All three institutions have framed climate finance in economic terms and stressed normative ideas such as efficiency. They have also linked climate finance to issues such as fossil fuel subsidies, carbon pricing, risk and investment to a larger degree than environmental institutions. Despite the overarching convergence between the institutions around addressing climate finance as an economic issue rather than an issue of environmental protection or global justice, the institutions also diverged on climate finance to some degree. The divergence is most notable regarding whether carbon pricing should constitute a source of climate finance, and to some extent also regarding how equity should be prioritised. Subsequently, this chapter explains this alignment in terms of economic worldviews and interaction pulling towards convergence. Divergence between the institutions has been driven less by fundamental differences in worldviews (e.g. between the OECD Development Directorate and the IMF) and the degree of autonomy from member states. Finally, the consequences of the output are described, identifying more significant (cognitive) influences at the international level than the domestic level, but also incentive-based influences from the OECD and the G20.
