The Start and Spread of Extinction Rebellion: A Movement for Climate Justice
Exploring how Extinction Rebellion ignited a global movement demanding urgent climate and ecological action.
The Birth of Extinction Rebellion: Origins and Early Days
In late 2018, a small group of UK activists ignited a spark that would soon blaze into a global movement: Extinction Rebellion (XR). Founded by individuals including Gail Bradbrook, Simon Bramwell, Roger Hallam, and others, XR emerged in response to a growing sense of urgency over unchecked carbon emissions, rapid biodiversity loss, and deepening ecological crisis. Drawing inspiration from successful nonviolent uprisings throughout history, such as the suffragettes and the American civil rights movement, XR pledged to use nonviolent civil disobedience—deliberate but peaceful lawbreaking—to demand a radical change in climate and ecological policies.
The initial months saw high-profile acts, from occupying the London Greenpeace offices to organizing mass blockades of major bridges across the River Thames. By October 31, 2018, hundreds gathered outside the UK Parliament for XR’s “Declaration of Rebellion,” backed by a call to action signed by an unprecedented number of academics and public figures.
Core Demands and Principles
- Tell the Truth: Governments and institutions must openly acknowledge the climate and ecological emergency, accurately communicating the severity and urgency of the crisis.
- Act Now: Immediate action is required to halt biodiversity loss and reach net-zero greenhouse gas emissions by 2025, a target initially believed achievable if governments mobilized rapidly and decisively.
- Decide Together / Beyond Politics: National governments must replace top-down policy with participatory decision-making. XR calls for the creation of citizens’ assemblies—deliberative forums where everyday people, not just elected officials, shape policy responses to the climate and ecological crisis.
In the United States and other countries, XR’s demands have further evolved to highlight social and racial justice, recognize indigenous sovereignty, and demand reparations for environmental harms disproportionately suffered by marginalized communities.
The Philosophy of Nonviolent Direct Action
At XR’s heart lies a strategic commitment to nonviolent direct action. The founders argue that traditional tools—petitions, lobbying, peaceful protest—have consistently failed against entrenched economic and political interests. Therefore, XR deploys disruptive, yet peaceful, tactics designed to make business-as-usual impossible until key demands are met.
- Occupations and Blockades: Shutting down major roadways, bridges, and public squares to draw attention to the crisis and force government engagement.
- Mass Arrests: Many XR activists embrace the risk of arrest and imprisonment, echoing historical precedent that such sacrifices can draw public sympathy and accelerate progress.
- Media Stunts: Striking visuals, such as the circled hourglass extinction symbol and large-scale street art, keep XR in the media spotlight.
Why Civil Disobedience? The Case for Disruption
XR’s approach is rooted in evidence from social sciences: peaceful, large-scale disruption has historically been necessary when those in power fail to act. Gandhi’s Salt March, Martin Luther King Jr.’s marches, and the suffragettes’ protests changed laws not merely through persuasion, but also by disrupting the status quo.
According to XR’s philosophy, disruption provokes public debate and pressures governments to acknowledge ignored problems. The scale of participation also matters: research suggests that sustained, nonviolent campaigns involving at least 3.5% of the population are often sufficient to force significant political change.
The Climate and Ecological Emergency: The Scientific Rationale
What others are reading
The formation of XR coincided with mounting scientific warnings. Reports from the Intergovernmental Panel on Climate Change (IPCC) and leading climate scientists made it clear: Earth was rapidly approaching dangerous tipping points. Biodiversity was in free fall; intense heatwaves, wildfires, floods, and droughts were increasing in both frequency and severity.
By January 2025, for the first time, global average temperatures exceeded 1.5°C above pre-industrial levels, a threshold many scientists call a critical danger line. Billionaires and the world’s wealthiest had already “burned through” the world’s annual carbon budget in under two weeks—a stark illustration of global inequality and inaction.
Every additional tenth of a degree of warming now exposes at least 100 million more people to potentially unlivable conditions. The stakes are existential: failure to act is a “death sentence for millions,” as XR activists often state.
Expanding Across Borders: XR’s Global Spread
XR’s momentum quickly leaped from the UK to dozens of countries. By 2025, more than 88 countries, nearly 1,000 XR groups, and hundreds of local chapters had sprung up around the globe.
