Climate strike

1. 1

   4M+. According to the organizers, more than 4 million took to the streets on 20 September 2019, in 150 countries, 13 months after the first solo strike.

2. 2

   3 people were enough to start a local group. The ritual was fixed: every Friday, same place, same time, a handmade sign.

3. 3

   A gesture anyone could copy, a four-step guide and a clear press rule carried the movement. Press attention alone did not change policy.

If you're new to this, start with the fundamentals, from the vote goal to what the research says. Read the fundamentals

The movement always refused to have a boss. This playbook is built from what the organizers themselves published (the guides for local groups, the structure paper and the press concept of Fridays for Future in Germany, the international movement's guidance pages) and from interviews and books by those at the front. Many organizers were minors: only people who have publicly taken on their role appear here.

• Greta Thunberg

  Initiator of the school strike for climate (Stockholm, 2018)

  Began the strike alone outside the Riksdag, posted the first photo on Instagram and, with other strikers, decided in September 2018 to carry on every Friday and launch #FridaysForFuture.

• Promote new faces and move the very well-known further back in the queue, so that a few faces don't come to represent the whole movement.

  Presse-AG of Fridays for Future Deutschland, Pressekonzept v1.0.1, 25 Mar 2021

At the end of summer 2018, after heatwaves and fires, a 15-year-old student tried to persuade classmates to go on school strike for the climate. Nobody was interested. On 20 August she went alone to the front of the Swedish parliament with a sign. Thirteen months later the same image (young people with handmade signs, on a Friday, outside a building of power) was repeated in thousands of cities.

From one person to millions

1. 20 Aug 2018Greta Thunberg sits alone outside the Riksdag with the sign “Skolstrejk för klimatet” and posts a photo on Instagram. The same day, according to Svenska Dagbladet, entrepreneur Ingmar Rentzhog of the start-up We Don’t Have Time brings a freelance photographer, posts her photo on Facebook and Instagram and an English-language video on YouTube. On the second day others join her; within about a week the international press arrives.
2. 7–8 Sep 2018On the eve of the Swedish election, she and other strikers decide to carry on every Friday until Swedish policy is in line with the Paris Agreement, and launch #FridaysForFuture with an invitation to young people worldwide.
3. Dec 2018Thunberg's speech at COP24 in Katowice goes viral. More than 20,000 students strike in at least 270 cities. On 14 December, Luisa Neubauer is organizer and spokesperson of one of the first strikes in Germany.
4. Jan 2019Vanessa Nakate begins a solitary strike outside Uganda's parliament. In Switzerland and Germany, at least 45,000 students protest on 17 and 18 January.
5. 15 Mar 2019First global strike: about 2,200 events in 125 countries. In Germany alone, more than 300,000 students in 230 cities. Researchers run surveys in 13 European cities.
6. Apr 2019Fridays for Future in Germany publishes the guide to starting local groups and adopts the first version of its structure paper (14 Apr), voted on by the groups.
7. 20–27 Sep 2019Global week for climate: more than 4 million on the 20th (1.4 million in Germany, at 575 demonstrations) and about 2 million on the 27th. For the whole week, the Guardian estimated about 6 million; 350.org, 7.6 million.
8. Jan–Mar 2020In Davos, AP crops Vanessa Nakate out of a photo with four European activists and later apologizes. With the pandemic, strikes move into homes and onto social media.
9. Oct 2023–2025The Gaza war divides the movement: in late October 2023, Thunberg and the international account post messages of solidarity with Palestinians that call the Israeli offensive a genocide; German FFF says those posts do not represent it, and Neubauer says differing views on Israel and Palestine do not justify antisemitism or misinformation. On 14 February 2025, one week before the German election, more than 130,000 people at more than 150 actions, according to the organizers.
10. Oct 2026In Austria, the first national strike since spring is called by a network of about 300 active people in eight states; an August 2026 study describes more delegitimization in the media and more repression since 2022.

Three layers

There was no headquarters and no boss. There were three layers, linked by chats, delegates and a common date.

