My PhD research addresses research gaps on major climate-change action enablers and explores how these enablers have performed over time and across countries. Moreover, it develops research and policy-making tools to further analyse these enablers and to leverage their potential to boost climate-change action. The major enablers that I address in my thesis, are: key moments in international climate negotiations; country contexts and the common but differentiated responsibilities and respective capabilities (CBDR-RC) principle; international climate assistance; and policy coherence for the joint implementation of climate targets and the sustainable development goals (SDGs). In this context, I discuss four policy coherence types: coherence between national and international action; coherence between sources of finance; socio-economic and environmental coherence; and coherence between international policy agendas.
