Fridays for Future (2018–)

Summary

Fridays for Future (FFF), also known as the School Strike for Climate, is an international movement of school students who skip Friday classes to demand that political leaders take action to prevent climate change and transition the fossil-fuel industry to renewable energy [source: nv-database]. Publicity and widespread organising began after Swedish pupil Greta Thunberg staged a solo protest in August 2018 outside the Swedish parliament, the Riksdag, holding a sign reading “Skolstrejk för klimatet” (“School strike for the climate”) [source: nv-database]. By 2019, the movement had organised more than a million strikers in 2,200 events across 125 countries on a single day (15 March 2019) and four million strikers worldwide during the September 2019 Global Week for Future [source: nv-database].

Tactics used

  • student strike / school walk-out
  • mass street demonstration with transnational coordination
  • media-facing leaderless local-chapter structure
  • open letters and researcher endorsements
  • explicit demands for voting-age lowering to 16 in some countries

Background

Earlier school climate strikes predate Thunberg’s 2018 action: the Australian Youth Climate Coalition formed in November 2006, and 50,000 people in over 100 countries participated in a climate strike on 30 November 2015 timed to the opening of COP21 in Paris [source: nv-database]. Thunberg began her strike on 20 August 2018, in ninth grade, after the 2018 European heat wave and the 2018 Swedish wildfires, saying she was inspired by the Parkland March for Our Lives organisers [source: nv-database]. On 7 September 2018, just before Sweden’s general election, she announced she would continue striking every Friday until Sweden aligns with the Paris Agreement; the slogan “Fridays for Future” took hold, and school strikes spread worldwide [source: nv-database].

What happened

After Thunberg’s solo August 2018 protest, the first multi-person strike took place in The Hague in September 2018, led by Sandor van Gessel, Anne-Laure Stroek, Ianthe Minnaert and Ellis van der Borgh outside the Dutch parliament [source: nv-database]. Strikes spread through Australia, where students publicly defied Prime Minister Scott Morrison’s call for “more learning in schools and less activism”, and through 270-plus cities during the December 2018 COP24 week in Katowice [source: nv-database]. By February 2019, more than 155 local German groups had been counted, organising through WhatsApp, and more than 134 US groups coordinated via Slack with help from Sunrise Movement, 350.org, OneMillionOfUs, Earth Uprising, Future Coalition, Earth Guardians, Zero Hour, and Extinction Rebellion [source: nv-database].

The 15 March 2019 global climate strike drew more than one million people in roughly 2,200 events across 125 countries; on that day Thunberg, Anna Taylor, Luisa Neubauer, Kyra Gantois, Anuna De Wever, Adélaïde Charlier, Holly Gillibrand and Alexandria Villaseñor co-authored a Guardian guest editorial restating the strikers’ demands [source: nv-database]. In Germany alone, more than 300,000 students demonstrated in 230 cities, including more than 25,000 in Berlin [source: nv-database]. The 24 May 2019 strike, timed to the second day of the 2019 European Parliament election, drew hundreds of thousands across 1,600-plus towns in 125 countries; polling identified climate change as the most important issue for German voters in that election [source: nv-database]. The Aachen strike on 21 June 2019 drew roughly 40,000 protesters, making it the largest single FFF demonstration in a German city up to that point; speakers included Cyril Dion and activists from Ende Gelände and the Hambach Forest [source: nv-database].

The September 2019 Global Week for Future — built around 20 and 27 September and the 23 September UN Climate Action Summit — drew an estimated four million strikers on 20 September (1.4 million in Germany alone) and roughly two million on 27 September (over one million in Italy) [source: nv-database]. The 29 November 2019 strike, timed to the start of COP25 in Madrid, took place in 2,400 cities across 157 countries with an estimated two million participants [source: nv-database]. Subsequent global actions took place on 25 September 2020, 19 March 2021 (reduced by COVID-19 restrictions), 24 September 2021 (where Thunberg addressed 100,000 in Berlin declaring “No political party is doing enough”), 25 March 2022, 23 September 2022 (more than 30,000 in Berlin), and 3 March 2023 (more than 220,000 across Germany) [source: nv-database]. On 15 June 2021 the Auckland chapter of New Zealand’s School Strike 4 Climate formally disbanded on the grounds that it had been racist towards BIPOC members; the Wellington coordinator of 350 Pacific Climate Warriors and national coordinator Sophie Hanford rejected that framing and called for indigenous leadership on climate justice [source: nv-database].

Key people & organizations

  • Greta Thunberg (founder, Sweden)
  • Sandor van Gessel, Anne-Laure Stroek, Ianthe Minnaert, Ellis van der Borgh (first multi-person strike, The Hague, September 2018)
  • Luisa Neubauer (Germany)
  • Anna Taylor (UK)
  • Anuna De Wever, Kyra Gantois, Adélaïde Charlier (Belgium)
  • Alexandria Villaseñor (US)
  • Sophie Hanford (New Zealand national coordinator)
  • Parents for Future (support initiative, Germany 2019)
  • Sunrise Movement, 350.org, OneMillionOfUs, Earth Uprising, Future Coalition, Earth Guardians, Zero Hour, Extinction Rebellion (US coordinating allies, 2019)

Outcome

Verdict: partial.

The movement succeeded as a transnational mobilisation: by September 2019 it could credibly claim four million strikers worldwide on a single day, a level of cross-border youth coordination without historical precedent [source: nv-database]. In specific policy terms it is judged partial because the strikers’ principal demand — alignment of national policy with the Paris Agreement — has been unevenly met; in 2019 EU Commission President Jean-Claude Juncker announced an intent to spend hundreds of billions of euros on climate mitigation (roughly a fourth of the EU budget) in a speech alongside Thunberg, and media credited the strike movement with provoking the announcement [source: nv-database]. By the early 2020s the Auckland chapter had dissolved and European chapters were facing internal scrutiny over race and inclusion, complicating the “won” verdict.

Lessons

  • A solo, highly visible, low-cost weekly action by a teenage actor can produce a transnational movement in roughly twelve months when paired with sustained media coverage.
  • Explicit alignment of demands with an existing international agreement (the Paris Agreement) gives national chapters a concrete, defensible policy target that travels across jurisdictions.
  • Decoupling local organising (Slack in the US, WhatsApp in Germany, ad hoc in many countries) from a thin coordinating layer allows rapid scaling without centralised bottlenecks.
  • Researchers and scientists can be mobilised as endorsers and speakers (UK 224 academics in February 2019; German-speaking researchers 26,800 signatories) to broaden the movement’s legitimacy without diluting its youth-led identity.
