Renowned Climate Researcher Faces Termination from University for Taking Stand Against Air Travel

Climate researcher Dr. Gianluca Grimalda faces the potential loss of his position at the Kiel Institute for the World Economy in Germany due to his refusal to use air travel for his return journey from Papua New Guinea. Grimalda's objective is to decrease his carbon emissions by 90%, and he intends to achieve this by opting for alternative modes of transportation such as ferries, coaches, trains, and cargo ships for his journey back to Germany.

According to a statement from climate group Scientist Rebellion, he mentioned that the institute only gave him three days' notice to return by October 2, which would have required him to fly. Grimalda informed CNN that the Kiel Institute informed him to anticipate a second warning to travel by plane if he didn't return, and if he fails to do so again, they will proceed with issuing the letter of redundancy.

He stated that his salary for September has not been received and his request for unpaid leave has been declined. The Kiel Institute informed CNN that it does not publicly discuss internal personnel issues but provides support to its employees for eco-friendly travel while on business trips.

The Kiel Institute declined to comment on Grimaldas' allegation of unpaid salary in September, citing the protection of their employees as the reason for not discussing internal personnel matters.

Grimalda, an experimental economist and campaigner for Scientist Rebellion, conducted fieldwork in Bougainville, Papua New Guinea for six months. His research focused on examining the interconnection between globalization, climate change, and social cohesion.

Although Grimalda's permission for travel expired on September 10, his research extended beyond the initially anticipated timeframe. This was primarily due to multiple security threats, notably an incident where he was held captive by a group armed with machetes. During the ordeal, all of his belongings were confiscated, as asserted by Scientist Rebellion in their statement.

As the climate crisis escalates, the environmental impact of aviation is facing closer examination. Commercial aviation is responsible for 2.5% of global CO2 emissions annually, and it is anticipated that both flight demand and emissions will significantly rise in the future. In response, climate activists like Greta Thunberg have advocated for eco-friendly modes of travel such as ships and trains.

Grimalda stated, "I am willing to accept any legal and economic consequences that may arise from this decision. Additionally, it is crucial to consider the impact on mental health. I personally experience climate anxiety, and flying only exacerbates this condition."

Grimalda completed a 15,000-kilometer (9,321-mile) overland journey from Germany to Papua New Guinea earlier this year, taking him 35 days. Currently, he remains in Papua New Guinea until he embarks on a cargo ship on October 8 for his return voyage to Germany.
