Greta Tintin Eleonora Ernman Thunberg (born 3 January 2003) is a Swedish environmental activist who is internationally known for challenging world leaders to take immediate action against climate change. Thunberg initially gained notice for her youth and her straightforward speaking manner, both in public and to political leaders and assemblies, in which she criticises world leaders for their failure to take what she considers sufficient action to address the climate crisis.

Thunberg's activism started after convincing her parents to adopt several lifestyle choices to reduce their own carbon footprint. In August 2018, at age 15, she started spending her school days outside the Swedish Parliament to call for stronger action on climate change by holding up a sign reading Skolstrejk för klimatet (School strike for climate). Soon, other students engaged in similar protests in their own communities. Together, they organised a school climate strike movement under the name Fridays for Future. After Thunberg addressed the 2018 United Nations Climate Change Conference, student strikes took place every week somewhere in the world. In 2019, there were multiple coordinated multi-city protests involving over a million students each. To avoid flying, Thunberg sailed to North America where she attended the 2019 UN Climate Action Summit. Her speech there, in which she exclaimed "how dare you", was widely taken up by the press and incorporated into music.

Her sudden rise to world fame has made her both a leader and a target for critics. Her influence on the world stage has been described by The Guardian and other newspapers as the "Greta effect". She has received numerous honours and awards including an honorary Fellowship of the Royal Scottish Geographical Society, inclusion in Time's 100 most influential people, being the youngest Time Person of the Year, inclusion in the Forbes list of The World's 100 Most Powerful Women (2019), and two consecutive nominations for the Nobel Peace Prize (2019 and 2020).

I Am Greta

The story of teenage climate activist Greta Thunberg is told through compelling, never-before-seen footage in this intimate documentary about a young girl who has become the voice of a generation.

Starting with her one-person school strike for climate justice outside the Swedish Parliament, the film follows Greta - a shy student with Asperger’s - as she rises to prominence, and her galvanising global impact as she sparks school strikes around the world.

The film culminates with her gruelling wind-powered voyage across the Atlantic Ocean to speak at the UN Climate Action Summit in New York City. En route, in an intensely emotional moment, Greta reflects on the enormous toll her mission has exacted.



No One Is Too Small to Make a Difference is a book by climate activist Greta Thunberg. It was published on 30 May 2019. It consists of a collection of eleven speeches which she has written and presented about global warming and the climate crisis.

Greta Thunberg has presented the speeches in front of the UN, the EU, the World Economic Forum and during demonstrations and protests. One of her most famous speeches which appears in the book, is "Our House Is on Fire".

An expanded edition was published on 21 November 2019 with five new speeches. 


Right Livelihood Award ...for inspiring and amplifying political demands for urgent climate action reflecting scientific facts

The Swedish climate activist Greta Thunberg was born on 3 January 2003 in Stockholm. Growing up in times of an undeclared climate emergency, Thunberg had the urge to grasp the causes and effects of climate change at an early age. Worried about the dramatically widening gap between the urgency to act and the indifference of politicians around the world, she found a way to demand climate action that inspired a global movement.

Greta Thunberg is a teenage climate activist from Sweden. She is the powerful voice of a young generation that will have to bear the consequences of today’s political failure to stop climate change. Her resolve to not put up with the looming climate disaster has inspired millions of peers to also raise their voices and demand immediate climate action.

In August 2018, with the Swedish Parliamentary election only weeks away, 15-year old Greta Thunberg saw with despair how politicians lacked strategies to combat climate change – if they even cared at all about the issue. Knowing that the life of present and future generations depend on limiting global warming to 1.5 degrees above pre-industrial levels, Thunberg took matters in her own hands. She went on “school strike for climate” outside the Swedish Parliament.

The initiative was picked up widely both online and in the media, and young activists joined Thunberg outside the Parliament building. Others organised school strikes elsewhere. The movement #FridaysForFuture was born and millions of people – young and old – have taken to the streets since.

Driven by her scientific understanding of the climate crisis and the insufficient response of politics and society to the problem, it became Thunberg’s mission to promote action against climate change. She personifies the notion that everyone has the power to create change. Her example has inspired and empowered people from all walks of life to demand political action.

Thunberg continues to tirelessly convey her message: acknowledge the facts, realise the urgency of the climate crisis and act accordingly. She speaks at high-level conferences, meets world leaders, and gives guidance to a growing global movement.

Many people before Thunberg have tried to convey the urgency of immediate climate action. No one has been more successful. Her uncompromising way to speak truth to power resonates with the public. Greta Thunberg has managed to get the climate crisis not only on the cover page of newspapers but also on top of people’s minds.
