EU CO₂ certificates: Thank you to participants!

As part of a research project, we experimentally investigated the willingness to take collective action in the context of global climate change. To this end, we conducted a laboratory experiment in November and December 2024.
In the experiment, the participants were explicitly informed that their decisions would be used to finance real emission reductions after completion – specifically through the purchase of EU CO₂ certificates.
The certificates were purchased through the organization Compensators e.V. In total, certificates worth €1,575.75 were purchased, which corresponds to 16.61 tonnes of CO₂ at a price of €94.88 per tonne.
The certificates can be viewed here.

The results of the study have now been published in Scientific Reports and are available here.

We would like to thank all participants for their cooperation!
