| Source | Coverage | Evidence used in this article | Finding supported |
|---|---|---|---|
| Wahlstrom et al. (2019); de Moor et al. (2020) | Global climate strikes, 2019 | 1.6 million participants in March 2019; about 7.6 million participants across about 6,000 events in 185 countries in September 2019 | Establishes the 2019 protest crest as an exceptional baseline rather than a normal benchmark |
| Carnegie Climate Protest Tracker and Goh & Gordon (2025) | Climate policy protests tracked since 2022 | Reports one million participants in the September 2023 Global Climate Strike; tracked climate protests increased every year since 2022; anti-climate protests in 2024 more than doubled those in 2023; 2019 treated as the movement peak. | Supports the claim that activism persists after the 2019 peak but is more fragmented, contested, and unevenly visible. |
| ACLED methodology and Pavlik (2019) | Cross-regional protest event coding | ACLED codes demonstrations as physical congregations of three or more people directed at a policy, institution, group, or issue; Fridays for Future events were mapped across several regions from September 2019 | Supports the event-based reading of diffusion beyond a single Western protest cycle |
| UNECE Special Rapporteur (2024) | Europe-wide institutional assessment | Documents a snapshot of the repression and criminalization of peaceful environmental protest and civil disobedience | Supports the deterrence and chilling-effects argument |
| Reuters (2024, 2025) | United Kingdom turning-point events | Five Stop Oil activists received the longest sentences imposed for non-violent protest in Britain in July 2024; Just Stop Oil announced the end of its direct-action campaign in March 2025 | Supports claims about legal escalation, participation costs, and tactical retrenchment |
| Movement | Emergence | Signature repertoire | Observed weakening or transformation |
|---|---|---|---|
| Fridays for Future | 2018, catalyzed by Greta Thunberg’s school strike | School strike, transnational youth marches, moral framing around future generations | Mass synchronization after 2019 weakened, although strike activity and local chapters continued. |
| Extinction Rebellion | 2018 in the United Kingdom, diffused internationally by 2019 | Civil disobedience, disruption, arrestable protest, citizens’ assemblies | Strategic shifts, participant churn, and heightened repression altered the movement’s composition and public image. |
| Just Stop Oil | 2022 in the United Kingdom | High-visibility disruptive direct action targeting roads, culture, and symbolic sites | Ended its direct-action campaign in 2025 after three years of disruption, imprisonment, and strategic reassessment. |
| Last Generation | Early 2020s in continental Europe | Road blockades, adhesive disruption, airport and transport interventions | High visibility was accompanied by strong backlash and punitive legal responses, narrowing participation. |
| Sunrise Movement | Late 2010s in the United States | Institutional campaigning, youth mobilization, Green New Deal advocacy | Became more embedded in formal politics but less singularly visible on the global protest stage. |
