In June 2025, FTSE Russell launched the FTSE Climate Collective Transition EMU Broad Government Bond Index, developed in collaboration with ING and Robeco. Robeco subsequently launched the Robeco Climate Euro Government Bond UCITS ETF.

The index looks to support global investors with more informed choices to direct capital toward countries with credible climate action, improving sovereign debt portfolios' climate risk profile and supporting decarbonisation.

Featuring 55 indicators and metrics, primarily sourced from the ASCOR (Assessing Sovereign Climate-related Opportunities and Risks) tool produced by the TPI Centre at LSE and complemented by selected third-party datasets, it delivers a decision-useful sovereign climate transition index.

The index measures the performance of fixed-rate, local currency EMU (euro-denominated) government bonds and applies a rules-based methodology that adjusts country weights based on each country's relative climate transition assessment score, while also increasing exposure to eligible green bonds. It targets eligible Climate Bonds Initiative-aligned or certified green bonds, rewarding transparent use-of-proceeds financing across the EMU sovereign universe.

The index features a transparent 'glidepath' — an automatic investment strategy — tracking three climate pillars: ambition, policy, and evidence. Over time, this shifts emphasis from commitments and policies toward demonstrated real-world outcomes.
