Climate CV


Many of us are aware of the fact that flying is one of the main contributors to the global climate breakdown. Still, many of us fly. Especially we as scientists have – ostensibly – various reasons to fly: We fly to conferences to present talks or posters, we are invited to present our work as keynote speakers, or we simply meet with fellow scientists to discuss future grant proposals. All in the knowing that this behaviour is highly problematic, resulting in a climate footprint that is beyond any scale of sustainability.

The idea of this climate CV originated from discussions in the research group “Environmental Psychology” located at the University of Koblenz-Landau, Germany. We invite scientists of all disciplines to think about their behaviour, and to create, provide, and discuss their own climate CV. With being transparent in our own ranks, we hope to contribute to a society that questions the necessity of flying.

We also hope to contribute to a shift in mental as well as material infrastructures that make scientific meetings more compatible with strong sustainability concerns and our meta-goal of decreasing emissions.


Climate CV Karen Hamann (updated May 2019)

In my scientific work and workshops on environmental psychology, I meet many environmental activists. From my first workshop on, I noticed the effect of being authentically pro-environmental and having authentic contact with participants. This made me realize how much other people inspire me who act according to their values (especially in my close surroundings).

Flying less may be one of the hardest steps to take for an environmentally just world because it partially opposes our global worldview and the urge to explore the world and meet people from all around. However, as it is one of the big points of pro-environmental behaviour, I cannot authentically advocate environmental protection and at the same time disregard it in such a dramatic manner. My last flight was in 2014. Alternative environmentally-friendly concepts of conferences and cooperation across the world will only arise if we have to become creative.

This lists conferences/meetings/talks/scientific stays. Overall, about 11.500km* were travelled, resulting in CO2 emissions of approximately 422kg**. This compares to emissions from driving a mid-sized car for approx. 1.610kg and flying by airplane for approx. 6.013kg (including 2 conferences that I cancelled/ visited via video conference due to long travel times without airplane). The sustainable yearly climate budget for a human being is estimated to be 2.300kg.

I would also like to acknowledge that my decision to travel mostly by train and bus let me focus on conferences and meetings nearby since far-away international conferences are linked to long travel durations and effort.
