Born	30/12/1971 Milan, Italy
Alma mater	Bocconi University, University of Southampton, University of Pavia
Occupation(s)	Researcher, climatologist, economist

Gianluca Grimalda is an Italian social scientist. Concerned about the effects of climate change and social cohesion, he came to public attention when he refused to travel by plane on business because of the climate impact of air travel. This refusal was followed by dismissal by his employer, the Kiel Institute for the World Economy (IfW Kiel).

Biography

Studies and works

Grimalda obtained a degree in economics from Bocconi University and doctorates from the University of Pavia and the University of Southampton in 2003. He worked as a researcher at the Kiel Institute for the World Economy until his dismissal in October 2023. ^[1]

From January to June 2024, Grimalda was a visiting professor at the University of Passau.

Grimalda's research focuses on social cohesion and how societies adapt to macro-factors of change such as global warming and globalization. His field research took him to Bougainville, Papua New Guinea, where he studied people's willingness to help each other in degraded conditions caused by climate change.

Commitment to climate protection

Grimalda has actively participated in protest actions, notably as part of Scientist Rebellion, and has campaigned for civil disobedience as a means of promoting climate protection. Among other things, in October 2022 he and other scientists glued themselves to the floor for forty hours in the pavilion of the Porsche museum in Wolfsburg, this Volkswagen owned location is targeted to echo the Dieselgate. In November of the same year, the researcher also took part in an international blockade of private jets airports. ^[2]

Grimalda always travels avoiding the use of aircraft in favour of more climate friendly means of transport such as boats, trains and buses. This attitude reflects his convictions on the ethics of aviation in the face of the climate crisis and indirectly led to his being ousted from his post at the Institute for World Economics in Kiel. Field research in Papua New Guinea had been extended due to unforeseen circumstances, so the institute had asked him to return within ten days or face dismissal. His return journey took 35 days due to renouncing air travel. Nine thousand scientists from all over Europe signed a petition calling for him to remain at the Institute for World Economics. An initial action against his dismissal was brought before the Kiel Labour Court, but was unsuccessful. Subsequently, on 10 January 2025, the Kiel Labour Court handed down its verdict: the institute would compensate the researcher, but would not re-employ him, on the grounds of ‘incompatibility of the parties' ideological convictions’.

" I would have liked my job back, but this is already a first step in the legal recognition of conscientious objection on climate grounds "

Employment law

He is known as the first employee to be dismissed and then compensated, in connection with the fight against climate change. ^[3]

Documentary

In June 2024, Paolo Casalis's documentary The Researcher premiered at the Cinemambiente Festival. It depicts Grimalda's journey to Papua New Guinea in 2023: at the end of his research work, Grimalda is dismissed for refusing to take a plane. As he begins the journey home, his story and his application of ‘slow travel’ become known and viral on social networks. ^[4] The film won the Award for Best Educational Work at the Frome Climate Film Festival (UK) in May 2025. ^[5]

Book

Grimalda wrote a book about his story, published in June 2025 in Italian by the publishing house Feltrinelli. ^[6] The book, titled "A fuoco" (which can be translated as either "Burning up" or "Zooming in") is the diary of the 72 days/28,000 km no-fly journey from Bougainville to Germany. Grimalda intertwines the chronicle of his journey with the testimonies of people he met in their struggle to adapt to climate change. The book also offers scientific information on the ecosystem stability of some of the places he travelled through.
