Ella Ward sat in jail in the UK for 10 months, waiting to be sentenced for planning to disrupt Manchester Airport in August 2024. When the sentence was handed down this May, it was 18 months in prison for Ward, with other protesters receiving up to 30 months.

Ward and their fellow activists from climate change direct action group Just Stop Oil never reached the runway, where they intended to glue themselves as part of a co-ordinated European action. Instead, according to an account from Ward, police arrested the activists on a side street in Manchester just after 4am on 5 August for planning the protest, which would have caused “severe delays”.

Four JSO activists were charged with conspiracy to cause a public nuisance and found guilty in February.

Ward, 22, a former environmental science student at the University of Leeds, is a serial activist. They have slow-marched down roads for JSO (for which they spent time in prison before charges were dropped) and thrown paint over think tank Policy Exchange, and they were one of three young people – under the banner of Youth Demand (an offshoot of JSO) – who left children’s shoes outside the home of Keir Starmer, then leader of the opposition, to protest against the killings in Gaza.

None of these actions have been violent, although many have caused offence and disruption. But the fact that Ward and others have been sentenced to prison for months demonstrates how the UK has been clamping down on protest when it would once have dealt with such direct actions with fines.
JSO, whose activists threw soup over Vincent Van Gogh’s Sunflowers at the National Gallery, announced earlier this year that it was stopping its activities.

The official reason given was that its demands – for no new oil and gas licences to be issued – had been met. But at the group’s final demonstration through London in April, it was clear that the imprisonment of key activists was a major concern: there were as many protesters holding up pictures of activists who had been jailed as there were messages about climate change and the fossil fuel industry.

Ths shift in protest policing

Mel Carrington, 63, is a JSO spokesperson who was acquitted in June after blocking the departure gates at Gatwick Airport with suitcases last year. She told Index: “We have to respond to repression, and all our most radical people are in prison. So it does have an impact.”

There are currently 11 JSO protesters behind bars. Co-founder Roger Hallam (also co-founder of Extinction Rebellion, or XR) is serving a four-year sentence (reduced from five years) for conspiracy to cause a public nuisance. His crime was playing a major role in a Zoom meeting where he was found to have conspired in a “sophisticated plan” for activists to climb gantries over the M25 – a motorway which circles London – and disrupt traffic. Hallam did not participate in the action, which took place in November 2022, but the law enabled him to be imprisoned for the protest nonetheless.

Locking up climate protesters is relatively new in the UK. Richard Ecclestone, an XR spokesperson and a former police inspector, said the attitude of the police, as well as actual laws, had changed dramatically over the last six years, which he found “very disturbing”. Police used to facilitate protest, now they are shutting it down.

“We don’t want to be like Russia, China or North Korea. That’s not who we are,” he told Index.

Recent anti-protest legislation has given police the power to stop almost any action they don’t like and granted the courts expanded powers to imprison protesters, although the Court of Appeal decided in May that the idea of “disruption” – which led to Swedish climate protester Greta Thunberg being arrested in London – had been drawn too widely and that “serious disruption” could not be categorised as anything “more than minor”.

The 2022 Police, Crime, Sentencing and Courts Act has proved particularly effective at shutting down civil disobedience, while protest-related offences under the Public Order Act 2023 were introduced in direct response to environmental activism. Serious Disruption Prevention Orders introduced in 2024 also mean the courts can prevent people from taking part in disruptive protests after they’ve been convicted of protest-related offences, and breaching the order would be a criminal offence.

Mothers supporting daughters

The Labour government, elected last year, is seeking to give police even more powers to control demonstrations. Amnesty International has highlighted provisions in the new Crime and Policing Bill currently going through parliament which seek to ban face masks and criminalise climbing on war memorials.

The courts have also blocked the right for defendants to use beliefs and motivation as a lawful excuse for causing a nuisance, damage or disruption in most cases.

Ward’s mother (who didn’t want her name to be published) was on the march, as was Rebecca, the mother of Ruby Hamill, another protester who, at the age of 19, was held in prison for slow-marching. Ruby has now been released. Both mothers went on the final JSO march in support of their daughters.

Ward’s mother told Index: “My daughter is very passionate and compassionate and feels deeply about the injustice of the climate crisis and how it’s affecting the global south, and wants to let people know as much as possible. She’s done the most she possibly can do by putting her liberty on the line. She knew the potential outcome.

“She told the jury in the trial she would be at peace with whether she is found guilty or not guilty … the point of her action is to get the message out there. I’m here in solidarity with my daughter and all the other people who have been imprisoned.

“It’s a very conflicting place for a parent – so worried about them being in prison but conversely proud of them for standing up for their beliefs.”

The UK’s deteriorating record

The UK has a poor record when it comes to arresting climate protesters who, like JSO members, have been non-violent and allow themselves to be arrested.

A recent report from the University of Bristol, called the Criminalisation and Repression of Climate and Environmental Protests, looked at government responses across a range of countries.

The report found that 17% of climate and environmental protests in the UK involved arrest, making it the second most likely country (after Australia at 20%) to take environmental protesters into police custody.

It is not the only country to have clamped down heavily on climate protest. France has reached for anti-terror laws, and Spain, Germany and the USA have used legislation designed to tackle organised crime.

Separately, climate activists in the UK have often been subject to civil proceedings such as injunctions which prevent named (and sometimes unnamed) individuals from going near certain places. Carrington says these injunctions can be as intimidating as criminalisation, making people afraid they could lose their savings or their jobs.

In 2022, JSO protester Louise Lancaster was ordered to pay £22,000 for breaching an injunction preventing her going on the M25.

Carrington herself found that she couldn’t renew her house insurance because of proceedings against her. She also claimed teachers had discovered their jobs were at risk because criminal prosecutions for climate change action turned up in Disclosure and Barring Service (DBS) checks.

Another way forward?

All of this risks environmental protesters going underground and carrying out actions with less accountability. There are already organisations such as The Tyre Extinguishers whose members deliberately let down the tyres of SUVs and then scarper, or Shut The System, which sabotages infrastructure.

But the authors of the Bristol report recommended another way forward.

“Governments, legislatures, courts and police forces should operate with a general presumption against criminalising climate and environmental protests,” it said. “Instead, climate and environmental protest should be regarded as a reasonable response to the urgent and existential nature of the climate crisis, and activists engaged as stakeholders in a process of just transition.”

The leaders of climate change movements agree and are working out how to pivot to a less disruptive street-based approach and one which might garner more public support. Ecclestone says XR was interested in using citizens’ assemblies to achieve change and that a lot of work was going on to see how that could be made to work.

Carrington said JSO had a project as part of the umbrella group Assemble which aimed to build on the idea that politics was broken and corrupt, and that building a political project from the grassroots up was the way to achieve change.

She said: “What we need to do more than ever is to come together and to work together to survive the storm that’s coming.”
