BBC Earth’s new documentary series, Greta Thunberg: A Year to Change the World, follows the world’s most iconic climate activist

BBC Earth brings viewers the highly-anticipated and revealing series following climate activist Greta Thunberg as she seeks to raise awareness of the accelerating climate change in Greta Thunberg: A Year to Change the World (3×60’). Over the course of the three-part documentary series, Greta travels to extraordinary locations across the globe where the impact of a changing climate is becoming apparent, both for the planet and the human costs. From Alberta, Canada’s oil sands and melting glaciers to the coal mines of Europe, the documentary shines a light on the first-hand consequences of greenhouse gas emissions. Throughout Greta’s journey, she meets with a range of academics, economists and leading climate scientists to confront the complexity of what is required to make change happen, exploring the role advanced technology and all of us could play in helping to limit global warming. Greta Thunberg: A Year to Change the World airs in its entirety as a special on Earth Day, Thursday, April 22 at 8 p.m. ET / 5 p.m. PT exclusively on BBC Earth in Canada. BBC Earth is also available on Amazon Prime Video with Greta Thunberg: A Year to Change the World airing simultaneously on this platform in its entirety on April 22 from 8 p.m. ET / 5 p.m. PT.

Filming for Greta Thunberg: A Year to Change the World began in Autumn 2019 when 16 year-old Greta took a year off from school to embark on an international mission to spread her message on a global stage, transfixing the world as she challenged those in 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.
