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.
We would like to thank all participants for their cooperation!
