Climate protection is a problem of sustaining a public resource that everybody is free to overuse, as it emerges in many social dilemmas.

We perform a new type of ‘public goods experiment’ with human subjects contributing to a public pool. In contrast to the standard protocol, here the common pool is not divided among the participants; instead, it is promised that the pool will be invested to encourage people to reduce their fossil fuel use.

Our experiments demonstrate that ‘players’ can behave altruistically to maintain the Earth’s climate given the right set of circumstances. Both, to invest publicly, thus gaining social reputation, and the need to reach an additional intermediate collective target to prevent climate risks, such as floods or draughts, can increase contributions substantially. Even the missing cooperative interaction of rich and poor, which caused the failure of the Copenhagen climate summit, can be catalyzed by intermediate climate targets.

The event starts with a snack and refreshments in advance of the lecture that begins at 16.15 at Vil Vite, Tormøhlensgt. 55, Tuesday 26 of August.

The lecture is open to all. Welcome!
