We study the effect of leadership in an experimental threshold public "bad" game, where we manipulate both the relative returns of two investments (the more productive of which causes a negative externality) and the extent to which the gains from leadership diffuse to the group. The game...

Achieving the Paris Agreement long-term temperature goal requires closing the ambition and action gap. G20 countries have a crucial role to play in realising increased climate policy ambition. Synthetic electro fuels (e-fuels) were identified as one of the key policy areas and promising options...

Multilateral cooperation initiatives (or “climate clubs”) can generate some of the additional action that is needed to achieve the goals agreed in the Paris Agreement. An analysis of the state of collaboration in the four policy areas energy transition, synthetic fuels, food systems and...

Recent international climate negotiations suggest that complete agreements are unlikely to materialize. Instead, partial cooperation between like-minded countries appears a more likely outcome. In this paper we analyze the effects of such partial cooperation between like-minded countries. In...

To increase climate policy ambitions and achieve carbon neutrality, countries need to take much more ambitious action already in the coming decade. One of the key areas of action is the transformation of our food systems towards sustainability. In this regard, two aspects stand out as having a...

Achieving the Paris Agreement long-term temperature goal requires efforts for rapidly reducing GHG emissions while also increasing CO2 removals by sinks. G20 countries have a crucial role to play in increasing climate policy ambition. Land use change contributes 15 % of current global...
