Which Countries are Particularly Vulnerable? Science Doesn’t Have the Answer!

The document examines the ambiguity surrounding the term 'particularly vulnerable' within the UNFCCC framework and argues that vulnerability indices cannot provide an objective truth for prioritising adaptation finance. It asserts that because vulnerability is a socially constructed concept requiring normative judgments on variables and weighting, the responsibility for defining and ranking vulnerable countries lies with political negotiators rather than scientists.

• There is a lack of consensus and systematic agreement among UNFCCC Parties on how to assess, measure, or compare the vulnerability of countries, leading to ambiguity in the prioritisation of adaptation finance.
• Vulnerability is not an objective, quantifiable attribute; instead, any assessment of it is a socially constructed outcome of negotiations that reflects biased interpretations.
• The creation of a vulnerability index requires normative decisions—such as selecting variables, assigning weights, and setting thresholds—which are political tasks that scientists cannot resolve.
• Different international agreements and frameworks have provided inconsistent or evolving interpretations of which countries are 'particularly vulnerable'.
• Any single vulnerability index is likely to be contested by countries that are not ranked as 'particularly vulnerable' and thus lose priority for adaptation funding.
