Political, economic, and psychological barriers to an effective climate treaty and sustainable energy: The PEP triangle

The climate change issue has constituted an ongoing political struggle since the first formal international climate negotiations were initiated in 1992 in Rio. It is crucial to understand and solve this collective action problem to pave the road for an effective climate treaty in the future. Thus, we raise the following main research question: How should the political, economic and psychological barriers to an effective climate treaty and sustainable energy be modelled? This 'PEP Triangle' may be applied to better understand and thus improve the ongoing climate negotiations and sustainability. For example, the PEP Triangle may be used in green diplomacy and assist the European External Action Service (EEAS) in accomplishing an effective Paris Treaty.
