Core objective: Evaluate progression of the sovereign ESG landscape since the 2021 study “Demystifying Sovereign ESG” by conducting a comparative analysis of the current sovereign ESG methodologies of commercial ESG providers.
Central takeaways:
- The 2021 study highlighted the distinct nature of the sovereign ESG segment from corporate ESG and documented fundamental shortcomings in sovereign ESG methodologies, including the “ingrained income bias”, lack of consensus on environmental performance, and conflation of risk and sustainability objectives.
- While sovereign ESG methodologies have evolved since 2021, the significant correlation across providers of aggregate, S, and G scores persist.
- There has been a notable shift towards greater focus on the E pillar in response to market demand, accompanied by growing heterogeneity on climate and environmental considerations across ESG providers.
- The findings underscore the disparity between perceptions and realities in implementing a sustainability strategy within the sovereign debt asset class.
- The paper calls for a reevaluation of sovereign ESG scoring methodologies towards outcome-based metrics and urges a globally coordinated effort to establish robust sustainability measurement frameworks.

Persisting correlations:
- Significant correlation across providers of aggregate, S, and G scores persists.
Shifts in emphasis:
- Market demand has driven a notable shift towards greater focus on the E pillar.
Heterogeneity and disagreement:
- Growing heterogeneity on climate and environmental considerations across ESG providers.
Perception vs. reality:
- Disparity exists between perceptions and realities in implementing sustainability strategies in the sovereign debt asset class.

Documented shortcomings from 2021 that remain relevant:
- “ingrained income bias”
- lack of consensus on environmental performance
- conflation of risk and sustainability objectives
Implication:
- Current sovereign ESG scoring methodologies may not adequately reflect outcome-based sustainability performance.

Reevaluate sovereign ESG scoring methodologies with an emphasis on:
- Moving toward outcome-based metrics.
Global coordination:
- Urge a globally coordinated effort to establish robust sustainability measurement frameworks.