XR’s framework is intentionally decentralized—any group can ascribe to its principles and organize under its banner, allowing rapid and flexible scaling. Major events, from city-wide shutdowns in London and Berlin to street art in Buenos Aires and die-ins in Australian malls, have brought millions into the climate conversation.
- International Focus: XR has tailored local actions to highlight specific national or regional failings, such as indigenous land rights in North America or anti-deforestation campaigns in the Amazon.
- Inclusivity: The movement explicitly welcomes people of all backgrounds, aiming for a broad, non-partisan coalition dedicated to planetary survival.
Public Response and Controversies
XR’s bold tactics have sparked heated debate. Surveys reveal a divided public: in a 2019 UK poll, 54% expressed opposition to XR’s disruptive city protests, while about 36% voiced support.
Critics argue that XR’s blockades inconvenience ordinary people and risk alienating the broader public. Others claim the movement does not go far enough to address broader systems of injustice or make climate activism accessible beyond affluent, urban populations.
Despite the criticisms, XR has shifted the conversation: their direct actions have forced governments, media outlets, and even rival environmental organizations to acknowledge the scale and urgency of the crisis. Even those opposed to XR’s methods concede that the group’s visibility has kept climate and extinction on the political agenda.
Key Achievements and Notable Actions
- Mass Arrests: During the 2019 “International Rebellion,” XR actions led to thousands of arrests in the UK and globally, making headlines and testing legal limits on protest.
- Parliamentary Debate: In response to XR and allied movements, the UK Parliament was among the first in the world to declare a “climate emergency,” acknowledging the need for greater action.
- Global Days of Action: XR’s international calendar has featured coordinated worldwide actions across six continents, including unprecedented cross-movement alliances.
- Iconic Symbols: The hourglass extinction symbol, now ubiquitous at protests and online, serves as a stark reminder that the clock is ticking.
The Role of Science and Urgency
“The science is clear. Our future is not.”—a rallying call repeated at every XR event. Climate scientists and biodiversity experts now widely agree: Earth is in a period of cascading crises—melting glaciers, loss of crop yields, oceanic disruptions—that threaten civilization as we know it. XR insists that the only ethical response is to publicly acknowledge this existential threat and act on it like the emergency it is.
XR’s Approach to Political Change
Unlike some earlier social movements, XR does not directly align itself with any political party or ideology. Its focus is on building a new political culture of public participation—a climate citizens’ assembly guided by fairness and transparency. XR argues that a crisis of this magnitude cannot be resolved solely within existing institutions, which have failed repeatedly to confront the climate emergency.
| Traditional Tactics | XR’s Approach |
|---|---|
| Petitions and lobbying | Nonviolent mass disruption |
| Voting for green parties | Visible, decentralized climate action |
| Charity/NGO campaigns | Civil disobedience and public assemblies |
Just Transition and Climate Justice
Many XR chapters have expanded their vision far beyond carbon emissions. In the U.S. and elsewhere, the movement calls for a just transition: one that foregrounds frontline communities, indigenous rights, and economic justice. This means compensating those most affected by pollution and climate chaos, and ensuring that workers and communities are not left behind in the shift to green economies.
- Reparations and Remediation: Addressing years of environmental injustice and repairing the ecological damage is essential to XR’s goals.
- Legal Rights for Nature: XR advocates recognizing the legal rights of ecosystems to thrive and regenerate—an idea gaining ground worldwide.
Challenges, Criticisms, and Lessons Learned
No social movement is without its internal debates and external criticism. XR has faced challenges around inclusivity, accessibility, and the balance between disruption and public support. While some accuse XR of “alienating” potential allies through disruptive tactics, others maintain that urgent crises require uncomfortable, bold action. High-profile property damage and media stunts have sometimes drawn criticism, but XR emphasizes their efforts to avoid endangering people and to keep all actions nonviolent and principled.
The Road Ahead: 2025 and Beyond
It is now 2025, the year when XR originally called for net-zero greenhouse gas emissions. The world did not meet this ambitious goal; global temperatures have crossed critical thresholds, and current trajectories threaten much worse. However, XR’s message remains as urgent as ever. Every fraction of a degree of warming now represents hundreds of millions of lives affected, so activists argue there is no justification for giving up.
XR continues to evolve: building alliances with local and global groups, refining tactics, and insisting that system change—not just individual change—is necessary. The movement’s clarity and audacity have played a key role in keeping climate justice at the forefront of the world’s political agenda.
