This chapter summarises the main findings of the book: international economic institutions address climate issues through economisation, yet there are differences in how exactly this economisation defines the issue at hand, differences mainly shaped by the institutional worldview of the institution and to lesser degrees by the relationship with member states. The differences were mitigated by the interaction between the institutions. The institutions were more influential regarding fossil fuel subsidies than regarding climate finance. This is due to fossil fuel subsidy reform resonating more with domestic actors than climate finance due to its positive fiscal impact (unlike climate finance that constitutes expenditure) and closer fit with neoclassical economics. These findings are discussed in the wider perspective of economic institutions and climate politics, arguing that economisation does not lead to a paradigm shift away from established practices of environmental politics. Furthermore, the economisation of climate finance and fossil fuel subsidy reform does not necessarily entail an overarching paradigm shift within the institutions, which continue with unsustainable practices such as political and economic support to fossil fuel production and consumption.