• The gesture and the common datesThunberg and the international account set the example and announced the global strikes; the website offered the map, the free logo and the guide on how to strike.
• Autonomous local groupsAny town with at least three activists could have its own group, with its own chat, plenary, delegates and press contact. In Germany they coordinated through a national call in which each group had one vote.
• Adult alliesScientists for Future backed up the facts, Parents for Future and NGOs such as Greenpeace and BUND helped with logistics, and 350.org co-organized the September 2019 week. Alliances with trade unions came later.

The method was born in Europe, with a free press, the right to protest and open social networks, and was copied in very different countries. Knowing what depended on that terrain helps you choose what to swap in yours.

Platforms

Instagram

Where the first photo was posted and where local groups announced strikes and shared photos afterwards. A network analysis from February 2019 showed that this was where the people directly involved were.

Twitter (now X)

The stage of journalists, politicians and researchers: it was there that the strike was amplified beyond the bubble and that many press requests began.

WhatsApp and Telegram

The backbone of local groups in Germany: the official guide said to start with a group on either one and send the link to the coordination team to be listed on the website.

Slack and video calls

In the US, organizers coordinated on Slack; in Germany, the national delegates' call and the teams met by phone and video (BigBlueButton, Jitsi).

Local and national press

Newspapers, radio and TV were the main multiplier of the strike's image: students skipping class on a Friday were news in themselves.

Its own tools

The German movement built open tools: a generator of images in the movement's style (Toolpic), a cloud, shared text editors, polls, a link shortener and an email address for each local group.

Local conditions

• Summer 2018 was the hottest ever recorded in Sweden, with forest fires, and a general election was due on 9 September: a deadline and a topic on everyone's mind.
• Most strikers could not vote: skipping class was the only form of pressure within their reach, and the transgression was what made the strike news.
• Big international stages gave peaks of attention: COP24 in Katowice (December 2018), the Davos Forum (January 2019), the UN Climate Summit (September 2019).
• The right to protest was guaranteed in most of Europe, with demonstrations registered in advance with the police or local authority.
• Support from credible adults: thousands of scientists signed letters (Scientists for Future), and Parents for Future and alliances with NGOs emerged.
• Hostility from part of the political class, which called the strikes truancy; in some countries there were punishments and arrests, and in July 2020 India blocked the Indian collective's website.
• The 2020 pandemic took the movement off the streets at its peak and pushed the strikes into online formats.

Fridays for Future did not invent the strike or youth protest. The combination was what was new: a gesture anyone can copy alone, a structure that lets any group copy it under the same name, and press work designed to show many faces instead of one.

Three fronts

The repeatable ritual

Same place, same time, every Friday, outside a building of power, with a handmade sign and a science-based demand. Repetition makes it easy to join; the image is always the same and always photographable.

The open franchise

A free logo for anyone striking (banned for parties and companies), a map to register each action, a four-step guide to starting a local group and global dates when everyone goes out together.

Organized press

One press contact per local group, a national team that stays out of sight and hands out requests, spokespeople chosen by topic, region and diversity, and photos sent to newsrooms on the day.

The cycle of a strike

Each global strike repeated the same eight steps, from a few weeks before to the day after.

1. Set the date One common date for everyone, tied to a political moment: an election, a summit, a vote.
2. Register Each group puts its action on the map and notifies the local authority if the law requires it.
3. Recruit A chain message with the group link, invitations to friends and classmates, posters at school. Direct contact counts for more than social media.
4. Alert the press A media advisory to local newsrooms: time, place, what there will be to photograph, who speaks and who answers the phone.
5. Prepare the speakers Choose spokespeople, give them two or three messages and the numbers, rehearse the hard questions.
6. Strike Signs, chants, short speeches. Photograph during the action and send the best images to newsrooms right away.
7. Count and show Publish the number of people and locations (saying who counted), the photos and the demand. And measure what happens off-screen: how many people came back, how many came for the first time, how many new local groups opened and what concrete response came from decision-makers.
8. Thank people and set the next date Thank everyone who came, review what went wrong at the plenary and announce the next date.

And again.

1. A Friday ritual: same place, same time

   A gesture one person can start tomorrow and anyone else can copy: same place, same time, every week, outside a seat of power, with a hand-made sign and a science-based demand. It began with one student alone in Stockholm on 20 August 2018, but the first amplification was not solitary: the same day, according to Svenska Dagbladet, entrepreneur Ingmar Rentzhog (We Don’t Have Time) brought a photographer and posted her photo and an English-language video.

