Commissioned for BBC One and BBC iPlayer and co-produced with PBS, this revealing series follows environmental activist Greta Thunberg as she seeks to raise awareness of the accelerating climate change and spread her message, that we must act to drastically reduce our carbon emissions.

Over the course of three episodes, Greta explores the science as she travels to extraordinary locations across the globe where the impact of a changing climate is glaringly obvious both for the planet and for the inevitable human costs.

From the burning tar sands of the Canadian Oil Industry to the coal mines of Europe and the melting glaciers of the USA, she witnesses first hand the consequences of climate change and makes clear the reasons why she thinks something must be done.

On her journey she meets leading climate scientists and confronts the complexity of what is required to make change happen exploring possible actions and technology that could help limit global warming, from advanced technology to the role all of us can play. The series also hears from a range of academics, economists and experts, further exploring the climate change science Greta encounters on the ground.

Filming started in Autumn 2019 when then sixteen-year-old Greta took a year off school to embark on an international mission to spread her message and the world was transfixed as this teenager spoke truth to power, from diplomats at the United Nations to the world’s economic elite at Davos. As the Covid-19 pandemic brought the world to a standstill, the cameras continued filming with Greta at home in Sweden.
