeared black paint on buildings and smashed the windows of organisations linked to fossil fuels.

The disruption has continued into the autumn. Last week, Just Stop Oil threw black paint on Altcourse prison in Liverpool, in protest at one of their number being held in custody. On Monday, This Is Not a Drill’s website reported that campaigners had broken the front windows of the Schlumberger Cambridge Research Centre at Cambridge University, to draw attention to the recent disastrous flooding in Pakistan.

Outside the UK, the French arm of Extinction Rebellion made the news for filling golf course holes with cement. Another group, the Tyre Extinguishers, have started a crusade against SUVs in urban environments across a number of countries by deflating their tyres.

Not that long ago, climate activism made the headlines for school children skipping class to protest, so these more radical tactics seem to mark a turning point.

Losing patience

“I've tried all the conventional main means of creating change – I’ve had meetings with my MP, I’ve signed petitions, I’ve participated in public consultations, I’ve organised and taken part in marches,” says Indigo Rumbelow, a Just Stop Oil activist. “The conventional ways of making change are done.”

Marion Walker, spokesperson for the Tyre Extinguishers, added: “We want to live in towns and cities with clean air and safe streets. Politely asking and protesting for these things has failed.

“The only thing we can do is make it impossible or extremely inconvenient to own [an SUV].”

The need for urgent action on the climate is not in doubt. These campaigners are frustrated by what they see as a lack of meaningful steps taken by governments to stem the flow of carbon into the atmosphere. Despite the need to move away from fossil fuels, for instance, the UK government recently opened up a new licensing round for North Sea oil and gas.

Andreas Malm, associate professor in human ecology at Lund University in Sweden, made the case for sabotage as a legitimate form of climate activism in his provocative 2021 book ‘How to Blow Up a Pipeline’ – and he seems to have inspired others to follow his lead. Deflating SUV tyres, for example, is something Malm writes about and says he has done in the past.

But is breaking stuff – temporarily or otherwise – really an effective form of action for a movement trying to communicate on such a serious issue?

“Coordinated, sustained social movements that do destroy property tend to be pretty effective over the long term,” says Benjamin Sovacool, professor in energy policy at Sussex University.

Sovacool highlights three global movements – the abolition of slavery, the prohibition of alcohol and the civil rights movement – that used violence, including destroying property, to achieve their goals.

“Some work in sociology even suggests that violent social movements are actually more effective than non-violent ones,” he adds.

In his own paper, Sovacool cites research from the late 20th century that looked into US social movements, and found that American activists in the 1980s who were willing to use violence were able to reach their objectives more quickly than those who weren’t. He goes on to describe a number of actions that could fall under the umbrella of violence, from destroying property through to assassinations and bombings.

Others refer to property destruction as “unarmed violence”, and research suggests movements that adopt this specific style of violent tactic are more successful than others. Movements highlighted as having used unarmed violence include the Chuquisaca Revolution in 1809, and the overthrowing of the military dictatorship in Argentina in 1983.

But there isn’t a consensus. Other research looking at similar kinds of movements comes to a different conclusion, indicating that violent tactics are less successful in specific cases, such as those seeking regime change.

For any kind of action to have an impact, though, it has to be noticed.

German climate movement Letzte Generation, part of the international A22 network that includes Just Stop Oil, sabotaged a number of fuel pipelines across Germany this spring – more than 30 times in total, the group claims.

“We asked ourselves, what can we do to really put pressure on the government to give us a reaction towards our demands?” says Lars Werner, who was involved in the action. “We did it publicly – it wasn't an action that we wanted to hide from.”

But despite their enormous logistical efforts, the media coverage was underwhelming. The corporations targeted didn’t react publicly, either. “The government could ignore what we were doing because there wasn’t much attention,” says Werner. Following the action, the group reverted to its old tactics of blocking roads.

Accountability or anonymity?

Indigo Rumbelow is keen to highlight the importance of accountability – showing names and faces – to Just Stop Oil’s activism. Other groups, such as the Tyre Extinguishers, prefer to remain anonymous.

“We’re trying to change the narrative around fossil fuels,” says Rumbelow. “We’re not trying to materially stop fossil fuels – we don’t have enough people, resources or power for that.

“But by having our face attached to the action and being able to explain, ‘I did this and I believe that I am right because it's the only right thing to do’ – that's how we're going to change the political story,” she says.

Choosing to remain anonymous, and not being accountable for your actions, can also be risky.

“If you put a mask on, there’s the danger of labelling those people in masks as terrorists,” says Laurence Delina, assistant professor in environment and sustainability at the Hong Kong University of Science and Technology. He adds that this can be taken advantage of by others, such as fossil fuel interests, to demonise activists and undermine their message.

Indigenous communities

Those on the frontlines of resource extraction, however, don’t have the privilege of being able to decide whether they want to be accountable or not. Many Indigenous communities – such as the Wet’suwet’en, Pacheedaht, Ditidaht, Mapuche and Sioux peoples across the American continent – have used their bodies to obstruct pipelines, as well as logging and mining vehicles, that would otherwise destroy their lands. Some have resorted to arson to protect their way of life.

Not only do these communities have fewer options; retaliation is usually more severe too, sometimes deadly. A Guardian investigation revealed in 2019 that Canadian police had discussed using lethal force against Wet’suwet’en activists blocking the construction of a gas pipeline. Last year, Global Witness reported that 277 land and environmental activists were murdered in 2020 for defending their land and the planet. Most of these incidents occurred in the Global South.

Despite differences in opinion, there is a consensus among Malm, Walker and Rumbelow that sabotage, if used, would be most successful as part of a broader movement – that it is one tool in a wider arsenal, not the answer in itself.

Delina thinks that sabotage is a legitimate tactic, but only in situations where all other avenues of action have been explored, emphasising that he thinks non-violent actions are preferable.

Sovacool doesn’t advocate for sabotage, but agrees that a multiplicity of tactics is useful, and that it’s important for us to be able to talk about how successful sabotage has been in the past. “I think each person has to decide on their own threshold for action,” he says.