   How to set it up, step by step

   Works when

   It works when an urgent issue is on everyone's mind and there is a seat of power where the image repeats and is always photographable.

   Don't use when

   It fails if place and time change every week, or where protest is repressed: there, start with small, dispersed, safe actions.

   1. Week −12 Choose the seat of power and a fixed day and time
   2. Week −12 Write your sign in your own voice, with a demand backed by science
   3. Week −12 Notify the police or local authority if the law requires it
   4. Week −11 Send time, place and what there will be to photograph to local newsrooms
   5. Week −10 Come back every week at the same time, even with few people
   6. Week −8 Post photos and the turnout after each strike

   Team

   • Founding striker: holds the place and time every week
   • Photo and social: takes pictures and posts the round-up
   • Press contact: alerts newsrooms and answers the phone

   What to measure: People present each Friday and how many came for the first time, counted on site.

   Risks to watch: Minors in public under scrutiny: parental consent for photos, no full names or schools, and an early conversation with the school about absences.

2. A local group: three people, four steps

   An open franchise: any three people in the same town can open a local group with a chat, two or three elected and recallable delegates and a single press contact, with name and logo free to use. On 20 September 2019, according to organisers, there were actions in some 4,500 places in 150 countries.

   How to set it up, step by step

   Works when

   It works when the gesture is ready to copy and people in other towns want to do the same.

   Don't use when

   It fails if the name and logo serve parties or sales, or when autonomy turns into division with no shared rule for settling disagreements.

   1. Week −8 Publish the four-step guide and the logo free for strikers
   2. Week −8 Gather three people in the same town and open the group on Telegram or WhatsApp
   3. Week −8 Elect two or three delegates and one press contact
   4. Week −7 Send the group link to the local-groups page
   5. Week −6 Set a weekly plenary with rotating chairs and minutes
   6. Week −4 Link delegates to the coordination call, one vote per group

   Team

   • Local core: opens the chat, schedules the plenary and guards independence
   • Delegates: carry decisions both ways, recallable at any time
   • Moderation: prepares the call, writes minutes and publishes results

   What to measure: New local groups opened with a chat, delegates and a press contact in place, counted on the groups page.

   Risks to watch: Young people's data and harassment: use a group email instead of a minor's personal one, collect the minimum and have a contact point for threats.

   Add to my kitIn my kit

3. Press with rules and many faces

   One person per group takes all press requests, a national team that gives no interviews allocates them, and spokespeople are picked by written criteria (topic, region, diversity) in rotation. The German movement put new faces in front and very well-known ones further back.

   How to set it up, step by step

   Works when

   It works when the press is already seeking the movement and a few faces risk coming to stand for everyone.

   Don't use when

   It fails if whoever answers the phone always becomes the speaker, or if someone accepts a big show alone on behalf of the movement.

   1. Week −6 Write the rule: who takes requests, who decides and by what criteria
   2. Week −6 Open the requests sheet: outlet, deadline, who was put forward and why
   3. Week −3 Brief spokespeople with two or three messages, the figures and the hard questions
   4. Week −1 In the week of the action, choose spokespeople by region
   5. Week −1 Check who is in the photos before sending them to newsrooms
   6. D-day week On the day, the press contact is on site with the phone on
   7. 1 week(s) after Afterwards, review each appearance and change the rotation order

   Team

   • Local press contact: receives all of the group's requests
   • National press team: allocates requests and briefs spokespeople, gives no interviews
   • Spokespeople: several people in rotation, picked by criteria
   • Care and awareness: contact point for threats and abuse

   What to measure: Different briefed spokespeople who actually gave interviews in the period, counted in the requests sheet.

   Risks to watch: A single face draws all the hate: rotation, preparation and an activist-defence network ready for threats and smears.

   Add to my kitIn my kit

4. A global date tied to a political moment

   One shared date for everyone, tied to an election, summit or vote, with every action on the map, a media advisory to newsrooms and a round-up the same day. On 15 March 2019, some 1.6 million people took to the streets, according to an estimate cited by researchers, and 38% of the students surveyed were at a protest for the first time.

   How to set it up, step by step

   Works when

   It works when there are enough local groups and a nearby political moment that gives the press a hook.

