Tori Tsui

Tori Tsui (born 25 October 1994) is a New Zealand-born climate activist, author, artist and model based in England. She is known for her advocacy on climate justice, mental health and youth participation in environmental movements.

Tsui has campaigned against fossil fuel expansion and has represented youth activists at United Nations climate conferences. In 2023, she authored It's Not Just You, a book exploring the relationship between mental health and climate change.

Early life and education Tsui was born in Auckland, New Zealand and was raised in Hong Kong. She graduated in 2015 with a master of research in ecology, evolution and conservation from Imperial College London with the intention of completing a PhD.

After deferring further studies, she moved to Bristol to work in the natural history documentary industry. During this time, Tsui was scouted to be a presenter, but left wildlife filmmaking after working on BBC Two's Springwatch.

McCartney subsequently sponsored Tsui to sail across the Atlantic to COP25 as part of 'Sail to the COP', a think tank initiative supporting 36 young people to attend the 2019 United Nations Climate Change Conference in Santiago. Due to civil unrest in Chile, the summit was relocated to Madrid. While in Martinique, the delegates worked remotely on COP25 before their ship finally docked in Cartagena. The project was later rebranded as 'Unite for Climate Action', and was supported by the German Government in 2020.

In 2021, Tsui launched the 'Pass the Mic' initiative with Dominique Palmer, Elijah McKenzie-Jackson and others as a way to draw greater attention to the climate crisis. The campaign was focused on targeting brands, public figures and organisations to spotlight frontline climate activists and communities affected by climate change. It was started in response to David Attenborough's office retiring his Instagram account of 6.2 million followers.

Tsui has also supported the "Stop Cambo" campaign against North Sea oil and gas expansion, including leading a protest against Dutch businessman Ben Van Beurden at the 2021 TED Countdown summit in Edinburgh.

Later that year, she attended the 2021 United Nations Climate Change Conference in Glasgow. Emma Watson invited Tsui to participate in a New York Times COP26 Hub event alongside Amanda Gorman, Malala Yousafzai, Greta Thunberg, Vanessa Nakate, Dominique Palmer, Mya-Rose Craig, Daphne Frias and Ati Viviam Villafaña.

Tsui was featured in British Vogue as part of the Women 25 cohort featuring RAYE, Jodie Comer, Cora Corre and Lila Moss. She has also won awards and been featured in Elle Magazine and Cosmopolitan Magazine and received the Tenacious Award for her campaigning.

As a collaborator of Billie Eilish, in January 2023 Tsui was invited to appear on the digital front cover of Vogue with Eilish, Quannah Chasinghorse, Xiye Bastida, Isaias Hernandez, Nalleli Cobo, Wawa Gatheru, Maya Penn and Ryan Berberet.

Tsui works on the "Stop Rosebank" coalition as partnerships consultant. In January 2025, the campaign won their court case against Ithaca Energy and Equinor. Tsui also works as the climate justice lead on Brian Eno's organisation 'EarthPercent', and has been linked to both In Place of War's 'Earth Sonic' initiative and Climate Live.

She is a senior adviser to the Fossil Fuel Non-Proliferation Treaty Initiative. She spearheaded a Treaty endorsement from Andy Burnham and Massive Attack, involving a public stunt on top of the Greater Manchester Combined Authority, and subsequently spoke on stage at Massive Attack's show at the Co-op Live Arena. Tsui also worked on an Artist's endorsement letter featuring Brian Eno, Robert Smith, Jameela Jamil and Jane Fonda. She is an ambassador for Zero Hour. In that role, she has campaigned for environmental law reform, including the Climate and Nature Bill.

Tsui has spoken at events hosted by UNICEF, Oxfam, TED xLondon, SXSW, Glastonbury Festival, Columbia University and Global Citizen where she spoke at the G20 on the need for a Fossil Fuel Treaty.

Publications

Tsui released her debut book in 2023, It's Not Just You: How to Navigate Eco-Anxiety and the Climate Crisis. The book examines eco-anxiety and the mental health impacts of the climate crisis, arguing for collective approaches to care and action.

The book was shortlisted for the 2024 Wainwright Prize for Writing on Conservation and was recommended by Waterstones as a "Best Book" in 2023 (on popular science). In April 2026, It's Not Just You was released in the USA through The New Press.
