An Assessment of the Past Performance and the Future Role of the High Ambition Coalition

Autore: Michael Schneider

In 2015, the High Ambition Coalition (HAC), an amalgamation of developed and developing countries, entered the world stage at COP21 in Paris. This paper assesses the past and future role of the HAC in climate governance based on wider considerations as part of a master thesis. For this purpose, it is drawn from relevant findings from coalition and negotiation theory, game theory, behavioural economics and experimental games, and the consideration of climate clubs in international relations. Based on a negotiation analysis, the past performance of the HAC is evaluated positively. However, the analysis of national climate policies reveals many challenges. The potential to turn into a ‘transformational climate club’, a ‘coalition of the willing’ with ambitious climate policies framed around a common vision and common benefits, can only be realised if certain enthusiastic HAC members are willing to lead and increase their ambition.