   Don't use when

   It fails if the number is inflated (then the number becomes the story) or if attention is not turned into concrete asks of decision-makers.

   1. Week −8 Choose the shared date, tied to a vote, summit or election
   2. Week −3 Each group puts its action on the map and notifies the authority if required
   3. Week −3 Start the recruitment chain: group link to friends and classmates, posters at school
   4. Week −2 Send the first media advisory to local newsrooms
   5. Week −1 Send the second advisory with the expected images and confirmed local figures
   6. D-day week On the day, count people, send photos during the action and post the round-up
   7. 1 week(s) after The next day, say thanks, gather the clippings and announce the next date

   Team

   • Coordination: sets the date and keeps the map
   • Recruitment: drives the message chain and the posters
   • Press: advisories, photos and round-up

   What to measure: Places registered on the map and people present (stating who counted), plus the concrete responses from decision-makers.

   Risks to watch: Inflated numbers and unlawful ads destroy credibility: say who counted, and check political-advertising rules before paying for any ad.

From the first strike alone to a strike with the press prepared, as a checklist. Your progress is saved in this browser.

The movement was made up largely of minors, under intense public attention. Fridays for Future's own strike culture already ruled out violence, damage, litter, profit and hate. These rules protect people and credibility.

Protest law

Notify the police or the authority when the law requires it; check the rules on amplified sound and routes. The movement warns that it can rarely offer legal support: find NGOs with protest lawyers beforehand.

Minors and consent

Get guardians' permission for photos and interviews of minors; don't publish full names, school or address; collect as little personal data as possible (GDPR, LGPD).

School

Skipping class can have consequences. Talk to the management and teachers first, bring the scientific information and offer alternatives inside school.

Independence

No link to parties or commercial interests. The logo may not be used by parties or to sell things.

Real people only

No fake profiles, bots or bought accounts to inflate the strike, report opponents or fake support. Coordinating real people to say what they think is allowed; what platforms punish is organizing likes, follows or hashtags to game the algorithm. X, for example, bans trading engagement and using a trending hashtag to manipulate the conversation.

Honest numbers

Say where the count comes from (organizers, police) and don't inflate it. An exaggerated number becomes the story.

Protection against harassment

Have a point of contact for threats and abuse, an identified activist-defence network and a procedure for taking serious threats to the police.

Money in the open

Recorded donations and a public financial report; no sponsorship from companies that profit from fossil fuels.

Using other people's names

Nobody uses an activist's name or image to raise money without her permission, as a Swedish start-up did with Thunberg in 2018, according to the Swedish press.

Local law

Every country has its own rules on protest, minors' data and political advertising. In the EU, Regulation (EU) 2024/900 requires labels and transparency notices on paid political ads, and since October 2025 Meta no longer accepts political, electoral or social-issue ads in the EU (which can include climate ads), and Google has stopped serving political ads. Check with a lawyer before you start.

Attention, but no laws

Millions in the streets and front pages did not, by themselves, deliver the laws demanded. In 2025 Neubauer admitted she had expected catastrophes to change politics, and they didn't; German FFF turned to working with trade unions and alliances.

The peak doesn't last

From more than 4 million in one day in 2019 to 130,000 in Germany in February 2025, according to the organizers; in Austria, in 2026, a network of about 300 active people. As early as September 2019 researchers saw the “Greta effect” fading.

Faces attract hate

Those who appear receive threats, stalking and smear campaigns, including doctored videos. Without rotation and care, the movement burns out the people it exposes most.

The press chooses who it shows

The cropped Davos photo and the end of the Auckland group in 2021, over racism towards people of colour, show that a global movement can reproduce who is already visible.

Autonomy divides

With no centre, there is nobody to settle a disagreement. The Gaza war, from 2023, publicly split the international account and the German group, and cost trust on both sides.

It depends on the street and the calendar

Holidays, exams and the 2020 pandemic broke the rhythm. The online strike kept the ritual, but not the force.

Five questions to confirm the essentials. Each answer comes with an explanation.

This playbook was built mainly from the guides and internal documents that Fridays for Future published (the international website, the guides for local groups and the German movement's wiki, including the Pressekonzept), interviews and books by organizers, the Protest for a Future report and reporting from 2019 to 2026. All pages were consulted on 26 October 2026.
