Klimaticket, which translates to "climate ticket," is aimed at discouraging "motorized individual transport" and bringing the country closer to its climate change goals under the Paris Agreement.
Campaign officials said six people have thus far taken the offer and gotten Klimaticket tattoos in exchange for free tickets. They said several more people received free tattoos with various environmental themes, but all they received for them was the tattoo itself.
Leonore Gewesseler, a member of parliament with the Green party and the country's climate minister, was criticized by some for promoting the tattoo offer at the Frequency Festival.
Henrike Brandstötter, a member of parliament for the NEOS party, said on social media that "offering people money for putting advertising under their skin reveals an unacceptable view of humanity from a government minister."
Gewessler said the tattoos are only offered during the daylight hours, when festival-goers are less likely to be intoxicated, and the tattoo artists ensure that every recipient is over age 18.
